【 摘 要 】

The vast majority of overtopping data applied in EurOtop (2018) has been made from small-scale measurements with impermeable foreshore slopes. This article describes a comprehensive two-dimensional experimental study conducted in a small-scale 1:50 wave flume. Results are presented for the overtopping performance at a 1 to 2 sloping wall, undertaken on both impermeable and permeable foreshore slopes. Within experimental limitations, the results demonstrated that the mean overtopping rate is reduced by up-to a factor of 4, when compared to the predictions reported for the impermeable slope. However, when comparing maximum individual wave-by-wave overtopping volumes, no significant differences were observed. These results are intended for practitioners and researchers predicting wave overtopping characteristics at sloping structures with permeable gravel foreshores.
