The purpose of this contribution is the analysis of the characteristics of the flow (velocities and layer thicknesses) on the dike crest. This analysis is carried out on a numerical database derived by running the Rans-Vof code (IH-2VOF) developed by the University of Cantabria in presence of submerged impermeable structures characterized by different slopes. For zero freeboard structures, numerical flow depths and velocities over the dike crest are represented quite well by the theoretical existing models. In case of over-washed structures, the numerical discharges can be accurately reproduced by the sum of the overtopping and storm surge components.

Abstract

The purpose of this contribution is the analysis of the characteristics of the flow (velocities and layer thicknesses) on the dike crest. This analysis is carried out on a numerical database derived by running the Rans-Vof code (IH-2VOF) developed by the University of Cantabria in presence of submerged impermeable structures characterized by different slopes. For zero freeboard structures, numerical flow depths and velocities over the dike crest are represented quite well by the theoretical existing models. In case of over-washed structures, the numerical discharges can be accurately reproduced by the sum of the overtopping and storm surge components.
