    Engelund-Hansen (1967) Total Load Equation


    Article summary

    The Engelund-Hansen equation was developed by equating the work done by the drag forces of the flow to the potential energy gained by particles as they move up the face of a dune. The form of the equation used is:

    Where

    G = volumetric sediment transport rate

    K = calibration coefficient (=1 for standard equation)

    W = width of flow

    V = water velocity

    h = flow depth

    S = water surface slope

    s = specific gravity of sediment

    D = sediment diameter

    g = acceleration due to gravity

    The factor 0.05 in the equation was set using empirical data.

    The suggested applicability of the Engelund-Hansen equation is for image018(1).gif < 1.6 and for a mean diameter greater than 0.15 mm.
