  According to the conditions of any river, different methods are used to protect of erodible rivers bank. One ofthese methods is the use of banks protection structures such as submerged vanes. The main problem of thesestructures is to local scour of around the nose structure. One of the effective methods of flow patternimprovement around the structures is creating slot in structure. In this study, has been created rectangular slot(with fixed dimensions) in three different positions in bank attached triangular vane, this means that the slot isparallel to the chord in first vane, parallel to the base in second vane and parallel to the vertical side of triangularvane in third vane. The research aim is to determine the slot optimal location, with defined dimensions.Experiments were conducted in the single-vane posture and under different hydraulic conditions (clear watercondition). Results showed that the first vane (slot is parallel to the chord) had the best performance to reductionof volume, Length and width of scouring. Also, the maximum scour depth in this vane was 35% and 13% lessthan two other vanes that slot is parallel to the base and parallel to the vertical side, respectively. Manuscript profile

  Bridges are among the most important and most prolific river structures ever used. The three commonly used methods to deal with the scouring phenomenon around the bridges are to place the piers in a lower level than the depth of the erosive pit, to reduce the power of the vortex produced around the base, to use the shrub protection cover, or to use a collar, gaps, or submerged plates around the base bridges. Submerged plates are structures that are installed at the bottom of the river with an angle to the main stream and to prevent river erosion, rivets and base structures of the water and waterway reformation and morphology of the bed, which produces a secondary vortex and Changing the flow pattern in the river bed and, consequently, changing sediment transport and erosion. In this research, the effect of square cross-sectional diameter and the effect of submerged panels on scouring are investigated using SSIIM software. Manuscript profile
