Abstract: This study uses a combination of a RANS-VOF wave model and measured bed profiles to study the impact of toe scour on wave overtopping over a vertical wall. Model data analysis has been carried out to exam ine mean wave overtopping discharges, and ultimately identify the physical processes behind wave overtopping in the presence of toe scour. Results show that the toe scour reduces the wave overtopping through enhancing wave breaking over the considerable deposition associated with toe scour. However, with a scenario of negligible deposition and large toe scour, it increases the wave overtopping by enabling more giant waves to reach the wall.
