It induces liquefaction, which causes considerable damage to the structure, life support, and piping systems because of ground settlement. As a result, people are incredibly concerned about how to resolve the situation. Previous researchers adopted different ground improvement techniques to reduce the settlement of the structure during earthquakes. This study evaluates the effectiveness of lowering the water table as a technique to mitigate foundation settlement in liquefiable soil. The performance will be evaluated based on foundation settlement and the reduction of excessive pore water pressure. In this study, a scaled model was prepared based on a full-scale shale table experiment conducted at the University of California, San Diego (UCSD). The model ground consists of three soil layers having a relative density of 55%, 45%, and 90%, respectively. A shallow foundation is seated over an unsaturated crust layer. After preparation of the model ground, the water table was measured to be at 45, 40, and 35 cm (from the bottom). Then, the input motions were applied for 10 seconds, with a peak acceleration of 0.25g and a constant frequency of 2.73 Hz. Based on the experimental results, the effectiveness of the lowering water table in reducing the foundation settlement and excess pore water pressure was evident. The foundation settlement was reduced from 50 mm to 5 mm. In addition, lowering the water table as a mitigation measure is a cost-effective way to decrease liquefaction-induced building settlement. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=foundation%20settlement" title="foundation settlement">foundation settlement</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20water%20table" title=" ground water table"> ground water table</a>, <a href="https://publications.waset.org/abstracts/search?q=liquefaction" title=" liquefaction"> liquefaction</a>, <a href="https://publications.waset.org/abstracts/search?q=hake%20table%20test" title=" hake table test"> hake table test</a> </p> <a href="https://publications.waset.org/abstracts/152050/effectiveness-of-lowering-the-water-table-as-a-mitigation-measure-for-foundation-settlement-in-liquefiable-soils-using-1-g-scale-shake-table-test" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/152050.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">113</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">9075</span> Assess Changes in Groundwater Dynamics Caused by Mini Dam Construction in Arid Zone of District Killa Abdullah, Pakistan</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Akhtar%20Malik%20Muhammad">Akhtar Malik Muhammad</a>, <a href="https://publications.waset.org/abstracts/search?q=Agha%20Mirwais"> Agha Mirwais</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Dams are considered to recharge aquifers by raising the water table, especially the ones near wells. The present study investigates the impact of dams on groundwater recharge in Jilga, Pakistan. The comparative analysis of changes in the groundwater table of the year 2012 and 2019 was carried out using ArcGIS 10.5 through the kriging method and remote sensing techniques to evaluate the mini dam's impact on the upstream area. Arc Info Spatial Analyze extension was used to find static water level maps of the years. The water table was observed minimum 67.08 feet and maximum 130.09 feet in 2012 whereas in 2019 the minimum water table level 49.89 feet and maximum 115.85 feet. Groundwater recharge with different ratio was noted, but the most significant was at Rabbani dam with 26ft due to supported lithology conditions and the lowest recharge was found at Garang dam14ft. The overall positive trend indicates the rehabilitation of dead karez and agriculture activities by increasing 36% the vegetation area in 2019. An over 6% increase in human settlement indicates socioeconomic development. Thus, it highlights the need for preferential focus on the construction of the dam so that the water level could be sustained to cater to the agricultural and domestic needs of the local population around the year <p class="card-text"><strong>Keywords:</strong> <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=GIS" title=" GIS"> GIS</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=mini%20dams" title=" mini dams"> mini dams</a>, <a href="https://publications.waset.org/abstracts/search?q=agriculture" title=" agriculture"> agriculture</a> </p> <a href="https://publications.waset.org/abstracts/159460/assess-changes-in-groundwater-dynamics-caused-by-mini-dam-construction-in-arid-zone-of-district-killa-abdullah-pakistan" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/159460.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">84</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">9074</span> Variations in Water Supply and Quality in Selected Groundwater Sources in a Part of Southwest Nigeria</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Samuel%20Olajide%20Babawale">Samuel Olajide Babawale</a>, <a href="https://publications.waset.org/abstracts/search?q=O.%20O.%20Ogunkoya"> O. O.

It also assessed the variation in the elevation of the water table surface to depth of the wells in the months of August and November. This is with a view to determine the level of contamination of the water with respect to land use and anthropogenic activities, and also to determine the variation that occurs in the quantity of well water in the rainy season and the start of the dry season. Results show a random pattern of the distribution of the mapped wells and shows that there is a shallow water table in the study area. The temporal changes in the elevation show that there are no significant variations in the depth of the water table surface over the period of study implying that there is a sufficient amount of water available to the town all year round. It also shows a high concentration of sodium in the water sample analyzed compared to other elements that were considered, which include iron, copper, calcium, and lead. This is attributed majorly to anthropogenic activities through the disposal of waste in landfill sites. There is a low concentration of lead which is a good indication of a reduced level of pollution. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=anthropogenic%20activities" title="anthropogenic activities">anthropogenic activities</a>, <a href="https://publications.waset.org/abstracts/search?q=land%20use" title=" land use"> land use</a>, <a href="https://publications.waset.org/abstracts/search?q=temporal%20changes" title=" temporal changes"> temporal changes</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/93032/variations-in-water-supply-and-quality-in-selected-groundwater-sources-in-a-part-of-southwest-nigeria" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/93032.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">134</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">9073</span> A Survey on Compression Methods for Table Constraints</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=N.%20Gharbi">N.

Table constraints are important for modeling parts of many problems since they list all combinations of allowed or forbidden values. However, they admit practical limitations because they are sometimes too large to be represented in a direct way.

When the Hall voltage is measured for linear displacement, it is converted to angular displacement using arctangent function, which requires a large lookup table. In this paper, a lookup table reduction technique is presented for angle measurement. When the input of the lookup table is small within a certain threshold, the change of the outputs with respect to the change of the inputs is relatively small. Thus, several inputs can share same output, which significantly reduce the lookup table size. Its error analysis was also performed, and the threshold was determined so as to maintain the error less than 1°. When the Hall voltage has 11-bit resolution, the lookup table size is reduced from 1,024 samples to 279 samples. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=hall%20sensor" title="hall sensor">hall sensor</a>, <a href="https://publications.waset.org/abstracts/search?q=angle%20measurement" title=" angle measurement"> angle measurement</a>, <a href="https://publications.waset.org/abstracts/search?q=lookup%20table" title=" lookup table"> lookup table</a>, <a href="https://publications.waset.org/abstracts/search?q=arctangent" title=" arctangent"> arctangent</a> </p> <a href="https://publications.waset.org/abstracts/60862/lookup-table-reduction-and-its-error-analysis-of-hall-sensor-based-rotation-angle-measurement" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/60862.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">336</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">9071</span> Derivation of Technology Element for Automation in Table Formwork in a Tall Building Construction</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Junehyuck%20Lee">Junehyuck Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Dongmin%20Lee"> Dongmin Lee</a>, <a href="https://publications.waset.org/abstracts/search?q=Hunhee%20Cho"> Hunhee Cho</a>, <a href="https://publications.waset.org/abstracts/search?q=Kyung-In%20Kang"> Kyung-In Kang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> A table formwork method has recently been widely applied in reinforced concrete structures in a tall building construction to improve safety and productivity.

The aggravating arsenic toxicity in drinking water is manifested in health problems and ‘arsenicosis’ of people. A social conflict arises between farmers, who intend to grow paddy for livelihoods, and the groundwater authority, which enacts the ‘Regulation Laws’ by putting a check on the excessive installation of private tube-wells for irrigation. Hence, considering the challenges of resource sustainability, health issues, and food security, the study calls for a paradigm shift in policy from further groundwater development to sustainable water resources management and evaluates some strategies integrating supply and demand side management for mitigating the problems. <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=irrigation" title=" irrigation"> irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=paddy%20farming" title=" paddy farming"> paddy farming</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20table%20depletion" title=" water table depletion"> water table depletion</a>, <a href="https://publications.waset.org/abstracts/search?q=arsenic%20pollution" title=" arsenic pollution"> arsenic pollution</a>, <a href="https://publications.waset.org/abstracts/search?q=gangetic%20plains" title=" gangetic plains"> gangetic plains</a> </p> <a href="https://publications.waset.org/abstracts/187055/groundwater-based-irrigation-for-paddy-farming-in-gangetic-plains-of-india-consequences-and-mitigations" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/187055.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">30</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">9069</span> The Resistance of Fish Outside of Water Medium</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Febri%20Ramadhan">Febri Ramadhan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water medium is a vital necessity for the survival of fish.

Although most of parents teach deaf children communication skills in early life, but rarely teach the deficits of balance. The purpose of this study was to investigate whether static balance improved after table tennis training. Table tennis training was provided four times a week for eight weeks to two 12-year-old deaf children. The table tennis training included crossover footwork, sideway attack, backhand block-sideways-flutter forehand attack, and one-on-one tight training. Data were gathered weekly and statistical comparisons were made with a paired t-test. We observed that the dominant leg is better than the non-dominant leg in static balance and girl balance ability is better than boy. The final result shows that table tennis training significantly improves the deaf children’s static balance performance. It indicates that table tennis training on deaf children helps the static balance ability. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=deaf%20children" title="deaf children">deaf children</a>, <a href="https://publications.waset.org/abstracts/search?q=static%20balance" title=" static balance"> static balance</a>, <a href="https://publications.waset.org/abstracts/search?q=table%20tennis" title=" table tennis"> table tennis</a>, <a href="https://publications.waset.org/abstracts/search?q=vestibular%20structure" title=" vestibular structure"> vestibular structure</a> </p> <a href="https://publications.waset.org/abstracts/45989/the-effect-of-static-balance-enhance-by-table-tennis-training-intervening-on-deaf-children" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/45989.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">9067</span> Preparation of Regional Input-Output Table for Fars Province in 2011: GRIT1Method</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Maryam%20Akbarzadeh">Maryam Akbarzadeh</a>, <a href="https://publications.waset.org/abstracts/search?q=F.%20Esmaeilzadeh"> F.

Obtained estimates by non-statistical methods have low confidence coefficient. Therefore, integrated methods for this purpose are suggested by recent input–output studies. In this study, first GRIT method is introduced as an appropriate integrated method for preparation of input-output table of Fars province. Next, input-output table is prepared for Fars province using this method. Therefore, this study is based on input-output table of national economy in 2001. Necessary modifications performed in the field of changes at level of prices and differences of regional trade compared with other areas at national level. Moreover, up to date statistics and information and technical experts view on the various economic sectors along with input-output table 33 was used in 2011 followed by investigation of general structure of the province economy based on the amounts of added value obtained from this table. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=grit" title="grit">grit</a>, <a href="https://publications.waset.org/abstracts/search?q=input-output" title=" input-output"> input-output</a>, <a href="https://publications.waset.org/abstracts/search?q=table" title=" table"> table</a>, <a href="https://publications.waset.org/abstracts/search?q=regional" title=" regional "> regional </a> </p> <a href="https://publications.waset.org/abstracts/3237/preparation-of-regional-input-output-table-for-fars-province-in-2011-grit1method" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/3237.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">9066</span> Evaluation of the Conditions of Managed Aquifer Recharge in the West African Basement Area</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Palingba%20Aim%C3%A9%20Marie%20Doilkom">Palingba Aimé Marie Doilkom</a>, <a href="https://publications.waset.org/abstracts/search?q=Mahamadou%20Ko%C3%AFta"> Mahamadou Koïta</a>, <a href="https://publications.waset.org/abstracts/search?q=Jean-michel%20Vouillamoz"> Jean-michel Vouillamoz</a>, <a href="https://publications.waset.org/abstracts/search?q=Angelbert%20Biaou"> Angelbert Biaou</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Most African populations rely on groundwater in rural areas for their consumption. Indeed, in the face of climate change and strong demographic growth, groundwater, particularly in the basement, is increasingly in demand. The question of the sustainability of water resources in this type of environment is therefore becoming a major issue. Groundwater recharge can be natural or artificial. Unlike natural recharge, which often results from the natural infiltration of surface water (e.g. a share of rainfall), artificial recharge consists of causing water infiltration through appropriate developments to artificially replenish the water stock of an aquifer. Artificial recharge is, therefore, one of the measures that can be implemented to secure water supply, combat the effects of climate change, and, more generally, contribute to improving the quantitative status of groundwater bodies. It is in this context that the present research is conducted with the aim of developing artificial recharge in order to contribute to the sustainability of basement aquifers in a context of climatic variability and constantly increasing water needs of populations. In order to achieve the expected results, it is therefore important to determine the characteristics of the infiltration basins and to identify the areas suitable for their implementation. The geometry of the aquifer was reproduced, and the hydraulic properties of the aquifer were collected and characterized, including boundary conditions, hydraulic conductivity, effective porosity, recharge, Van Genuchten parameters, and saturation indices. The aquifer of the Sanon experimental site is made up of three layers, namely the saprolite, the fissured horizon, and the healthy basement. Indeed, the saprolite and the fissured medium were considered for the simulations. The first results with FEFLOW model show that the water table reacts continuously for the first 100 days before stabilizing. The hydraulic charge increases by an average of 1 m. The further away from the basin, the less the water table reacts. However, if a variable hydraulic head is imposed on the basins, it can be seen that the response of the water table is not uniform over time. The lower the basin hydraulic head, the less it affects the water table. These simulations must be continued by improving the characteristics of the basins in order to obtain the appropriate characteristics for a good recharge. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=basement%20area" title="basement area">basement area</a>, <a href="https://publications.waset.org/abstracts/search?q=FEFLOW" title=" FEFLOW"> FEFLOW</a>, <a href="https://publications.waset.org/abstracts/search?q=infiltration%20basin" title=" infiltration basin"> infiltration basin</a>, <a href="https://publications.waset.org/abstracts/search?q=MAR" title=" MAR"> MAR</a> </p> <a href="https://publications.waset.org/abstracts/162819/evaluation-of-the-conditions-of-managed-aquifer-recharge-in-the-west-african-basement-area" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/162819.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">76</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">9065</span> Correlation between Physical Fitness and Performance and Grade of Table Tennis of Middle School Students</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Yisong%20Cong">Yisong Cong</a>, <a href="https://publications.waset.org/abstracts/search?q=Mingming%20Guo"> Mingming Guo</a>, <a href="https://publications.waset.org/abstracts/search?q=Xiaozan%20Wang"> Xiaozan Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Yizhi%20Zhang"> Yizhi Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Qingqing%20Yuan"> Qingqing Yuan</a> </p> <p class="card-text"><strong>Abstract:</strong></p> This study is to test the correlation between the Physical Fitness (PF) of middle school students and their performance and sports grade of table tennis. Methods: 398 middle school students from Shanghai Tongji No.2 Middle School participated in the study, including 232 boys and 166 girls. Each participant participated in the Chinese Students’ Physical Fitness Test (CSPFT), including BMI, 50-meter running, vital capacity, sitting body flexion, standing long jump, 800-meter running, 1000-meter running, pull-ups, and sit-ups. Test scores were converted to a percentage score according to the CSPFT guidelines. In addition, each student participated in the Nation Junior Table Tennis grade test, and completed the table tennis sports grade assessment of 1-9. Results: There is a significant positive correlation between the scores of multiple PF tests and the total scores of table tennis, such as BMI (r = 0.15, p < 0.01), standing long jump (r = 0.15, p < 0.05), 800-meter run (r = 0.02, p <0.01); The scores of multiple PF are positively correlated with table tennis grade, such as vital capacity (r = 0.1, p < 0.01) and 50-meter running (r = 0.18, p < 0.05). At the same time, the sit-ups performance showed a significant negative correlation with the table tennis performance (r = -0.08, p < 0.01); There is no significant correlation between the other PF indicators and the performance and grade of table tennis. Conclusions: This study shows that there is a corresponding relationship between some PF indicators of middle school students and their table tennis performance and table tennis grade，but the specific form and reason of the relationship need to be further explored. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=middle%20school%20students" title="middle school students">middle school students</a>, <a href="https://publications.waset.org/abstracts/search?q=physical%20fitness" title=" physical fitness"> physical fitness</a>, <a href="https://publications.waset.org/abstracts/search?q=table%20tennis%20grade" title=" table tennis grade"> table tennis grade</a>, <a href="https://publications.waset.org/abstracts/search?q=table%20tennis%20performance" title=" table tennis performance"> table tennis performance</a> </p> <a href="https://publications.waset.org/abstracts/126554/correlation-between-physical-fitness-and-performance-and-grade-of-table-tennis-of-middle-school-students" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/126554.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">160</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">9064</span> Estimating Groundwater Seepage Rates: Case Study at Zegveld, Netherlands</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Wondmyibza%20Tsegaye%20Bayou">Wondmyibza Tsegaye Bayou</a>, <a href="https://publications.waset.org/abstracts/search?q=Johannes%20C.%20Nonner"> Johannes C.

The theoretical background to these methods is put together in this study. The methodology was applied to a case study area at Zegveld following the advice of the Water Board Stichtse Rijnlanden. Data collection has been from various offices and a field campaign in the winter of 2008/09. In this complex confining layer of the study area, the location of the phreatic groundwater table is at a shallow depth compared to the piezometric water level. Data were available for the model years 1989 to 2000 and winter 2008/09. The higher groundwater table shows predominately-downward seepage in the study area. Results of the study indicated that net recharge to the groundwater table (precipitation excess) and the ditch system are the principal sources for seepage across the complex confining layer. Especially in the summer season, the contribution from the ditches is significant. Water is supplied from River Meije through a pumping system to meet the ditches' water demand. The groundwater seepage rate was distributed unevenly throughout the study area at the nature reserve averaging 0.60 mm/day for the model years 1989 to 2000 and 0.70 mm/day for winter 2008/09. Due to data restrictions, the seepage rates were mainly determined based on the Darcian method. Furthermore, the water balance approach and the tracer methods are applied to compute the flow exchange within the ditch system. The site had various validated groundwater levels and vertical flow resistance data sources. The phreatic groundwater level map compared with TNO-DINO groundwater level data values overestimated the groundwater level depth by 28 cm. The hydraulic resistance values obtained based on the 3D geological map compared with the TNO-DINO data agreed with the model values before calibration. On the other hand, the calibrated model significantly underestimated the downward seepage in the area compared with the field-based computations following the Darcian approach. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=groundwater%20seepage" title="groundwater seepage">groundwater seepage</a>, <a href="https://publications.waset.org/abstracts/search?q=phreatic%20water%20table" title=" phreatic water table"> phreatic water table</a>, <a href="https://publications.waset.org/abstracts/search?q=piezometric%20water%20level" title=" piezometric water level"> piezometric water level</a>, <a href="https://publications.waset.org/abstracts/search?q=nature%20reserve" title=" nature reserve"> nature reserve</a>, <a href="https://publications.waset.org/abstracts/search?q=Zegveld" title=" Zegveld"> Zegveld</a>, <a href="https://publications.waset.org/abstracts/search?q=The%20Netherlands" title=" The Netherlands"> The Netherlands</a> </p> <a href="https://publications.waset.org/abstracts/171496/estimating-groundwater-seepage-rates-case-study-at-zegveld-netherlands" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/171496.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">85</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">9063</span> Optimal Uses of Rainwater to Maintain Water Level in Gomti Nagar, Uttar Pradesh, India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Alok%20Saini">Alok Saini</a>, <a href="https://publications.waset.org/abstracts/search?q=Rajkumar%20Ghosh"> Rajkumar Ghosh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water is nature's important resource for survival of all living things, but freshwater scarcity exists in some parts of world. This study has predicted that Gomti Nagar area (49.2 sq. km.) will harvest about 91110 ML of rainwater till 2051 (assuming constant and present annual rainfall). But 17.71 ML of rainwater was harvested from only 53 buildings in Gomti Nagar area in the year 2021. Water level will be increased (rise) by 13 cm in Gomti Nagar from such groundwater recharge. The total annual groundwater abstraction from Gomti Nagar area was 35332 ML (in 2021). Due to hydrogeological constraints and lower annual rainfall, groundwater recharge is less than groundwater abstraction. The recent scenario is only 0.07% of rainwater recharges by RTRWHs in Gomti Nagar. But if RTRWHs would be installed in all buildings then 12.39% of rainwater could recharge groundwater table in Gomti Nagar area. But if RTRWHs would be installed in all buildings then 12.39% of rainwater could recharge groundwater table in Gomti Nagar area. Gomti Nagar is situated in 'Zone–A' (water distribution area) and groundwater is the primary source of freshwater supply. Current scenario indicates only 0.07% of rainwater recharges by RTRWHs in Gomti Nagar. In Gomti Nagar, the difference between groundwater abstraction and recharge will be 735570 ML in 30 yrs. Statistically, all buildings at Gomti Nagar (new and renovated) could harvest 3037 ML of rainwater through RTRWHs annually. The most recent monsoonal recharge in Gomti Nagar was 10813 ML/yr. Harvested rainwater collected from RTRWHs can be used for rooftop irrigation, and residential kitchen and gardens (home grown fruit and vegetables). According to bylaws, RTRWH installations are required in both newly constructed and existing buildings plot areas of 300 sq. m or above. Harvested rainwater is of higher quality than contaminated groundwater. Harvested rainwater from RTRWHs can be considered water self-sufficient. Rooftop Rainwater Harvesting Systems (RTRWHs) are least expensive, eco-friendly, most sustainable, and alternative water resource for artificial recharge. This study also predicts about 3.9 m of water level rise in Gomti Nagar area till 2051, only when all buildings will install RTRWHs and harvest for groundwater recharging. As a result, this current study responds to an impact assessment study of RTRWHs implementation for the water scarcity problem in the Gomti Nagar area (1.36 sq.km.). This study suggests that common storage tanks (recharge wells) should be built for a group of at least ten (10) households and optimal amount of harvested rainwater will be stored annually. Artificial recharge from alternative water sources will be required to improve the declining water level trend and balance the groundwater table in this area. This over-exploitation of groundwater may lead to land subsidence, and development of vertical cracks. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=aquifer" title="aquifer">aquifer</a>, <a href="https://publications.waset.org/abstracts/search?q=aquitard" title=" aquitard"> aquitard</a>, <a href="https://publications.waset.org/abstracts/search?q=artificial%20recharge" title=" artificial recharge"> artificial recharge</a>, <a href="https://publications.waset.org/abstracts/search?q=bylaws" title=" bylaws"> bylaws</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater" title=" groundwater"> groundwater</a>, <a href="https://publications.waset.org/abstracts/search?q=monsoon" title=" monsoon"> monsoon</a>, <a href="https://publications.waset.org/abstracts/search?q=rainfall" title=" rainfall"> rainfall</a>, <a href="https://publications.waset.org/abstracts/search?q=rooftop%20rainwater%20harvesting%20system" title=" rooftop rainwater harvesting system"> rooftop rainwater harvesting system</a>, <a href="https://publications.waset.org/abstracts/search?q=RTRWHs%20water%20table" title=" RTRWHs water table"> RTRWHs water table</a>, <a href="https://publications.waset.org/abstracts/search?q=water%20level" title=" water level"> water level</a> </p> <a href="https://publications.waset.org/abstracts/150750/optimal-uses-of-rainwater-to-maintain-water-level-in-gomti-nagar-uttar-pradesh-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150750.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">97</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">9062</span> Association Between Hip Internal and External Rotation Range of Motion and Low Back Pain in Table Tennis Players</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Kaili%20Wang">Kaili Wang</a>, <a href="https://publications.waset.org/abstracts/search?q=Botao%20Zhang"> Botao Zhang</a>, <a href="https://publications.waset.org/abstracts/search?q=Enming%20Zhang"> Enming Zhang</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background: Low back pain (LBP) is a common problem affecting athletes' training and competition. Although the association between a limited hip range of motion and prevalence of low back pain has been studied extensively, it has not been studied in table tennis. Aim: The main purposes of this study in table tennis players were (1) to investigate if there is a difference in hip internal rotation (HIR) and external rotation (HER) range of motion (ROM) between players with LBP and players without LBP and (2) to analyze the association between HIR and HER ROM and LBP. Methods: Forty-six table tennis players from the Chinese table tennis team were evaluated for passive maximum HIR and HER ROM. LBP was retrospectively recorded for the last 12 months before the date of ROM assessment by a physical therapist. The data were analyzed the difference in HIR and HER ROM between players with LBP and players without LBP by Mann-Whitney U test, and the association between the difference in HIR and HER ROM and LBP was analyzed via a binary logistic regression. Results: The 54% of players had developed LBP during the retrospective study period. Signiﬁcant diﬀerence between LBP group and the asymptomatic group for HIR ROM (z=4.007, p<0.001) was observed. Diﬀerence between LBP group and asymptomatic group for HER ROM (z=1.117, p=0.264) was not signiﬁcant. Players who had HIR ROM deficit had an increased risk of LBP compared with players without HIR ROM deficit (OR=5.344, 95%CI: 1.006-28.395, P=0.049). Conclusion: HIR ROM of a table tennis player with LBP was less than a table tennis player without LBP. Compared with player whose HIR ROM was normal, player who had HIR ROM deficit appeared to have a higher risk for LBP. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=assessment" title="assessment">assessment</a>, <a href="https://publications.waset.org/abstracts/search?q=injury%20prevention" title=" injury prevention"> injury prevention</a>, <a href="https://publications.waset.org/abstracts/search?q=low%20back%20pain" title=" low back pain"> low back pain</a>, <a href="https://publications.waset.org/abstracts/search?q=table%20tennis%20players" title=" table tennis players"> table tennis players</a> </p> <a href="https://publications.waset.org/abstracts/154477/association-between-hip-internal-and-external-rotation-range-of-motion-and-low-back-pain-in-table-tennis-players" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/154477.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">111</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">9061</span> Comparison of Different Techniques to Estimate Surface Soil Moisture</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=S.%20Farid%20F.%20Mojtahedi">S.

There are different causes of land subsidence; most notably, ground-water overdraft and severe weather conditions. Subsidence of the land surface due to ground water overdraft is caused by an increase in the intergranular pressure in unconsolidated aquifers, which results in a loss of buoyancy of solid particles in the zone dewatered by the falling water table and accordingly compaction of the aquifer. On the other hand, exploitation of underground water may result in significant changes in degree of saturation of soil layers above the water table, increasing the effective stress in these layers, and considerable soil settlements. This study focuses on estimation of soil moisture at surface using different methods. Specifically, different methods for the estimation of moisture content at the soil surface, as an important term to solve Richard’s equation and estimate soil moisture profile are presented, and their results are discussed through comparison with field measurements obtained from Yanco1 station in south-eastern Australia. Surface soil moisture is not easy to measure at the spatial scale of a catchment. Due to the heterogeneity of soil type, land use, and topography, surface soil moisture may change considerably in space and time. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=artificial%20neural%20network" title="artificial neural network">artificial neural network</a>, <a href="https://publications.waset.org/abstracts/search?q=empirical%20method" title=" empirical method"> empirical method</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=surface%20soil%20moisture" title=" surface soil moisture"> surface soil moisture</a>, <a href="https://publications.waset.org/abstracts/search?q=unsaturated%20soil" title=" unsaturated soil"> unsaturated soil</a> </p> <a href="https://publications.waset.org/abstracts/57123/comparison-of-different-techniques-to-estimate-surface-soil-moisture" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/57123.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">359</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">9060</span> Seismic Response of Structure Using a Three Degree of Freedom Shake Table</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Ketan%20N.%20Bajad">Ketan N.

There are various experimental techniques such as pseudo-dynamic tests – nonlinear structural dynamic technique, real time pseudo dynamic test and shaking table test method that can be employed to verify the seismic performance of structures. Shake table is a device that is used for shaking structural models or building components which are mounted on it. It is a device that simulates a seismic event using existing seismic data and nearly truly reproducing earthquake inputs. This paper deals with the use of shaking table test method to check the response of structure subjected to earthquake. The various types of shake table are vertical shake table, horizontal shake table, servo hydraulic shake table and servo electric shake table. The goal of this experiment is to perform seismic analysis of a civil engineering structure with the help of 3 degree of freedom (i.e. in X Y Z direction) shake table. Three (3) DOF shaking table is a useful experimental apparatus as it imitates a real time desired acceleration vibration signal for evaluating and assessing the seismic performance of structure. This study proceeds with the proper designing and erection of 3 DOF shake table by trial and error method. The table is designed to have a capacity up to 981 Newton. Further, to study the seismic response of a steel industrial building, a proportionately scaled down model is fabricated and tested on the shake table. The accelerometer is mounted on the model, which is used for recording the data. The experimental results obtained are further validated with the results obtained from software. It is found that model can be used to determine how the structure behaves in response to an applied earthquake motion, but the model cannot be used for direct numerical conclusions (such as of stiffness, deflection, etc.) as many uncertainties involved while scaling a small-scale model. The model shows modal forms and gives the rough deflection values. The experimental results demonstrate shake table as the most effective and the best of all methods available for seismic assessment of structure. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=accelerometer" title="accelerometer">accelerometer</a>, <a href="https://publications.waset.org/abstracts/search?q=three%20degree%20of%20freedom%20shake%20table" title=" three degree of freedom shake table"> three degree of freedom shake table</a>, <a href="https://publications.waset.org/abstracts/search?q=seismic%20analysis" title=" seismic analysis"> seismic analysis</a>, <a href="https://publications.waset.org/abstracts/search?q=steel%20industrial%20shed" title=" steel industrial shed"> steel industrial shed</a> </p> <a href="https://publications.waset.org/abstracts/98669/seismic-response-of-structure-using-a-three-degree-of-freedom-shake-table" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/98669.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">140</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">9059</span> Technical Option Brought Solution for Safe Waste Water Management in Urban Public Toilet and Improved Ground Water Table</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Chandan%20Kumar">Chandan Kumar</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Background and Context: Population growth and rapid urbanization resulted nearly 2 Lacs migrants along with families moving to Delhi each year in search of jobs. Most of these poor migrant families end up living in slums and constitute an estimated population of 1.87 lacs every year. Further, more than half (52 per cent) of Delhi’s population resides in places such as unauthorized and resettled colonies. Slum population is fully dependent on public toilet to defecate. In Public toilets, manholes either connected with Sewer line or septic tank. Septic tank connected public toilet faces major challenges to dispose of waste water. They have to dispose of waste water in outside open drain and waste water struck out side of public toilet complex and near to the slum area. As a result, outbreak diseases such as Malaria, Dengue and Chikungunya in slum area due to stagnated waste water. Intervention and Innovation took place by Save the Children in 21 Public Toilet Complexes of South Delhi and North Delhi. These public toilet complexes were facing same waste water disposal problem. They were disposing of minimum 1800 liters waste water every day in open drain. Which caused stagnated water-borne diseases among the nearest community. Construction of Soak Well: Construction of soak well in urban context was an innovative approach to minimizing the problem of waste water management and increased water table of existing borewell in toilet complex. This technique made solution in Ground water recharging system, and additional water was utilized in vegetable gardening within the complex premises. Soak well had constructed with multiple filter media with inlet and safeguarding bed on surrounding surface. After construction, soak well started exhausting 2000 liters of waste water to raise ground water level through different filter media. Finally, we brought a change in the communities by constructing soak well and with zero maintenance system. These Public Toilet Complexes were empowered by safe disposing waste water mechanism and reduced stagnated water-borne diseases. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=diseases" title="diseases">diseases</a>, <a href="https://publications.waset.org/abstracts/search?q=ground%20water%20recharging%20system" title=" ground water recharging system"> ground water recharging system</a>, <a href="https://publications.waset.org/abstracts/search?q=soak%20well" title=" soak well"> soak well</a>, <a href="https://publications.waset.org/abstracts/search?q=toilet%20complex" title=" toilet complex"> toilet complex</a>, <a href="https://publications.waset.org/abstracts/search?q=waste%20water" title=" waste water"> waste water</a> </p> <a href="https://publications.waset.org/abstracts/58853/technical-option-brought-solution-for-safe-waste-water-management-in-urban-public-toilet-and-improved-ground-water-table" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/58853.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">551</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">9058</span> Improve B-Tree Index’s Performance Using Lock-Free Hash Table</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Zhanfeng%20Ma">Zhanfeng Ma</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhiping%20Xiong"> Zhiping Xiong</a>, <a href="https://publications.waset.org/abstracts/search?q=Hu%20Yin"> Hu Yin</a>, <a href="https://publications.waset.org/abstracts/search?q=Zhengwei%20She"> Zhengwei She</a>, <a href="https://publications.waset.org/abstracts/search?q=Aditya%20P.%20Gurajada"> Aditya P.

However, there are extra overheads to maintain a separate hash index, for example, hash mapping for all data records must always be maintained, which results in more memory space consumption; locking, logging and other mechanisms are needed to guarantee ACID, which affects the concurrency and scalability of the system. To relieve the overheads, Hash Cached B-tree (HCB) index is proposed in this paper, which consists of a standard disk-based B-tree index and an additional in-memory lock-free hash table. Initially, only the B-tree index is constructed for all data records, the hash table is built on the fly based on runtime workload, only data records accessed by point queries are indexed using hash table, this helps reduce the memory footprint. Changes to hash table are done using compare-and-swap (CAS) without performing locking and logging, this helps improve the concurrency and avoid contention. The hash table is also optimized to be cache conscious. HCB index is implemented in SAP ASE database, compared with the standard B-tree index, early experiments and customer adoptions show significant performance improvement. This paper provides an overview of the design of HCB index and reports the experimental results. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=B-tree" title="B-tree">B-tree</a>, <a href="https://publications.waset.org/abstracts/search?q=compare-and-swap" title=" compare-and-swap"> compare-and-swap</a>, <a href="https://publications.waset.org/abstracts/search?q=lock-free%20hash%20table" title=" lock-free hash table"> lock-free hash table</a>, <a href="https://publications.waset.org/abstracts/search?q=point%20queries" title=" point queries"> point queries</a>, <a href="https://publications.waset.org/abstracts/search?q=range%20queries" title=" range queries"> range queries</a>, <a href="https://publications.waset.org/abstracts/search?q=SAP%20ASE%20database" title=" SAP ASE database"> SAP ASE database</a> </p> <a href="https://publications.waset.org/abstracts/72665/improve-b-tree-indexs-performance-using-lock-free-hash-table" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/72665.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">286</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">9057</span> Contribution of Remote Sensing and GIS to the Study of the Impact of the Salinity of Sebkhas on the Quality of Groundwater: Case of Sebkhet Halk El Menjel (Sousse)</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gannouni%20Sonia">Gannouni Sonia</a>, <a href="https://publications.waset.org/abstracts/search?q=Hammami%20Asma"> Hammami Asma</a>, <a href="https://publications.waset.org/abstracts/search?q=Saidi%20Salwa"> Saidi Salwa</a>, <a href="https://publications.waset.org/abstracts/search?q=Rebai%20Noamen"> Rebai Noamen</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Water resources in Tunisia have experienced quantitative and qualitative degradation, especially when talking about wetlands and Sbekhas. Indeed, the objective of this work is to study the spatio-temporal evolution of salinity for 29 years (from 1987 to 2016). A study of the connection between surface water and groundwater is necessary to know the degree of influence of the Sebkha brines on the water table. The evolution of surface salinity is determined by remote sensing based on Landsat TM and OLI/TIRS satellite images of the years 1987, 2007, 2010, and 2016. The processing of these images allowed us to determine the NDVI(Normalized Difference Vegetation Index), the salinity index, and the surface temperature around Sebkha. In addition, through a geographic information system(GIS), we could establish a map of the distribution of salinity in the subsurface of the water table of Chott Mariem and Hergla/SidiBouAli/Kondar. The results of image processing and the calculation of the index and surface temperature show an increase in salinity downstream of in addition to the sebkha and the development of vegetation cover upstream and the western part of the sebkha. This richness may be due both to contamination by seawater infiltration from the barrier beach of Hergla as well as the passage of groundwater to the sebkha. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=spatio-temporal%20monitoring" title="spatio-temporal monitoring">spatio-temporal monitoring</a>, <a href="https://publications.waset.org/abstracts/search?q=salinity" title=" salinity"> salinity</a>, <a href="https://publications.waset.org/abstracts/search?q=satellite%20images" title=" satellite images"> satellite images</a>, <a href="https://publications.waset.org/abstracts/search?q=NDVI" title=" NDVI"> NDVI</a>, <a href="https://publications.waset.org/abstracts/search?q=sebkha" title=" sebkha"> sebkha</a> </p> <a href="https://publications.waset.org/abstracts/150699/contribution-of-remote-sensing-and-gis-to-the-study-of-the-impact-of-the-salinity-of-sebkhas-on-the-quality-of-groundwater-case-of-sebkhet-halk-el-menjel-sousse" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/150699.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">132</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">9056</span> Flood Analysis of Domestic Rooftop Rainwater Harvesting in Low Lying Flood Plain Areas at Gomti Nagar In Rain-Dominated Monsoon Climates</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Rajkumar%20Ghosh">Rajkumar Ghosh</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Rapid urbanization, rising population, changing lifestyles and in-migration, Lucknow is groundwater over-exploited area, with an abstract rate of 1968 m3/day/km2 in Gomti Nagar. The groundwater situation in Gomti Nagar is deteriorating day-by-day. According to the work, the calculated annual water deficiency in Gomti Nagar area will be 28061 Million Litre (ML) in 2022. Within 30 yrs., the water deficiency will be 735570 ML (till 2051). The calculated groundwater recharge in Gomti Nagar was 10813 ML/y (in 2022). The annual groundwater abstraction from Gomti Nagar area was 35332 ML/yr. (in 2022). Bye-laws (≥ 300 sq.m) existing RTRWHs can recharge 17.71 ML/yr. in Gomti Nagar area. The existing RTRWHs are contributing 0.07% for recharging groundwater table. In Gomti Nagar, the water level is dropping at a rate of 1.0 metre per year, and the depth of the water table is less than 30 metre below ground level (mbgl). Natural groundwater recharge is affected by the geomorphological conditions of the surrounding area. Gomti Nagar is located on the erosional terrace (Te) and depositional terrace (d) of the Gomti River. The flood plain in Lucknow city is less active due to the embankments on the both sides of the Gomti River. The alluvium is composed of clay sandy up to a depth of 30m, and the alignment of the Gomti River reveals the presence of sandy soil at shallow depths. Aquifer depth 120 metre. Recharge as in Gomti Nagar (it may vary) 0 – 150 metre. Infiltration rates in alluvial floodplains range from 0.8 to 74 cm/hr. Geologically and Geomorphologically support rapid percolation of rainwater through alluvium in Gomti Nagar, Lucknow city, Uttar Pradesh. Over-exploitation of groundwater causes natural hazards viz. land subsidence, development of cracks on roads and buildings, development of vacuum and compactness of soil/clay which leads towards land subsidence, devastating effects on natural stream flow. Gomti River already transitioning phase from ‘effluent’ to ‘influent’, and saline intrusion in Aquifer –II (among Five aquifers in Lucknow city). A 250 m long crack developed in 2007 due to groundwater depletion in Dullu Khera and Vader Khera village of Kakori, Uttar Pradesh. The groundwater table of Lucknow is declining and water table imbalance occurs due to 17 times less recharge than groundwater exploitation. Uttar Pradesh along with four states have extracted 49% of groundwater in the entire country. In Gomti Nagar area, 27305 no of houses are present and available build up area 3.8 sq. km (60% of plot area) based on Lucknow Development Authority (LDA) Master plan 2031. If RTRWHs would install in all the houses, then 12% harvested rainwater contribute to the water table in Gomti Nagar area. Till 2051, Gomti Nagar area will harvest 91110 ML of rainwater. There are minimalistic chances that any incidence of flood can occur due to RTRWH. Thus, it can conclud that RTRWH is not related to flood happening in urban areas viz. Gomti Nagar. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=RTRWH" title="RTRWH">RTRWH</a>, <a href="https://publications.waset.org/abstracts/search?q=aquifer" title=" aquifer"> aquifer</a>, <a href="https://publications.waset.org/abstracts/search?q=groundwater%20table" title=" groundwater table"> groundwater table</a>, <a href="https://publications.waset.org/abstracts/search?q=rainwater" title=" rainwater"> rainwater</a>, <a href="https://publications.waset.org/abstracts/search?q=infiltration" title=" infiltration"> infiltration</a> </p> <a href="https://publications.waset.org/abstracts/168779/flood-analysis-of-domestic-rooftop-rainwater-harvesting-in-low-lying-flood-plain-areas-at-gomti-nagar-in-rain-dominated-monsoon-climates" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/168779.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">9055</span> Traverse Surveying Table Simple and Sure</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Hamid%20Fallah">Hamid Fallah</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Creating surveying stations is the first thing that a surveyor learns; they can use it for control and implementation in projects such as buildings, roads, tunnels, monitoring, etc., whatever is related to the preparation of maps.

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">9053</span> Experimental Analysis of Tuned Liquid Damper (TLD) with Embossments Subject to Random Excitation</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Saberi">Mohamad Saberi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arash%20Sohrabi"> Arash Sohrabi</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tuned liquid damper is one the passive structural control ways which has been used since mid-1980 decade for seismic control in civil engineering.

This study adds to this research by showing that Taylor’s Law leads to a model that reasonably describes the relationship between life expectancy at birth (e0, which also is equal to mean age at death in a life table) and variance at age of death in seven World Bank regional life tables measured at two points in time, 1970 and 2000. Using as a benchmark a non-random sample of four Japanese female life tables covering the period from 1950 to 2004, the study finds that the simple linear model provides reasonably accurate estimates of variance in age at death in a life table from e0, where the latter range from 60.9 to 85.59 years. Employing 2017 life tables from the Human Mortality Database, the simple linear model is used to provide estimates of variance at age in death for six countries, three of which have high e0 values and three of which have lower e0 values. The paper provides a substantive interpretation of Taylor’s Law relative to e0 and concludes by arguing that reasonably accurate estimates of variance in age at death in a period life table can be calculated using this approach, which also can be used where e0 itself is estimated rather than generated through the construction of a life table, a useful feature of the model. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=empirical%20pattern" title="empirical pattern">empirical pattern</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20age%20at%20death%20in%20a%20life%20table" title=" mean age at death in a life table"> mean age at death in a life table</a>, <a href="https://publications.waset.org/abstracts/search?q=mean%20age%20of%20a%20stationary%20population" title=" mean age of a stationary population"> mean age of a stationary population</a>, <a href="https://publications.waset.org/abstracts/search?q=stationary%20population" title=" stationary population"> stationary population</a> </p> <a href="https://publications.waset.org/abstracts/138835/taylors-law-and-relationship-between-life-expectancy-at-birth-and-variance-in-age-at-death-in-period-life-table" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/138835.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">330</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">9050</span> Development of Ready Reckoner Charts for Easy, Convenient, and Widespread Use of Horrock’s Apparatus by Field Level Health Functionaries in India</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Gumashta%20Raghvendra">Gumashta Raghvendra</a>, <a href="https://publications.waset.org/abstracts/search?q=Gumashta%20Jyotsna"> Gumashta Jyotsna</a> </p> <p class="card-text"><strong>Abstract:</strong></p> Aim and Objective of Study : The use of Horrock’s Apparatus by health care worker requires onsite mathematical calculations for estimation of ‘volume of water’ and ‘amount of bleaching powder’ necessary as per the serial number of first cup showing blue coloration after adding freshly prepared starch-iodide indicator solution. In view of the difficulties of two simultaneous calculations required to be done, the use of Horrock’s Apparatus is not routinely done by health care workers because it is impractical and inconvenient Material and Methods: Arbitrary use of bleaching powder in wells results in hyper-chlorination or hypo-chlorination of well defying the purpose of adequate chlorination or non-usage of well water due to hyper-chlorination. Keeping this in mind two nomograms have been developed, one to assess the volume of well using depth and diameter of well and the other to know the quantity of bleaching powder to b added using the number of the cup of Horrock’s apparatus which shows the colour indication. Result & Conclusion: Out of thus developed two self-speaking interlinked easy charts, first chart will facilitate bypassing requirement of formulae ‘πr2h’ for water volume (ready reckoner table with depth of water shown on ‘X’ axis and ‘diameter of well’ on ‘Y’ axis) and second chart will facilitate bypassing requirement formulae ‘2ab/455’ (where ‘a’ is for ‘serial number of cup’ and ‘b’ is for ‘water volume’, while ready reckoner table showing ‘water volume’ shown on ‘X’ axis and ‘serial number of cup’ on ‘Y’ axis). The use of these two charts will help health care worker to immediately known, by referring the two charts, about the exact requirement of bleaching powder. Thus, developed ready reckoner charts will be easy and convenient to use for ensuring prevention of water-borne diseases occurring due to hypo-chlorination, especially in rural India and other developing countries. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=apparatus" title="apparatus">apparatus</a>, <a href="https://publications.waset.org/abstracts/search?q=bleaching" title=" bleaching"> bleaching</a>, <a href="https://publications.waset.org/abstracts/search?q=chlorination" title=" chlorination"> chlorination</a>, <a href="https://publications.waset.org/abstracts/search?q=Horrock%E2%80%99s" title=" Horrock’s"> Horrock’s</a>, <a href="https://publications.waset.org/abstracts/search?q=nomogram" title=" nomogram"> nomogram</a> </p> <a href="https://publications.waset.org/abstracts/29810/development-of-ready-reckoner-charts-for-easy-convenient-and-widespread-use-of-horrocks-apparatus-by-field-level-health-functionaries-in-india" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/29810.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">483</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">9049</span> Drippers Scaling Inhibition of the Localized Irrigation System by Green Inhibitors Based on Plant Extracts</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Driouiche%20Ali">Driouiche Ali</a>, <a href="https://publications.waset.org/abstracts/search?q=Karmal%20Ilham"> Karmal Ilham</a> </p> <p class="card-text"><strong>Abstract:</strong></p> The Agadir region is characterized by a dry climate, ranging from arid attenuated by oceanic influences to hyper-arid. The water mobilized in the agricultural sector of greater Agadir is 95% of underground origin and comes from the water table of Chtouka. The rest represents the surface waters of the Youssef Ben Tachfine dam. These waters are intended for the irrigation of 26880 hectares of modern agriculture. More than 120 boreholes and wells are currently exploited. Their depth varies between 10 m and 200 m and the unit flow rates of the boreholes are 5 to 50 l/s. A drop in the level of the water table of about 1.5 m/year, on average, has been observed during the last five years. Farmers are thus called upon to improve irrigation methods. Thus, localized or drip irrigation is adopted to allow rational use of water. The importance of this irrigation system is due to the fact that water is applied directly to the root zone and its compatibility with fertilization. However, this irrigation system faces a thorny problem which is the clogging of pipes and drippers. This leads to a lack of uniformity of irrigation over time. This so-called scaling phenomenon, the consequences of which are harmful (cleaning or replacement of pipes), leads to considerable unproductive expenditure. The objective set by this work is the search for green inhibitors likely to prevent this phenomenon of scaling. This study requires a better knowledge of these waters, their physico-chemical characteristics and their scaling power. Thus, using the "LCGE" controlled degassing technique, we initially evaluated, on pure calco-carbonic water at 30°F, the scaling-inhibiting power of some available plant extracts in our region of Souss-Massa. We then carried out a comparative study of the efficacy of these green inhibitors. The action of the most effective green inhibitor on real agricultural waters was then studied. <p class="card-text"><strong>Keywords:</strong> <a href="https://publications.waset.org/abstracts/search?q=green%20inhibitors" title="green inhibitors">green inhibitors</a>, <a href="https://publications.waset.org/abstracts/search?q=localized%20irrigation" title=" localized irrigation"> localized irrigation</a>, <a href="https://publications.waset.org/abstracts/search?q=plant%20extracts" title=" plant extracts"> plant extracts</a>, <a href="https://publications.waset.org/abstracts/search?q=scaling%20inhibition" title=" scaling inhibition"> scaling inhibition</a> </p> <a href="https://publications.waset.org/abstracts/155083/drippers-scaling-inhibition-of-the-localized-irrigation-system-by-green-inhibitors-based-on-plant-extracts" class="btn btn-primary btn-sm">Procedia</a> <a href="https://publications.waset.org/abstracts/155083.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">82</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">9048</span> Experimental Analysis of Tuned Liquid Damper (TLD) for High Raised Structures</h5> <div class="card-body"> <p class="card-text"><strong>Authors:</strong> <a href="https://publications.waset.org/abstracts/search?q=Mohamad%20Saberi">Mohamad Saberi</a>, <a href="https://publications.waset.org/abstracts/search?q=Arash%20Sohrabi"> Arash Sohrabi </a> </p> <p class="card-text"><strong>Abstract:</strong></p> Tuned liquid damper is one the passive structural control ways which has been used since mid-1980 decade for seismic control in civil engineering.

Each team holds a position in the table with which it is possible to determine the highest and lowest points for that team. This paper proposes an optimized search space based on the minimum and maximum number of points which can be gained by each team to produce and enumerate the possible states for a football tournament final table. The proposed search space minimizes producing the invalid states which cannot occur during a football tournament. The generated states are filtered by a validity checking algorithm which seeks to reach a tournament graph based on a generated state. Thus, the algorithm provides a way to determine which team’s wins, draws and loses values guarantee a particular table position. The paper also presents and discusses the experimental results of the approach on the tournaments with up to eight teams. Comparing with a blind search algorithm, our proposed approach reduces generating the invalid states up to 99.99%, which results in a considerable optimization in term of the execution time. <p
