Abstract: Hydrological analysis and for the integrated development of the watershed, it is essential to do geomorphometric analysis. A comprehensive study of drainage pattern, topography, and most essential erosion status can be analyzed through morphometric analysis. Prioritization of sub-watersheds according to the capacity of the water table of Nashik district watershed was evaluated by linear, aerial and relief aspects. The morphometric analysis has been used for the prioritization of seven sub-watersheds of the Godavari river basin in the Nashik district, Maharashtra. Using the Digital Elevation Model, the sub-watersheds were delineated in ArcMap 10.4 and also few extraction works were done in Erdas Imagine. Drains and their corresponding characteristics including stream length, stream order, stream frequency, circulatory ratio, texture ratio, compactness coefficient, elongation ratio, form factor, drainage density, bifurcation ratio is analyzed and their value has evaluated for each sub-watershed by using the Remotely Sensed-data and geospatial techniques. Finally based on morphometric behavior the priority has been given to each sub-watershed & rank has assigned to them, the most sensitive sub-watershed is identified. The reveled analysis says stream order ranges from 1 to 6. The overall stream segments of all order are 1,115 in the watershed. On the account of morphometric analysis prioritization of watershed is done. Resulting prioritization rank assigned to each watershed based upon the evaluated compound parameter given to them. Those Sub-watersheds having least compound parameter value has assigned the highest priority. Further, sub watersheds accordingly categorized into three type i.e. high (3.4-3.8), medium (4.0-4.2) and low (4.4) priority based on their maximum priority score (4.5) and minimum score (3.4).
