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 Mcum day and total outflow into the aquifer is Mcum day. The outflow is more than the inflow by an amount of 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. Introduction The use of groundwater flow models is common in the field of environmental hydrogeology. Models have been applied to investigate a wide variety of hydro-geologic conditions. More recently groundwater models have been applied to predict the fate and transport of contaminants for risk evaluation purposes. Modeling is a best judgment .
