    Erosion and Sediment Delivery Introduction Soil erosion consists of a series of natural processes that move earth and rock material. The land surface is worn ... Sediment delivery ratio (SDR) is defined as the sediment yield from an area divided by the gross erosion of that same area. SDR is expressed as a percent and represents the efficiency ...File Size: 314KB

PREDICTING SEDIMENT DELIVERY RATIO IN

    http://www.iwr.msu.edu/rusle/sdr/sag-sdr.htm
    A watershed with steep slopes has a higher sediment delivery ratio than a watershed with flat and wide valleys. In order to estimate sediment delivery ratios, the size of the area of interest should also be defined. In general, the larger the area size, the lower the sediment delivery ratio. STUDY AREA

    Each pond or basin in the series removes a greater proportion of the large-size particles remaining in suspension than the very fine-size particles, hence, enriching the proportion of fine-size particles and increasing the sediment-delivery ratio.A general method for accounting for the change in sediment-particle size, external to the RUSLE program, is provided in Toy and Foster, eds., 1998 ...

    A theoretical development that relates long-term averaged sediment delivery to the statistics of rainfall and catchment parameters is presented. The derived flood frequency approach was adapted to investigate the problem of regionalization of the sediment delivery ratio (SDR) across the Basin.Author: Hua Lu, Hua Lu, C.J. Moran, Ian P.
