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...

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.
