Abstract
The present study analyses the River Basin Delineation and Hydrological Response Units (HRUs) Analysis using Soil and Water Assessment Tool (SWAT) Model. Delineation of Rajasthan, India considering delineation of the River Basin plays a significant role in watercourse planning. The study focused to demonstrate the applicability of SWAT (Soil and Water Assessment Tool) - a model of residential scale to forecast the effect over a period of land, soil and water changes. Since hydrological models are essential tools for understanding the hydrological activity of river basins, hence are used for the management of the river basin. These models are capable of simulating the effect of various systems for soil and water conservation. Under this study the delineations of river basin was carried out by ArcGIS 10.2.1. Post delineation the land use map, the soil class map and the slope class map were superimposed to complete the river basin HRUs analysis on the delineated river basin map. The output of the study may help in water resource planning in the basin and to undertake appropriate preventive actions in areas that are vulnerable to erosion.
