SWASH (an acronym for Simulating WAves till SHore) is a non-hydrostatic wave-flow model and is intended to be used for predicting transformation of dispersive surface waves from offshore to the beach for studying the surf zone and swash zone dynamics, wave propagation and agitation in ports and harbours, rapidly varied shallow water flows typically found in coastal flooding resulting from e.g. dike breaks, tsunamis and flood waves, density driven flows in coastal waters, and large-scale ocean circulation, tides and storm surges.

The following benchmarks are currently available for SWASH:
