胶州湾点源污染物扩散的二维模拟研究

Simulation Research of Point-sources Pollution Diffusion in the Jiaozhou Bay

建立动边界的平面二维水动力、污染物扩散数值模型,采用ADI法对胶州湾四方港区工程实施前后点源污染物的排放进行了模拟计算。研究表明,工程实施后,各类水质超标水域面积均略有增加,增加的面积主要分布在李村河口与海泊河口的河口混合区区段。

This paper presents a 2-D water dynamic and pollutant diffusion mathematic model with dynamic boundary and uses ADI method to conduct the simulation calculation of the discharge of point-sources pollutant before and after the construction of the Sifang Port Project in the Jiaozhou Bay. The research results showed that after the construction of the project, water area where various water quality indexes exceeding their standards is increasing to some extent, and mainly occurs in the intersection area between Licun and Haibo estuaries.
