To quantify the effect of climate variability on natural systems on Earth in the future, the use of regional climate models (RCMs) as a tool is mandatory. Thus, the use of well-validated RCM provides efficient climate data; and predicts future climate variability over agroecological zones (AEZs). Eleven RCMs from CORDEX-Ethiopia were evaluated to simulate maximum temperature (T_max), minimum temperature (T_min) and rainfall variability over space and time, to validate their performance and to select the best-fit models. The temporal variability T_max and rainfall was smaller with a CV of 10 %, indicating uniform distribution over stations. However, CV for T_min over stations shows satisfactory distributions. Most of the evaluated RCMs have a better capability to capture the spatial variability of rainfall,T_max, and T_min in some stations. However, some of the RCMs can handle the spatial variability of T_max while others are not. None of the RCMs can handle the spatial variability of T_min in Debre Birhan, Majete, and Kewat AEZs. In general, most RCMs can capture the spatial and temporal variability of rainfall and temperature. It might be better to use the ensemble average of the output from these RCMs for precise estimation of data than specific RCMs. Therefore, this work could suggest the use of high-resolution RCMs for the projection of temperature and rainfall over different AEZs.</p></div>","PeriodicalId":101279,"journal":{"name":"Water-Energy Nexus","volume":"7 ","pages":"Pages 87-102"},"PeriodicalIF":0.0,"publicationDate":"2024-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2588912524000018/pdfft?md5=16888af8e2a7089d9f39605b3849dc52&pid=1-s2.0-S2588912524000018-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139637459","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These pollutants generally consist of dangerous heavy metals and metalloids. In rural locations, hardness and chlorides are among the most dangerous problems of groundwater. Chlorides are regulated in the quality of drinking water because excessive quantities can cause disease. Due to its alkaline nature, both the gaseous and liquid forms of hardness can be irritating to the eyes, respiratory system, and epidermis. The acute biologic effects of hardness and chlorides in humans are dependent on dose and proportionate to their concentration. This includes the amount that is eaten by the body as well as the length of time that the body is exposed to the substance. The naturally occurring physiochemical mechanism known as biosorption is what permits particular biomass to passively concentrate and bind pollutants to its cellular structure. Biosorption can only occur in specific environments. This is a metabolically inert process that does not need any kind of energy, and the quantity of pollutants that a sorbent is able to remove is dependent on its kinetic equilibrium as well as the makeup of its cellular surface. When it came to the biosorption of heavy metals from water, each biosorbent had its own unique set of physical, chemical, and biological features. After the removal of heavy metals, the biosorption process may be made more cost-effective by renewing and reprocessing the biosorbent. This is done after the heavy metals have been removed. In the process of biosorption, many types of bioreactors are used in order to successfully remove the metal ions from huge volumes of water.</p></div>","PeriodicalId":101279,"journal":{"name":"Water-Energy Nexus","volume":"7 ","pages":"Pages 39-76"},"PeriodicalIF":0.0,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2588912524000031/pdfft?md5=24b9edc6473c72d08547e15134e1e71e&pid=1-s2.0-S2588912524000031-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139653716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Water of building industry and domestic water are two major contributors to total water consumption that cannot be ignored. This paper seeks to emphasize the effects of urban sprawl on water competition between building industry and residents. To achieve this objective, a framework for quantifying the water usage of the life cycle of the building was first constructed. Additionally, the degree of urban sprawl and water competition between domestic and building industry was computed. This study characterized the evolution path of urban sprawl and water competition using standard deviation ellipse. Spatial econometric models were used to determine the impact of urban sprawl on water competition. The results indicate that there is a high spatial correlation between urban sprawl and water competition. The center of gravity of China's urban sprawl is consistent with the north-to-south movement of water competition. As economic sprawl increases by 1%, water competition will rise by 0.440%. As the population expands by 1%, the water competition index shifts by 0.018%. Moreover, 0.017% more water was used for every 1% increase in land sprawl.</p></div>","PeriodicalId":101279,"journal":{"name":"Water-Energy Nexus","volume":"7 ","pages":"Pages 26-38"},"PeriodicalIF":0.0,"publicationDate":"2024-01-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S258891252400002X/pdfft?md5=98aa51763a1dedb4960ee759afadd0a7&pid=1-s2.0-S258891252400002X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139504212","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Ayigebire watershed was one of the most erosion-susceptible watersheds in Menz Gera district of Ethiopia. At the outlet, there was a soil dam (Godebe soil dam) which covered 12.7 ha. The dam was designed for irrigation purposes wishing to serve 378 households on 68 ha of land. However, the dam was facing a huge challenge of siltation due to the soil erosion brought from the upper reaches of the watershed. Therefore, the purpose of this study was to identify the erosion-affected area and to estimate the watershed's annual sediment yield delivered to the dam. The study used rainfall, DEM and satellite image data obtained from different sources. The result shows the annual soil loss of the watershed was 47 tons ha⁻¹ yr⁻¹. The regions along the drainage lines were identified as erosion hotspot areas and they contribute 76.6% of soil loss. The estimated annual sediment washed from the watershed and reached the Godebe soil dam was found to be 8710 m³ (60969 m³) since the time the dam became operational). From the finding, it could be concluded that the watershed was highly vulnerable to soil loss above the tolerable soil loss limit of the country i.e., 10 tons ha⁻¹ yr⁻¹. Therefore, it’s recommended the high erosion and sediment-producing areas along the waterlines and side banks of the dam get priority for management.</p></div>","PeriodicalId":101279,"journal":{"name":"Water-Energy Nexus","volume":"7 ","pages":"Pages 124-134"},"PeriodicalIF":0.0,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S258891252300036X/pdfft?md5=bfc2f19c801ceebd86ff7e312a940de5&pid=1-s2.0-S258891252300036X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139455946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
