   Sammanfattning : Sediment transport in the cross-shore (CS) and associated changes in the beach profile, especially during storms, have been topics of widespread concern. Since storms are often accompanied by high water levels and large waves, large quantities of sand from the beach and the dune are typically transported offshore, leading to severe beach and dune erosion, which threatens the integrity of buildings and infrastructure near the coast.

   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; overwash; washover; hurricane impacts; dune erosion; barrier islands;

   Sammanfattning : Overwash is the flow of water and sediment over the crest of a beach system when the runup level of waves or the water level, often enhanced by storm surge, exceeds the local beach or dune crest height. The impacts of overwash on coastal barriers or low lying mainland coasts are striking. LÄS MER
