Hydrogeomorphological units have been mapped using the IRS-1C, LISS III False Color Composite (FCC). The satellite images characteristics have been identified and assessed. The study area which belongs to the parts of Cauvery river basin around Manchanahalli, Karnataka state, India, exhibits diverse hydrogeomorphological conditions where the ground water regime is controlled mainly by topography and geology. The main hydrogeomorphic units found in the area are alluvial plain, Pedi plain, pediment, valley fill, meander scar and water bodies. Groundwater in this hard rock terrain with remnants of palaeochannels is multivariate in nature because of its relation to topography, depth and extent of weathered material overlying bed rock and interconnection of joints and faults.
