Effect of soil conservation measures on sediment yield at Chattar Kalas (AJK)

ABSTRACT
A study was conducted to evaluate the effect of soil conservation measures on sediment yield in three catchments at Chattar Kalas, Azad Jammu and Kashmir. One catchment was treated with contour bunds for surface erosion control and check dams for channel erosion control; second catchment having sparce natural vegetation was treated only for channel erosion control with check dams and the third catchment was not treated at all. All catchments were provided with sediment monitoring structures. Four years sediment yield data showed that the erosion rate can be reduced to almost half by adopting technical control measures. The average sediment yield from the catchments treated with technical control measures (both for surface and channel erosion control )and the catchment treated only for channel erosion control, was 1.00 and 2.0 tonnes/ha/year respectively. On the other hand, the average sediment yield from the untreated catchment was 3.6 tonnes /ha/year.
