摘　　要：基于无结构三角形网格FVCOM模式,建立长江口高分辨率三维水动力数值模型,采用大量水文观测资料进行验证,使之能合理反映长江口,特别是横沙浅滩区域的水动力结构及其变化,为横沙浅滩挖入式港池方案的影响分析提供合理可靠的数值工具.Based on an unstructured-grid FVCOM model, a high-resolution hydrodynamic model of the Changjiang Estuary has been established. Through the extensive validation against the va- rious observation data, including the current and salinity, this model could correctly reveal the hydrodynamic structures and their variations. It has provided a basic tool for assessing the im- pacts of the proposed excavated-in harbor of the Hengsha Shoal on the current field on local and adjacent regions.
