This study has presented comprehensive modelling environment for SWAT including manual calibration and validation. The goal of this study is to estimate the surface runoff of a selected watershed at ungauged stations using Soil and Water Assessment Tool (SWAT) model. To examine and demonstrate how it functions, Shimsha river basin was used in the present study. The various inputs like Digital Elevation model (DEM), Land use & Land cover (LU/LC) map, soil map, slope map, weather data, etc., were used in SWAT model to simulate runoff values on daily and monthly basis for the period 2000-2020. The calibration and validation of the software was carried out for a period 2011-2015 and 2016-2020 respectively. The simulated values were compared with the observed discharge values of Igloor dam. The model behaved well during calibration with an R2 value of 0.6613 and during validation 0.6469. The study demonstrates the application of SWAT model in generating runoff values at the required ungauged stations which helps in implementing effective management practices.
