胶州湾物质输运模型研究

为了更好地了解胶州湾的水动力特征，应用美国普林斯顿海洋模型研究了胶州湾的潮流特征。计算结果表明，胶州湾的潮流以往复流为特征，涨、落潮最大流均发生在胶州湾口，流速分别为73cm·s^-1和79cm·s^-1左右，潮波系统具有明显的驻波性质。在对胶州湾三维潮流模拟的基础上，建立了一个三维水质模型，并对环胶州湾主要河口陆源所输入的N、P污染物的浓度分布进行了模拟。通过与实测的调查结果进行对比，验证了模式计算的合理性。

Research on Numerical Model in Jiaozhou Bay

Princenton Ocean Model was applied to Jiaozhou Bay in order to provide the physical parameters for the study on the distributions of DIN and DIP and environmental effects. The model results show that the character of tidal current in Jiaozhou Bay is go - back flow and that Yellow Sea water enters Jiaozhou Bay from the northeast at maximal speed of about 0. 73 m . s^-1 at the channel and leaves Jiaozhou Bay from the northeast at about 0. 79 m.s^-1. The residual current of Jiaozhou Bay is controlled by four residual eddies. Based on the three dimensional simulation of tidal current, a three dimensional pollutant transportation and diffusion model was established and applied for simulating the distributions of DIN and DIP caused by the major rivers in Jiaozhou Bay. The simulated results agree well with the observed data in the field, implying that this water quality model is rea- sonable.
