A wave flume is commonly used in solitary wave boundary layer research. However, it is hard to reproduce near-bed hydrodynamic and sediment transport phenomena at a realistic scale. Latterly, an oscillating water tunnel has been utilized to examine turbulent solitary wave boundary layer (Sumer et al. 2010). Both of experimental facilities actually have main difficulty to achieve reliable ensemble average. In this study, a new generation system for solitary wave boundary layer which enables to do measurement under single and periodical motion is proposed. As a result, single and periodical measurements confirm a good agreement. It is concluded that the new generation system is able to investigate solitary wave boundary layer and applicable for sediment transport experiment by facilitating ensemble averaging.
