Greywater sources differ in ease and cost of reuse, with limited studies on the effects of irrigation with different sources on soil properties and subsequent rainwater remediation. Thus, this study compared the effect of four major household greywater sources (shower (SH), dishwasher (DW) and liquid and powdered laundry detergent (LLD and PLD)) on soil properties and rainwater remediation potential of two contrasting (albic Planosol (bleached) and Lixisol (rhodic)) topsoils under Mediterranean climate conditions. Summer irrigation with the greywater and tap water sources was simulated (370 mm) followed by winter rainfall simulation (370 mm). Soil chemical, physical and microbial properties were determined after each simulation. Irrigation with SH and LLD greywaters was least harmful to soil chemistry; however, LLD decreased soil infiltration rate by 48–53%, and SH resulted in hydrophobic crusting. Irrigation with PLD and DW greywater was most damaging, resulting in alkalisation, sodification and salinisation accompanied by soil structural degradation, decreasing infiltration by 85–100%. All treatments reduced soil bacterial diversity and species richness. Rain simulation was only able to reduce sodicity and salinity associated with PLD and DW application on the rhodic soil, as the clay fraction was more stable, permitting some infiltration. Therefore, PLD and DW greywaters should not be used directly for irrigation, especially on bleached soils, as this can halt rainwater percolation. Furthermore, use of less chemically harmful SH or LLD liquid greywaters could result in undesirable soil physical problems in the long term.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 5","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-025-02460-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143883757","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study assessed a box culvert with three outlets of different baffle arrangements and blockage rates of 0%, 25%, and 50% at the inlet. For unsteady flow conditions, two hydrographs were created, each containing seven unique flow discharges. Conversely, for steady flow conditions, flow rates of 13.8 <i>l/s</i> and 20 <i>l/s</i> were employed. The sediment and flow scenarios were meticulously chosen to maintain clear water throughout the experimental procedures.

In-depth analysis of baffles application versus the base case scenario under the same blockage conditions showed that the deepest scour depths were typically found further from the outlet in the base case scenario.

The aim of this study was to carry out a detailed assessment of the water resources in the region, focussing on the most important aspects affecting water quality. The main objectives were to calculate various water quality indices for drinking and irrigation purposes, to develop an automated system using convolutional neural networks (CNN) to predict these indices and to increase the transparency of these models using explainable artificial intelligence (XAI) methods. Methodologically, the study used CNN algorithms optimised by Bayesian techniques for the prediction of eight water quality indices, coupled with SHAPley Additive exPlanations (SHAP) analysis under XAI to interpret the complex decision-making processes of these models. This dual approach enabled a comprehensive and insightful assessment of water quality. Using a robust dataset from the Aseer region, eight water quality indices were calculated, revealing significant variations and highlighting areas of concern. In this study, the entropy weight-based DWQI averaged 77.90 with a high standard deviation (std) of 39.08, reflecting considerable variability. The automated CNN models demonstrated robust performance in predicting water quality indices, with high accuracy (R<sup>2</sup> = 0.959 in training and 0.945 in testing) for sodium percentage (Na%). However, the Magnesium Hazard (MH) index showed lower accuracy, suggesting possible overfitting and the need for further optimisation. SHAP analysis highlighted chloride, sulphate, and total dissolved solids as key contributors to the WQI, while sodium and calcium were significant for the sodium adsorption ratio. These insights enhance understanding of parameter influence on water quality assessments.

This study introduces a novel approach for mapping groundwater recharge potential zones across a 1,100 <span>(hbox {km}^2)</span> area using geographic information systems, the analytic hierarchy process, total dissolved solids levels, and the receiver operating characteristic curve. The study incorporates the precipitation data from NASA LaRC POWER to address the spatial and temporal limitations of local meteorological data and enhance model performance. The results revealed a clear spatial distribution of recharge potential, with a maximum of 8.66 observed in the northern mountainous areas and a gradual decrease toward the southern region. A key innovation of this study is the use of total dissolved solids levels for model validation, revealing a strong relationship with recharge dynamics. The receiver operating characteristic curve analysis yielded an area under the curve of 0.835, indicating high model reliability. The approach incorporates easily accessible data, including NASA LaRC POWER, the digital elevation model, Landsat imagery, and total dissolved solids, offering a replicable and adaptable framework, particularly useful in regions with limited hydrogeological data. These findings provide valuable insights into groundwater recharge processes and highlight the importance of total dissolved solids as a practical tool for model validation.

Another significant challenge is usage of pump stations for lifting irrigation water to elevated lands considering cost recovery of cultivated crops. Egypt, which is a semi-arid region, has been facing challenges due to limited water resources and insufficient agricultural production. Egyptian Government seeks to expand agricultural projects to increase production. This paper focuses on expansion project along command area of El Nasr Canal, as a case study, which is supplied from El Nubaria Canal through a cascade of five pump stations irrigating new reclaimed land in north-west Egypt Delta. The main goal of this study is to analyze cost–benefit of lifting water to irrigate different crops along El Nasr Canal. The study also aims to assess sufficiency of lifting water along each pumping station and investigate shortages/surpluses until delivering water to end users. Modern irrigation is applied to only 57% of El Nasr Canal area, while surface irrigation is used in remaining areas. Cost analysis showed that total cost of lifting water for each pump station is (2.794, 5.591, 8.247, 12.138, and 17.044) × 10<sup>–3</sup> $/m<sup>3</sup>, respectively. Feasibility analysis indicated that sunflower, groundnuts, sugar beet, apples, and mandarins are non-feasible for most pumping stations zones even with usage of modern irrigation. Results showed irrigation demand requirements exceeded water supply causing severe shortages of 883.30 MCM/year. Accordingly, the study presented different scenarios to provide decision-makers with solutions for better management of water and cropping pattern. Methodology developed in this study presents a useful guide to analyze and assess water resources and agricultural sustainability in similar regions.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 5","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-025-02426-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143845698","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
