Overtopping of seawalls

A project was carried out to collate all relevant information on the overtopping of seawalls through a review of all available existing research the reanalysis of some data and additional experiments.

The research has concentrated on providing techniques for predicting the mean overtopping discharge, and hence consequent flood volumes and drainage requirements for a range of commonly occurring seawall types. Little, or no attention, has been paid to either the peak individual (wave-by-wave) overtopping discharge or to the numberof waves likely to overtop a particular defence, despite the importance of these two parameters in determining the overall standard of performance of a sea defence.
