28-Remote sensing studies for groundwater investigations in part of Dhasan river basin (Uttar Pradesh)

Abstract

The study area lies in Bundelkhand Granitic complex, which is overlain by unconsolidated alluvial sediments. Here an attempt is made to employ Landsat-4 imagery (1: 250,000)and Thematic-Mapper Data of Landsat-5 (1:62,500) for the hydrogeological studies in the area. Based on the tonal expressions, geomorphic features, drainage patterns, lithologic characters and structural features, the hydrogeological conditions in the area were evaluated. On the basis of above studies, potential water bearing zones have been demarcated for groundwater exploration. Geophysical studies were undertaken in the zones indicated to be promising from the above studies. One site has already been drilled and proved successful and the results of other sites are expected to be encouraging.
