In our country a considerable part of the Agricultural production depends upon the availability of groundwater. So, exploration of groundwater has got an importance. Groundwater occurrence being a sub-surface phenomenon, its identification and location is based on direct or indirect analysis. Directly it can be observed by terrain features like geological and geomorphic features and their hydrologic characters. In modern techniques GIS tool, remote sensing data were used to prepare and analyse digital layers of lithology, geological structures, drainage and topography to detect the most important promising sites for groundwater exploration. An integrated approach including studies of lithology, drainage and slope have been taken up using GIS techniques. A separate map of existing groundwater levels is integrated with the generated maps to calculate the zones of groundwater. A case study of Beemunipadu, Guladurthi, Kampamalla, Pottipadu of Koilakuntla mandal of Kurnool District is made to detect the ground water zones by using GIS and Remote Sensing applications. The study showed that Remote Sensing and GIS provided efficient tools for mapping promising sites for groundwater exploration. However, the data of groundwater wells would contribute to refining the final locations of most promising sites.
