Abstract

For the extension of the Rotterdam port in the Netherlands, a novel type of coastal defence structure has been built: a dynamic cobble revetment. During the recent years sand has washed-in between the cobbles altering its hydrodynamic performance. Currently no relations exist that can accurately predict this change in overtopping performance. As physical experiments on a scale large enough to prevent Reynolds (permeability) scale effects are both very costly and time consuming, numerical models are becoming a serious alternative. In this study the influence of a decrease in porosity and related cobble layer thickness on the overtopping performance is studied using a numerical model.
