Abstract: Electrical resistivity method and RS & GIS techniques are very much useful in identification of potential aquifer zones for exploitation, management and recharge of groundwater. Vertical Electrical Soundings are conducted at 35 locations in Gurpur watershed using Schlumberger array. The thematic layers like porosity, transmissivity and hydraulic conductivity are prepared using electrical resistivity data. Total of 13 thematic layers are used for vector integration and identification of Groundwater Potential Zones (GWPZ). The numerical weights and ranks are assigned to the themes based on their relationship with groundwater. The findings shows that the depth to bedrock varies from 9.1 to 44.4 m and most of the mid land and low land region shows moderate to high depths of about 25 44 m. The GWPZ are classified into five classes namely, Very Good (?21.02 km2), Good (?231.35 km2), Moderate (?420.76 km2), Poor (?185.05 km2) and Very Poor (?19.56 km2). The Good and Moderate categories cover ?75% of total area. 2019, 2019 Informa UK Limited, trading as Taylor & Francis Group.
