Abstract :

Extraction ofDrainagethrough the SRTM data using ArcGIStechnique to delineate the basin morphometry was attempted in this paper. This automated extraction tool will create the possible drainage pattern in the study area. After extracting the drainage, this was used to anlyse the morphometric parameterssuch as, stream network (Strahler’s), aspect, slope, DEM, drainage density, hill shade, and basin boundary.The slope generated is in degrees and the drainage density in square kilometer. The DEM gives an exact height variation over the terrain. This technique is very useful for those who work in the field of terrain analysis, hydrology, and watershed analysis as it is easy to use with a single click for the generation of a reliable database for morphometric analysis.
