摘要：Groundwater plays a fundamental role in shaping the economic and social health of many urban areas inIndia. Fast growing and emerging urban centres are demanding water to achieve higher growth rates. The exploration,assessment and management of ground water resource has become one of the key issues as ground water forms animportant component of the total water supply for drinking and irrigation purposes. The present study area is an attemptto delineate the groundwater potential zones in Bengaluru urban district, Karnataka, India using integrated approach ofRemote Sensing and GIS techniques. Various geological and geomorphological factors play a major role at differentlevels in the occurrence, movement and potential of ground water in hard rock terrain. Survey of India (SOI)Topographic maps and Resourcesat-2 (LISS IV FMX) satellite image are used to prepare various thematic layers suchas geology, geomorphology, drainage pattern, lineaments, soil and slope, which influence the occurrence, movement,yield and quality of groundwater. All these themes and their individual features were then assigned weights accordingto their relative importance in groundwater occurrence. The thematic layers will be integrated using ERDAS and ArcGIS software to identifying the overlay analysis & yield of the ground water potential zone map of the study area. Onthe basis of different geomorphic units, four categories of groundwater potential zones were delineated as (i) Good (ii)Moderate (iii) Poor and (iv) Very poor.
