Series of laboratory experiments have been carried out to investigate on splash height and overtopping rate of block mound seawall. The splash height and overtopping rate are formulated as a function of the relative crown height and deepwater wave steepness. Probability distribution of a splash height is calculated by using the joint probability density function of significant wave height and period proposed by Mathisen and Bitner-Gregersen. Representative heights of a splash over a seawall are evaluated with the probability distribution function. The present method is applied to estimate the expected heights of wave spray during the occurrence of storm waves on the Oyashirazu Coast in Niigata Prefecture.
