Abstract
This article describes general hydrogeological set for the Solani watershed. Satellite imagery obtained from Landsat-7 ETM+ has been analysed to prepare the groundwater prospects map. By using SAR interferometry techniques, paleochannels, geomorphic units, lineaments, could be identified and delineated at a reasonable level of accuracy. In this study the following aspects have been covered: drainage map, geology, geomorphology, depth of water table map, water table contour map, EC (electric conductivity) distribution map etc. From these thematic maps ground water prospects map, has been prepared. As seen in these maps, the depth of water table in this area ranges from 2 m from ground level to more than 100 m; the EC of ground water varies from 284 to 2,000 μS/cm. Five different prospect zones: excellent, good, moderate, low, and runoff zone are identified according to the integration of thematic maps.
