Abstract
The similarity law of the wind velocity in wave-overtopping experiments is not known. Then, in this study, the correspondence of the wind velocity in the wave-overtopping experiments to the one in the real coast was investigated experimentally based on the results of the field observation of wave-overtopping conducted by Fukuda, et al.(1974) in 1971-1972 at Niigata east port. Wave-overtopping rate, incident waves, wind direction and wind velocity, etc. were obtained in that observation. The experiments were conducted by using two-dimensional wave tank using the 1/45 reduced scale model. Generating the wave and the wind at the same time, wave-overtopping rates were measured. And the rates in the experiments were compared with the ones of the field observation. It was found that the wind velocity in the experiment becomes about 1/3 of the wind velocity of the real coast.
