Transformation of wave shape and spatial distribution of wave overtopping water over a coastal structure

Abstract

This work investigates the transformation of wave shapes and the landward spatial distribution of overtopping water over coastal structures by experimental data and a numerical model based on the Reynolds Averaged Navier-Stokes (RANS) equations and Volume of Fluid (VOF) surface capturing scheme (RANS-VOF). The aim of this study is to understand the transformation of wave shapes and the landward spatial distribution of overtopping water in the presence of coastal structures. This work provides new insights on the role of wave skewness and asymmetry on the breakwaters stability and sediment transport around the structure and on the beaches behind it. Also it helps to establish the extent of hazardous zones behind coastal structures when overtopping is anticipated.
