Piles are commonly used in river and ocean engineering to support structures on top of the water surface. The examples of pile structures including bridge piers, legs of offshore platforms, foundation of wind farms. When a vertical circular pile is placed on an erodible bed, the amplification of the water flow velocity leads to local scour of the sediment around the structure. Local scour has attracted much attention because it is one of the main reasons that may cause structural failure in both bridge engineering and offshore engineering. By using this device properly, local scour around submarine foundation can be reduce up to 50%.Fig. 1 2
