Abstarct: In recent decades, application of numerical models in simulation of local scouring around bridge piers taken into accounts by researchers. In this research using Flow 3D model local scouring around the rectangular bridge pier with round nose was simulated. Calibration results showed that RNG model with 780000 mesh and three mesh blocks, had good agreement with experimental results. Evaluation of numerical models in comparison with experimental results showed that Flow 3D is capable in simulation of local scouring. Investigation of numerical model approved that increase of the bridge pier angle increased scour depth and shear stress around the bridge, so that amount of shear stress for inline, 5 degrees and 10 degrees piers with flow direction was about 0.4, 0.42 and 0.55 N/m2. Also, increase of bridge pier angle caused more water surface fluctuations around the pier. As increase of height of vanes sediment controlling done better which decreased scour depth and shear stress around the pier. In this case for inline pier and height of vanes 0, 1.25 cm and 2.5cm in comparison with no support pier, shear stress decreased 99%, 98% and 97%, respectively. Performance of vanes in scour controlling had reverse relation with their angles. Investigation of results showed that vanes with 30 degrees angle and 2.5 cm height had best result. Increase of pier angle reduced the best model efficiency.
