XBeach is an open-source numerical model which is originally developed to simulate hydrodynamic and morphodynamic processes and impacts on sandy coasts with a domain size of kilometers and on the time scale of storms. Since then, the model has been applied to other types of coasts and purposes.
The model includes the hydrodynamic processes of short wave transformation (refraction, shoaling and breaking), long wave (infragravity wave) transformation (generation, propagation and dissipation), wave-induced setup and unsteady currents, as well as overwash and inundation. The morphodynamic processes include bed load and suspended sediment transport, dune face avalanching, bed update and breaching. Effects of vegetation and of hard structures have been included. The model has been validated with a series of analytical, laboratory and field test cases using a standard set of parameter settings.
The XBeach community website can be found at http://xbeach.org, which hosts a user forum, daily builds and test reports.
The XBeach source code is hosted in the Deltares Open-source Software (OSS) Subversion repository at https://svn.oss.deltares.nl/repos/xbeach/trunk. This Github repository is a mirror of the Subversion repository as a convenience for automated services like Read the Docs, CircleCI or DockerHub.
The Github repository is synchronsized with the Subversion repository at midnight, but not the other way around. The Github repository should therefore not be altered directly. In the near future XBeach will be migrated to its own Github organization.
