Structure and Sediment Interactions
The performance and resilience of a dynamic revetment under sea level rise (SLR) was studied in the GWK Large Wave Flume, Germany. As the water level rises, the cobble berm starts rolling over, with cobbles being transported onto and over the crest during large runup events. This process causes the revetment to move landward and gain in elevation with SLR, while the crest thickens. The front slope of the revetment steepens significantly but the entire structure shows a resilient stability. The revetment stabilises the sand underneath and limit its erosion as well as slowing down the shoreline retreat.
