The global warming has changed the climate worldwide. However, the nature and magnitude of the climate change vary in space and time. Its impacts also vary in space as well as time. The climate change will have different impacts in different places on rainfall amount, its intensity, frequency, rainy days, evapo-transpiration etc. These rainfall characteristics and evapo-transpiration ultimately impact on runoff and groundwater recharge also. Therefore, the location specific studies on basin scale are required to assess the impact of climate change on rainfall, runoff and groundwater...
