Abstract
Cartosat-1 data helps to generate digital elevation model (DEM) with 2.5 m ground sampling distance (GSD). It can provide details topographic and morphometric parameters, thus been applied to a sub watershed. The drainage basin is fundamental geomorphic unit of land and all flow of surface is governed by its properties. In this paper several drainage basin characteristics are analyzed scientifically with the use of Cartosat-1 data in the ERDAS and ArcGIS software tools. The analysis reveals that subwatershed assumes pear shaped characteristics, high degree of integration, high infiltration, flatter peak of flow for longer duration and easy for flood control. Morphometric parameters can help in decision making process for water resources management. By understanding the morphometric parameters, appropriate attention can be paid towards soil conservation and flood control measures in the subwatershed.
