Abstract
Hydraulic model test has been carried out in order to study the characteristics of wave breaking, wave fission and wave regeneration on coral reefs which have steep slope in front. The two types of coral reef model, which have single and double step-like topography, are installed in wave flame. The wave transformation on coral reef is investigated in detail. The broken wave height and period on the coral reef are varied spatiotemporally due to wave breaking and wave fission.
In this study, we found that wave regeneration point can be estimated by ratio of distance from reef edge to wavelength of deepwater wave. The wave regenerated under the condition that the ratio was almost unity in these experiments.
