EFDC模型在港湾水环境中的应用及进展

The Application and Advance of Environmental Fluid Dynamics Code(EFDC) in Harbor and Bay Water Environment

加强港湾水域的环境控制是海洋管理的重要方面,而水环境系统的模拟是进行环境控制的前提条件。EFDC(Environmental Fluid Dynamics Code)由美国威廉玛丽大学维吉尼亚海洋科学研究所开发的综合水质模型,使用范围广泛,能够模拟河流、湖泊、河口、水库、湿地,以及近海区域等多种水体的水动力、水质状况、沉积物迁移等。介绍EFDC的基本原理、方程及综述了其在港湾水环境模拟方面的应用和发展。

Water environment simulation is the prerequisite of the environmental control,which is important for marine management.EFDC( Environmental Fluid Dynamics Code) is developed according to multiple mathematical models by Virginia Institution of Marine Science.It has a wide application in water systems including: rivers,lakes,estuaries,reservoirs,wetlands,and near-shore to coastal regions which can simulate the flow,transport,and biogeochemical process happened in them.In this paper,based on lots of reference literatures,the principle,primary equations and application process were introduced respectfully.Then its application and advance in harbor and bay water environment simulation were also summarized and analyzed.
