Abstract

Remote sensing technique integrated with GIS is found to be very effective tool for identification of potential zones for groundwater exploration. Hydro geomorphological mapping coupled with hydrogeological investigations and structure/lineaments have been proved to be effective to locate groundwater potential zones. Identifying a good site for groundwater exploration in a rugged terrain is a challenging task. In hard rocks, groundwater occurs in secondary porosity developed due to weathering, fracturing, faulting, etc., which is highly variable within a short distance. In such situations topographic, hydrogeological and geomorphological features provide useful clues for the selection of suitable site for groundwater exploration and hence integration with GIS and Remote sensing technique can be a most promising method. Remote sensing and Geographical Information System is currently used in the project to analysis the drainage basin and for identification of ground water potential zones on integration of various thematic maps. Based on the available information and the geophysical investigations it is concluded that Stream order of basin indicates that the basin is sixth order basin with dendritic type of drainage pattern with homogeneous nature and the number of streams usually decreases as the stream order increases. The result of aerial aspect shows the texture of drainage is moderate. The ground water potential zones in the study area are classified into poor to medium, medium, medium to high and high respectively. The good potential zones are confined to in and around the lower stream order. Various artificial ground water recharging structures have been provided near 2nd and 3rd stream order for augmentation of water resources in the study area.
