Hydrological modeling through soil and water assessment toolin a climate change perspective a brief review

Accounting the impacts of climate change on watersheds and water availability, development of adaptive strategies for the exacerbating circumstances is of highest concern. But in order to develop coping abilities, precise quantification of climate change effects and accurate future predictions are necessary. Hydrological modeling is a common practice to fulfill this purpose. This paper presents a brief review of concepts and applications for Soil and Water Assessment Tool (SWAT) in a perspective of changing climate scenarios. Being a physical model, SWAT can be applied to simulate under varying spatio-temporal dimensions. The applicability and performance of hydrological modeling through SWAT across various parts of the globe is presented. Based on the prior studies, the likely benefits and limitations of the model are also discussed. This study will be helpful in developing an insight to the growing application of hydrological models for assessing climate change.
