Abstract:
Wave overtopping and breakwater steepness are believed to significantly influence
hydrodynamics and scouring mechanism in front of a breakwater. However, the
effects of these two factors have never been clearly described and completely
investigated in the existing studies. This problem creates a gap in the knowledge of
hydrodynamics and scouring mechanism in front of the breakwater. In the present
study, a two-dimensional numerical model based on the Reynolds Averaged Navier-
Stokes (RANS) equations and the Volume of Fluid (VOF) method is developed to
fill this gap of knowledge. The model is combined with a k-ε turbulence closure,
sediment transport, and morphological models with additional bottom shear stress
terms in the momentum equations.
