Abstract:
In this study, the beach profile evolution in front of a seawall was investigated through combining a large
scale physical model and a deterministic 2D-vertical cross-shore morphodynamic numerical model.
Experiments were conducted under erosive and accretive wave conditions, for two different water levels
at the toe of a seawall, affecting the wave-structure interaction and beach profile evolution. The results
show the importance of the wave-structure interaction determining the profile evolution. A better
agreement was observed between the numerical and physical results when that interaction is considered.
