Description :
Based on experiments in 2 flumes with fixed and mobile plane beds and previously published data, an equation is developed that may be used to predict bedload transport resistance for both capacity and non-capacity flows. The variables in this equation are identified by dimensional analysis and the coefficients are determined by non-linear regression. This equation applies to rough turbulent open-channel flows, where the relative submergence is between 1 and 20 and the entire sediment load moves by saltation.
