The vortex shedding process induced by a solitary wave propagating over a symmetric cavity was studied experimentally, using the particle image velocimetry (PIV) technique and flow visualization technique. The wave height of the solitary wave is 1.4 cm, and the wave height (H) to water depth (h) of the experiment is 0.2. The ratio of the length to the depth of the cavity, A r, was defined as aspect ratio. The vortex shedding processes were investigated particularly for Ar = 0.5 using the flow visualization technique and PIV. The quantitative characteristics of shedding primary vortex in the cavity, such as the trajectories of the vortex core and jet like flow, vorticity of the primary vortex core, and the circulation of the primary vortex, were studied in detail. Finally, it is found that all the characteristics change obviously while Ar is less than 1.0.
