Model description
| Model type:
|
Modular model for the coastal domain.
|
| Description:
|
Xbeach is a two-dimensional model for wave propagation, long waves and mean flow, sediment transport and morphological changes of the nearshore area, beaches, dunes and backbarrier during storms. It is a public-domain model that has been developed with funding and support by the US Army Corps of Engineers, by a consortium of UNESCO-IHE, Delft Hydraulics, Delft University of Technology and the University of Miami.
