Morphometric analysis of Bembla sub-basin in Maharashtra using Remote Sensing and GIS based techniques

Abstract

The present study is an attempt to show the use of remote sensing and GIS based techniques in analysis and management of water resources. Morphometric analysis involves studying the linear, aerial and relief aspects of a basin to better understand the properties and geomorphological controls of the basin. The Bembla river is a VIIth order stream and a tributary of Wardha River. the Bembla sub-basin covers an area of 3040 km². Morphometric analysis of the basin indicates that the the basin is less elongated. The sub-basin has low relief and coarse drainage. The basin overlies relatively impermeable stratum with low peak floods and high storage capacity. The study was undertaken using a SRTM data coupled with ArcGIS tools to process the data which helped in better understanding of the relationship between the topography and the drainage network.
