The Soil and Water Assessment Tool (SWAT) is a well-established eco-hydrological model that has been extensively applied to watersheds across the globe. This work reviews over two decades (2002–2022) of SWAT studies conducted on Mediterranean watersheds. A total 260 articles have identified since earliest documented use in catchment back 2002; which 62% were carried out Greece, Italy, or Spain. applications increased significantly recent years 86% reviewed papers published past decade. major objective for most works was check applicability specific great number publications included procedures calibration validation reported performance results. region mainly cover water resources quantity quality assessment hydrologic environmental impacts evaluation land climate changes. Nevertheless, tendency towards multi-purpose revealed. numerous examples combined with other tools techniques outline model's flexibility. Several performed constructive comparisons between watersheds' responses compared models methods. effects inputs outputs innovative modifications improvements also focus some surveyed articles. However, significant difficulties regarding data availability, as these are either scarce, poor resolution not freely available. Therefore, it highly recommended identify develop accurate testing optimize performance.

Abstract Evaluating Best Management Practices (BMPs) in watersheds using hydrologic and water quality models can help to establish an effective watershed management. Soil Water Assessment Tool (SWAT) was applied Big Sunflower River Watershed (BSRW) the Stovall Sherard (SSW) evaluate BMP’s impact at field scale respectively. SWAT calibrated validated for streamflow, sediment yield, total nitrogen (TN), phosphorous (TP) outlets of three sub-basins BSRW, within SSW. BMP scenarios check-dam, tail pond, vegetative filter strips (VFS), nutrient management, tillage management were evaluated their efficacy reducing loads scales.

Current Status of Emerging Contaminant Models and Their Applications Concerning the Aquatic Environment: A Review

Water, Journal Year: 2025, Volume and Issue: 17(1), P. 85 - 85

Published: Jan. 1, 2025

Increasing numbers of emerging contaminants (ECs) detected in water environments require a detailed understanding these chemicals’ fate, distribution, transport, and risk aquatic ecosystems. Modeling is useful approach for determining ECs’ characteristics their behaviors environments. This article proposes systematic taxonomy EC models addresses gaps the comprehensive analysis applications. The reviewed include conventional quality models, multimedia fugacity machine learning (ML) models. Conventional have higher prediction accuracy spatial resolution; nevertheless, they are limited functionality can only be used to predict contaminant concentrations Fugacity excellent at depicting how travel between different environmental media, but cannot directly analyze variations parts same media because model assumes that constant within compartment. Compared other ML applied more scenarios, such as identification assessments, rather than being confined concentrations. In recent years, with rapid development artificial intelligence, surpassed becoming one newest hotspots study ECs. primary challenge faced by outcomes difficult interpret understand, this influences practical value an some extent.

A review of modeling pesticides in freshwaters: Current status, progress achieved and desirable improvements.

Environmental Pollution, Journal Year: 2022, Volume and Issue: 316, P. 120553 - 120553

Published: Nov. 5, 2022

This study comprises a critical review of modeling pesticides in surface waters. The aim was to update the status use models simulate fate from diffuse sources. ISI papers were selected on Scopus and information concerning areas, type (herbicides, fungicides insecticides), model, methodology adopted (i.e., calibration and/or validation, spatial temporal scales) analyzed. studies carried out Europe (55.5%), North America (22.3%), Asia (13.9%) South (8.3%). Soil Water Assessment Tool proved be most used model (45.95%). Herbicides modeled (71.4%), followed by insecticides (18.2%) (10.4%). main herbicides atrazine, metolachlor, isoproturon, glyphosate, acetochlor. Insecticides such as chlorpyrifos metaldehyde. Chlorothalonil, tebuconazole) widely investigated. Based published studies, it found that approaches for assessing are constantly evolving algorithms work well with diverse watershed conditions, management strategies, pesticide properties. Several reported concentrations exceeding ecotoxicological thresholds revealing water contamination agriculture urban areas is priority issue current global concern.

Assessing the effectiveness of potential best management practices for science-informed decision support at the watershed scale: The case of the Mar Menor coastal lagoon, Spain

The Science of The Total Environment, Journal Year: 2022, Volume and Issue: 859, P. 160144 - 160144

Published: Nov. 12, 2022

Coastal lagoons are ecosystems of high environmental importance but quite vulnerable to human activities. The continuous inflow pollutant loads can trigger negative impacts on the ecological status these water bodies, which is contrary European Green Deal. One example Mar Menor coastal lagoon in Spain, has experienced significant degradation recent years due excessive external nutrient input, especially from non-point source (NPS) pollution. one largest Mediterranean region and a site great socio-economic value. In this study, highly anthropogenic complex watershed Menor, known as Campo de Cartagena (1244 km2), was modelled with Soil Water Assessment Tool (SWAT) analyse potential options for recovery unique system. model used simulate several best management practices (BMP) proposed by regulations, such vegetative filter strips, shoreline buffers, contour farming, removal illegal agriculture, crop rotation management, waterway vegetation restoration, fertiliser greenhouse rainwater harvesting. Sixteen scenarios individual combined BMPs were analysed study. We found that, measures, strips farming most effective reduction: approximately 30 % total nitrogen (TN) 40 phosphorus (TP). Moreover, restoration showed highest sediment (S) reduction at 20 %. However, combination demonstrated clear synergistic effects, reducing S export 38 %, TN 67 TP 75 Selecting appropriate be implemented scale requires holistic approach considering effectiveness NPS pollution BMP implementation costs. Thus, we have way forward enabling science-informed decision-making when choosing strategies control contamination scale.
