Abstract:

The Hesaraghatta watershed is a part of Arkavathi river basin. Morphometric analysis has been carried out to understand the hydrological condition of the watershed. Geographic Information System has been used in the elevation of linear, aerial and relief aspects of the study area. The different morphological parameters like number of streams, stream frequency, stream length, and bifurcation ratio and aerial aspects drainage density (Dd) and drainage frequency (Df) of the basin reflect its hydrological response of the watershed. The geo-morphological analysis of the drainage network of a watershed gives information about the relationship between the surface runoff, infiltration of surface water and relative permeability of rocks in the study area. The Hesaraghatta watershed is the 6th order basin, dendritic pattern of drainage indicating moderate permeability and high runoff of the catchment. The watershed obeys Horton’s Law of relating linear and aerial aspects. The GIS study has brought out the relation between lithology, structure and morphometric characters.
