Groundwater potential and recharge zone mapping for Namakkal town using RS & GIS

Abstract

Groundwater is the main source for domestic, industrial and agricultural requirements. Hence the groundwater infected with the aid of anthropogenic activities. Due to the depletion of ground water wells natural recharge will be insufficient to fulfill the actual requirement. The usage of remote sensing and geographic information system (GIS) it's far viable to take quantity of various thematic maps of the identical region and overlay them on top of each other to form a trendy incorporated layer.
