Reservoir sedimentation and catchment sediment yield in the Strines catchment, U.K.

Abstract

Rates of sedimentation and sediment yield have been calculated for the Strines catchment, UK. Estimates of original reservoir capacity are compared with measured capacities in 1956, 1993 and 1994 and sediment yields calculated using an extensive survey of the bulk densities of reservoir sediments. Rates of sedimentation and catchment erosion are low in global terms but relatively high for the United Kingdom. Rates of erosion and sedimentation would appear to have increased since 1956 and this is attributed to accelerated incision on the blanket peat moorlands in the upper parts of the catchment.
