Breakwaters and Revetments
The individual wave overtopping, particularly the maximum individual volume, provides a better design of seawalls than the mean wave overtopping rate. This paper presents the influence of crown-walls on the probability distribution of individual wave overtopping and probability of wave overtopping Pow. It is revealed that the shape factor b increases exponentially with the increasing of the relative wall height, while Pow decreases exponentially as the wall height increases. Empirical formulae for the reductive effects of crown-walls on b and Pow have been derived, which provides a better design under the condition with crown-walls.
