The water availability is limited, however demand of water is increasing many fold due to expansion of agriculture, growing population, rapid industrialization and economic development in India. Available water resources need to be managed properly to meet increasing demands of water. In this study, different hydrological processes as surface runoff, evapotranspiration and soil moisture were modeled to assess the groundwater recharge in a small watershed located in semi-arid region of Rajasthan, India. The daily potential and actual groundwater recharge in the watershed were estimated using HYDRUS-1D, an unsaturated flow model and Water Table Fluctuation (WTF) method, respectively. It was observed that the mean cumulative potential groundwater recharge in the watershed was found to be 3.24 cm (6.91 per cent of average annual precipitation of the region). The average actual recharge estimated by WTF method was found to be 8.3 per cent of average annual precipitation which was comparable with the HYDRUS-1D model.
