Prioritization of the Sub-watersheds Through Morphometric Analysis in the Chinar Watershed

Morphometric parameters of a watershed encompass a range of measurable features and characteristics that play a vital role in understanding its hydrological behavior and guiding water resource management decisions. An attempt has been made to categorize the sub-watersheds through morphology of the Chinnar basin on the flood. Based on topography basin is divided into 29 sub-watersheds. Stream order, stream number, stream length, basin length, stream length ratio, mean stream length, bifurcation ratio, drainage area, perimeter, drainage density, stream frequency, texture ratio, elongation ratio, circularity ratio, form factor, compactness ratio, length of overland flow, ruggedness number, time of concentration, relief, relief ratio, relative relief, slope, infiltration number were evaluated for Chinnar. The highest and lowest elevations are 886 m and 50 m. Prioritization is done by the compound factor method. The sub-watershed is classified to the following categories of flood: very high, high, moderate, low, and very low. Sub-watershed 4,11,17,24 are very high-risk classes for flood and sub-watersheds 8,13,14 are very low-risk classes.
