Abstract

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