Abstract
    Over the last decades, numerical wave modelling is increasingly used as an additional tool that is complementary to physical modelling in the design and research of waves interacting with coastal structures. Accurate wave generation and thorough validation of these numerical wave models are crucial first steps in that process. Three prominent open source computational fluid dynamics (CFD) numerical models – OpenFOAM®, DualSPHysics and SWASH – are compared and successfully validated to large-scale physical model experiments in the Deltares Delta Flume (the WALOWA project) of waves interacting with a dike on a shallow foreshore (the typical geometry of e.g. the Belgian coastal defence system against flooding). In addition, a new wave generation method is implemented in SWASH to increase the accuracy of the generated wave field for practical applications beyond the state-of-the-art.
