Abstract
The analysis of drainage morphometry performs manual and computerized delineation, which enables detailed morphometrical measures. Morphometric parameters derived from three different sources viz., Survey of India topographic map (1:50,000), SRTM (Shuttle Radar Topographic Mission-90 m) and DEM derived from ASTER (Advanced Space borne Thermal Emission and Reflection Radiometer-30 m) are evaluated to examine any difference within the results for the proper planning and management of the watersheds. Extracting drainage network from DEMs is mainly based on the flow of water from higher to lower elevation and steepest descent in a pixel. Common morphometric parameters are considered for analysis.
