Characteristics of interactions among a row of submerged vanes in various shapes

The technique for simulating bed profile induced by submerged vanes so far has been limited to flat plates in the shape of a rectangle. In this study, we advanced the simulation technique to vanes with any shape. An innovative approach to take into account the boundary effects of channel banks, water surface, and channel bed was also proposed. A numerical model was developed to explore the influence of vane shapes on the induced transverse bed profiles. The extent of vane shapes on the interaction effect in a system of vanes was also investigated. Certain characteristics about submerged vanes in different shapes were observed and discussed, which might be of help for vane system design at preliminary stage.
