Applications of SWAT (soil and water assessment tool) model: A systematic review

Abstract

Two important resources for human existence on the earth are land and water. It demands adequate management to obtain maximum utilization. The use of hydrological models for management of watershed resources is becoming more prevalent in decision-making processes. SWAT (Soil and Water Assessment Tool) is a promising model for simulating runoff, sediment and nutrient transport and erosion under various management scenarios. This work provides an overview of the advancements made in hydrological modeling using SWAT in previous studies. Numerous hydrological phenomena have been evaluated across a variety of study areas with the use of the SWAT model. Many investigations, including those on streamflow and land use planning, have employed the SWAT model with extremely effective implementation, as demonstrated by the reviews examined in this study. Thus, to review the studies conducted by different researcher’s using the SWAT is the primary objective of this paper. This research focuses on the literature on SWAT model applications in India.
