Watershed prioritization based on morphometric characteristics using integrated RS-GIS and MCDM technique: A case of Chathe watershed

Author(s):
Sewak Ram, RC Nayak and Manoj Dutta
Abstract:
Chathe watershed is divided into seven sub-watersheds that are prioritized for soil and water conservation based on linear, areal, and relief features. Individual aspects as well as an integrated index created by the AHP and TOPSIS were used to priorities sub-watersheds from the ALOS-PALSAR DEM. The final result revealed that WS2 was the most prioritized sub-watershed with a high priority rating, with WS4 and WS7 following closely behind. WS3 and WS6 are on the moderate level, while WS1 and WS5 are in the low level. Higher linear and relief characteristics, as well as higher drainage density and stream frequency in an elongated basin with lower infiltration, were found to be more vulnerable. This work will assist the research community in taking necessary soil and water conservation measures in that area in future.
