Sensitivity Analysis and Multi-Site Calibration of KRS Catchment using SWAT

Hydrological modelling offers itself as a crucial instrument for the management of water resources, it aids in understanding streamflow, sediments, and pollutants hydrographic basin. The KRS catchment Karnataka, India has undergone significant change driven by growth agricultural regions area, necessitating adoption tools studies that analyze environmental consequences primarily on surface resources. current study aim was to calibrate validate at multi sites using SWAT- CUP. Statistical performance coefficients attested model's capacity hydrological simulations this basin monthly time scale, Pbias, NSE R2 showing values good acceptable range calibration validation.
