Abstract

The study of drainage morphometric analysis and data for preparing Digital Elevation of Model (DEM) flow direction, flow accumulation, contour aspect and slope maps. Geographic Information System was used in evaluation of linear, areal and relief aspects of morphometric parameters. The drainage patterns of dendritic basin, which includes highest stream order up to 5 and the area covers 441sqkm.The Byramanagala watershed area is major part of Kengeri. In this paper is an attempt to evaluate the groundwater system of Byramangala Reservoir watershed area, Kengeri, Bangalore Urban district, Karnataka. Hydrogeological investigations require an integrated approach. No systematic hydrogeological investigations have been conducted so far, though groundwater is replenish able natural resources, when withdrawals exceed the limits of dynamic recharge, it will cause irreversible damages. As in nature, South India is a hard rock terrain. In recent years, bore wells for agricultural purposes have been drilled on a massive scale by the farmers without carving for minimum interference distance to be maintained between the extraction structures. Thereby, groundwater levels are drastically affected. To reach this goal an integrated hydro geological study in the whole area has not been attempted so far.

Keywords: Morphometric analysis, Massive scale, DEM, hydrogeological etc.
