Abstract
Remote Sensing provides us the quick and useful prelimary information on parameters controlling the occurrence and movement of Ground water like geology, lithology, structure, geomorphology, landuse/landcover, drainage etc. The present study , Nakkavagu catchment covering the total area of about 734 sq kms of Medak and Ranga Reddy District, Hyderabad and falling under the toposheet 56k/5 and 56k/6. Geologically the study area is underlain by Granites of Archean Age. Occurrence of ground water is resistricted mostly to zones of secondary porosity which developed due to the fractures, joint and weathering the area traverse the NW-SE lineaments.
The morphometric parameters of the area is determined to derive the general geomorphic characteristic of the basin Ground water potential units are Pediplain Shallow (PPS) are Pediplain Moderate (PPM), Inselberg(I), Piediment Inselberg Complex (PIC), Piedment(P) Residual Hill (RH) and Denudational Hill (DH). From the above geomorphic units the Pediplan Shallow the recharge is good and Ground water potential is more and in Pediplan Moderate the recharge is moderate to good and in other geomorphic units the recharge is poor and groundwater potential is very less.
