Watershed prioritization plays a vital role in watershed conservation and management. Morphometric analysis has been commonly used for the prioritization of watersheds. In this present study, prioritization of watershed based on morphometric parameters has been performed for the Tawi catchment of Jammu, J and K. Various morphometric parameters have been computed in the present study using the GIS technique for each sub-watershed including area, perimeter, stream order, stream length, stream number and elevation, which were obtained from the digital elevation model coverage of the drainage network map. Whereas the other parameters like bifurcation ratio, circulatory ratio, drainage density, stream frequency, elongation ratio, texture ratio, form factor and compactness ratio were calculated by using their standard formulae. From these parameters, compound values have been calculated by assigning their respective relation with erodibility, vulnerability and structural disturbances. Based on morphometric analysis, the sub-watersheds have been categorized into high, medium and low in terms of priority for the management and conservation of natural resources.
