Morphometric Analysis of the Banas River Basin Using the Geographical Information System, Rajasthan, India

Abstract

Geographical Information System techniques have been used for the identification of geomorphological features and analyzing the properties of the Banas River basin area in Rajasthan state, India. The Banas basin has covered an area of 51,779 km2. For this study, the Shuttle Radar Topographic Mission (SRTM) Digital Elevation Model (DEM) is used for evaluation of morphometric components like linear, areal and relief aspects with the help of ArcGIS software. Morphometric analysis of river basin was performed by determining the parameters like drainage area; gradient, relief; linear and aerial aspects. Watershed boundary, flow direction, flow accumulation, flow length, stream ordering have been prepared using hydrological tool and slope-aspect have been prepared using surface tool in ArcGIS. These results may be used in basin management development and hydrological studies.
