Abstract

The height of seawall is determined based on allowable wave overtopping rate or wave runup height for the design of surge and wave prevention facilities. Although a design method based on wave overtopping rate takes into account of wave randomness, a design method based on wave runup height does not consider the wave randomness but uses equations and figures obtained from regular waves. Therefore, a unified prediction formula for random wave overtopping and runup is required for establishing the design scheme of seawalls. This study proposes prediction formula for random wave overtopping discharge including wave runup for seawalls with composite cross section installed near shoreline.
