摘要
通过建立大亚湾二维水质模型,以COD作为研究对象来模拟大亚湾海域COD浓度的变化情况及污染物的迁移扩散规律,并利用实测资料对模拟结果进行验证。研究结果表明,水动力模拟的结果能满足污染物扩散的水动力条件,水质和粒子追踪模型结果能真实反映大亚湾COD的浓度变化状况和输移趋势,受潮流影响,不同季节湾内COD浓度分布差别较大。
Based on the water quality model, this paper used COD as pollution index to simulate the changes of COD concentration and the law of pollutant transportation and diffusion in the Daya Bay. The simulation results would be verified by using the measured data. The results showed that the hydrodynamics simulation could satisfy the hydrodynamic condition of pollutant diffusion. The results of water quality and particle tracking model could reflect the changes of COD concentration in Daya Bay. Affected by the current, the COD concentration distribution in Daya Bay varied greatly in different seasons.
