Wave?Current Interaction and Sediment Transport

by Jan van de Graaff, Delft Univ of Technology, Netherlands,



Document Type: Proceeding Paper

Part of: Sediment Transport Modeling

Abstract:

The paper reports on a study into whether a close relationship between the mixing (diffusion) coefficient for the sediment, ?_s, and the mixing (diffusion) coefficient for the fluid, ?_f, does exist under the combination of waves and currents and whether ?_s distributions derived from sediment concentration measurements can be used to predict the shape of the current velocity distribution plotted as a function of the vertical orbinate measured from the bottom. Some results of tests carried out in the Fluid Mechanics Laboratory of the Delft University of Technology are discussed.
