The wave run-up is a key factor for determining the crest level of sloping dike and influences the engineering security and cost directly while a big deference existing between the calculating formulas in domestic and international codes and standards.With more and more Chinese enterprises participating in overseas projects,it is necessary for engineering designers to master different calculation methods of domestic and international design standards.This paper introduces the foreign commonly used standard American Coastal Engineering Manual(CEM),the European standard Wave Overtopping of Sea Defences Structures and Related Structures Assessment Manual(EurOtop) and domestic Code of Hydrology for Harbor and Waterway.By comparing the calculation methods of wave climbing and summarizing the differences among the calculation methods,the conclusion that the influence factors of wave climbing calculation taken into account by CEM and EurOtop are relatively comprehensive and practical is obtained.It provides some reference for the selection of wave climbing method in the design of slope seawall.
