Groundwater is an important major natural source of freshwater in the world. Groundwater recharge is an important part of the natural water cycle. Recharge estimates are needed for water balance studies, water supply engineering and water resource purposes. Visual model flow model was employed to simulate the ground water flow and to estimate the recharge for Vadachitur watershed located in Kinathukadavu block of Coimbatore district. Estimation of the hydraulic conductivity, specific yield and specific storage were assigned for each layer of the model based on the hydrological formation and pumping tests. The simulation results show that total inflow into the aquifer is 7.965 Mcum/day and total outflow into the aquifer is 7.954 Mcum/day. The outflow is more than the inflow by an amount of 0.0011 Mcum/day for the period of 365 days. It is recommended to construct suitable recharge structures r to improve the recharge rate for the Vadachitur watershed for sustainable ground water management.
