Abstract

Simple formulas are proposed to predict time-averaged reference concentration, diffusion coefficient and vertical distribution of suspended sediment concentration over ripple-covered bed, sheet flow layer and under agitation of breaking waves separately. Formulas of reference concentration and diffusion coefficient are in terms of wave, sediment and flow properties and reference concentrations are defined at levels where they can be measured without disturbance to the bed. Time-averaged concentration profiles are computed from steady diffusion equation. Published experimental data are better explained by the predictive models.
