The geomorphological property of the watershed plays a vital role in times of crisis in solving hydrological problems, which otherwise cannot be carried out due to inadequate data in some ungauged watersheds. In the current study, the 18 sub-watersheds of Singipuram are classified based on their vulnerability to soil erosion by morphometrical analysis with subsequent prioritization. Singipuram is a sub-watershed pertaining to the Vellar basin of Tamil Nadu, India. The morphometric properties selected to prioritize the sub-watersheds are the bifurcation ratio, circulatory ratio, compactness ratio, elongation ratio, drainage density, form factor, stream frequency, stream length, stream order, and texture ratio. Post morphometric analysis, the quantity compound parameter value was computed, after which the priority ordering of 18 mini-watersheds was performed. The mini-watershed 10 is subjected to the highest erosion as it has the least compound parameter value of 8.3. Hence, top priority while adopting soil conservation measures has to be provided for this mini watershed.
