Special Issue Information

Dear Colleagues,

This Special Issue delves into the critical nexus of hydrological and ecological interactions within watersheds, seeking to advance our understanding and management capabilities through sophisticated modeling approaches. The convergence of enhanced computational power, rich datasets, and refined understanding of processes has catalyzed a new era of watershed modeling, capable of capturing the intricate interplay between biogeochemical cycles, ecohydrology, erosion, anthropogenic influences, and atmospheric drivers.

We invite submissions that explore ecohydrological processes at the watershed scale, particularly focusing on the application of physics-based, data-driven, or hybrid models. This Special Issue will highlight research that quantifies the impacts of land cover and climate change, alongside human infrastructure, on watershed hydrology, and water quality, encompassing nutrients, sediment, bacteria, and emerging contaminants. We encourage innovative modeling efforts that improve predictions of both traditional and emerging contaminants; integrate novel data sources, including remote sensing and qualitative data; enhance model structure and leverage advanced computational technologies; and model coupled surface and subsurface flow processes. This Special Issue aims to showcase cutting-edge research that bridges the gap between theoretical modeling and practical watershed management, fostering a deeper comprehension of these complex systems.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Water is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

To ensure water source security and sustainability of the national major strategic project “South-to-North Water Diversion”, this study aims to evaluate the spatio-temporal evolution characteristics of the ecosystem service value (ESV) in its water source area from 2002 to 2022. This study reveals its changing trends and main influencing factors, and thereby provides scientific support for the ecological protection and management of the water source area. Quantitative assessment of the ESV of the region was carried out using the Equivalence Factor Method (EFM), aiming to provide scientific support for ecological protection and resource management decision-making. In the past 20 years, the ESV has shown an upward trend year by year, increasing by 96%. The regions with the highest ESV were Garzê Prefecture and Aba Prefecture, which increased by 130.3% and 60.6%, respectively. The ESV of Xinlong county, Danba county, Rangtang county, and Daofu county increased 4.8 times, 1.5 times, 12.5 times, and 8.9 times, respectively. In the last two decades, arable land has decreased by 91%, while the proportions of bare land and water have decreased by 84% and 91%, respectively. Grassland had the largest proportion. Forests and grasslands, vital for climate regulation, water cycle management, and biodiversity conservation, have expanded by 74% and 43%, respectively. It can be seen from Moran’s I index values that the dataset as a whole showed a slight positive spatial autocorrelation, which increased from −0.041396 to 0.046377. This study reveals the changing trends in ESV and the main influencing factors, and thereby provides scientific support for the ecological protection and management of the water source area.
