In a situation where water overflow occurs on the seawalls due to a storm surge, generally it is high waves that cause wave overtopping. However, it is common that overflow and overtopping are modeled as separate phenomena, in a situation where both phenomena occur at the same time, the amount of water exceeding the seawalls may not be evaluated correctly. We improved the overtopping model based on Goda (2008) model and developed the model integrating wave overtopping and overflow. The high accuracy of the proposed model was confirmed by comparing with the wave overtopping diagram and CLASH datasets.
