Abstract

A storm passage results in acute beach erosion and loss of immense amounts of sand from the affected coastlines. Erosion may reach sand dunes which act as dynamic protective barriers, mitigating the impact of larger waves and storm surge. A dune starts being damaged by a storm when the wave runup is still confined in the swash zone; the region of beach foreshore which is intermittently influenced by the wave motion. Data acquisition in the highly dynamic zone is challenging during catastrophic weather conditions. Therefore, the fate of sand and the subsequent morphological change is difficult to predict. A near-prototype experiment was conducted to provide further insights in the physical mechanisms that result in dune erosion.
