The growing demand and competition for water from domestic, industrial and agricultural sectors reached utmost limit. Drainage basins, catchments, and sub-catchments are the hydrological units ideally suited for planning of conservation of land and water resources. GIS techniques are useful for analysis of morphometric properties of any watershad. Morphometric aspects: linear, relief, and areal aspects of Kolavadi sub-watershed of Upper Nira basin were analyzed using spatial tools and arc-hydro tool in Arc GIS 10.3. The bifurcation ratio (2 to 4.5) indicates structural disturbances and mature topography with higher degree of drainage integration. This watershed shows less elongated shape with low relief, moderate to gentle slope, moderate drainage density and highly prone to soil erosion. Techniques used in study and results are useful for planning and monitoring the sub-watersheds for sustainable development.
Morphometric aspects (linear, relief, and areal) of Kolavadi sub-watershed of Upper Nira basin were analysed using spatial tools and arc-hydro tool in GIS software.
The higher (2 to 4.5) value of bifurcation ratio shows mature topography with structural disturbances and higher degree of drainage integration.
The sub-watershed shows less elongated shape.
The drainage density and stream frequency highlight moderately drained drainage basin.
Relief ratio (0.07) indicates low relief and moderate to gentle slope.
The ruggedness number (1.27) shows higher soil erosion.
