Fields of Application of SWAT Hydrological Model—A Review

Soil and Water Assessment Tool (SWAT) is a widely used model for runoff, non-point source pollution, other complex hydrological processes under changing environments (groundwater flow, evapotranspiration, snow melting, etc.). This paper reviews the key characteristics applications of SWAT. Since its inception in 1990s, there has been significant increase number articles related to SWAT model. In last 10 years, almost reached 4000. The range varies between small large scales; however, watershed modelling dominates North America Asia. Moreover, prevailing impacts environment, which global problem. shortcoming vast quantity data necessary run generate accurate reliable results, not accessible some regions world. Apart from accessibility, it several advantages, including continuous development, results slew new interfaces tools supporting Additionally, can simulate human activity agricultural measures adapt circumstances situations. article emphasizes weaknesses strengths application on climate environment.
