摘要:Water is the most precious gift of nature, most crucial for sustaining life and is required in almost all the activities of living beings. The scarcity of water increases day by day due to the rapid development of urbanization, natural calamity etc. This paper mainly deals with the integrated approach of Remote sensing and Geographical Information System (GIS) to delineate groundwater potential zones of Bengaluru urban District, Karnataka. The various thematic maps generated for delineating groundwater potential zones are geomorphology, geology, lineament density, drainage density, slope ,NDVI, and landuse/landcover (LULC) were generated using the resource sat (IRS P6 LISS IV FMX)data and survey of India (SOI) toposheets of scale 1:50000. All these themes and their individual features were then assigned weights according to their relative importance in groundwater occurrence and the corresponding normalized weights were obtained based on the Composite Suitability Index (CSI) “importance matrix” has been calculated for each composite unit by multiplying weightages with rank of each parameter and summing up the values of all the parameters. The thematic layers will be integrated using ARCGIS-10 software to identifying the overlay analysis & yield of the ground water potential zone map of the study area. From the overlay analyses of landuse Pattern ,Thus the different ground water potential zones are identified in to 5 classes namely ‘good’, ‘good-moderate’, ’moderate’ , ‘moderate-poor’ and ‘poor
