Coconut Creek (Florida), ISSN 0749-0208. Breakwaters play an important role in coastal disaster prevention and mitigation. In this study, a numerical modelling of the wave run-up on dolosse breakwater is set up by integrating the CAD software SolidWorks and the CFD software FLOW-3D. The breakwater is built with the lower porous media and the upper armour blocks (dolosse), which is different from the current approach that treats the whole rubble mound breakwater as porous media. The numerical wave flume has been validated by analytic solutions of Stokes wave theory. The computational results are in good agreement with the empirical formulas under different wave conditions. The model...
