Abstract

A dynamic revetment is a gravel ridge constructed around the wave runup limit to mimic composite beaches which consist of a lower foreshore of sand and a backshore ridge constructed of gravel or cobbles which stabilises the upper beach and provides overtopping protection to the hinterland. These structures contrast with static coastal defence structures as they are “dynamic†and are expected to reshape under wave attack. The performance and resilience of a dynamic revetment under sea level rise (SLR) for a range of wave conditions was studied in a large scale laboratory flume. This work provided new information about the application of such structures for coastal protection in the face of a rising sea level.
