Increase of bottom shearstress of a current due to wave motion

Due to the increased velocity vector in the case of current combined with waves the bottom shear stress in the direction of the current will increase. This increase has been derived and the derivation has been checked by measurements

Littoral drift computations on mutual wave and current influence

11th Conference on Coastal Engineering in London 1968, the author presented a method for computing the littoral drift starting from the longshore current velocity as this is generated by the waves and with the assumption that the material is stirred up by the waves. In this paper measurements in a model basin are described by which the procedure is further tested. A comparison with littoral drift rates computed by this procedure and derived from accretion and erosion rates along the coast of Queensland (Australia) are presented. For a hypothetical coast the littoral transports with varying bed roughness are computed. The influence of this roughness on the assumptions forming the basis of the computation procedure is discussed.Hydraulic EngineeringCivil Engineering and Geoscience

Some considerations about scales for coastal models with movable bed

Starting from the increase of the bed shear of a uniform flow due to wave motion~ a transport formula for waves and current has been derived. With this transport formula scale relationships have been derived for models in which material transport, under the combined influence of waves and current has to be reproduced.Civil Engineering and Geoscience
