Land, water and soil are limited natural resources and their wide utilization with increasing population is a major area of concern. To mitigate the demand and supply gap between resources and ever increasing demand, it is of prime importance to conserve the natural resources with proper prioritization for its sustainable development. Morphometric analysis of a watershed provides a quantitative description of a drainage system. It is an important aspect of the watershed characterization. In this study, the morphometric analysis and prioritization of fourteen Sub-watersheds of watershed, situated in Mungeli block of Mungeli District Chhattisgarh State, India, was studied .comprises 978.345 km2 area and lies between 22° 5’5.12” N to 21°9’ 3.58”N latitude and 81°31’8.36” E to 81° 78’9.32” E longitude .The entire study region is divided into 14 sub-watersheds named as, 4G3F3b, 4G3F3c, 4G3F3d,4G3F3f, 4G3F3g, 4G3F3h, 4G3F3j, 4G3F3k, 4G3F3m, 4G3F3n, 4G3F3p, 4G3F3q, 4G3F3r and 4G3F3s. The drainage density of sub-watersheds varies between 0.8 to 1.13 km/km2 and low drainage density values of sub-watershed 4G3F3r indicates that it has highly resistant, impermeable subsoil material with dense vegetative cover and low relief. The elongation ratio varies from 0.62 to 0.68 which indicates high relief and steep ground slope. The high value of circularity ratio for 4G3F3p sub-watershed (0.742) indicates the late maturity stage of topography. The compound parameter values are calculated and the sub-watershed with lowest compound weight is given highest priority. The sub-watershed 4G3F3f has a minimum compound parameter value of 4.6 is likely to be subjected to maximum soil erosion and susceptible to natural hazards. Hence it should be provided with immediate soil conservation measures.
