It occurs mainlyduring flood events. To find the most effective countermeasure to protect water structures againstscouring phenomena, extensive investigations have been performed. One of such methods is to usesubmerged series of vanes which is not fully investigated yet. In this study, two series of submergedvanes were used either separately or attached to the upstream face of bridge pier and arrangedsymmetrically on different positions and angles of attack to control scour at cylindrical pier underclear water condition. The results showed that the highest reduction in scour depth occurs as the vanesseries stands closer to the pier. Under the best condition, scour depth was reduced by 80.9 percent.
