Abstract
For illustrating the stages of geomorphic development, area-elevation analysis and hypsometric study of watersheds are conventional approaches used frequently. The hypsometric integral assesses a watershed’s vulnerability to erosion and provides insights into its geological development stages. This integral is computed through empirical calculations based on a graphical representation of contour elevations. The Danro River watershed, a tributary of the North Koel River in the Jharkhand districts of Lohardaga, Latehar, Palamu, and Garhwa, has its hypsometric integral values evaluated in the current work. The watershed was divided into eleven sub-watersheds, and hypsometric analysis was performed on each of them using contour interval maps with the help of  geospatial techniques, primarily the GIS Software. The hypsometric integral values of the Danro watershed staggers between 0.50 and 0.48 to 0.50 for its eleven subwatersheds. The result shows that the watershed is in the mature or equilibrium stages of the erosional cycle of development.
