ABSTRACT
The need for groundwater development by locating suitable sites for construction of artificial recharge structures in the upper catchment area of Sali River Basin, Bankura District eastern India, has become inevitable of this chronically drought-prone area. In generally well-developed drainage pattern implies relatively low infiltration and relatively impervious materials while absence of surface drainage is the indication of high infiltration. High drainage density implies relatively high surface run-off. Due to the impervious nature of rock in this area, groundwater accumulates mainly within the weathered residuum. Consequently several thematic maps showing hydrogeomorphology (channel fills, buried pediment, surface water bodies) and other surface expressions (lineaments, land cover) of groundwater accumulation have been generated using topographical sheets and satellite imagery aided by field checks. All the thematic information has been dizitised and analysed using GIS and the resultant composite maps show suitable sites for artificial recharge structures.
