Over the coming, the changing climate is likely to put pressure on the water resources of Ghataprabha sub-basin in southern India., This is the first attempt to assess the impact of climate change on surface water resources. Soil and Water Assessment Tool (SWAT) was used to carry out this study. Manual calibration and validation of the model was done for the period of 1995-2005 using observed discharge data. R2 and NSE were used as model evaluation criteria which showed the satisfactory model performance, with R2 and NSE of 0.69 and 0.60 during calibration and 0.61 and 0.50 during validation. To study the impact of climate change on hydrology of the sub-basin, data from HadRM3 regional climate model under A2 and B2 scenario for the period of 2070-2100 were used. Temperature analysis indicated the warming of the study area. Annual and monthly hydrological components are likely to increase for the selected climate change scenarios compared to the baseline scenario with the higher values corresponding to the A2 scenario.
