On quay walls where multiple reflections of waves prevail, and continuous seawalls where wave shielding effects affect incident waves on adjacent seawalls, model experiments and numerical calculations, which are conducted by virtually removing target facilities to obtain incident waves, are unable. Therefore, we conducted a hydraulic model experiment using an experimental flume and a reproduction calculation using the Boussinesq model including a wave overtopping model and a wave pressure calculation formula. By applying Takayama’s approximation formula for the design diagrams of wave overtopping rate of vertical seawalls and Goda formula of wave pressure in reverse, the equivalent deepwater wave height, which is the input value of these, was determined by convergence calculation and compared with the known incident wave (equivalent deepwater wave height) at the target facility. As a result, we confirmed that incident waves with different wave heights or periods (equivalent deepwater wave height) can be estimated correctly from wave overtopping discharge and wave force, although these estimates from wave force are slightly underestimated.
