Initial phases relate to field programs and desktop studies intended to build the data and knowledge base, including the design of water management infrastructure and development during these initial phases. Such a model is essential to demonstrate that the water management plan (WMP) will provide adequate water for the mine operations and sufficient capacity for anticipated flows and volumes, and minimize environmental impacts on the receiving environment. The water and mass balance model must cover the whole mine life cycle, from the start of mine development to a date sufficiently far in the future where the reclaimed landscape is considered self- sustaining following complete closure of the mine (i.e., post- closure). The model simulates the movement of water within the components of the water management infrastructure and project operating areas, and calculates chemical loadings to each mine component. At Erdenet Mining company an initial water balance model reflecting the tailings dam, groundwater seepage and mine process water was developed in collaboration with Dr. Scott Kenner (visiting Fulbright scholar). From this preliminary study the following recommendations were made: 1. Develop a detailed groundwater model to simulate seepage from the tailings dam, 2. Establish an evaporation pan for improving evapotranspiration estimates, and 3. Measure changes in storage of water within the tailings dam and other water storage components within the mine processing. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=evapotranspiration" title="evapotranspiration ">evapotranspiration </a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring%20program" title=" monitoring program"> monitoring program</a>, <a href="https://publications.waset.org/abstracts/search?q=Erdenet%20mining" title=" Erdenet mining"> Erdenet mining</a>, <a href="https://publications.waset.org/abstracts/search?q=tailings%20dam" title=" tailings dam"> tailings dam</a> </p> <a href="https://publications.waset.org/abstracts/20522/water-management-of-erdenet-mining-company" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/20522.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">477</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">11571</span> Groundwater Monitoring Using a Community: Science Approach</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Shobha%20Kumari%20Yadav">Shobha Kumari Yadav</a>, <a href="https://publications.waset.org/abstracts/search?q=Yubaraj%20Satyal"> Yubaraj Satyal</a>, <a href="https://publications.waset.org/abstracts/search?q=Ajaya%20Dixit"> Ajaya Dixit</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In addressing groundwater depletion, it is important to develop evidence base so to be used in assessing the state of its degradation. Groundwater data is limited compared to meteorological data, which impedes the groundwater use and management plan. Monitoring of groundwater levels provides information base to assess the condition of aquifers, their responses to water extraction, land-use change, and climatic variability. It is important to maintain a network of spatially distributed, long-term monitoring wells to support groundwater management plan. Monitoring involving local community is a cost effective approach that generates real time data to effectively manage groundwater use. This paper presents the relationship between rainfall and spring flow, which are the main source of freshwater for drinking, household consumptions and agriculture in hills of Nepal. The supply and withdrawal of water from springs depends upon local hydrology and the meteorological characteristics- such as rainfall, evapotranspiration and interflow. The study offers evidence of the use of scientific method and community based initiative for managing groundwater and springshed. The approach presents a method to replicate similar initiative in other parts of the country for maintaining integrity of springs. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=citizen%20science" title="citizen science">citizen science</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20resource%20management" title=" water resource management"> water resource management</a>, <a href="https://publications.waset.org/abstracts/search?q=Nepal" title=" Nepal"> Nepal</a> </p> <a href="https://publications.waset.org/abstracts/45352/groundwater-monitoring-using-a-community-science-approach" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45352.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">202</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">11570</span> Groundwater Treatment of Thailand's Mae Moh Lignite Mine </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=A.%20Laksanayothin">A.

Ariyawong</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Mae Moh Lignite Mine is the largest open-pit mine in Thailand. The mine serves coal to the power plant about 16 million tons per year. This amount of coal can produce electricity accounting for about 10% of Nation’s electric power generation. The mining area of Mae Moh Mine is about 28 km2. At present, the deepest area of the pit is about 280 m from ground level (+40 m. MSL) and in the future the depth of the pit can reach 520 m from ground level (-200 m.MSL). As the size of the pit is quite large, the stability of the pit is seriously important. Furthermore, the preliminary drilling and extended drilling in year 1989-1996 had found high pressure aquifer under the pit. As a result, the pressure of the underground water has to be released in order to control mine pit stability. The study by the consulting experts later found that 3-5 million m3 per year of the underground water is needed to be de-watered for the safety of mining. However, the quality of this discharged water should meet the standard. Therefore, the ground water treatment facility has been implemented, aiming to reduce the amount of naturally contaminated Arsenic (As) in discharged water lower than the standard limit of 10 ppb. The treatment system consists of coagulation and filtration process. The main components include rapid mixing tanks, slow mixing tanks, sedimentation tank, thickener tank and sludge drying bed. The treatment process uses 40% FeCl3 as a coagulant. The FeCl3 will adsorb with As(V), forming floc particles and separating from the water as precipitate. After that, the sludge is dried in the sand bed and then be disposed in the secured land fill. Since 2011, the treatment plant of 12,000 m3/day has been efficiently operated. The average removal efficiency of the process is about 95%. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=arsenic" title="arsenic">arsenic</a>, <a href="https://publications.waset.org/abstracts/search?q=coagulant" title=" coagulant"> coagulant</a>, <a href="https://publications.waset.org/abstracts/search?q=ferric%20chloride" title=" ferric chloride"> ferric chloride</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=lignite" title=" lignite"> lignite</a>, <a href="https://publications.waset.org/abstracts/search?q=coal%20mine" title=" coal mine "> coal mine </a> </p> <a href="https://publications.waset.org/abstracts/21429/groundwater-treatment-of-thailands-mae-moh-lignite-mine" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21429.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">310</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">11569</span> Geochemistry of Natural Radionuclides Associated with Acid Mine Drainage (AMD) in a Coal Mining Area in Southern Brazil</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Juliana%20A.%20Galhardi">Juliana A.

Bonotto</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Coal is an important non-renewable energy source of and can be associated with radioactive elements. In Figueira city, Paraná state, Brazil, it was recorded high uranium activity near the coal mine that supplies a local thermoelectric power plant. In this context, the radon activity (Rn-222, produced by the Ra-226 decay in the U-238 natural series) was evaluated in groundwater, river water and effluents produced from the acid mine drainage in the coal reject dumps. The samples were collected in August 2013 and in February 2014 and analyzed at LABIDRO (Laboratory of Isotope and Hydrochemistry), UNESP, Rio Claro city, Brazil, using an alpha spectrometer (AlphaGuard) adjusted to evaluate the mean radon activity concentration in five cycles of 10 minutes. No radon activity concentration above 100 Bq.L-1, which was a previous critic value established by the World Health Organization. The average radon activity concentration in groundwater was higher than in surface water and in effluent samples, possibly due to the accumulation of uranium and radium in the aquifer layers that favors the radon trapping. The lower value in the river waters can indicate dilution and the intermediate value in the effluents may indicate radon absorption in the coal particles of the reject dumps. The results also indicate that the radon activities in the effluents increase with the sample acidification, possibly due to the higher radium leaching and the subsequent radon transport to the drainage flow. The water samples of Laranjinha River and Ribeirão das Pedras stream, which, respectively, supply Figueira city and receive the mining effluent, exhibited higher pH values upstream the mine, reflecting the acid mine drainage discharge. The radionuclides transport indicates the importance of monitoring their activity concentration in natural waters due to the risks that the radioactivity can represent to human health. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=radon" title="radon">radon</a>, <a href="https://publications.waset.org/abstracts/search?q=radium" title=" radium"> radium</a>, <a href="https://publications.waset.org/abstracts/search?q=acid%20mine%20drainage" title=" acid mine drainage"> acid mine drainage</a>, <a href="https://publications.waset.org/abstracts/search?q=coal" title=" coal"> coal</a> </p> <a href="https://publications.waset.org/abstracts/29263/geochemistry-of-natural-radionuclides-associated-with-acid-mine-drainage-amd-in-a-coal-mining-area-in-southern-brazil" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29263.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">432</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">11568</span> Water Quality at a Ventilated Improved Pit Latrine Sludge Entrenchment Site</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Babatunde%20Femi%20Bakare">Babatunde Femi Bakare </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundwater quality was evaluated at a site for three years after the site was used for entrenchment of Ventilated Improved Pit (VIP) latrine sludge. Analysis performed on the soil characteristics at the entrenchment site indicated that, the soils at the entrenchment site are predominantly sandy. Depth of the water table at the entrenchment site was found to be approximately five meters. Five monitoring boreholes were dug along the perimeter of the sludge trenches and water samples taken from these monitoring boreholes were analyzed for pH, conductivity, sodium ions, chloride ions, phosphate, nitrate, ammonia, and bacteriological analysis. The results obtained from the analysis conducted were compared with the South African Bureau of Standards for drinking water and it was found that the parameters analyzed falls below the specified range. The data obtained from this study indicate that, given the relatively high sludge loading rates, poor soil quality, and the duration of the groundwater quality monitoring, it is unlikely that contamination of groundwater at the entrenchment site will be a major concern. However, caution is advised in extrapolating these results to other locations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=boreholes" title="boreholes">boreholes</a>, <a href="https://publications.waset.org/abstracts/search?q=contamination" title=" contamination"> contamination</a>, <a href="https://publications.waset.org/abstracts/search?q=entrenchment" title=" entrenchment"> entrenchment</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20quality" title=" groundwater quality"> groundwater quality</a>, <a href="https://publications.waset.org/abstracts/search?q=VIP%20latrines" title=" VIP latrines"> VIP latrines</a> </p> <a href="https://publications.waset.org/abstracts/3677/water-quality-at-a-ventilated-improved-pit-latrine-sludge-entrenchment-site" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3677.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">410</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">11567</span> Application of Remote Sensing Technique on the Monitoring of Mine Eco-Environment</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Haidong%20Li">Haidong Li</a>, <a href="https://publications.waset.org/abstracts/search?q=Weishou%20Shen"> Weishou Shen</a>, <a href="https://publications.waset.org/abstracts/search?q=Guoping%20Lv"> Guoping Lv</a>, <a href="https://publications.waset.org/abstracts/search?q=Tao%20Wang"> Tao Wang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aiming to overcome the limitation of the application of traditional remote sensing (RS) technique in the mine eco-environmental monitoring, in this paper, we first classified the eco-environmental damages caused by mining activities and then introduced the principle, classification and characteristics of the Light Detection and Ranging (LiDAR) technique. The potentiality of LiDAR technique in the mine eco-environmental monitoring was analyzed, particularly in extracting vertical structure parameters of vegetation, through comparing the feasibility and applicability of traditional RS method and LiDAR technique in monitoring different types of indicators. The application situation of LiDAR technique in extracting typical mine indicators, such as land destruction in mining areas, damage of ecological integrity and natural soil erosion. The result showed that the LiDAR technique has the ability to monitor most of the mine eco-environmental indicators, and exhibited higher accuracy comparing with traditional RS technique, specifically speaking, the applicability of LiDAR technique on each indicator depends on the accuracy requirement of mine eco-environmental monitoring. In the item of large mine, LiDAR three-dimensional point cloud data not only could be used as the complementary data source of optical RS, Airborne/Satellite LiDAR could also fulfill the demand of extracting vertical structure parameters of vegetation in large areas. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=LiDAR" title="LiDAR">LiDAR</a>, <a href="https://publications.waset.org/abstracts/search?q=mine" title=" mine"> mine</a>, <a href="https://publications.waset.org/abstracts/search?q=ecological%20damage" title=" ecological damage"> ecological damage</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=traditional%20remote%20sensing%20technique" title=" traditional remote sensing technique"> traditional remote sensing technique</a> </p> <a href="https://publications.waset.org/abstracts/65821/application-of-remote-sensing-technique-on-the-monitoring-of-mine-eco-environment" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/65821.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">397</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">11566</span> Monitoring of Hydrological Parameters in the Alexandra Jukskei Catchment in South Africa</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Vhuhwavho%20Gadisi">Vhuhwavho Gadisi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebecca%20Alowo"> Rebecca Alowo</a>, <a href="https://publications.waset.org/abstracts/search?q=German%20Nkhonjera"> German Nkhonjera</a> </p> <p class="card-text"><strong>Abstract:</strong></p> It has been noted that technical programming for handling groundwater resources is not accessible. The lack of these systems hinders groundwater management processes necessary for decision-making through monitoring and evaluation regarding the Jukskei River of the Crocodile River (West) Basin in Johannesburg, South Africa. Several challenges have been identified in South Africa's Jukskei Catchment concerning groundwater management. Some of those challenges will include the following: Gaps in data records; there is a need for training and equipping of monitoring staff; formal accreditation of monitoring capacities and equipment; there is no access to regulation terms (e.g., meters). Taking into consideration necessities and human requirements as per typical densities in various regions of South Africa, there is a need to construct several groundwater level monitoring stations in a particular segment; the available raw data on groundwater level should be converted into consumable products for example, short reports on delicate areas (e.g., Dolomite compartments, wetlands, aquifers, and sole source) and considering the increasing civil unrest there has been vandalism and theft of groundwater monitoring infrastructure. GIS was employed at the catchment level to plot the relationship between those identified groundwater parameters in the catchment area and the identified borehole. GIS-based maps were designed for groundwater monitoring to be pretested on one borehole in the Jukskei catchment. This data will be used to establish changes in the borehole compared to changes in the catchment area according to identified parameters. <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=monitoring" title=" monitoring"> monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=Jukskei" title=" Jukskei"> Jukskei</a>, <a href="https://publications.waset.org/abstracts/search?q=catchment" title=" catchment"> catchment</a> </p> <a href="https://publications.waset.org/abstracts/165746/monitoring-of-hydrological-parameters-in-the-alexandra-jukskei-catchment-in-south-africa" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/165746.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">94</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">11565</span> Critical Evaluation of Groundwater Monitoring Networks for Machine Learning Applications</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Pedro%20Martinez-Santos">Pedro Martinez-Santos</a>, <a href="https://publications.waset.org/abstracts/search?q=V%C3%ADctor%20G%C3%B3mez-Escalonilla"> Víctor Gómez-Escalonilla</a>, <a href="https://publications.waset.org/abstracts/search?q=Silvia%20D%C3%ADaz-Alcaide"> Silvia Díaz-Alcaide</a>, <a href="https://publications.waset.org/abstracts/search?q=Esperanza%20Montero"> Esperanza Montero</a>, <a href="https://publications.waset.org/abstracts/search?q=Miguel%20Mart%C3%ADn-Loeches"> Miguel Martín-Loeches</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundwater monitoring networks are critical in evaluating the vulnerability of groundwater resources to depletion and contamination, both in space and time. Groundwater monitoring networks typically grow over decades, often in organic fashion, with relatively little overall planning. The groundwater monitoring networks in the Madrid area, Spain, were reviewed for the purpose of identifying gaps and opportunities for improvement. Spatial analysis reveals the presence of various monitoring networks belonging to different institutions, with several hundred observation wells in an area of approximately 4000 km2. This represents several thousand individual data entries, some going back to the early 1970s. Major issues included overlap between the networks, unknown screen depth/vertical distribution for many observation boreholes, uneven time series, uneven monitored species, and potentially suboptimal locations. Results also reveal there is sufficient information to carry out a spatial and temporal analysis of groundwater vulnerability based on machine learning applications. These can contribute to improve the overall planning of monitoring networks’ expansion into the future. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=groundwater%20monitoring" title="groundwater monitoring">groundwater monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=observation%20networks" title=" observation networks"> observation networks</a>, <a href="https://publications.waset.org/abstracts/search?q=machine%20learning" title=" machine learning"> machine learning</a>, <a href="https://publications.waset.org/abstracts/search?q=madrid" title=" madrid"> madrid</a> </p> <a href="https://publications.waset.org/abstracts/173455/critical-evaluation-of-groundwater-monitoring-networks-for-machine-learning-applications" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/173455.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">78</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">11564</span> A Novel Approach for the Analysis of Ground Water Quality by Using Classification Rules and Water Quality Index</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kamakshaiah%20Kolli">Kamakshaiah Kolli</a>, <a href="https://publications.waset.org/abstracts/search?q=R.%20Seshadri"> R.

Only a tiny fraction of the planet's abundant water is available to us as fresh water. Assessment of water quality has always been paramount in the field of environmental quality management. It is the foundation for health, hygiene, progress and prosperity. With ever increasing pressure of human population, there is severe stress on water resources. Therefore efficient water management is essential to civil society for betterment of quality of life. The present study emphasizes on the groundwater quality, sources of ground water contamination, variation of groundwater quality and its spatial distribution. The bases for groundwater quality assessment are groundwater bodies and representative monitoring network enabling determination of chemical status of groundwater body. For this study, water samples were collected from various areas of the entire corporation area of Guntur. Water is required for all living organisms of which 1.7% is available as ground water. Water has no calories or any nutrients, but essential for various metabolic activities in our body. Chemical and physical parameters can be tested for identifying the portability of ground water. Electrical conductivity, pH, alkalinity, Total Alkalinity, TDS, Calcium, Magnesium, Sodium, Potassium, Chloride, and Sulphate of the ground water from Guntur district: Different areas of the District were analyzed. Our aim is to check, if the ground water from the above areas are potable or not. As multivariate are present, Data mining technique using JRIP rules was employed for classifying the ground water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=groundwater" title="groundwater">groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20quality%20standards" title=" water quality standards"> water quality standards</a>, <a href="https://publications.waset.org/abstracts/search?q=potability" title=" potability"> potability</a>, <a href="https://publications.waset.org/abstracts/search?q=data%20mining" title=" data mining"> data mining</a>, <a href="https://publications.waset.org/abstracts/search?q=JRIP" title=" JRIP"> JRIP</a>, <a href="https://publications.waset.org/abstracts/search?q=PCA" title=" PCA"> PCA</a>, <a href="https://publications.waset.org/abstracts/search?q=classification" title=" classification"> classification</a> </p> <a href="https://publications.waset.org/abstracts/40645/a-novel-approach-for-the-analysis-of-ground-water-quality-by-using-classification-rules-and-water-quality-index" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/40645.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">430</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">11563</span> Groundwater Quality Monitoring in the Shoush Suburbs, Khouzestan Province, Iran</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohammad%20Tahsin%20Karimi%20Nezhad">Mohammad Tahsin Karimi Nezhad</a>, <a href="https://publications.waset.org/abstracts/search?q=Zaynab%20Shadbahr"> Zaynab Shadbahr</a>, <a href="https://publications.waset.org/abstracts/search?q=Ali%20Gholami"> Ali Gholami</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In recent years many attempts have been made to assess groundwater contamination by nitrates worldwide.

The current study was conducted in Central Limpopo province of South Africa with the overall objective of determining how much water can be withdrawn from the aquifer without producing nonreversible impacts on the groundwater quantity, hence developing a model which can sustainably protect the aquifer. The development was done through the computation of Groundwater Sustainability Index (GSI). Values of GSI close to unity and above indicated overexploitation. In this study, an index of 0.8 was considered as overexploitation. The results indicated that there is potential for higher abstraction rates compared to the current abstraction rates. GSI approach can be used in the management of groundwater aquifer to sustainably develop the resource and also provides water managers and policy makers with fundamental information on where future water developments can be carried out. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=development" title="development">development</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20sustainability%20index" title=" groundwater sustainability index"> groundwater sustainability index</a>, <a href="https://publications.waset.org/abstracts/search?q=model" title=" model"> model</a> </p> <a href="https://publications.waset.org/abstracts/94516/development-of-groundwater-management-model-using-groundwater-sustainability-index" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/94516.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">169</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">11560</span> Coal Mining Safety Monitoring Using Wsn</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Somdatta%20Saha">Somdatta Saha</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The main purpose was to provide an implementable design scenario for underground coal mines using wireless sensor networks (WSNs).

The work mainly concentrated on designing and simulating various alternate scenarios for a typical mine and comparing them based on the obtained results to arrive at a final design. In the Era of embedded technology, the Zigbee protocols are used in more and more applications. Because of the rapid development of sensors, microcontrollers, and network technology, a reliable technological condition has been provided for our automatic real-time monitoring of coal mine.

As groundwater is dynamic and interdisciplinary in nature, an integrated approach of remote sensing (RS) and GIS technique is very useful in various groundwater management studies. Thus, the GIS water balance model (WetSpass) together with remote sensing (RS) can be used to quantify groundwater recharge. This paper discusses the concept of WetSpass in combination with GIS on the quantification of recharge with a view to managing water resources in an integrated framework.

Groundwater is the primary source of water in the United Arab Emirates. However, rapid expansion, population growth, agriculture, and industrial activities have negatively affected these limited water resources. The shortage of water resources has become a serious concern due to the over-pumping of groundwater to meet demand. In addition to the deficit of groundwater, the UAE has one of the highest per capita water consumption rates in the world. In this study, a combination of time-lapse measurements of microgravity and depth to groundwater level in selected wells in Al Ain city was used to estimate the variations in groundwater storage. Al-Ain is the second largest city in Abu Dhabi Emirates and the third largest city in the UAE. The groundwater in this region has been overexploited. Relative gravity measurements were acquired using the Scintrex CG-6 Autograv. This latest generation gravimeter from Scintrex Ltd provides fast, precise gravity measurements and automated corrections for temperature, tide, instrument tilt and rejection of data noise. The CG-6 gravimeter has a resolution of 0.1μGal. The purpose of this study is to measure the groundwater storage changes in the shallow aquifers based on the application of microgravity method. The gravity method is a nondestructive technique that allows collection of data at almost any location over the aquifer. Preliminary results indicate a possible relationship between microgravity and water levels, but more work needs to be done to confirm this. The results will help to develop the relationship between monthly microgravity changes with hydrological and hydrogeological changes of shallow phreatic. The study will be useful in water management considerations and additional future investigations. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Al-Ain" title="Al-Ain">Al-Ain</a>, <a href="https://publications.waset.org/abstracts/search?q=arid%20region" title=" arid region"> arid region</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=microgravity" title=" microgravity"> microgravity</a> </p> <a href="https://publications.waset.org/abstracts/99653/microgravity-hydrological-and-metrological-monitoring-of-shallow-ground-water-aquifer-in-al-ain-uae" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/99653.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">152</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">11557</span> Condition Monitoring System of Mine Air Compressors Based on Wireless Sensor Network</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sheng%20Fu">Sheng Fu</a>, <a href="https://publications.waset.org/abstracts/search?q=Yinbo%20Gao"> Yinbo Gao</a>, <a href="https://publications.waset.org/abstracts/search?q=Hao%20Lin"> Hao Lin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> In the current mine air compressors monitoring system, there are some difficulties in the installation and maintenance because of the wired connection.

Boufekane</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Mitidja coastal groundwater which extends over an area of 1450 km2 is a strategic resource in the Algiers region. The high dependence of the regional economy on the use of this groundwater forces us to have recourse to its artificial recharge from the Wadi El Harrach in its upstream part. This system of artificial recharge has shown its effectiveness in the development of water resource mentioned in the succeeding works in several regions of the world. The objective of this study is to: Increase the reserves of water inputs by infiltration, raise the water level and its good quality in wells and boreholes, reduce losses to the sea, and address seawater intrusion by maintaining balance in the freshwater-saltwater interface in the downstream part of the groundwater basin. After analyzing the situation, it was noticed that a qualitative monitoring of the Wadi water for the groundwater recharge has to be done. For this purpose, we proceeded during three successive years (2010, 2011, and 2012) to the monthly sampling of water in the upstream part of the Wadi El Harrach for chemical analysis. The variation of the sediment transport concentration will be also measured. This monitoring aims to characterize the water quality and avoid clogging in the proposed recharge area. The results of these analyses showed the good chemical quality according to the analyses we performed in the laboratory during the three years, but they are too loaded with suspended matters. We noticed that these fine particles come from the grinding of limestone of sandpit located upstream of the area of the proposed recharge system. This problem can be solved by a water supply upstream of sandpit. For the recharge, we propose the method of using two wells for dual use, which means that it can be used for water supply and extraction. This solution is inexpensive in our case and could easily be used as wells are already drilled in the upstream part. This solution increases over time the piezometric level and also reduce groundwater contamination by saltwater in the downstream part. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20quality" title="water quality">water quality</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20groundwater%20recharge" title=" artificial groundwater recharge"> artificial groundwater recharge</a>, <a href="https://publications.waset.org/abstracts/search?q=Mitidja" title=" Mitidja"> Mitidja</a>, <a href="https://publications.waset.org/abstracts/search?q=North%20Algeria" title=" North Algeria"> North Algeria</a> </p> <a href="https://publications.waset.org/abstracts/21946/study-of-surface-water-quality-in-the-wadi-el-harrach-for-its-use-in-the-artificial-groundwater-recharge-of-the-mitidja-north-algeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/21946.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">11555</span> Seismic Activity and Groundwater Behavior at Kalabsha Area, Aswan, Egypt </h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20M.%20Moustafa">S.

The adsorbent before and after adsorption was characterised by Fourier transform infra-red (FT-IR), X-ray diffraction (XRD) and scanning electron microscopy (SEM), while the amount of vanadium adsorbed was determined by ICP-OES. The batch adsorption method was employed using vanadium concentrations in solution ranging from 50 to 320 mg/L and vanadium tailings seepage water from a South African mine. Also, solution pH, temperature and sorbent mass were varied. Results show that the adsorption capacity was affected by solution pH, temperature, sorbent mass and the initial concentration. Electrical conductivity of the mine water before and after adsorption was measured to estimate the total dissolved solids in the mine water. Equilibrium isotherm results revealed that vanadium sorption follows the Freundlich isotherm, indicating that the surface of the sorbent was heterogeneous. The pseudo-second order kinetic model gave the best fit to the kinetic experimental data compared to the first order and Elovich models. The results of this study may be used to predict the uptake efficiency of South Africa montmorillonite in view of its application for the removal of vanadium from mine water. However, the choice of this adsorbent for the uptake of vanadium or other contaminants will depend on the composition of the effluent to be treated. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=adsorption" title="adsorption">adsorption</a>, <a href="https://publications.waset.org/abstracts/search?q=vanadium" title=" vanadium"> vanadium</a>, <a href="https://publications.waset.org/abstracts/search?q=modified%20montmorillonite" title=" modified montmorillonite"> modified montmorillonite</a>, <a href="https://publications.waset.org/abstracts/search?q=equilibrium" title=" equilibrium"> equilibrium</a>, <a href="https://publications.waset.org/abstracts/search?q=kinetics" title=" kinetics"> kinetics</a>, <a href="https://publications.waset.org/abstracts/search?q=mine%20water" title=" mine water"> mine water</a> </p> <a href="https://publications.waset.org/abstracts/38212/adsorptive-performance-of-surface-modified-montmorillonite-in-vanadium-removal-from-real-mine-water" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/38212.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">433</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">11553</span> Groundwater Quality Assessment Using Water Quality Index and Geographical Information System Techniques: A Case Study of Busan City, South Korea</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Venkatramanan">S.

Datta</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundwater is one of the most important natural resources in many parts of the world; however it is widely polluted due to human activities. Currently, effective and reliable groundwater management and remediation strategies are obtained using characterization of groundwater pollution sources, where the measured data in monitoring locations are utilized to estimate the unknown pollutant source location and magnitude. However, accurately identifying characteristics of contaminant sources is a challenging task due to uncertainties in terms of predicting source flux injection, hydro-geological and geo-chemical parameters, and the concentration field measurement. Reactive transport of chemical species in contaminated groundwater systems, especially with multiple species, is a complex and highly non-linear geochemical process. Although sufficient concentration measurement data is essential to accurately identify sources characteristics, available data are often sparse and limited in quantity. Therefore, this inverse problem-solving method for characterizing unknown groundwater pollution sources is often considered ill-posed, complex and non- unique. Different methods have been utilized to identify pollution sources; however, the linked simulation-optimization approach is one effective method to obtain acceptable results under uncertainties in complex real life scenarios. With this approach, the numerical flow and contaminant transport simulation models are externally linked to an optimization algorithm, with the objective of minimizing the difference between measured concentration and estimated pollutant concentration at observation locations. Concentration measurement data are very important to accurately estimate pollution source properties; therefore, optimal design of the monitoring network is essential to gather adequate measured data at desired times and locations. Due to budget and physical restrictions, an efficient and effective approach for groundwater pollutant source characterization is to design an optimal monitoring network, especially when only inadequate and arbitrary concentration measurement data are initially available. In this approach, preliminary concentration observation data are utilized for preliminary source location, magnitude and duration of source activity identification, and these results are utilized for monitoring network design. Further, feedback information from the monitoring network is used as inputs for sequential monitoring network design, to improve the identification of unknown source characteristics. To design an effective monitoring network of observation wells, optimization and interpolation techniques are used. A simulation model should be utilized to accurately describe the aquifer properties in terms of hydro-geochemical parameters and boundary conditions. However, the simulation of the transport processes becomes complex when the pollutants are chemically reactive. Three dimensional transient flow and reactive contaminant transport process is considered. The proposed methodology uses HYDROGEOCHEM 5.0 (HGCH) as the simulation model for flow and transport processes with chemically multiple reactive species. Adaptive Simulated Annealing (ASA) is used as optimization algorithm in linked simulation-optimization methodology to identify the unknown source characteristics. Therefore, the aim of the present study is to develop a methodology to optimally design an effective monitoring network for pollution source characterization with reactive species in polluted aquifers. The performance of the developed methodology will be evaluated for an illustrative polluted aquifer sites, for example an abandoned mine site in Queensland, Australia. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=monitoring%20network%20design" title="monitoring network design">monitoring network design</a>, <a href="https://publications.waset.org/abstracts/search?q=source%20characterization" title=" source characterization"> source characterization</a>, <a href="https://publications.waset.org/abstracts/search?q=chemical%20reactive%20transport%20process" title=" chemical reactive transport process"> chemical reactive transport process</a>, <a href="https://publications.waset.org/abstracts/search?q=contaminated%20mine%20site" title=" contaminated mine site"> contaminated mine site</a> </p> <a href="https://publications.waset.org/abstracts/39589/unknown-groundwater-pollution-source-characterization-in-contaminated-mine-sites-using-optimal-monitoring-network-design" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/39589.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">231</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">11551</span> Assessing the Influence of Station Density on Geostatistical Prediction of Groundwater Levels in a Semi-arid Watershed of Karnataka</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Sakshi%20Dhumale">Sakshi Dhumale</a>, <a href="https://publications.waset.org/abstracts/search?q=Madhushree%20C."> Madhushree C.</a>, <a href="https://publications.waset.org/abstracts/search?q=Amba%20Shetty"> Amba Shetty</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The effect of station density on the geostatistical prediction of groundwater levels is of critical importance to ensure accurate and reliable predictions. Monitoring station density directly impacts the accuracy and reliability of geostatistical predictions by influencing the model's ability to capture localized variations and small-scale features in groundwater levels. This is particularly crucial in regions with complex hydrogeological conditions and significant spatial heterogeneity. Insufficient station density can result in larger prediction uncertainties, as the model may struggle to adequately represent the spatial variability and correlation patterns of the data. On the other hand, an optimal distribution of monitoring stations enables effective coverage of the study area and captures the spatial variability of groundwater levels more comprehensively. In this study, we investigate the effect of station density on the predictive performance of groundwater levels using the geostatistical technique of Ordinary Kriging. The research utilizes groundwater level data collected from 121 observation wells within the semi-arid Berambadi watershed, gathered over a six-year period (2010-2015) from the Indian Institute of Science (IISc), Bengaluru. The dataset is partitioned into seven subsets representing varying sampling densities, ranging from 15% (12 wells) to 100% (121 wells) of the total well network. The results obtained from different monitoring networks are compared against the existing groundwater monitoring network established by the Central Ground Water Board (CGWB). The findings of this study demonstrate that higher station densities significantly enhance the accuracy of geostatistical predictions for groundwater levels. The increased number of monitoring stations enables improved interpolation accuracy and captures finer-scale variations in groundwater levels. These results shed light on the relationship between station density and the geostatistical prediction of groundwater levels, emphasizing the importance of appropriate station densities to ensure accurate and reliable predictions. The insights gained from this study have practical implications for designing and optimizing monitoring networks, facilitating effective groundwater level assessments, and enabling sustainable management of groundwater resources. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=station%20density" title="station density">station density</a>, <a href="https://publications.waset.org/abstracts/search?q=geostatistical%20prediction" title=" geostatistical prediction"> geostatistical prediction</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20levels" title=" groundwater levels"> groundwater levels</a>, <a href="https://publications.waset.org/abstracts/search?q=monitoring%20networks" title=" monitoring networks"> monitoring networks</a>, <a href="https://publications.waset.org/abstracts/search?q=interpolation%20accuracy" title=" interpolation accuracy"> interpolation accuracy</a>, <a href="https://publications.waset.org/abstracts/search?q=spatial%20variability" title=" spatial variability"> spatial variability</a> </p> <a href="https://publications.waset.org/abstracts/185325/assessing-the-influence-of-station-density-on-geostatistical-prediction-of-groundwater-levels-in-a-semi-arid-watershed-of-karnataka" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/185325.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">58</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">11550</span> Groundwater Vulnerability of Halabja-Khurmal Sub-Basin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Lanja%20F.%20Rauf">Lanja F.

The mean concentration of ²²²Rn in all the groundwater samples was 13.83 Bql-¹. In borehole water, ²²²Rn had a mean value of 20.68 Bql-¹, while it had a mean value of 11.67 Bql-¹ in well water samples. The mean activity concentration of radon obtained from the gold mining communities ranged from 1.6 Bql-¹ from Igun town to 4.8 Bql-¹ from Ilesha town. A higher mean value of 41.8 Bql-¹ was, however, obtained from Ijero, which is the kaolin mining community. The mean annual effective dose due to ingestion and inhalation of radon from groundwater samples was obtained to be 35.35 μSvyr-¹ and 34.86 nSvyr-¹, respectively. The mean annual ingestion dose estimated for well water samples was 29.90 μSvyr-¹, while 52.85 μSvyr-¹ was obtained for borehole water samples. On the other hand, the mean annual inhalation dose for well water was 29.49 nSvyr-¹, while for borehole water, 52.13 nSvyr-¹ was obtained. The mean annual effective dose due to ingestion of radon in groundwater from the gold mining communities ranged from 4.10 μSvyr-¹ from Igun to 13.1 μSvyr-¹ from Ilesha, while a mean value of 106.7 μSvyr-¹ was obtained from Ijero kaolin mining community. For inhalation, the mean value varied from 4.0 nSvyr-¹ from Igun to 12.9 nSvyr-¹ from Ilesha, while 105.2 nSvyr-¹ was obtained from the kaolin mining community. The mean annual effective dose due to ingestion and inhalation is lower than the reference level of 100 μSvyr-¹ recommended by World Health Organization except for values obtained from Ijero kaolin mining community, which exceeded the reference levels. It has been concluded that as far as radon-related health risks are concerned, groundwater from gold mining communities is generally safe, while groundwater from kaolin mining communities needs mitigation and monitoring. It has been discovered that Kaolin mining impacts groundwater with ²²²Rn than gold mining. Also, the radon level in borehole water exceeds its level in well water. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=222Rn" title="222Rn">222Rn</a>, <a href="https://publications.waset.org/abstracts/search?q=Groundwater" title=" Groundwater"> Groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=Radioactivity" title=" Radioactivity"> Radioactivity</a>, <a href="https://publications.waset.org/abstracts/search?q=Annual%20Effective%20Dose" title=" Annual Effective Dose"> Annual Effective Dose</a>, <a href="https://publications.waset.org/abstracts/search?q=Mining." title=" Mining."> Mining.</a> </p> <a href="https://publications.waset.org/abstracts/170865/annual-effective-dose-associated-with-radon-in-groundwater-samples-from-mining-communities-within-the-ife-ilesha-schist-belt-southwestern-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/170865.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">69</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">11547</span> Freshwater Lens Observation: Case Study of Laura Island, Majuro Atoll, Republic of the Marshall Islands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kazuhisa%20Koda">Kazuhisa Koda</a>, <a href="https://publications.waset.org/abstracts/search?q=Tsutomu%20Kobayashi"> Tsutomu Kobayashi</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebecca%20Lorennji"> Rebecca Lorennji</a>, <a href="https://publications.waset.org/abstracts/search?q=Alington%20Robert"> Alington Robert</a>, <a href="https://publications.waset.org/abstracts/search?q=Halston%20DeBrum"> Halston DeBrum</a>, <a href="https://publications.waset.org/abstracts/search?q=Julious%20Lucky"> Julious Lucky</a>, <a href="https://publications.waset.org/abstracts/search?q=Paul%20Paul"> Paul Paul</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Atolls are low-lying small islands with highly permeable ground that does not allow rivers and lakes to develop. As the water resources on these atolls basically rely on precipitation, groundwater becomes a very important water resource during droughts. Freshwater lenses develop as groundwater on relatively large atoll islands and play a key role in the stable water supply. Atoll islands in the Pacific Ocean sometimes suffer from drought due to El Nino. The global warming effects are noticeable, particularly on atoll islands. The Republic of the Marshall Islands in Oceania is burdened with the problems common to atoll islands. About half of its population lives in the capital, Majuro, and securing water resources for these people is a crucial issue. There is a freshwater lens on the largest, Laura Island, which serves as a water source for the downtown area. A serious drought that occurred in 1998 resulted in excessive water intake from the freshwater lens on Laura Island causing up-coning. Up-coning mixes saltwater into groundwater pumped from water-intake wells. Because up-coning makes the freshwater lens unusable, there was a need to investigate the freshwater lens on Laura Island. In this study, we observed the electrical conductivities of the groundwater at different depths in existing monitoring wells to determine the total storage volume of the freshwater lens on Laura Island from 2010 to 2013. Our results indicated that most of the groundwater that seeped into the freshwater lens had flowed out into the sea. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=Atoll%20islands" title="Atoll islands">Atoll islands</a>, <a href="https://publications.waset.org/abstracts/search?q=drought" title=" drought"> drought</a>, <a href="https://publications.waset.org/abstracts/search?q=El-Nino" title=" El-Nino"> El-Nino</a>, <a href="https://publications.waset.org/abstracts/search?q=freshwater%20lens" title=" freshwater lens"> freshwater lens</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20observation" title=" groundwater observation"> groundwater observation</a> </p> <a href="https://publications.waset.org/abstracts/56405/freshwater-lens-observation-case-study-of-laura-island-majuro-atoll-republic-of-the-marshall-islands" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/56405.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">323</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">11546</span> PitMod: The Lorax Pit Lake Hydrodynamic and Water Quality Model</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Silvano%20Salvador">Silvano Salvador</a>, <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Zarrinderakht"> Maryam Zarrinderakht</a>, <a href="https://publications.waset.org/abstracts/search?q=Alan%20Martin"> Alan Martin</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Open pits, which are the result of mining, are filled by water over time until the water reaches the elevation of the local water table and generates mine pit lakes. There are several specific regulations about the water quality of pit lakes, and mining operations should keep the quality of groundwater above pre-defined standards. Therefore, an accurate, acceptable numerical model predicting pit lakes’ water balance and water quality is needed in advance of mine excavation. We carry on analyzing and developing the model introduced by Crusius, Dunbar, et al. (2002) for pit lakes. This model, called “PitMod”, simulates the physical and geochemical evolution of pit lakes over time scales ranging from a few months up to a century or more. Here, a lake is approximated as one-dimensional, horizontally averaged vertical layers. PitMod calculates the time-dependent vertical distribution of physical and geochemical pit lake properties, like temperature, salinity, conductivity, pH, trace metals, and dissolved oxygen, within each model layer. This model considers the effect of pit morphology, climate data, multiple surface and subsurface (groundwater) inflows/outflows, precipitation/evaporation, surface ice formation/melting, vertical mixing due to surface wind stress, convection, background turbulence and equilibrium geochemistry using PHREEQC and linking that to the geochemical reactions. PitMod, which is used and validated in over 50 mines projects since 2002, incorporates physical processes like those found in other lake models such as DYRESM (Imerito 2007). However, unlike DYRESM PitMod also includes geochemical processes, pit wall runoff, and other effects. In addition, PitMod is actively under development and can be customized as required for a particular site. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=pit%20lakes" title="pit lakes">pit lakes</a>, <a href="https://publications.waset.org/abstracts/search?q=mining" title=" mining"> mining</a>, <a href="https://publications.waset.org/abstracts/search?q=modeling" title=" modeling"> modeling</a>, <a href="https://publications.waset.org/abstracts/search?q=hydrology" title=" hydrology"> hydrology</a> </p> <a href="https://publications.waset.org/abstracts/160528/pitmod-the-lorax-pit-lake-hydrodynamic-and-water-quality-model" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/160528.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">158</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">11545</span> Framework for Enhancing Water Literacy and Sustainable Management in Southwest Nova Scotia</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Etienne%20Mfoumou">Etienne Mfoumou</a>, <a href="https://publications.waset.org/abstracts/search?q=Mo%20Shamma"> Mo Shamma</a>, <a href="https://publications.waset.org/abstracts/search?q=Martin%20Tango"> Martin Tango</a>, <a href="https://publications.waset.org/abstracts/search?q=Michael%20Locke"> Michael Locke</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water literacy is essential for addressing emerging water management challenges in southwest Nova Scotia (SWNS), where growing concerns over water scarcity and sustainability have highlighted the need for improved educational frameworks. Current approaches often fail to fully represent the complexity of water systems, focusing narrowly on the water cycle while neglecting critical aspects such as groundwater infiltration and the interconnectedness of surface and subsurface water systems. To address these gaps, this paper proposes a comprehensive framework for water literacy that integrates the physical dimensions of water systems with key aspects of understanding, including processes, energy, scale, and human dependency. Moreover, a suggested tool to enhance this framework is a real-time hydrometric data map supported by a network of water level monitoring devices deployed across the province. These devices, particularly for monitoring dug wells, would provide critical data on groundwater levels and trends, offering stakeholders actionable insights into water availability and sustainability. This real-time data would facilitate deeper understanding and engagement with local water issues, complementing the educational framework and empowering stakeholders to make informed decisions. By integrating this tool, the proposed framework offers a practical, interdisciplinary approach to improving water literacy and promoting sustainable water management in SWNS. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water%20education" title="water education">water education</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20literacy" title=" water literacy"> water literacy</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20management" title=" water management"> water management</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20systems" title=" water systems"> water systems</a>, <a href="https://publications.waset.org/abstracts/search?q=Southwest%20Nova%20Scotia" title=" Southwest Nova Scotia"> Southwest Nova Scotia</a> </p> <a href="https://publications.waset.org/abstracts/191248/framework-for-enhancing-water-literacy-and-sustainable-management-in-southwest-nova-scotia" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/191248.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">31</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">11544</span> Irrigation Water Quality Evaluation in Jiaokou Irrigation District, Guanzhong Basin</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Qiying%20Zhang">Qiying Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Panpan%20Xu"> Panpan Xu</a>, <a href="https://publications.waset.org/abstracts/search?q=Hui%20Qian"> Hui Qian</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundwater is an important water resource in the world, especially in arid and semi-arid regions. In the present study, 141 groundwater samples were collected and analyzed for various physicochemical parameters to assess the irrigation water quality using six indicators (sodium percentage (Na%), sodium adsorption ratio (SAR), magnesium hazard (MH), residual sodium carbonate (RSC), permeability index (PI), and potential salinity (PS)). The results show that the patterns for the average cation and anion concentrations were in decreasing orders of Na<sup>＋</sup> > Mg<sup>2</sup><sup>＋</sup> > Ca<sup>2</sup><sup>＋</sup> > K<sup>＋</sup>and SO<sub>4</sub><sup>2</sup><sup>－</sup> > HCO<sub>3</sub><sup>－</sup> > Cl<sup>－</sup> > NO<sub>3</sub><sup>－</sup> > CO<sub>3</sub><sup>2</sup><sup>－</sup> > F<sup>－</sup>, respectively. The values of Na%, MH, and PS show that most of the groundwater samples are not suitable for irrigation. The same conclusion is drawn from the USSL and Wilcox diagrams. PS values indicate that Cl<sup>－</sup>and SO<sub>4</sub><sup>2</sup><sup>－</sup>have a great influence on irrigation water in Jiaokou Irrigation District. RSC and PI values indicate that more than half of groundwater samples are suitable for irrigation. The finding is beneficial for the policymakers for future water management schemes to achieve a sustainable development goal. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=groundwater%20chemistry" title="groundwater chemistry">groundwater chemistry</a>, <a href="https://publications.waset.org/abstracts/search?q=Guanzhong%20Basin" title=" Guanzhong Basin"> Guanzhong Basin</a>, <a href="https://publications.waset.org/abstracts/search?q=irrigation%20water%20quality%20evaluation" title=" irrigation water quality evaluation"> irrigation water quality evaluation</a>, <a href="https://publications.waset.org/abstracts/search?q=Jiaokou%20Irrigation%20District" title=" Jiaokou Irrigation District"> Jiaokou Irrigation District</a> </p> <a href="https://publications.waset.org/abstracts/130501/irrigation-water-quality-evaluation-in-jiaokou-irrigation-district-guanzhong-basin" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/130501.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">210</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">11543</span> Hydrogeochemical Assessment of Groundwater in Selected Part of Benue State Southern, Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Moses%20Oghenenyoreme%20Eyankware">Moses Oghenenyoreme Eyankware</a>, <a href="https://publications.waset.org/abstracts/search?q=Christian%20Ogubuchi%20Ede"> Christian Ogubuchi Ede</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Groundwater is the principal source for various uses in this study area. The quality and availability of groundwater depend on rock formation within the study area. To effectively study the quality of groundwater, 24 groundwater samples were collected. The study was aimed at investigating the hydrogeochemistry of groundwater, and additionally its suitability for drinking and irrigation purposes. The following parameters were analyzed using the American Public Health Association standard method: pH, turbidity, Ec, TDS, Mg2+, SO42-, NO3¯, Cl-, HCO3¯, K+, Na2+ and Ca2+. Results obtained from Water Quality Index revealed that the groundwater sample fell within good water quality that implies that groundwater is considered fit for drinking purposes. Deduced results obtained from irrigation indices revealed that Permeability Index (PI), Soluble Sodium Percentage (SSP), Sodium Percentage (Na %), Sodium Absorption Ratio (SAR), Kelly Ratio (KR), Magnesium Hazard (MH) ranges from 0.00 to 0.01, 4.04 to 412.9, 0.63 to 257.7, 0.15 to 2.34, 0.09 to 2.57 and 6.84 to 84.55 respectively. Findings from Total hardness revealed that groundwater fell within soft, moderately hard and hard categories. Estimated results obtained from CSMR, RI and LSI showed that groundwater showed corrosion tendency, salinization influenced groundwater at certain sampling points and chloride and sulfate unlikely to interfere with natural formation film. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=water" title="water">water</a>, <a
