    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 away through the detachment and transport of soil and rock by moving water, wind, and other geologic agents.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

    The Revised Universal Soil Loss Equation (RUSLE) and the Sediment Distributed Delivery (SEDD) prediction models were used to determine the quantity of eroded sediment and the sediment yield at the duck pond, respectively. These models require numerous computations, which were performed at the watershed scale with the aid of ArcGIS software.

    The annual sediment load (sheet and rill erosion only) is calculated based on the Universal Soil Loss Equation (USLE) and the sediment delivery ratio. The sediment and pollutant load reductions that result from the implementation of BMPs are computed using the known BMP efficiencies.

    Estimating Sediment Discharge John R. Gray and Francisco J. M. Simões D.1 INTRODUCTION Sediment-discharge measurements usually are available on a discrete or periodic basis. However, estimates of sedi-ment transport often are needed for unmeasured periods, such as when daily or annual sediment-discharge values are

    Dec 31, 2007 · The Universal Soil Loss Equation (USLE) or the revised USLE (RUSLE) are often used together with sediment delivery ratios in order to predict sediment delivery from hillslopes. In using sediment delivery ratios for this purpose, it is assumed that the sediment delivery ratio for a given hillslope does not vary with the amount of erosion ...Author: P. I. A. Kinnell
