| dc.description.abstract | Watershed prioritization has become increasingly crucial for managing natural resources, especially the watersheds. A useful decision support tool to provide appropriate weights to different morphological attributes with lineage with soil erosion is required to identify environmentally stressed areas for the watershed resources. In the present study, an attempt has been made to delineate the Nayar watershed into Eastern Nayar and Western Nayar and further examining morphometric parameters of Eastern and Western Nayar watersheds. The morphometric parameters were quantified under the linear, areal, and relief heads for both the watersheds. The prioritization of sub-watersheds was done by the fuzzy analytic hierarchy process (FAHP). The study included nine morphometric parameters for forming a pairwise comparison matrix: relief, length of overland flow, drainage density, mean bifurcation ratio, stream frequency, texture ratio, elongation ratio, circulatory ratio, and form factor. The fuzzy analytic hierarchy process was employed for assigning the suitable weights to morphometric parameters and further these weights are normalized to assign the final ranks to the subwatershed. In Eastern Nayar, SW7 got the highest priority, and SW1 was categorized as the least priority. In Western Nayar, SW9 got the highest priority, and SW1 got the least priority after ranking. The results were validated by an index known as the consistency ratio, which depends on the matrix consistency index's size. The consistency ratio should be less than 10%, and after evaluating the consistency index of the present study, it came out to be 2%. | en_US |
