Abstract: The stability and transport of beach material in front of coastal structures depends to a very large extent on the near-bed hydrodynamic regime generated by the interaction of incident and reflected waves. The interaction can lead to serious beach level reduction and scour at the structure toe. In an effort to understand and to be able to predict the near-bed velocity field, experiments have been carried out in which velocities have been measured in front of vertical and sloping sea walls subject to attack from normally-incident random waves. Comparison of measured and predicted velocities suggest that a relatively simple prediction method could be used to determine the velocity field to be used as input for beach stability calculations.
