An Integrated Study to Assess the Groundwater Potential Zone Using Geospatial Tool in Salem District, South India

Abstract

The present study reveals that the geospatial tool for delineating the groundwater potential zone in Salem district, Tamil Nadu, South India is quite useful. Assessing the ground water potential zone is very important for protecting and managing the groundwater system. The study area mostly consists of hard rock terrain especially in charnockite and fissile hornblende biotite Gneiss. There are four thematic layers were considered in this present study such as geology, geomorphology, drainage density, and lineament density. These four thematic layers were integrated for identify the groundwater potential zone. Therefore, five different groundwater potential zones were identified, which are very good, good, moderate, poor and very poor. These groundwater potential zones are covered by an area of 346 km2 , 2932 km2 , 666 km2 , 880 km2 and 406 km2 respectively. Finally, the present study concluded that the remote sensing and GIS is very fruitful and useful for the assessing the groundwater potential zones.
