Because of its simplicity, the sediment delivery ratio (SDR), based on the ratio of the sediment yield (Y) and the gross erosion (E) in the basin, is widely used to estimate sediment production in watersheds. Since Y and E are complexly linked, several SDR equations were developed. Financial compensation programs resulting from sedimentation abatement, such as the Water Provider Program, often require the estimation of reduction of the downstream sediment yield as a function of erosion reduction upstream. This study […]
