Abstract
Recently, wave overtopping due to heavy storms increase in ice-infested sea area in winter. However, sufficient examination has not been carried out on the wave runup characteristics in ice-covered area. In this study, hydraulic model experiments and simulation by the coupling of the two model(SWAN - CADMAS SURF) is carried out to investigate wave runup characteristics. The proposed simulation method gives a good agreement with the observed wave data and experimental results. Furthermore, the results of the experiments show that reduction in wave runup heights due to block mound breakwater.
