| Research Abstract |
Surfer's maximum velocity (kinetic energy) obtained from wave motion is formulated as a function of surf similarity parameter (Combination parameter of surfing reef's front slope, wave length and water depth). The optimal shape of surfing reef is determined using this formula. Hydraulic experiment shows that the wave energy is dissipated after the wave breaking on the surfing reef. On the ebb tide, the wave height reduces to 30% due to wave breaking. On the other hand, large wave dissipation is not expected. Rip current at the lee side of surfing reef becomes larger and sometimes causes erosion. Surfing science and technology symposium was held 3 times. At the symposium, the benefit from surfing reef, the Tsunami control by reefs and etc were discussed.
