This study presents the application of analytical hierarchical process based multicriteria
decision support tool for prioritization of critical areas of Andhiyarkhore
catchment for soil and water conservation (SWC) and management works. Fourteen
different soil and water management parameters were calculated for each of the fiftyone
delineated watersheds in Andhiyarkhore catchment. The normalized values of
these parameters were arranged in a comparison matrix to assess corresponding
weights to prioritize the watersheds. The average annual soil loss had highest weight of
0.23 and elongation ratio the minimum weight of 0.01 at 9.66% consistency ratio (within
10% limit). The highest priority for the SWC measures was obtained for SW-7 watershed
and lowest for SW-47 watershed. The average annual groundwater recharge estimated
in the Andhiyarkhore catchment was only 4.13% of average annual rainfall, which
envisages need for SWC works in Andhiyarkhore catchment. Nine watersheds having
325.7 km2 of the catchment have very high priority for undertaking SWC works.
