# Engelund-Hansen (1967) Total Load Equation

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](https://cdn.document360.io/5074bc26-a9ef-4bf4-b1de-a5c6ce628aca/Images/Documentation/image018%281%29.gif) < 1.6 and for a mean diameter greater than 0.15 mm.
