Abstract

In the present study morphometric analysis of Arkavathi watershed is based on remote sensing and geographic information systems. The morphometric parameters are calculated with Carto sat DEM using Arc GIS 10.3 extension and Arc Hydrology tool in order to characterize it quantitatively. The current study involved determining the linear, aerial, and relief dimensions of the eight sub-watersheds for soil and water planning and management of the watershed. The watershed characterizes to have a dendritic pattern of drainage which has a medium stream frequency and moderate drainage density. Circularity ratio and form factor values indicate that sub watersheds are more or less elongated. The Length of the overland flow has a high value with gentle slopes and long flow paths. Understanding the procedures and methods of various morphometric factors can thus be used to prioritize watersheds for management, rainwater collection, and conservation planning.
