Climate adaptation of coastal structures has become more important due to climate change. One of the climate adaptation measures is to reduce the wave loading before the waves reach the coastal structure. This can be achieved by constructing a low-crested structure in front of the coastal structure. To evaluate the performance of submerged low-crested structures Van Gent et al (2023) performed wave flume tests to examine wave transmission. For a submerged low-crested structure in front of a rubble mound breakwater the transmitted waves can be used as incident waves for estimates of wave overtopping, using wave overtopping expressions described in Van Gent et al (2022). However, to verify whether the system of expressions for wave transmission and wave overtopping can be applied for submerged low-crested structures in front of rubble mound breakwaters, new physical model tests have been performed.
