Numerical and Physical Modelling of Wave Overtopping on a Smooth Impermeable Dike with Promenade under Strong Incident Waves

This paper presents a study of run-up/overtopping over smooth impermeable dike with promenade using 2D and 3D mesh-based mesh-free numerical models results from physical modelling for strong energetic incident waves. These waves induce plunging wave breaking complex water/air mixture turbulent flow before overtopped the dike, challenging configuration models. The analysis is structured in two phases: (i) evaluates run-up overtopping; (ii) compares qualitatively overtopping between groins located front slope beach. indicate that main differences obtained are due to generation active absorption systems used by lead changes on height and, consequently, reflection, structure. For simulation, even if larger discrepancies were found along mean discharge water at crest groin head show similar order magnitude.
