Today, water demand is increasing due to rapid urbanization, industrial growth and agricultural utilizations. Groundwater levels are decreasing due to all the above activities, decreasing of annual rainfall year to year due to climatic changes and increasing runoff. Hence, it is necessary to increase groundwater levels from the perspective of groundwater use for future demand. Keeping this in view, we have done a model study for a particular area. The study area consists part of the Hyderabad, Ranga Reddy, Yadadri-Bhuvanagiri and Medchal-Malkajgiri districts of Telangana, India. The area lies between 78°30′ and 78°45′ east longitude and 17°15′ and 17°30′ north latitude.          In the present study, we carried out delineation of groundwater prospect zones using IRS-ID PAN and LISS-III geocoded data on a 1:50000 scale. The information on structure, geomorphology and hydrology were generated and integrated to prepare a groundwater prospect map for the study area. GIS was used to prepare database on the above layers, analysis of relationship and integrated map preparation. The study area has complex geomorphology. On the basis of geomorphic characteristics, four categories of groundwater potential zones: Very good-good, good moderate, poor-nil and nil are delineated. In the final map, we have identified the areas with less groundwater potentials.
