In order to reduce the impact of bridge pier groups on the water flow at the intersection of the main rivers of Hangzhou Zhijiang New City, three shoreline optimization schemes were studied to improve the flow pattern based on a two-dimensional mathematical model. The optimal remediation plan was recommended based on multiple objectives such as water resistance ratio, land area, water area, bridge pier safety, and so on. The results show that the widening one side of the river channel to prevent bridge piers from being located in the main channel or changing the route to avoid bridge piers can effectively reduce the impact of bridge piers on the water level. The three optimization schemes have the same improvement effect on the backwater of the bridge piers. Scheme 2 and scheme 3 will affect the safety of bridge piers, with relatively small water area and large land acquisition area. Scheme 1 has little impact on the safety of bridge piers and is relatively easy to implement. Scheme 1 has high comprehensive advantages, and is recommended as the optimal option.
