Goldwater Range, West in southwestern Arizona encompasses 2,808 square kilometers of Sonoran Desert. The hyper-arid range has an annual rainfall of less than 10 cm with an average high temperature of 41 degrees Celsius in July to an average low of 4 degrees Celsius in January. The range shares approximately 60 kilometers of the international border with Mexico. A majority of the range is open for recreational use, primarily off-highway vehicles. Because of its proximity to Mexico, the range is also heavily patrolled by U.S. Customs and Border Protection seeking to intercept and apprehend inadmissible people and illicit goods. Decades of off-roading and Border Patrol activities have negatively impacted this sensitive desert ecosystem. To assist the range program managers, this study is developing a model to identify erosion prone areas and calibrate the model’s parameters using the Automated Geospatial Watershed Assessment modeling tool. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arid%20lands" title="arid lands">arid lands</a>, <a href="https://publications.waset.org/abstracts/search?q=automated%20geospatial%20watershed%20assessment" title=" automated geospatial watershed assessment"> automated geospatial watershed assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=erosion%20modeling" title=" erosion modeling"> erosion modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=sedimentation%20modeling" title=" sedimentation modeling"> sedimentation modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=watershed%20modeling" title=" watershed modeling"> watershed modeling</a> </p> <a href="https://publications.waset.org/abstracts/59846/modeling-of-erosion-and-sedimentation-impacts-from-off-road-vehicles-in-arid-regions" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/59846.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">374</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4124</span> Modeling of Water Erosion in the M'Goun Watershed Using OpenGIS Software</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=M.%20Khal">M.

Modeling water erosion requires the use of software and GIS programs, commercial or closed source. The very high prices for commercial GIS licenses, motivates users and researchers to find open source software as relevant and applicable as the proprietary GIS. The objective of this study is the modeling of water erosion and the hydrogeological and morphophysical characterization of the Oued M'Goun watershed (southern flank of the Central High Atlas) developed by free programs of GIS. The very pertinent results are obtained by executing tasks and algorithms in a simple and easy way. Thus, the various geoscientific and geostatistical analyzes of a digital elevation model (SRTM 30 m resolution) and their combination with the treatments and interpretation of satellite imagery information allowed us to characterize the region studied and to map the area most vulnerable to water erosion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=central%20High-Atlas" title="central High-Atlas">central High-Atlas</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrogeology" title=" hydrogeology"> hydrogeology</a>, <a href="https://publications.waset.org/abstracts/search?q=M%E2%80%99Goun%20watershed" title=" M’Goun watershed"> M’Goun watershed</a>, <a href="https://publications.waset.org/abstracts/search?q=OpenGis" title=" OpenGis"> OpenGis</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20erosion" title=" water erosion"> water erosion</a> </p> <a href="https://publications.waset.org/abstracts/99290/modeling-of-water-erosion-in-the-mgoun-watershed-using-opengis-software" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99290.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">159</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4123</span> Modeling of Sediment Yield and Streamflow of Watershed Basin in the Philippines Using the Soil Water Assessment Tool Model for Watershed Sustainability</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Warda%20L.%20Panondi">Warda L.

In the Philippines, the Pulangi watershed experienced a high sediment loss mainly due to land conversions and plantations that showed critical erosion rates beyond the tolerable limit of -10 ton/ha/yr in all of its sub-basin. From this event, the prediction of runoff volume and sediment yield is essential to examine using the country's soil conservation techniques realistically. In this research, the Pulangi watershed was modeled using the soil water assessment tool (SWAT) to predict its watershed basin's annual runoff and sediment yield. For the calibration and validation of the model, the SWAT-CUP was utilized. The model was calibrated with monthly discharge data for 1990-1993 and validated for 1994-1997. Simultaneously, the sediment yield was calibrated in 2014 and validated in 2015 because of limited observed datasets. Uncertainty analysis and calculation of efficiency indexes were accomplished through the SUFI-2 algorithm. According to the coefficient of determination (R2), Nash Sutcliffe efficiency (NSE), King-Gupta efficiency (KGE), and PBIAS, the calculation of streamflow indicates a good performance for both calibration and validation periods while the sediment yield resulted in a satisfactory performance for both calibration and validation. Therefore, this study was able to identify the most critical sub-basin and severe needs of soil conservation. Furthermore, this study will provide baseline information to prevent floods and landslides and serve as a useful reference for land-use policies and watershed management and sustainability in the Pulangi watershed. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pulangi%20watershed" title="Pulangi watershed">Pulangi watershed</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment%20yield" title=" sediment yield"> sediment yield</a>, <a href="https://publications.waset.org/abstracts/search?q=streamflow" title=" streamflow"> streamflow</a>, <a href="https://publications.waset.org/abstracts/search?q=SWAT%20model" title=" SWAT model"> SWAT model</a> </p> <a href="https://publications.waset.org/abstracts/133502/modeling-of-sediment-yield-and-streamflow-of-watershed-basin-in-the-philippines-using-the-soil-water-assessment-tool-model-for-watershed-sustainability" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/133502.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">209</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4122</span> Modeling and Monitoring of Agricultural Influences on Harmful Algal Blooms in Western Lake Erie</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Xiaofang%20Wei">Xiaofang Wei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Harmful Algal Blooms are a recurrent disturbing occurrence in Lake Erie that has caused significant negative impacts on water quality and aquatic ecosystem around Great Lakes areas in the United States. Targeting the recent HAB events in western Lake Erie, this paper utilizes satellite imagery and hydrological modeling to monitor HAB cyanobacteria blooms and analyze the impacts of agricultural activities from Maumee watershed, the biggest watershed of Lake Erie and agriculture dominant.SWAT (Soil & Water Assessment Tool) Model for Maumee watershed was established with DEM, land use data, crop data layer, soil data, and weather data, and calibrated with Maumee River gauge stations data for streamflow and nutrients. Fast Line-of-sight Atmospheric Analysis of Hypercubes (FLAASH) was applied to remove atmospheric attenuation and cyanobacteria Indices were calculated from Landsat OLI imagery to study the intensity of HAB events in the years 2015, 2017, and 2019. The agricultural practice and nutrients management within the Maumee watershed was studied and correlated with HAB cyanobacteria indices to study the relationship between HAB intensity and nutrient loadings. This study demonstrates that hydrological models and satellite imagery are effective tools in HAB monitoring and modeling in rivers and lakes. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=harmful%20algal%20bloom" title="harmful algal bloom">harmful algal bloom</a>, <a href="https://publications.waset.org/abstracts/search?q=landsat%20OLI%20imagery" title=" landsat OLI imagery"> landsat OLI imagery</a>, <a href="https://publications.waset.org/abstracts/search?q=SWAT" title=" SWAT"> SWAT</a>, <a href="https://publications.waset.org/abstracts/search?q=HAB%20cyanobacteria" title=" HAB cyanobacteria"> HAB cyanobacteria</a> </p> <a href="https://publications.waset.org/abstracts/140628/modeling-and-monitoring-of-agricultural-influences-on-harmful-algal-blooms-in-western-lake-erie" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/140628.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">176</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4121</span> Assessment of Sustainability in the Wulo Abiye Watershed, Central Highlands of Ethiopia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Getabalew%20Derib">Getabalew Derib</a>, <a href="https://publications.waset.org/abstracts/search?q=Arragaw%20Alemayehu"> Arragaw Alemayehu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Assessing the sustainability of watersheds holds significant importance for regional natural resource management and to achieve sustainable development. This study investigated the sustainability of the Wulo Abiye watershed, central highlands of Ethiopia. The sustainability status of the watershed was evaluated by using 17 indicators representing the economic, social, and environmental dimensions of sustainable development goals (SDGs) based on the local and existing conditions of the watershed. The results indicated that environmental sustainability was at a ’ high’ level, while social and economic sustainability and the aggregate index were at ‘moderate’ levels. The overall level of community participation in the planning and evaluation phases of watershed management was at ’low’ levels. The implementation phase was at ’high’ level. Overall , the sustainability status of watershed management and level of community participation were at ‘moderate’ levels.

But most watersheds in Ethiopia are increasingly facing the threats of degradation due to both natural and man-made causes. To reverse these problems, communities’ participation in sustainable management programs is among the necessary measures. Hence, this study assessed the households’ willingness to pay for watershed management practices through a contingent valuation study approach. Double bounded dichotomous choice with open-ended follow-up format was used to elicit the households’ willingness to pay. Based on data collected from 275 randomly selected households, descriptive statistics results indicated that most households (79.64%) were willing to pay for watershed management practices. A bivariate Probit model was employed to identify determinants of households’ willingness to pay and estimate mean willingness to pay. Its result shows that age, gender, income, livestock size, perception of watershed degradation, social position, and offered bids were important variables affecting willingness to pay for watershed management practices. The study also revealed that the mean willingness to pay for watershed management practices was calculated to be 58.41 Birr and 47.27 Birr per year from the double bounded and open-ended format, respectively. The study revealed that the aggregate welfare gains from watershed management practices were calculated to be 931581.09 Birr and 753909.23 Birr per year from double bounded dichotomous choice and open-ended format, respectively. Therefore, the policymakers should make households to pay for the services of watershed management practices in the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=bivariate%20probit%20model" title="bivariate probit model">bivariate probit model</a>, <a href="https://publications.waset.org/abstracts/search?q=contingent%20valuation" title=" contingent valuation"> contingent valuation</a>, <a href="https://publications.waset.org/abstracts/search?q=watershed%20management%20practices" title=" watershed management practices"> watershed management practices</a>, <a href="https://publications.waset.org/abstracts/search?q=willingness%20to%20pay" title=" willingness to pay"> willingness to pay</a> </p> <a href="https://publications.waset.org/abstracts/139235/households-willingness-to-pay-for-watershed-management-practices-in-lake-hawassa-watershed-southern-ethiopia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/139235.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">224</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4119</span> Heterogeneity of Soil Moisture and Its Impacts on the Mountainous Watershed Hydrology in Northwest China</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chansheng%20He">Chansheng He</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhongfu%20Wang"> Zhongfu Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiao%20Bai"> Xiao Bai</a>, <a href="https://publications.waset.org/abstracts/search?q=Jie%20Tian"> Jie Tian</a>, <a href="https://publications.waset.org/abstracts/search?q=Xin%20Jin"> Xin Jin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Heterogeneity of soil hydraulic properties directly affects hydrological processes at different scales. Understanding heterogeneity of soil hydraulic properties such as soil moisture is therefore essential for modeling watershed ecohydrological processes, particularly in hard to access, topographically complex mountainous watersheds. This study maps spatial variations of soil moisture by in situ observation network that consists of sampling points, zones, and tributaries, and monitors corresponding hydrological variables of air and soil temperatures, evapotranspiration, infiltration, and runoff in the Upper Reach of the Heihe River Watershed, a second largest inland river (terminal lake) with a drainage area of over 128,000 km² in Northwest China. Subsequently, the study uses a hydrological model, SWAT (Soil and Water Assessment Tool) to simulate the effects of heterogeneity of soil moisture on watershed hydrological processes. The spatial clustering method, Full-Order-CLK was employed to derive five soil heterogeneous zones (Configuration 97, 80, 65, 40, and 20) for soil input to SWAT. Results show the simulations by the SWAT model with the spatially clustered soil hydraulic information from the field sampling data had much better representation of the soil heterogeneity and more accurate performance than the model using the average soil property values for each soil type derived from the coarse soil datasets. Thus, incorporating detailed field sampling soil heterogeneity data greatly improves performance in hydrologic modeling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=heterogeneity" title="heterogeneity">heterogeneity</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20moisture" title=" soil moisture"> soil moisture</a>, <a href="https://publications.waset.org/abstracts/search?q=SWAT" title=" SWAT"> SWAT</a>, <a href="https://publications.waset.org/abstracts/search?q=up-scaling" title=" up-scaling"> up-scaling</a> </p> <a href="https://publications.waset.org/abstracts/49519/heterogeneity-of-soil-moisture-and-its-impacts-on-the-mountainous-watershed-hydrology-in-northwest-china" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/49519.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">346</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4118</span> Application of Watershed Modeling System for Urbanization Management in Tabuk Area, Saudi Arabia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Abd-Alrahman%20Embaby">Abd-Alrahman Embaby</a>, <a href="https://publications.waset.org/abstracts/search?q=Ayman%20Abu%20Halawa"> Ayman Abu Halawa</a>, <a href="https://publications.waset.org/abstracts/search?q=Medhat%20Ramadan"> Medhat Ramadan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The infiltrated water into the subsurface activates expansive soil in localized manner, leading to the differential heaving and destructive of the construction. The Watershed Modeling System (WMS) and Hydrologic Engineering Center (HEC-1) are used to delineate and identify the drainage system and basin morphometry in Tabuk area, where flash floods and accumulation of water may take place. Eight drainage basins effect on Tabuk city. Three of them are expected to be high. The flash floods and surface runoff behavior in these basins are important for any protection projects. It was found that the risky areas that contain Tabuk shale could be expanded when exposed to flash floods and/or surface runoff. The resident neighborhoods in the middle of Tabuk city and affected by surface runoff of the tributaries of the basin of Wadi Abu Nishayfah, Na'am and Atanah outlet, represent high-risk zones. These high-risk neighborhoods are Al Qadsiyah, Al Maseif, Arrwdah, Al Nakhil and Al Rajhi. It can be avoided new constructions on these districts. The low or very low-risk zones include the western and the eastern districts. The western side of the city is lying in the upstream of the small basin. It is suitable for a future urban extension. The direction of surface runoff flow or storm water drain discharge should be away from Tabuk city.

Egypt and Sudan are almost dependent on water originated from the Blue Nile. This multi-dependency creates conflicts among the three countries Egypt, Sudan, and Ethiopia making the management of these conflicts as an international issue. Good assessment of the water resources of the Blue Nile is an important to help in managing such conflicts. Hydrological models are good tool for such assessment. This paper presents a critical review of the nature and variability of the climate and hydrology of the Blue Nile Basin as a first step of using hydrological modeling to assess the water resources of the Blue Nile. Many several attempts are done to develop basin-scale hydrological modeling on the Blue Nile. Lumped and semi distributed models used averages of meteorological inputs and watershed characteristics in hydrological simulation, to analyze runoff for flood control and water resource management. Distributed models include the temporal and spatial variability of catchment conditions and meteorological inputs to allow better representation of the hydrological process. The main challenge of all used models was to assess the water resources of the basin is the shortage of the data needed for models calibration and validation. It is recommended to use distributed model for their higher accuracy to cope with the great variability and complexity of the Blue Nile basin and to collect sufficient data to have more sophisticated and accurate hydrological modeling. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Blue%20Nile%20Basin" title="Blue Nile Basin">Blue Nile Basin</a>, <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title=" climate change"> climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrological%20modeling" title=" hydrological modeling"> hydrological modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=watershed" title=" watershed"> watershed</a> </p> <a href="https://publications.waset.org/abstracts/25736/variability-of-hydrological-modeling-of-the-blue-nile" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/25736.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">366</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4116</span> Identification of Watershed Landscape Character Types in Middle Yangtze River within Wuhan Metropolitan Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Huijie%20Wang">Huijie Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Bin%20Zhang"> Bin Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In China, the middle reaches of the Yangtze River are well-developed, boasting a wealth of different types of watershed landscape. In this regard, landscape character assessment (LCA) can serve as a basis for protection, management and planning of trans-regional watershed landscape types. For this study, we chose the middle reaches of the Yangtze River in Wuhan metropolitan area as our study site, wherein the water system consists of rich variety in landscape types. We analyzed trans-regional data to cluster and identify types of landscape characteristics at two levels. 55 basins were analyzed as variables with topography, land cover and river system features in order to identify the watershed landscape character types. For watershed landscape, drainage density and degree of curvature were specified as special variables to directly reflect the regional differences of river system features. Then, we used the principal component analysis (PCA) method and hierarchical clustering algorithm based on the geographic information system (GIS) and statistical products and services solution (SPSS) to obtain results for clusters of watershed landscape which were divided into 8 characteristic groups. These groups highlighted watershed landscape characteristics of different river systems as well as key landscape characteristics that can serve as a basis for targeted protection of watershed landscape characteristics, thus helping to rationally develop multi-value landscape resources and promote coordinated development of trans-regions. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=GIS" title="GIS">GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=hierarchical%20clustering" title=" hierarchical clustering"> hierarchical clustering</a>, <a href="https://publications.waset.org/abstracts/search?q=landscape%20character" title=" landscape character"> landscape character</a>, <a href="https://publications.waset.org/abstracts/search?q=landscape%20typology" title=" landscape typology"> landscape typology</a>, <a href="https://publications.waset.org/abstracts/search?q=principal%20component%20analysis" title=" principal component analysis"> principal component analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=watershed" title=" watershed"> watershed</a> </p> <a href="https://publications.waset.org/abstracts/105594/identification-of-watershed-landscape-character-types-in-middle-yangtze-river-within-wuhan-metropolitan-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/105594.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">228</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4115</span> Estimation of the Curve Number and Runoff Height Using the Arc CN-Runoff Tool in Sartang Ramon Watershed in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=L.Jowkar.%20M.Samiee">L.Jowkar.

In this study, the ArcCN-Runoff rain-runoff modeling tool was used to estimate the spatial variability of the rainfall-runoff relationship in Sartang Ramon in Jiroft watershed. In this study, the runoff was estimated from 6-hour rainfall. The results showed that based on hydrological soil group map, soils with hydrological groups A, B, C, and D covered 1, 2, 55, and 41% of the basin, respectively. Given that the majority of the area has a slope above 60 percent and results of soil hydrologic groups, one can conclude that Sartang Ramon Basin has a relatively high potential for producing runoff. The average runoff height for a 6-hour rainfall with a 2-year return period is 26.6 mm. The volume of runoff from the 2-year return period was calculated as the runoff height of each polygon multiplied by the area of the polygon, which is 137913486 m³ for the whole basin. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Arc%20CN-Run%20off" title="Arc CN-Run off">Arc CN-Run off</a>, <a href="https://publications.waset.org/abstracts/search?q=rain-runoff" title=" rain-runoff"> rain-runoff</a>, <a href="https://publications.waset.org/abstracts/search?q=return%20period" title=" return period"> return period</a>, <a href="https://publications.waset.org/abstracts/search?q=watershed" title=" watershed"> watershed</a> </p> <a href="https://publications.waset.org/abstracts/121495/estimation-of-the-curve-number-and-runoff-height-using-the-arc-cn-runoff-tool-in-sartang-ramon-watershed-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/121495.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">127</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4114</span> Progressive Watershed Management Approaches in Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20H.%20R.%20Sadeghi">S.

The issue, hence, is critical in developing countries like Iran where new technologies are rapidly luxuriated and unguardedly applied, resulting in unexpected outcomes. However, uncommon and comprehensive approaches are introduced to take all the different aspects involved into consideration. In the last decade, few approaches such as community-based, stakeholders-oriented, adaptive and ultimately integrated management, have emerged and are developing for efficient, Co-management or best management, economic and sustainable development and management of watershed resources in Iran. In the present paper, an attempt has been made to focus on state-of-the-art approaches for the management of watershed resources applied in Iran. The study has been then supported by reports of some case studies conducted throughout the country involving previously mentioned approaches. Scrutinizing results of the researches verified a progressive tendency of the managerial approaches in watershed management strategies leading to a general approaching balance situation. The approaches are firmly rooted in educational, research, executive, legal and policy-making sectors leading to some recuperation at different levels. However, there is a long way ahead to naturalize detrimental effects of unscientific, illegal and over exploitation of the watershed resources in Iran. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=comprehensive%20management" title="comprehensive management">comprehensive management</a>, <a href="https://publications.waset.org/abstracts/search?q=ecosystem%20balance" title=" ecosystem balance"> ecosystem balance</a>, <a href="https://publications.waset.org/abstracts/search?q=integrated%20watershed%20management" title=" integrated watershed management"> integrated watershed management</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20resources%20optimization" title=" land resources optimization"> land resources optimization</a> </p> <a href="https://publications.waset.org/abstracts/75597/progressive-watershed-management-approaches-in-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/75597.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">370</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4113</span> Integrated Watershed Management Practice in Chelchai Hyrcanian Forests in the North of Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mashad%20Maramaei">Mashad Maramaei</a>, <a href="https://publications.waset.org/abstracts/search?q=Behrooz%20Chogan"> Behrooz Chogan</a>, <a href="https://publications.waset.org/abstracts/search?q=Reza%20Ahmadi"> Reza Ahmadi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Human health and the health of his watershed are inseparable. This is because a watershed is an interconnected system of "land", "water", "air" and "life". Nowadays, most of the world's watersheds show symptoms of unhealthiness and require a prompt solution. It is believed that suitable solution is a participatory and Integrated Watershed Management (IWM). In recent decades the Hyrcanian forests in the north of Iran, which belongs to the end of the third geological era, are suffering from many environmental challenges such as land degradation, increasing trends of flood, drought and accelerated soil erosion. These challenges in the main forested area of the country impose many tangible and intangible damages and human losses. This is despite the fact that in the past decades, forestry programs, watershed management and other activities in the region have been implemented in a parallel and uncoordinated manner. Therefore, recently; the Natural Resources and Watershed Management Organization has resorted to the concept of IWM planning the Hyrcanian watersheds. The Chelchai watershed as mostly degraded watershed in the eastern part of the Hyrcanian forests has been selected as a pilot watershed for implementation of the IWM. It has a drainage area of 25680 hectares and receives an average annual precipitation of 650 mm. In this mountainous region, the average temperature is 17.3 degrees Celsius. About 34% of the watershed is under cultivation, 64% under forest cover, 2% under built up areas and etc. In this research, the effectiveness or ineffectiveness of the IWM model implementation of the Natural Resources and Watershed Management Organization has been evaluated based on questionnaire method and field studies. The results indicated that IWM activities in the study area should be reconsidered and revived. Based on this research and the lessons learned during five years' experience in the Chelchai watershed; authors believe that seven important tasks are necessary for socially acceptable and successful implementation of IWM projects. These are: 1) Establishment of Local Coordination Committee (LCC) at the watershed level 2) working for development of a IWM law among government organizations to organize watershed management and eliminate parallel and contradictory activities 3) More investment on education of local communities, especially women and children 4) Development of trust builder and pattern projects that showing best agricultural and livestock management activities at each of 26 villages 5) Assigning forest protection to local communities. 6) Capacity building of government stakeholders. 7) Helping in the marketing of watershed products. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=integrated%20watershed%20management" title="integrated watershed management">integrated watershed management</a>, <a href="https://publications.waset.org/abstracts/search?q=Chelchai" title=" Chelchai"> Chelchai</a>, <a href="https://publications.waset.org/abstracts/search?q=Hyrcanian%20forests" title=" Hyrcanian forests"> Hyrcanian forests</a>, <a href="https://publications.waset.org/abstracts/search?q=Iran" title=" Iran"> Iran</a> </p> <a href="https://publications.waset.org/abstracts/191691/integrated-watershed-management-practice-in-chelchai-hyrcanian-forests-in-the-north-of-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191691.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">21</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4112</span> Modeling and Mapping of Soil Erosion Risk Using Geographic Information Systems, Remote Sensing, and Deep Learning Algorithms: Case of the Oued Mikkes Watershed, Morocco</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=My%20Hachem%20Aouragh">My Hachem Aouragh</a>, <a href="https://publications.waset.org/abstracts/search?q=Hind%20Ragragui"> Hind Ragragui</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdellah%20El-Hmaidi"> Abdellah El-Hmaidi</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Essahlaoui"> Ali Essahlaoui</a>, <a href="https://publications.waset.org/abstracts/search?q=Abdelhadi%20El%20Ouali"> Abdelhadi El Ouali</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study investigates soil erosion susceptibility in the Oued Mikkes watershed, located in the Meknes-Fez region of northern Morocco, utilizing advanced techniques such as deep learning algorithms and remote sensing integrated within Geographic Information Systems (GIS). Spanning approximately 1,920 km², the watershed is characterized by a semi-arid Mediterranean climate with irregular rainfall and limited water resources. The waterways within the watershed, especially the Oued Mikkes, are vital for agricultural irrigation and potable water supply. The research assesses the extent of erosion risk upstream of the Sidi Chahed dam while developing a spatial model of soil loss. Several important factors, including topography, land use/land cover, and climate, were analyzed, with data on slope, NDVI, and rainfall erosivity processed using deep learning models (DLNN, CNN, RNN). The results demonstrated excellent predictive performance, with AUC values of 0.92, 0.90, and 0.88 for DLNN, CNN, and RNN, respectively. The resulting susceptibility maps provide critical insights for soil management and conservation strategies, identifying regions at high risk for erosion across 24% of the study area. The most high-risk areas are concentrated on steep slopes, particularly near the Ifrane district and the surrounding mountains, while low-risk areas are located in flatter regions with less rugged topography. The combined use of remote sensing and deep learning offers a powerful tool for accurate erosion risk assessment and resource management in the Mikkes watershed, highlighting the implications of soil erosion on dam siltation and operational efficiency. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=soil%20erosion" title="soil erosion">soil erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS" title=" GIS"> GIS</a>, <a href="https://publications.waset.org/abstracts/search?q=remote%20sensing" title=" remote sensing"> remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=deep%20learning" title=" deep learning"> deep learning</a>, <a href="https://publications.waset.org/abstracts/search?q=Mikkes%20Watershed" title=" Mikkes Watershed"> Mikkes Watershed</a>, <a href="https://publications.waset.org/abstracts/search?q=Morocco" title=" Morocco"> Morocco</a> </p> <a href="https://publications.waset.org/abstracts/193099/modeling-and-mapping-of-soil-erosion-risk-using-geographic-information-systems-remote-sensing-and-deep-learning-algorithms-case-of-the-oued-mikkes-watershed-morocco" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/193099.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">17</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4111</span> Modeling Sediment Yield of Jido River in the Rift Vally</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dawit%20%20Hailekrios%20Hailu">Dawit Hailekrios Hailu</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main objective of this study is to predict the sediment yield of the Jido River Watershed.

A modification of the Soil and Water Assessment Tool (called SWAT-Terrace or SWAT-T) explicitly aims to improve the simulation of the hydrological process of erosion from the terraces. SWAT-T simulates erosion from the terraces by separating terraces into three segments instead of evaluating the entire terrace. The objective of this work is to evaluate the terrace benefits on erosion from the Goodwater Creek Experimental Watershed (GCEW) at watershed and Hydrologic Response Unit (HRU) scales using SWAT-T. The HRU is the smallest spatial unit of the model, which lumps all similar land uses, soils, and slopes within a sub-basin. The SWAT-T model was parameterized for slope length, steepness and the empirical Universal Soil Erosion Equation support practice factor for three terrace segments. Data from 1993-2010 measured at the watershed outlet were used to evaluate the models for calibration and validation. Results of SWAT-T calibration showed good performance between measured and simulated erosion for the monthly time step, but poor performance for SWAT-T validation. This is probably because of large storms in spring 2002 that prevented planting, causing poorly simulated scheduling of actual field operations. To estimate terrace benefits on erosion, models were compared with and without terraces. Results showed that SWAT-T showed significant ~3% reduction in erosion (Pr <0.01) at the watershed scale and ~12% reduction in erosion at the HRU scale. Studies using the SWAT-T model indicated that the terraces have advantages to reduce erosion from terraced-agricultural watersheds. SWAT-T can be used in the evaluation of erosion to sustainably conserve the soil and water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Erosion" title="Erosion">Erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=Modeling" title=" Modeling"> Modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=Terraces" title=" Terraces"> Terraces</a>, <a href="https://publications.waset.org/abstracts/search?q=SWAT" title=" SWAT"> SWAT</a> </p> <a href="https://publications.waset.org/abstracts/104704/evaluating-the-terrace-benefits-of-erosion-in-a-terraced-agricultural-watershed-for-sustainable-soil-and-water-conservation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/104704.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">207</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4109</span> Effects of Watershed Erosion on Stream Channel Formation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Tiao%20Chang">Tiao Chang</a>, <a href="https://publications.waset.org/abstracts/search?q=Ivan%20Caballero"> Ivan Caballero</a>, <a href="https://publications.waset.org/abstracts/search?q=Hong%20Zhou"> Hong Zhou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Streams carry water and sediment naturally by maintaining channel dimensions, pattern, and profile over time. Watershed erosion as a natural process has occurred to contribute sediment to streams over time. The formation of channel dimensions is complex. This study is to relate quantifiable and consistent channel dimensions at the bankfull stage to the corresponding watershed erosion estimation by the Revised Universal Soil Loss Equation (RUSLE). Twelve sites of which drainage areas range from 7 to 100 square miles in the Hocking River Basin of Ohio were selected for the bankfull geometry determinations including width, depth, cross-section area, bed slope, and drainage area. The twelve sub-watersheds were chosen to obtain a good overall representation of the Hocking River Basin. It is of interest to determine how these bankfull channel dimensions are related to the soil erosion of corresponding sub-watersheds. Soil erosion is a natural process that has occurred in a watershed over time. The RUSLE was applied to estimate erosions of the twelve selected sub-watersheds where the bankfull geometry measurements were conducted. These quantified erosions of sub-watersheds are used to investigate correlations with bankfull channel dimensions including discharge, channel width, channel depth, cross-sectional area, and pebble distribution. It is found that drainage area, bankfull discharge and cross-sectional area correlates strongly with watershed erosion well. Furthermore, bankfull width and depth are moderately correlated with watershed erosion while the particle size, D50, of channel bed sediment is not well correlated with watershed erosion. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=watershed" title="watershed">watershed</a>, <a href="https://publications.waset.org/abstracts/search?q=stream" title=" stream"> stream</a>, <a href="https://publications.waset.org/abstracts/search?q=sediment" title=" sediment"> sediment</a>, <a href="https://publications.waset.org/abstracts/search?q=channel" title=" channel"> channel</a> </p> <a href="https://publications.waset.org/abstracts/70362/effects-of-watershed-erosion-on-stream-channel-formation" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/70362.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">287</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4108</span> Prioritization of Sub-Watersheds in Semi Arid Region: A Case Study of Shevgaon and Pathardi Tahsils in Maharashtra</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Dadasaheb%20R.%20Jawre">Dadasaheb R.

It shows the requirement of watershed to give a treatment for the green growth of the region and conservation of the sub-watersheds. There is a number of factors like topography of the region, climatic characteristics like rainfall and runoff, land-use land-cover, social factors which are related to the development of watershed for agricultural uses and domestic purposes in the region. The present research is throwing a focus on how morphometric parameters in association with GIS analysis will help in identifying the ranking of the sub-watersheds for further development which help of suggested watershed structures. Shevgaon and Pathardi tahsils are drought prone tahsils of Ahmednagar district in Maharashtra. These tahsils come under the semi-arid region. Sub-watershed prioritization is necessary for proper planning and management of natural resources for sustainable development of the study area. Less rainfall and increasing population pressure on the land as well as water resources lead to scarcity of the water in the region. Hence, researcher has selected Shevgaon and Pathardi tahsils for sub-watershed prioritization. There are seven sub-watersheds which selected for the present research paper. In the morphological analysis linear aspects, aerial aspects and relief aspects are considered for the prioritization. The largest sub-watershed is Erdha which is located at Karanji in Pathardi tahsil having an area of 145.06 km2 and smallest sub-watershed is Erandgaon which is located in Shevgaon tahsil having an area of 40.143 km2. For all seven sub-watersheds, seven morphometric parameters were considered for calculating the compound parameter values. Finally, compound parameter values are grouped into three groups such as, high priority (below 4.0), moderate priority (4.0 to 5.0) and low priority (above 5.0) according to the compound value Erandgaon, Chapadgaon and Tarak sub-watersheds comes under high priority group, Erdha and Domeshwar sub-watersheds come under moderate priority group and Chandani and Kasichi sub-watershed come under low priority group. Both the tahsils falls in drought prone area, after getting the watershed structure overall development of the region will take place. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=sub-watersheds" title="sub-watersheds">sub-watersheds</a>, <a href="https://publications.waset.org/abstracts/search?q=GIS%20and%20remote%20sensing" title=" GIS and remote sensing"> GIS and remote sensing</a>, <a href="https://publications.waset.org/abstracts/search?q=morphometric%20analysis" title=" morphometric analysis"> morphometric analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=compound%20parameter%20value" title=" compound parameter value"> compound parameter value</a>, <a href="https://publications.waset.org/abstracts/search?q=prioritization" title=" prioritization"> prioritization</a> </p> <a href="https://publications.waset.org/abstracts/150223/prioritization-of-sub-watersheds-in-semi-arid-region-a-case-study-of-shevgaon-and-pathardi-tahsils-in-maharashtra" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150223.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">153</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4107</span> Land Suitability Analysis for Rice Production in a Typical Watershed of Southwestern Nigeria: A Sustainability Pathway</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oluwagbenga%20O.%20Isaac%20Orimoogunje">Oluwagbenga O.

By having students study and assess the watershed dynamics of a local stream, they will better understand how human activities affect this valuable resource. It is important that students gain tangible skills that will help them to have an understanding of water quality analysis and the importance of preserving our Earth's water systems. Having students participate in real world practices is the optimal learning environment and can offer students a genuine learning experience, by cultivating a knowledge of place, while promoting education for sustainability. Additionally, developing a watershed science course for high school students will give them a hands-on approach to studying science; which is both beneficial and more satisfying to students. When students conduct their own research, collect and analyze data, they will be intimately involved in addressing water quality issues and solving critical water quality problems. By providing students with activities that take place outside the confines of the indoor classroom, you give them the opportunity to gain an appreciation of the natural world. Placed-based learning provides students with problem-solving skills in everyday situations while enhancing skills of inquiry. An overview of a place-based watershed science course and its impact on student learning will be presented. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=education%20for%20sustainability" title="education for sustainability">education for sustainability</a>, <a href="https://publications.waset.org/abstracts/search?q=place-based%20learning" title=" place-based learning"> place-based learning</a>, <a href="https://publications.waset.org/abstracts/search?q=watershed%20science" title=" watershed science"> watershed science</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title=" water quality"> water quality</a> </p> <a href="https://publications.waset.org/abstracts/84182/education-for-sustainability-implementing-a-place-based-watershed-science-course-for-high-school-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/84182.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">154</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4105</span> Prediction of Saturated Hydraulic Conductivity Dynamics in an Iowan Agriculture Watershed</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Elhakeem">Mohamed Elhakeem</a>, <a href="https://publications.waset.org/abstracts/search?q=A.%20N.%20Thanos%20Papanicolaou"> A.

The modelling framework integrated selected pedotransfer functions and watershed models with geospatial tools. A number of pedotransfer functions and agricultural watershed models were examined to select the appropriate models that represent the study site conditions. Models selection was based on statistical measures of the models’ errors compared to the KSAT field measurements conducted in the CCW under different soil, climate and land use conditions. The study has shown that the predictions of the combined pedotransfer function of Rosetta and the Water Erosion Prediction Project (WEPP) provided the best agreement to the measured KSAT values in the CCW compared to the other tested models. Therefore, Rosetta and WEPP were integrated with the Geographic Information System (GIS) tools for visualization of the data in forms of geospatial maps and prediction of KSAT variability in CCW due to the seasonal changes in climate and land use activities. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=saturated%20hydraulic%20conductivity" title="saturated hydraulic conductivity">saturated hydraulic conductivity</a>, <a href="https://publications.waset.org/abstracts/search?q=pedotransfer%20functions" title=" pedotransfer functions"> pedotransfer functions</a>, <a href="https://publications.waset.org/abstracts/search?q=watershed%20models" title=" watershed models"> watershed models</a>, <a href="https://publications.waset.org/abstracts/search?q=geospatial%20tools" title=" geospatial tools"> geospatial tools</a> </p> <a href="https://publications.waset.org/abstracts/5877/prediction-of-saturated-hydraulic-conductivity-dynamics-in-an-iowan-agriculture-watershed" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/5877.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">260</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4104</span> Potential of Landslides Based On Maximum Monthly Rainfall in Sumber Sari Village Watershed Tirtomoyo Wonogiri Indonesia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Heny%20Pratiwi">Heny Pratiwi</a>, <a href="https://publications.waset.org/abstracts/search?q=Niken%20Silmi%20Surjandari"> Niken Silmi Surjandari</a>, <a href="https://publications.waset.org/abstracts/search?q=Noegroho%20Djarwanti"> Noegroho Djarwanti</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study was conducted to determine the potential for landslides as a result of monthly rainfall in a watershed.

This can be achieved through the research. Several studies have investigated both surface water and groundwater in Beterou catchment. However, there are few published papers on the application of the SWAT modeling in Beterou catchment. The objective of this study was to evaluate the performance of SWAT to simulate the water balance within the watershed. The inputs data consist of digital elevation model, land use maps, soil map, climatic data and discharge records. The model was calibrated and validated using the Sequential Uncertainty Fitting (SUFI2) approach. The calibrated started from 1989 to 2006 with four years warming up period (1985-1988); and validation was from 2007 to 2020. The goodness of the model was assessed using five indices, i.e., Nash–Sutcliffe efficiency (NSE), the ratio of the root means square error to the standard deviation of measured data (RSR), percent bias (PBIAS), the coefficient of determination (R²), and Kling Gupta efficiency (KGE). Results showed that SWAT model successfully simulated river flow in Beterou catchment with NSE = 0.79, R2 = 0.80 and KGE= 0.83 for the calibration process against validation process that provides NSE = 0.78, R2 = 0.78 and KGE= 0.85 using site-based streamflow data. The relative error (PBIAS) ranges from -12.2% to 3.1%. The parameters runoff curve number (CN2), Moist Bulk Density (SOL_BD), Base Flow Alpha Factor (ALPHA_BF), and the available water capacity of the soil layer (SOL_AWC) were the most sensitive parameter. The study provides further research with uncertainty analysis and recommendations for model improvement and provision of an efficient means to improve rainfall and discharges measurement data. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=watershed" title="watershed">watershed</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20balance" title=" water balance"> water balance</a>, <a href="https://publications.waset.org/abstracts/search?q=SWAT%20modeling" title=" SWAT modeling"> SWAT modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=Beterou" title=" Beterou"> Beterou</a> </p> <a href="https://publications.waset.org/abstracts/177705/estimating-water-balance-at-beterou-watershed-benin-using-soil-and-water-assessment-tool-swat-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/177705.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">55</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4102</span> Hydrological Modeling of Watersheds Using the Only Corresponding Competitor Method: The Case of M’Zab Basin, South East Algeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Oulad%20Naoui%20Noureddine">Oulad Naoui Noureddine</a>, <a href="https://publications.waset.org/abstracts/search?q=Cherif%20ELAmine"> Cherif ELAmine</a>, <a href="https://publications.waset.org/abstracts/search?q=Djehiche%20Abdelkader"> Djehiche Abdelkader</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water resources management includes several disciplines; the modeling of rainfall-runoff relationship is the most important discipline to prevent natural risks.

This study quantifies the parametric uncertainty involved in simulation of stream flow using Soil and Water Assessment Tool (SWAT), a watershed scale model and Radial Basis Neural Network (RBNN), an artificial neural network model. Both the models were calibrated and validated based on measured stream flow and quantification of the uncertainty in SWAT model output was assessed using ‘‘Sequential Uncertainty Fitting Algorithm’’ (SUFI-2). Though both the model predicted satisfactorily, but RBNN model performed better than SWAT with R2 and NSE values of 0.92 and 0.92 during training, and 0.71 and 0.70 during validation period, respectively. Comparison of the results of the two models also indicates a wider prediction interval for the results of the SWAT model. The values of P-factor related to each model shows that the percentage of observed stream flow values bracketed by the 95PPU in the RBNN model as 91% is higher than the P-factor in SWAT as 87%. In other words the RBNN model estimates the stream flow values more accurately and with less uncertainty. It could be stated that RBNN model based on simple input could be used for estimation of monthly stream flow, missing data, and testing the accuracy and performance of other models. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=SWAT" title="SWAT">SWAT</a>, <a href="https://publications.waset.org/abstracts/search?q=RBNN" title=" RBNN"> RBNN</a>, <a href="https://publications.waset.org/abstracts/search?q=SUFI%202" title=" SUFI 2"> SUFI 2</a>, <a href="https://publications.waset.org/abstracts/search?q=bootstrap%20technique" title=" bootstrap technique"> bootstrap technique</a>, <a href="https://publications.waset.org/abstracts/search?q=stream%20flow" title=" stream flow"> stream flow</a>, <a href="https://publications.waset.org/abstracts/search?q=simulation" title=" simulation"> simulation</a> </p> <a href="https://publications.waset.org/abstracts/21788/modeling-stream-flow-with-prediction-uncertainty-by-using-swat-hydrologic-and-rbnn-neural-network-models-for-agricultural-watershed-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21788.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">370</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4100</span> Determination of Soil Loss by Erosion in Different Land Covers Categories and Slope Classes in Bovilla Watershed, Tirana, Albania</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Valmir%20Baloshi">Valmir Baloshi</a>, <a href="https://publications.waset.org/abstracts/search?q=Fran%20Gjoka"> Fran Gjoka</a>, <a href="https://publications.waset.org/abstracts/search?q=Nehat%20%C3%87ollaku"> Nehat Çollaku</a>, <a href="https://publications.waset.org/abstracts/search?q=Elvin%20Toromani"> Elvin Toromani</a> </p> <p class="card-text"><strong>Abstract:</strong></p> As a sediment production mechanism, soil erosion is the main environmental threat to the Bovilla watershed, including the decline of water quality of the Bovilla reservoir that provides drinking water to Tirana city (the capital of Albania). Therefore, an experiment with 25 erosion plots for soil erosion monitoring has been set up since June 2017. The aim was to determine the soil loss on plot and watershed scale in Bovilla watershed (Tirana region) for implementation of soil and water protection measures or payments for ecosystem services (PES) programs. The results of erosion monitoring for the period June 2017 - May 2018 showed that the highest values of surface runoff were noted in bare land of 38829.91 liters on slope of 74% and the lowest values in forest land of 12840.6 liters on slope of 64% while the highest values of soil loss were found in bare land of 595.15 t/ha on slope of 62% and lowest values in forest land of 18.99 t/ha on slope of 64%. These values are much higher than the average rate of soil loss in the European Union (2.46 ton/ha/year). In the same sloping class, the soil loss was reduced from orchard or bare land to the forest land, and in the same category of land use, the soil loss increased with increasing land slope. It is necessary to conduct chemical analyses of sediments to determine the amount of chemical elements leached out of the soil and end up in the reservoir of Bovilla. It is concluded that PES programs should be implemented for rehabilitation of sub-watersheds Ranxe, Vilez and Zall-Bastar of the Bovilla watershed with valuable conservation practices. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=ANOVA" title="ANOVA">ANOVA</a>, <a href="https://publications.waset.org/abstracts/search?q=Bovilla" title=" Bovilla"> Bovilla</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20cover" title=" land cover"> land cover</a>, <a href="https://publications.waset.org/abstracts/search?q=slope" title=" slope"> slope</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20loss" title=" soil loss"> soil loss</a>, <a href="https://publications.waset.org/abstracts/search?q=watershed%20management" title=" watershed management"> watershed management</a> </p> <a href="https://publications.waset.org/abstracts/102135/determination-of-soil-loss-by-erosion-in-different-land-covers-categories-and-slope-classes-in-bovilla-watershed-tirana-albania" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/102135.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">161</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4099</span> Investigating the Impacts of Climate Change on Soil Erosion: A Case Study of Kasilian Watershed, Northern Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Zare">Mohammad Zare</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahbubeh%20Sheikh"> Mahbubeh Sheikh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Many of the impact of climate change will material through change in soil erosion which were rarely addressed in Iran.

The potential for climate change to increase soil loss rate, soil erosion in future periods was established, whereas considerable decreases in erosion are projected when land use is increased from baseline periods. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kasilian%20watershed" title="Kasilian watershed">Kasilian watershed</a>, <a href="https://publications.waset.org/abstracts/search?q=climatic%20change" title=" climatic change"> climatic change</a>, <a href="https://publications.waset.org/abstracts/search?q=soil%20erosion" title=" soil erosion"> soil erosion</a>, <a href="https://publications.waset.org/abstracts/search?q=LARS-WG5%20Model" title=" LARS-WG5 Model"> LARS-WG5 Model</a>, <a href="https://publications.waset.org/abstracts/search?q=RUSLE" title=" RUSLE"> RUSLE</a> </p> <a href="https://publications.waset.org/abstracts/14384/investigating-the-impacts-of-climate-change-on-soil-erosion-a-case-study-of-kasilian-watershed-northern-iran" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/14384.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">506</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4098</span> Hydro-Climatological, Geological, Hydrogeological and Geochemical Study of the Coastal Aquifer System of Chiba Watershed (Cape Bon Peninsula)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Khawla%20Askri">Khawla Askri</a>, <a href="https://publications.waset.org/abstracts/search?q=Mohamed%20Haythem%20Msaddek"> Mohamed Haythem Msaddek</a>, <a href="https://publications.waset.org/abstracts/search?q=AbdelAziz%20Sebei"> AbdelAziz Sebei</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Climate change combined with the increase in anthropogenic activities will affect coastal groundwater systems around the world and, more particularly, the Cap Bon region in the North East of Tunisia. This study aims to study the impact of climate change and human stress on the salinization and quantification of groundwater in the Wadi Chiba watershed. In this regard, a hydro-climatological study and a hydrogeological study were carried out based on the characterization of the aquifer system of the eastern coast at the level of the watershed of Wadi Chiba in order to seek to identify, first of all, the degradation of the state of the aquifer on the quantitative level by the study of the piezometric and its evolution over time. Secondly, we sought to identify the degradation of the state of the aquifer qualitatively by using the geochemical method, in particular the major elements, to assess the mineralization of the aquifer water and understand its hydrogeochemical functioning. The study of the Na + / Cl- and Ca2 + / Mg2 + chemical relationships confirmed the presence of a marine intrusion downstream of the Wadi Chiba watershed northeast of Cap-Bon accompanied by a piezometric depression. For this purpose, we proceeded to: 1) Mapping of both piezometric data and salinity. 2) The interpretation of the mapping results. 3)Identification of the origin of the localized deterioration in the quality of the aquifer water. Finally, the analysis of the results showed that the scarcity of water is already forcing human actions in the Chiba watershed due to the irrigation of agricultural lands and the overexploitation of the water table in the study area. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=climate%20change" title="climate change">climate change</a>, <a href="https://publications.waset.org/abstracts/search?q=human%20activities" title=" human activities"> human activities</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20table" title=" water table"> water table</a>, <a href="https://publications.waset.org/abstracts/search?q=Wadi%20Chiba%20watershed" title=" Wadi Chiba watershed"> Wadi Chiba watershed</a>, <a href="https://publications.waset.org/abstracts/search?q=piezometric%20depression" title=" piezometric depression"> piezometric depression</a>, <a href="https://publications.waset.org/abstracts/search?q=marine%20intrusion" title=" marine intrusion"> marine intrusion</a> </p> <a href="https://publications.waset.org/abstracts/163279/hydro-climatological-geological-hydrogeological-and-geochemical-study-of-the-coastal-aquifer-system-of-chiba-watershed-cape-bon-peninsula" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/163279.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">92</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4097</span> Evaluation of Water Management Options to Improve the Crop Yield and Water Productivity for Semi-Arid Watershed in Southern India Using AquaCrop Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=V.%20S.%20Manivasagam">V.

Progress in understanding the crop growth response during water stress period through crop modeling approach provides an opportunity for improving and sustaining the future agriculture water use efficiency. An attempt has been made to evaluate the potential use of crop modeling approach for assessing the minimal supplementary irrigation requirement for crop growth during water limited condition and its practical significance in sustainable improvement of crop yield and water productivity. Among the numerous crop models, water driven-AquaCrop model has been chosen for the present study considering the modeling approach and water stress impact on yield simulation. The study has been evaluated in rainfed maize grown area of semi-arid Shanmuganadi watershed (a tributary of the Cauvery river system) located in southern India during the rabi cropping season (October-February). In addition to actual rainfed maize growth simulation, irrigated maize scenarios were simulated for assessing the supplementary irrigation requirement during water shortage condition for the period 2012-2015. The simulation results for rainfed maize have shown that the average maize yield of 0.5-2 t ha-1 was observed during deficit monsoon season (<350 mm) whereas 5.3 t ha-1 was noticed during sufficient monsoonal period (>350 mm). Scenario results for irrigated maize simulation during deficit monsoonal period has revealed that 150-200 mm of supplementary irrigation has ensured the 5.8 t ha-1 of irrigated maize yield. Thus, study results clearly portrayed that minimal application of supplementary irrigation during the critical growth period along with the deficit rainfall has increased the crop water productivity from 1.07 to 2.59 kg m-3 for major soil types. Overall, AquaCrop is found to be very effective for the sustainable irrigation assessment considering the model simplicity and minimal inputs requirement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=AquaCrop" title="AquaCrop">AquaCrop</a>, <a href="https://publications.waset.org/abstracts/search?q=crop%20modeling" title=" crop modeling"> crop modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=rainfed%20maize" title=" rainfed maize"> rainfed maize</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20stress" title=" water stress"> water stress</a> </p> <a href="https://publications.waset.org/abstracts/54765/evaluation-of-water-management-options-to-improve-the-crop-yield-and-water-productivity-for-semi-arid-watershed-in-southern-india-using-aquacrop-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/54765.pdf" target="_blank" class="btn btn-primary btn-sm">PDF</a> <span class="bg-info text-light px-1 py-1 float-right rounded"> Downloads <span class="badge badge-light">266</span> </span> </div> </div> <div class="card paper-listing mb-3 mt-3"> <h5 class="card-header" style="font-size:.9rem"><span class="badge badge-info">4096</span> Image Analysis for Obturator Foramen Based on Marker-controlled Watershed Segmentation and Zernike Moments</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Seda%20Sahin">Seda Sahin</a>, <a href="https://publications.waset.org/abstracts/search?q=Emin%20Akata"> Emin Akata</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Obturator foramen is a specific structure in pelvic bone images and recognition of it is a new concept in medical image processing. Moreover, segmentation of bone structures such as obturator foramen plays an essential role for clinical research in orthopedics. In this paper, we present a novel method to analyze the similarity between the substructures of the imaged region and a hand drawn template, on hip radiographs to detect obturator foramen accurately with integrated usage of Marker-controlled Watershed segmentation and Zernike moment feature descriptor. Marker-controlled Watershed segmentation is applied to seperate obturator foramen from the background effectively. Zernike moment feature descriptor is used to provide matching between binary template image and the segmented binary image for obturator foramens for final extraction. The proposed method is tested on randomly selected 100 hip radiographs. The experimental results represent that our method is able to segment obturator foramens with % 96 accuracy. <p class="card-text"><strong>Keywords:</strong> <a
