Abstract: With two dimensional mathematic models, the navigation flow condition before and after the bridge construction is analyzed. The water surface profile and flow field is calculated and analyzed, which indicates that the construction of Zhouhe Bridge has small impact on the change of the water level, the discharge area and the width of the river and little impact on the main fiver flow field. The feasibility of the construction of bridge is proved.
