Fresh water is a scare resource. During recent decades, each and every anthropogenic activities such as domestic, agriculture and industries require large amount of surface water and ground water. It has been seen that globally water resources face extraordinary challenges but these are at highly in the world’s arid and semi-arid regions. In this region due to very little or no rainfall and lack of surface water, a ground water source becomes desired source for all activities. Identifying the potential region of ground water source become important for fulfilling the basic requirement of such region. In recent time the development of remote sensing approaches has helped in getting repetitive information of large area in short span of time. The satellite imageries of moderate to high resolution help scientist to delineate the ground water potential zone of the area with help of geospatial modeling approach. The present study employs the satellite imageries (Landsat Imageries, LISS III and Aster DEM) along with GIS technique to delineate the area having high potential of ground water source. The weighted overlay analysis is done using various thematic maps like, lineament density, geology, geomorphology, drainage density, Slope etc., to delineate the potential zones of ground water in water deficit district of Kalaburagi and Yadgir district of Karnataka.
