Abstract: The technique of submerged vanes is a new and efficient sediment management method in rivers. This method has positive environmental effects. The performance and efficiency of a submerged vane is related to its shape. In the present study, physical hydraulic model testing is performed to investigate four shapes of vanes: a simple rectangular vane and three vanes that are beveled at leading edge in 30, 45 and 60 degrees with respect to the base, respectively. The experiments show that cutting the leading edge of the vanes reduces the local scour around the vanes. Maximum scour depth reduction occurred due to the maximum chamfer at leading edge of the vanes. Based on the results, cutting the leading edge of the vanes is a performance improving and also cost saving modification, too.
