Abstract

Various expressions have been developed for predicting the mean rate at which seawalls are overtopped by random waves. All of these expressions contain empirical coefficients derived from experimental data. The values of the coefficients are dependent on, amongst other parameters, the front slope of the structure. However, data are usually collected in physical model studies on seawalls with a limited range of front slopes (see, for example, Owen [1, 2]). Thus, it is generally necessary to interpolate the values of these coefficients for the purposes of design. The H&R overtopping model [3] is the latest proposal for predicting mean overtopping discharges. It is based more soundly than earlier models on a physical understanding of the processes involved. It has also been shown to provide the most promise for future development [4]. The pres
