Abstract: The scour phenomena one of most important can be happened to bridge when construction in the stream which can cause the collapse of the bridge. Euphrates River is one of the most important rivers on which many of the bridges are set up. The bridge of Imam Ali, this bridge is situated in Najaf government. In present study, a modeling of the Imam Ali Bridge by using the (HEC-RAS) program was prepared for discharges of 40-1400 m3/sec. Two types of scouring appeared these are a pier scour and a contraction scour. The first increased with increase discharge while the second decreased with increase discharge. The results give a good indication that the Imam Ali Bridge is safe against the scouring.
