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.
Highlights
Remote sensing application is wide in all fields especially on aspects of surface covering a large area
Arc GIS maps will be better tool to understand the particular area under study of morphometry on watershed expressed as quantitative analysis description of the drainage pattern in watershed
Stream order The easiest, simplest and widely used numbering is the first tributaries rank of 1 first-order and followed second-order was defined under junction of two first-order streams (Strahler, 1964)
Summary
Remote sensing application is wide in all fields especially on aspects of surface covering a large area. This paper will explain a detail hydrological aspects study area taraka watershed at district Mysore, Karnataka covers 429 km. Arc GIS maps will be better tool to understand the particular area under study of morphometry on watershed expressed as quantitative analysis description of the drainage pattern in watershed. Fig. 3a: Stream order at the area a) Study Area The Taraka water basin is a part of the river Cauvery basin in the H D KoteTaluk, Mysore District of Karnataka. It is located between 12o00’ to 12o15’ North latitudes and 76o5’ to 76o25’ East longitudes. Drainage pattern of study area was prepared by topo sheets, the 5.8 m spatial resolution and interpretation keys are tone, pattern, texture, and association
