Abstract: In this study, the performance of vane attached to the bridge abutment and the influence of parameters such as height and angle of the vane installing in the reduction of local scour around bridge abutment were investigated. The results showed that the installing angle and height of vane had a significant impact on the reduction of abutment scour. So that the vane height increases, the performance of vane will be improve. Also the results showed that installing angle of 40 ° for vane is most appropriate angle. Following this research, three-dimensional components of velocity were determined with electromagnetic velocimeter around abutment with attached vane and used for drawing flow pattern. Investigation of flow pattern around bridge abutment in case of using submerged vane showed, this structure had the effective role on reduction of local scour by creating a low velocity zone around bridge abutment and control of primary vortexes.
