The climate change, its impact assessment, modelling and simulating the groundwater level to climate change were made for the Ozat basin (3176.24 km2 area). The models developed for the sensitivity analysis shows that the wind speed is the most sensitive climatic parameter to the groundwater depletions followed by temperature, solar radiation and relative humidity. The model also indicated that the groundwater depletion is more sensitive to maximum temperature as compared to minimum temperature. The model of the groundwater level depletions response to mean temperature indicates that the increase/decrease in 1°C temperature, 1m/s in wind speed and 1 MJ/sq.m in solar radiation during winter season in Ozat basin can increase/decrease the 0.422m, 2.14m and 0.2325m groundwater level depletions respectively while increase/decrease of 1% in mean relative humidity can decrease/increase 0.154m groundwater depletions. The current trend of the climate change indicated that the groundwater depletions will be increasing 0.005 m per year among which the contribution of the current trend in the wind velocity, mean temperature, mean relative humidity and bright sunshine hours to groundwater depletions can be -0.00817m, 0.01216m, -0.00153m, and 0.002504m per year respectively.
