Liang, B.; Ma, S.; Pan, X., and Lee, D.Y., 2017. Numerical modelling of wave run-up with interaction between wave and dolosse breakwater. In: Lee, J.L.; Griffiths, T.; Lotan, A.; Suh, K.-S., and Lee, J. (eds.), The 2nd International Water Safety Symposium. Journal of Coastal Research, Special Issue No. 79, pp. 294-298. 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 was then used to calculate the wave run-up over movable dolosse breakwater, immovable dolosse breakwater and porous media breakwater under various wave conditions. The comparison results show that the porous media model can not sufficiently reflect the real world. And the displacements of the dolosse will affect the energy dissipation and lead to smaller wave run-up. It suggests that the interaction between waves and the dolosse breakwater is important for the safety of the breakwater. Therefore, the presented numerical study provides a more reliable approach for simulating wave run-up on dolosse breakwater that can provide support for the design stage of breakwater.
