Setting tolerable wave overtopping criteria based on the revetment function is one orientation in wave overtopping study. It makes sense to study the calculation of individual overtopping wave volumes,since it will facilitate the drainage design behind the revetment. We summarize the popular used tolerable wave overtopping criteria and calculation formulas,and discuss the impacts of the berm and the correlation of parameters in the calculation formulas based on the south revetment of the Ras Al Khair Port expansion project. The results show that the tolerable wave overtopping criteria listed in European standards and the United States standards are stricter than in Chinese standards and Japanese standards. Setting a reasonable berm and considering the correlation of wave height and water level can decrease the value of the calculated overtopping volume. The calculated overtopping volume is highly sensitive to wave height and water level,the tolerable overtopping volume can be classified in reasonable magnitudes. Considering the impact of the berm and the correlation of parameters in wave overtopping calculation can benefit the contractor,especially in projects that require extremely low overtopping discharge.
