- •
We found increasing grassland, decreasing bare land and sandy area within 1990–2006.
- •
The catchment has 502 check dams with total volume of 571 Mm3 built by 2009.
- •
Land use changes and check dams in 2006 reduced the sediment yield nearly by 80%.
- •
Check dams are efficient but not sustainable measures for sediment control.
