Abstract

A procedure to estimate vertical diffusion coefficient and reference concentration of time averaged suspended sediment concentration caused by waves and current are discussed based on experimental results obtained in a laboratory. It is found that the non-dimensional diffusion coefficient normalized by the product of shear velocity u* and the equivalent roughness ks is more closely related to the Shields' number when the shear velocity is evaluated by using the equivalent roughness where the effect of ripple geometry is taken into account. The reference concentration is not a unique function of the sediment Shields' number. Incident wave period has also influence on the reference concentration.
