Abstract :

Remote Sensing and Geographic Information System techniques are successfully being second-hand in recent times as a significant device in influential the quantitative explanation of morphometry of a basin. This technique characterizes very high precision of mapping and dimension of the morphometric investigation. The mean of the present learn is consequently to evaluate the GIS-based morphometric activities of the  Dumar Kocha watershed of Angara block in Ranchi district, Jharkhand. Morphometric factor detail preserves assist in the enhanced supervision of the watershed. This study aimed to evaluate morphometric characteristics of the Dumar Kocha watershed for its prioritization towards planning and development. The watershed is located in Ranchi district close to Ranchi, the state capital of Jharkhand state in India and lies between 23º21’35”N to 23º26’10”N latitudes and 85º30’30”E to 85º36’38”E longitudes. Methods of Strahler, Horton, and Schuman were useful which helped in assessing the fluvial character of the watershed. The watersheds of the study are found is third order. The various values of a different parameter such as drainage density vis of 1.528 km/km2, bifurcation ratio ranging from 1.736 to 3, the circular ratio are 0.712, relief ratio is 24.038, these values gives a measurement of the basin condition which can be utilized for proper planning of the watershed development.
