NUMERICAL SIMULATION OF THE DEBRIS BEHAVIOR AFFECTED BY WAVE BREAKING

In the design and risk assessment of coastal structures against collision of tsunami debris, it is necessary to analyze the collision probability and set the appropriate collision speed of the debris. Given the pronounced influence of flow fields and structures on the collision probability and collision speed, it is desirable that the motion of debris moving with the tsunami be taken into account in these analyses and settings. If a tsunami causes wave breaking, implementing the setting of the collision probability based on a consideration of the effect of wave breaking on debris motion is necessary.
