Interactions between rainfall and runoff remain challenging due to data limitations and variability in hydrological conditions. This study integrates precipitation data and watershed characteristics in a hydrologic model to assess flood vulnerability of two watersheds (i.e., Maurice River and Raccoon Creek) in southern New Jersey. A sensitivity analysis revealed that land imperviousness exerts the strongest influence on peak runoff predicted by the model. The model was calibrated using past precipitation data and validated against observed peak runoff records. Model performance assessed using the fitting criteria of Normalized Root Mean Square Error and the Nash–Sutcliffe Efficiency demonstrated good agreement between calculated and observed peak runoff data. Model simulations based on 5-, 25-, 50-, 100- and 200-year return period precipitations were employed to predict the peak runoff from the watersheds. Precipitation projections using different scenarios including the high-emissions pathway (i.e., scenario where greenhouse gas emissions continue to increase throughout the twenty-first century, leading to significant climate-related changes) in global climate model were used to calculate the peak runoff. The results indicated a notable increase in peak runoff associated with high-emission precipitation projections from global climate model compared to return period-based peak runoff. These results highlight the redistribution of weather extremes, increased winter precipitation, and heightened flood risks in the watersheds. Overall, the study establishes a practical, data-driven framework for assessing future flood hazards, supporting both technical decision-making and long-term climate adaptation strategies in flood-prone regions.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 9","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-025-02594-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144918532","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}

Laboratory-scale filters (height: 100 cm; diameter: 12 cm) were packed with corn cobs of different particle sizes—small (SPF: 0.8–2.0 cm), medium (MPF: 2.0–3.5 cm), large (LPF: 3.5–5.7 cm), and mixed (MxPF), operating under three hydraulic loading rates (1, 2, and 4 m<sup>3</sup>/m<sup>2</sup>·d) with intermittent feeding cycles (6 h/day).

The effects of magnetic fields (MF) on peach production, the quality of irrigation groundwater, and the properties of irrigated sandy soil in arid environments were also investigated. The study found no discernible differences in the water compatibility standards for irrigation between magnetized water (MW) treated with an MF and non-magnetized water. However, using MW for irrigation greatly improved the productivity and efficiency of using fertilizer and water. When compared to irrigation with non-magnetized water (NMW), this resulted in a significant improvement in peach crop output. The results of the study showed that the amount of soil moisture in the root zone of crops increased significantly when MW irrigation was applied. More precisely within the first 200 m of irrigation from the (MF) device, the moisture content rose from 9.61% in the control treatment to 14.24%. When irrigation was extended from 200 to 400 and 600 m, the amount of moisture in the root zone drastically decreased. This illustrates that the effect of magnetizing irrigation water decreases with increasing distance between the irrigation region and the magnetic device at the field's beginning.

Consequently, this resulted in increased accessibility to water and improved uptake of fertilizers, ultimately leading to enhanced growth and production of peach trees as compared to irrigation with NMW.

To this end, several methods have been proposed over the last decades for measurement site design (MSD). This research presents a novel method for designing measurement sites by using the k-means clustering algorithm as a pre-processing step, followed by utilizing a new optimization algorithm coupled with the fuzzy TOPSIS method as a processing step. The k-means clustering algorithm is employed to narrow down the search space and identify the most suitable candidate nodes. These candidate nodes are then fed into the new optimization algorithm, called the binary genetic-differential evolutionary algorithm (BGDE), to find the optimal nodes, which are then sorted using the fuzzy TOPSIS method. The BGDE considers sensitivity and entropy as objective functions, while the investment cost is taken into account as a constraint. Furthermore, the Bayesian model averaging (BMA) is employed to mitigate the uncertainties in pipe roughness and nodal demands in the hydraulic simulation model. To evaluate the efficiency of the novel method, two WDNs are tested— one from the literature and the other from a real-world case study. Results show that the proposed method reduces the search space, leading to a 70% faster execution, although the accuracy in finding optimal nodes is reduced by roughly 15% compared to the benchmark method.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 9","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-025-02583-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832085","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}

Understanding their sources and enrichment mechanisms is vital for both sustainable salt-lake resource exploitation and freshwater resource security. The Golmud River watershed, a typical hyper-arid endorheic basin on Tibetan Plateau, was investigated to explore the hydrogeochemical characteristics of river water in headwater regions of salt-lake basins, as well as the sources and enrichment mechanisms of trace elements. The results indicate that the hydrochemical types of river water in the headwater regions are predominantly HCO<sub>3</sub>-Ca, Cl-Na, as well as their mixed types. River water hydrochemical components are primarily controlled by rock-water interactions, with minor influence from evaporation. The interacting substances include halite, sulfate minerals, and calcite, sourced from silicate rocks and evaporites. Li and B are highly enriched trace elements in river water of the watershed, exhibiting similar spatial distributions, with the same natural origin. Trace elements in the watershed derive primarily from three sources, including rock-water interactions in Quaternary sediments (PC1), deep magmatic inputs via geothermal fluids (PC2), and permafrost thawing (PC3). PC2 dominates trace element enrichment in river water of the headwater region (83.9%), controlling Sr, U, B, and Li. PC1 primarily governs Co, Ni, Cu, Ba, and W (11.1%), while PC3 regulates Cr and Pb (5.0%). This work elucidates key sources, contributions and enrichment processes of trace elements in river water of the headwater region of arid endorheic salt-lake basins.</p></div>","PeriodicalId":8374,"journal":{"name":"Applied Water Science","volume":"15 9","pages":""},"PeriodicalIF":5.7,"publicationDate":"2025-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s13201-025-02586-z.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145163581","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}
