The long鄄term information on runoff and soil loss in catchments treated with soil conservation structures,espe鄄
cially gully plugging in the highest order gullies showed that the planted vegetation in Shiwaliks was not as effec鄄

structures installed in the highest order gullies are effective only during the initial years and later on these cause

due to unabated runoff and soil loss in the gully network. It results in increased erosivity of the runoff water resul鄄
