Lack of studies regarding surface water potential \u0000and demands at the sub-basin level is the reason why this potential was \u0000underutilized. The objective of this study is to assess the surface water \u0000potential and evaluate the current and future demand by using Water Evaluation \u0000and Planning (WEAP) model at Dabus sub-basin. The model was constructed on four \u0000different scenarios starting from the current account (2020) wherein all the \u0000data is filled into the model to estimate the surface water potential and \u0000demands for different sectors. The scenarios include Scenario 1: reference \u0000scenario; Scenario 2: Change in population growth rate; Scenario 3: Irrigation \u0000water demand projection; and Scenario 4: Increased domestic water demand. The \u0000scenario has helped in analyzing “what if” questions. For all the scenarios the \u0000overall demand, coverage and unmet demand were analyzed based on three-time horizon as (2020-2030, 2030-2040, and \u00002040-2050). The model estimated the average annual flow as 6.536 Billion Cubic \u0000Meter (BCM) which is generated from annual precipitation of 14.987 BCM. The \u0000model showed 100% demand coverage for all the scenarios except the irrigation demand \u0000projection scenario which have unmet demand on some of the months of the year.","PeriodicalId":142066,"journal":{"name":"Computational Water, Energy, and Environmental Engineering","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125415033","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The challenge of the \u0000Loka reservoir is that it is located in an ungauged basin where very few \u0000hydrological studies have been carried out, despite the recurrent problems of \u0000access to drinking water. In the purpose to better understand the phenomena \u0000that caused this temporary drying of the dam, the methodology implemented was \u0000based on agro-hydrological modeling with SWAT using a regionalization technique \u0000of a nearby watershed. The model performance was assessed using three \u0000statistical indices (the Nash-Sutcliffe coefficient (NS), the coefficient of determination \u0000(R2) and the percentage of bias (PBIAS)) and the visual appreciation \u0000of hydrographs for monthly series. The statistical indices appear satisfactory \u0000with a NS and R2 ≥ 0.6 both for calibration and validation, and a \u0000PBIAS of -11.2 and -3.8 respectively for calibration and validation. The hydrological \u0000modeling of Loka basin has shown the impact of climate change already reported \u0000by some authors as well as anthropization. Thus, while the reservoir records a \u0000decrease in its water volume estimated at 384,604 m3 each year, the \u0000water demand undergoes an increase of 122,033 m3 per year.","PeriodicalId":142066,"journal":{"name":"Computational Water, Energy, and Environmental Engineering","volume":"89 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-06-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130861938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A rainwater cistern is \u0000a way to improve wildlife habitat because it can be situated in locations that \u0000do not have natural water sources, such as streams or wells that can supply \u0000water for storage. However, the design and sizing of such a system can be \u0000challenging because a number of constantly varying factors must be considered, \u0000such as changing precipitation patterns, the evaporative losses from the \u0000cistern and animal water consumption. No \u0000standardized sizing methodology currently exists for designing wildlife \u0000rainwater cisterns. In this article we present a new method for assisting in \u0000optimally sizing a rainwater cistern. We discuss how we implemented the \u0000quantitative portion of this methodology into a new Excel? model called CISMOD, \u0000which we configured for general use by wildlife professionals. We describe the \u0000methodology for designing a rainwater cistern based on standard engineering \u0000techniques. We then present and discuss our experience in applying the model to \u0000design two rainwater cisterns in an area of the Jemez Mountains in northern New \u0000Mexico, USA. The CISMOD model and a user manual are available at no cost for \u0000wildlife professionals.","PeriodicalId":142066,"journal":{"name":"Computational Water, Energy, and Environmental Engineering","volume":"60 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-04-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126712451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Estuarine and Lake CΟmputer Model three-dimensional \u0000hydrodynamic model has been used, to simulate numerically the effects of the \u0000strong tide conditions, the atmospheric forcing, and the oceanographic conditions. Water age was calculated in \u0000all computational cells and its renewal was \u0000examined with the “pure” water of the open sea \u0000both on the surface layers, where the effect of tide and wind was \u0000pronounced, as well as on the deeper layers and bottom. It was investigated if \u0000in surface layers the tide and the wind restore the water of the study area, \u0000thus preventing its renewal. In the remote area, the mixing and dilution of the \u0000pollutants contained in the treated municipal waste of five installed diffusers \u0000in this complex hydrodynamic field, generated by the aforementioned loads, is \u0000simulated. It was found that even a slight stratification density has the \u0000effect of restricting the vertical mixing and entrapment of dirt in the deeper \u0000layers. The combined impact of municipal \u0000waste effluents on selected areas of high economic, tourist and \u0000environmental value in the Euboean Gulf was assessed. It was found out, that \u0000the Diffuser 2 has a great effect in all the five selected areas, because it \u0000has greater waste water discharge and because of the tide, who produce a \u0000velocity field and transfer the pollutants in longer distances. It was also \u0000investigated indicatively in an important area, whether the presence of tide \u0000contributes to better mixing and dispersing of pollutants and to better water \u0000quality or, on the contrary, as it restores remote pollutants that were \u0000released earlier.","PeriodicalId":142066,"journal":{"name":"Computational Water, Energy, and Environmental Engineering","volume":"2005 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116847210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
