Abstract: The hydrology of Groundwater movement depends upon the physical and chemical characteristics of both soil and water. These features must be measured and related to subsurface storage space and water dynamics, so as to decide the feasibility of a site for recharge and to select suitable methods and systems of recharge. So that water may be efficiently stored underground and then used independently or conjunctively with releases from surface storage reservoirs. In irrigation tanks, heavy siltation is the main limiting factor for percolation efficiency. The study of geology or soil characteristics in the tank bed for the infiltration recharging system is rather more important. At the same time Hydraulic conductivity is also very important parameter. Therefore, estimates of initial infiltration rates are must for estimating hydraulic conductivities of infiltration system in irrigation tanks. In this study, it has been planned to assess the recharge behavior of the tank bed in order to locate the highly permeable zone for desilting by conducting geophysical survey to demarcate the location for infiltration test. The results obtained from the infiltration test were correlated with the soil properties. From the analysis, the recharge characteristics of the tank bed were assessed.
