This study employed a two-stage sampling technique to select representative sampling locations, including boreholes and hand-dug wells. Seven towns in Ibeju-Lekki were sampled for this study. A total of 14 sampling points were chosen for the analysis of 15 water parameters, which included five physical parameters (NTU, TCU, E.C. TDS and TSS), eight (8) chemical parameters (pH, T.H. Ca, Mg, Cl-, NO3-, SO42- and Fe), and two (2) microbial parameters (E.Coli count and BOD) after standard procedures. The data obtained were subjected to statistical analysis using Python to assess correlations between the physicochemical parameters. The results were compared with water quality standards set by the World Health Organization (WHO) and the Nigerian Standard for Drinking Water Quality (NSDWQ). In addition, a water quality index (WQI) was calculated to provide a single numerical expression of the overall water quality. The findings revealed variations in the quality of borehole and well water, with some parameters exceeding the recommended standards, such as magnesium and iron concentrations. The presence of elevated turbidity, total dissolved solids (TDS), and electrical conductivity (E.C.) in well water indicated potential contamination sources. The study also demonstrated the significance of understanding physicochemical parameter correlations in groundwater quality assessment. The WQI results emphasized that groundwater is suitable for various purposes, including animals and other domestic and agricultural purposes. However, the paper recommended routine monitoring and thorough treatment to address the high magnesium (Mg) and iron (Fe) levels in both borehole and well water sources.","PeriodicalId":34430,"journal":{"name":"Water Science","volume":"51 1","pages":"409 - 425"},"PeriodicalIF":0.0,"publicationDate":"2023-11-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139242995","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}

With the aid of ArcGIS 10.7, the spatial distribution of physiochemical parameters and major ions (Ca2+, Mg2+, K+, Na+, HCO−3, SO42-, Cl− and PO43-) were determined. The cations and anions of the groundwater trended as Ca2+ > Mg2+ > K+ > Na+ and HCO−3> SO42- > Cl− > PO43-, respectively, while all values are within World Health Organization (WHO) allowable limit except Ca2+. The positive correlation among major ions illustrated similarities in the sources and distributions based on principal component analysis, while the cluster analysis established the complexity of the hydrogeochemical processes.

Thus, the analysis and investigation for various pressure distributions, velocity, erosion-rate, and vortex structure were carefully demonstrated in this study. In addition, the slurry pump’s wear or erosion characteristics were carefully examined, and it was found that as the flow rate increases, the wear of the suction surface worsens.

The water shortage problem led to the development of several water saving techniques. One of the waters saving techniques in irrigation is the partial root-zone drying (PRD) method. Tow field experiments accompanied by a modeling study were carried out during seasons 2020/2021 and 2021/2022, respectively, using four deficit irrigation strategies [FI (100% of full irrigation), DI1 (0.75FI), DI2 (0.5FI) where water was supplied to both sides of the mango trees and DI3 (Partial Root-zone Drying, PRD = 0.5FI) where water was supplied to a single side of each tree in an alternating manner)]. The four irrigation methods were designated as the study’s major plots. Then, for the purpose of adding compost, each main plot was divided into four smaller plots [NC (No-Compost), C12 (12 ton ha−1), C18 (18 ton ha−1) and C24 (24 ton ha−1)] to investigate the effects of such treatments on increasing water productivity, yield, and the quality of mango fruits. The results indicated that adding compost with PRD irrigation method decreased water stress throughout the root zone and increased the yield, water productivity and fruit quality. Compost addition C24 (24 ton ha−1) with PRD irrigation increased the amount of soil organic matter and microorganism activity when compared to other treatments. Additionally, C24 treatment improved mango quality under both FI and PRD treatments, the PRD technique enhanced fruit yields by 3.8% and 7.3% and water productivity by 51.6% and 53.8% for 2021 and 2022 seasons, respectively, compared to FI, while reducing the applied irrigation water by 50% for each season. In comparison to other irrigation strategies, the PRD strategy had shown superior outcomes in enhancing the yield, water productivity, and quality of mango yield. With the use of compost “C24” as organic matter fertilizer, PRD proved to be an effective dual technique to save water and increase productivity. Under both current and future water scarcity caused by climate change, it could be a successful adaptation technique. The SALTMED model produced accurate simulations of the soil moisture content, mango production, and water productivity during the two seasons.","PeriodicalId":34430,"journal":{"name":"Water Science","volume":"65 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135093243","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}

It can be used for different purposes of life, depending on its quality. The quality can be categorized for irrigation based on many items such as sodium percentage, permeability index (PI), magnesium hazard (MH), Kelley ratio (KR), and water quality index (WQI). Those items can be expressed and presented in Geographic Information System (GIS) format. This study aims to compare the WQI with the other items for expressing the suitability of groundwater for irrigation in GIS format. This study is conducted in the south Nile Delta region, Egypt. Seventy-two groundwater samples are collected and analyzed for pH, EC, total dissolved solids, soluble cations and soluble anions, iron, and manganese. These parameters are used to calculate the WQI considering their permissible limits of FAO, while the other items were calculated using some parameters based on their equations. The results reveal that, due to sodium percentage, there are three orders from five orders, of which 53% are good, 39% are permissible, and 8% are doubtful. Considering PI, the results were 7% for class 1 and 93% for class 2. Regarding MH, the results ranged between 6% (not suitable for irrigation) and 94% (suitable for irrigation). Depending on KR, 82% of the samples are suitable for irrigation, while 18% are not suitable for irrigation. The results of WQI illustrate that 76.4% of the total studied samples are excellent for irrigation and 23.6 are good for irrigation. All the results are represented using ArcGIS 10.1 program to clear the spatial distribution of the groundwater suitability for irrigation. The use of WQI with GIS is considered the best tool to represent and categorize the suitability of groundwater for irrigation.","PeriodicalId":34430,"journal":{"name":"Water Science","volume":"4 2","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136376363","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}

Therefore, this work aimed to estimate the spatial distribution of economic and ecological Water Use Profit (WUP) and relate it to the Normalized Differential Water Index (NDWI) and evapotranspiration in the San Luis Potosí state, México. When calculating or obtaining the NDWI, this indicator is associated with values of evapotranspiration concentrations that are obtained spatially in the various portions of the territory, since in SLP territory the climate and soil moisture vary from one region to another, as there are 4 different regions. The methodology in this study involved a multitemporal analysis of the WUP in the State corresponding to 1990, 2000, 2010, and 2015, since it is an indicator that measures the uses and water exploitation in a region obtained over time, which is why it is called multitemporal, since we are talking about a 25-year period of analysis and the result is different from one place to another in San Luis Potosi territory. This study was realized through the application of economic and ecological indicators which were evaluated, considering the economic and ecological activities that use water in the region; therefore, the behavior of ETR depends on the area and the economic and/or ecological activities that have been carried out in the period. Also, for understanding the behavior of water reservoirs in the basins in the study area, the NDWI was obtained from Landsat 8 imagery. The results of NDWI showed that, from 1990 to 2015, there was a decrease in moisture content, becoming more evident in 2000. This study found that secondary and tertiary activities significantly influence yearly economic value. From 1990 to 2000, the Gross Domestic Product (GDP) value doubled, while from 2000 to 2010 tripled, and for 2015 the increase was nearly 25% compared to 2010. The WUPeconomic’s and WUPecological’s highest values were obtained in the most important urban areas of the state because secondary and tertiary activities are mainly developed. It is precisely with this reasoning that the behavior of relationship between ETR and WUP is vital for the understanding of water consumption generated. Finally, the ETR’s highest values are in the Huasteca region of the state.","PeriodicalId":34430,"journal":{"name":"Water Science","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135645421","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}

In the Salmon Barrier, adding two steps downstream of weir was previously suggested as an effective method for reducing the risk of drowning downstream of this dam. Given the effect of steps on the flow pattern downstream of the weir, the occurrence of dangerous submerged flows at different tailwaters was predicted, and the flow pattern expected at variable tailwaters was studied in comparison with the flow pattern passing over the sharp crested weir. According to the results, the submerged flow pattern downstream of the dam is a combination of the submerged flow pattern over the abrupt drop at low tailwaters and that over the sharp crested weir at high water levels. Consequently, similar correlations for predicting the flow regime downstream of these structures can be presented to predict the flow pattern at different tailwaters. The flow pattern over the step was compared with that over the abrupt drop, and a few diagrams were presented for predicting the occurrence of different flow patterns based on the submergence ratio of steps. Given the similarity of the flow pattern with those in the literature for sharp crested weirs, the flow pattern was also investigated at higher tailwaters. The comparison of correlations developed in this study indicated that the flow pattern approaches that reported in the literature for sharp crested weirs with increasing discharge.","PeriodicalId":34430,"journal":{"name":"Water Science","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-09-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135149309","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}
