The water budget is an important phenomenon driving all other processes in a watershed. Climate is the main driver responsible for regulating the water budget process and planning of water resources. Soil and Water Assessment Tool (SWAT) is a widely used hydrological model, which has been used in the study to understand the role of climate parameters on water budget components. The water budget of the baseline period (1990-2004) was calculated .Model was simulated for three global SRES precipitation and temperature scenarios (A2, B1 and A1B) for three different time periods (2010-2024;...
