Since the 1990s, substantial advancements in SWAT, including parameterization, calibration, and uncertainty analysis, have made it the leading model for runoff, non-point source pollution, and complex hydrological processes like groundwater flow and snow melting across various scales. SWAT's flexibility and comprehensive simulation modules, along with strong model support and open-source code, make it highly effective in addressing diverse water management issues. Among other values, SWAT can outstanding tool for understanding processes in the soil profile. While other prominent hydrological models have emerged, this special issue focuses on contributions using SWAT to highlight its strengths and weaknesses, aiming to inform future developments within the computational hydrology community. Climate change conditions drastically affect water balance components having far-reaching consequences on the environment and agriculture. We want to focus on these processes in hydrological modeling.

Many articles on the application of the SWAT model have been published in scientific journals. In this special issue, we would like to give an overview of the SWAT model application with emphasis on its application on the change conditions. The significance of climate change impacts on hydrological processes became more pronounced in this century, with the tendency of increasing and having tremendous impacts on water balance and water quality as well.

This Research Topic welcomes submissions addressing the following key issues, but are not limited to:

• water balance in the climate change conditions
• watershed resilience on climate change
• hydrologic testing at a wide range of watershed scales;
• transport of pollutants in lowland watersheds;
• data input and routing method effects on sediment transport;
• development and testing of new modules and model algorithms;
• scenario analysis
