Abstract: Clarifying the effects of wave-dissipating block shape on the flow around the block is one of the effective ways to consider the shape characteristics of block in the performance-based design. In this study, hydraulic model experiments of flow around a block with three different shapes, installed in an open channel, was conducted for examining the shape effects of the block such as round, angular and dimple shape, by measuring surrounding flow characteristics by the particle image velocimetry (PIV).
