Morphometric and Sub-Watershed Analysis of Taraka Watershed, H.D. Kote Taluk, Mysuru District, Karnataka, India using Remote Sensing and GIS Techniques

Abstract

The current research work is an attempt to study of drainage area covering 429 sqkms comprising of 10 sub-watersheds they are namely Heggadadevanakote, Budanuru, Kodasige, Yedenhundi, Sunkadakatte, Nagarahole, Muruganahalli, Heggadapura, Kalhalla, Sarathihole. The research area has strong structural control shows that the 10 sub-basins named as the normal category. Different parameters of morphometric were used, Arc-Info and Arc -View GIS software was used to analysis the morphometric parameters and drainage characteristics, Sub-basin have been delineated by drainage pattern. The drainage pattern suggesting very coarse to coarse texture and the density explains the texture of drainage is related to coarse as geomorphic development their late youth stage and values suggest that Form factor, Circulatory ratio, Sub-basins are circular to elongated in shape.
