Some calculation methods of wave run-up stipulated in Chinese codes have some defects,especially under the long wave condition.The formulas of relatively limited applicability even do not take long wave into account.So there is a huge deviation between the calculated value and the actual result,which may cause some potential danger.This paper mainly studies the influences of different types of protective facings of sloping breakwater on the irregular wave run-up through a series of sectional physical model tests and proposes the correlation coefficient and empirical formula to provide theory reference for the design of protective facing on the river side slope which is on open water areas.
