Abstract

Beach profile change due to overwash has a major impact on both developed and undeveloped coasts following storms. The ability to predict such profile change has been further developed within a numerical beach profile change model, taking into account lateral spreading and infiltration on the back slope of the beach, and overwash where the beach crest becomes inundated. These new capabilities were tested for overwash of a low flat barrier and where dunes are present, reproducing well both the volume and shape of the overwash deposits.
