Experimental and Numerical Simulations of Oblique Extreme Wave Conditions in Front of Breakwater’s Trunk

Abstract

Climate change studies already reported sea level rise as an accepted scenario, which induces changes in nearshore wave conditions. A large range of new experiences including water level, run-up, overtopping, hydrodynamic data for different wave steepness and direction was performed in the Leibniz Universität Hannover (LUH) wave basin for a rubble mound breakwater with a slope of 1(V):2(H). This work presents numerical simulations using OpenFOAM® of the hydrodynamics in that experiment focusing on oblique extreme wave boundary conditions and on their effects on the roundhead. We present a discussion of the wave generation boundary condition as well as comparisons of data from experimental measurements namely water level free-surface elevation and velocity data from ADV, as well as future guidelines to reach even better results.
