Current empirical methods often predict inadequately the overtopping discharges of waves on shallow sloping seawalls. As part of the DEFRA / EA funded research project FD2410, Coastal Flooding Hazard by Wave Overtopping, physical model studies have been undertaken for structure configurations of 1:2, 1:10 and 1:15. For 1:10 and 1:15 sloping structures, no data or method is currently available for predicting accurately the overtopping discharge. Although discharge quantities are widely used for analysing the hazard of overtopping, this may not be the best way of defining a violent overtopping event. Discharge velocities may also be of key importance and it is these velocities that are reviewed here for overtopping of waves on sloping structures. Two numerical non-linear shallow water models have also been used for comparison against the physical results to see whether they can be implemented as a valid prediction tool.
