Abstract

The propagation and evolution of solitary waves on a 3D submarine topography are investigated experimentally with wave gauge measurements, and acoustic Doppler velocimeter (ADV) velocity measurements. The contour map of the submarine 3D topography can be viewed as a slope composed of a series of circles studied by Whalin (1971). The arrival time of wave crest, the wave amplitude and deformation, and the velocity of water particles are analyzed. It turns out that the 3D topography has a significant effect on the wave amplitude and deformation of solitary waves but no obvious influence on the arrival time of wave crest. The distribution of velocity reveals the convergence of the flow and the generation of turbulence. The experimental results can be used as a benchmark for further validating 3D numerical models of breaking waves and provide more information in understanding the complex mechanism of transformation of a solitary wave propagating over the 3D submarine topography.
