基于FVCOM 的辽东湾水动力特性数值模拟

辽东湾属于半封闭性海湾， 水动力过程具有一定的代表性。本文基于无结构化三角形网格的有限体积海岸海洋模型FVCOM（Finite-Volume Coastal Ocean Model）， 构建了辽东湾及其邻近海域的三维水动力数值模型， 并利用实测数据对6 个潮位验潮站、4 个潮流验潮站的大小潮时刻的潮位、流速、流向进行了对比验证， 该模型能够准确地模拟辽东湾的潮汐、潮流等水动力场情况， 可进一步为研究辽东湾温盐、泥沙、水质、污染物扩散等提供研究基础。

Numerical Simulation of Hydrodynamic Characteristics of Liaodong Bay Based on FVCOM

As a semi-closed bay, Liaodong Bay has certain representative hydrodynamic characteristics. A three-dimensional hydrodynamic numerical model of Liaodong Bay and its adjacent sea areas was constructed based on the FVCOM. The tidal level, flow velocity and flow direction at the time of big and small tides were compared and verified at six tidal level tide stations and four tidal tide stations. The model could accurately simulate the tidal, tidal current and other hydrodynamic fields of Liaodong Bay. It could further provide a research basis for the study of temperature and salinity, sediment, water quality, and pollutant diffusion of Liaodong Bay.
