Abstract
In a wave basin, a multi-directional wave is generated in nearly deep water by a serpent-type wave maker. Its transformations in shallow water are reproduced on a bathymetry model installed in physical, however, its range is restricted with both an area of the wave basin and an applicable model scale considering the scale effect. Therefore, it may be much effective for expanding the wave test area in virtual to generate the transformed multi-directional waves in shallow water. In this study, the serpent-type wave maker is improved to install such a function with a energy balance equation model, and a model experiment of multi-directional wave overtopping on revetments on sloping bathymetry is conducted to show both an effect and a problem of generating the transformed multi-directional waves in shallow water.
