Numerical investigation of wave hydrodynamics and scour due to overtopping and steepness of breakwater

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.
