Water is an essential source to people and the largest available source of freshwater lies underground. Groundwater is an important source of water supply throughout the world. With the increasing demand of groundwater for various activities, the groundwater potential quickly declines. In order to prevent the aquifers from drastic depletion, the groundwater recharge is very essential. This study attempts to identify the favorable areas for groundwater recharge zones and to suggest the suitable recharge structures to augment the aquifer system of the study area using Remote Sensing (RS) and Geographical Information System (GIS). The various thematic maps, such as Geomorphology, Geology and lineaments, Soil, Slope, Land use/Land cover, Drainage, Runoff, Depth to weathered zone, Groundwater level fluctuation, and Water quality are taken for the analysis. The favorable areas for groundwater recharge have to be categorized as highly favorable, moderately favorable, less favorable, and poor.
