The effect of forestry drainage operations on upland sediment yields: A case study
Authors:M Robinson  K Blyth
Abstract:Forestry is generally considered to be a land use giving low sediment yields. However, in Britain most forestry is on land that requires extensive drainage, and it was found that the drainage of a small upland catchment resulted in sediment yields over the following five years equivalent to nearly half a century's load at pre-drainage rates. Subsequent sediment yields did not decline to pre-drainage levels, but remained about four times higher, as a result of erosion of the drains.
Keywords:Experimental catchment  Forestry  Forestry drainage  Sediment yields  Upland catchments
