SWAT modeling results identified priority locations for catchment management.
-
Total cost of the full implementation scenario was 111 million USD (about 12 billion rupees). The full
implementation scenario assumes all land management activities are done everywhere they are possible.
-
HRUs 1177 and 1145 had the highest average annual change in sediment yield.
-
SALT was the recommended activity for all top-ranked watersheds with the highest potential change in sediment
yield from full implementation.
-
Roughly half of the full implementation budget, or $53M USD, would be spent on SALT before reforestation or
conservation agriculture (on lower sloping areas) become the more cost-effective alternative.
-
Most areas with highest modeled reduction in sediment load are outside of the area of immediate impact of the
Kaligandaki facility.
