Special Issue Information

Dear Colleagues,

I am pleased to announce a new Special Issue of Water entitled “The Impact of Climate Change and Land Use on Water Resources—an Issue of Environmental Global Safety, 2nd Edition”.

Water is the basic element for the optimal functioning of the environment at local, regional, and global levels, and the synchronous impacts of climate change, anthropogenic activities, rapid urbanization, desertification, and deforestation have led to imbalances and combined effects on the environment—greater pressure on water resources in arid areas or those affected by the increases in global temperatures or the local population.

The State of Food Security and Nutrition in the World 2023 stated that good quality water is so important in urban and peri-urban areas because almost 2.5 billion people consume street foods. Additionally, the policies and solutions for healthy diets in rural and urban areas are a significant issue. The damage to human health implies instability in social and economic systems and the need for greater financial resources.

Water scarcity and chemical pollution are key global food and environmental safety elements. Water availability is important in agriculture to maintain water resources and mitigate climate change impacts on land use and land cover. Good water resource management helps areas affected by desertification, dry landscapes, and droughts. Water resources are the base for regulating and supporting services, including cultural services.

This Special Issue aims to publish original research and review papers about climate change, land use, and land cover changes. Thus, papers with a theoretical background are welcomed, as are applied papers.

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 250 words) can be sent to the Editorial Office for assessment.

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.

A continuous integration framework and methodology for hydrological modeling is proposed that integrates model sensitivity analysis with real-time sensor tasking to prioritize data collection in regions and periods of high hydrological variability and drive model refinement. The Cahaba River Watershed in central Alabama serves as a case study to develop this approach. To this end, a benchmark Soil and Water Assessment Tool (SWAT) model (30 m DEM) was refined with high-resolution spatial datasets in QGIS, including 1 m DEMs, NLCD land cover, and SSURGO soil data. The refined model significantly enhanced subbasin delineation, increasing granularity from 8 to 99 subbasins, thereby improving representation of slope, runoff, and storage variability across heterogeneous landscapes. Sensitivity analyses were performed to evaluate the influence of DEM resolution and curve number (CN) perturbations on hydrologic responses, including retention, flow partitioning, and dominant flow direction. High-resolution DEMs (≤5 m) captured microtopographic features that strongly affect infiltration and surface runoff, while coarser DEMs (≥20 m) systematically underestimated retention and smoothed hydrologic gradients. The higher-resolution DEMs can be used to selectively improve the model at certain hotspots/areas of higher sensitivity. Localized flow simulations demonstrated that fine-scale terrain data substantially improve model realism, with up to 58% greater retention captured in 10 m DEMs compared to 30 m DEMs. The results confirm that aligning sensor placement and model refinement with spatially explicit sensitivity zones enhances both predictive accuracy and computational efficiency. The proposed continuous integration approach provides a scalable pathway for coupling high-resolution modeling with adaptive sensing in watershed management and supports future integration of real-time data assimilation for continuous model improvement.
