Effectiveness Of Stilling Wave Basins In Reducing Wave Overtopping On Dikes And Rubble Mound Breakwaters

Abstract

Motivated by the impacts of Climate Change (CC), such as rising sea levels and the increased intensity and frequency of storms, the importance of adapting our coastal defense structures has never been more important (Toimil, 2020). With CC causing coastal structures to be exposed to more extreme hydraulic conditions than originally designed for, there is an increased risk of these structures failing in terms of stability and hydraulic performance, such as wave overtopping. To reduce wave overtopping, structural modifications of existing coastal structures are often adopted and in this work the analysis of wave overtopping discharge at slope structures equipped with Stilling Wave Basins (SWB) at their crest (Figure 1) is investigated.
