| Abstract | Wave overtopping of rubblemound breakwaters is a complex physical process which influences the functional efficiency and structural stability of the structure. The mean overtopping discharge resulting from design wave and water level conditions is often an important consideration affecting the selection of breakwater profile and crest height. The volume of water which passes over the crest of a breakwater depends on the structure geometry and composition, the nearshore bathymetry, the water level, and the seastate conditions. Physical modelling at large scale has traditionally provided a robust and reliable means to support the design of rubblemound breakwaters. Recent advancements in computational fluid dynamics and computing power have led to increasing efforts to use numerical modelling as a complementary tool to physical modelling for breakwater design applications. This paper compares measurements from a physical model study of rubblemound breakwaters conducted by the National Research Council of Canada (NRC) with numerical simulations produced by the numerical model IH2VOF. The skill of the IH2VOF model in predicting free-surface elevations and mean wave overtopping discharges is assessed. The comparisons are conducted for a range of seastate conditions, water levels, and breakwater geometries. The findings demonstrate that IH2VOF offers a viable tool to complement physical model testing for rubblemound breakwater design applications. |
