SWAT is the Soil and Water Assessment Tool, a river basin model developed originally by the USDA Agricultural Research Service (ARS) and Texas A&M University that is currently one of the world’s leading spatially distributed hydrological models. SWAT is a continuous time model that operates at sub-basin and watershed scale to predict long-term impacts from management, agricultural practices, pollution, and environmental changes. SWAT can analyze the impacts of climate change on hydrology with stream flow simulations. In this study, an overview of SWAT hydrological model is presented which includes Introduction and background of swat model, Historical Development, Theoretical Description of SWAT model, Key process and algorithm used in SWAT, Important SWAT modules and resources, Capabilities, SWAT Components, Strengths and limitations, General applications of the SWAT model are discussed. This study will be helpful in developing an insight to the growing application of hydrological models.
