Climate change would significantly affect many hydrologic systems, which in turn would affect the water availability, runoff, and the flow in rivers. The predicted intensification of hydrological cycle would change all of its constituents both in time and space domain. This is a long term phenomenon and the necessity is to understand the intensity of the effects on various aspects of water resources by way of scientific studies backed by the available field data. Therefore, in the present study, the impact of climate change on study area under different assumed plausible hypothetical scenarios has been studied. These scenarios were developed by increasing; temperature by 1, 2 and 30C; rainfall by 5, 10 and 15%; and then the combination of both. To carry out this analysis, Arc SWAT hydrological model has been investigated. It was found that slight change in climate may pose huge difference on the hydrological cycle and its component
