【摘要】 运用一个含动边界的二维河口海岸动力模型模拟了福清湾潮汐潮流的基本特征,模拟结果与实测数据吻合较好.在此基础上估算了福清湾涨落潮流历时,分别为6 h 19 min 2 s和6 h 3 min 48 s;大小潮周期的纳潮量,分别为10.94×107和4.47×107m3;福清湾的半交换和80%的交换周期分别为3和6 d.最后,以COD为例,给出了在排放稳定后保守污染物的分布特征.更多还原

【Abstract】 A modified 2-D estuarine coastal ocean model(ECOM) with moving boundaries is used to reproduce the tidal regime in the Fuqing Bay.Simulations agree with observations reasonably.By means of estimation,it is found that the current duration of flooding and ebbing are 6 h 19 min 2 s and 6 h 3 min 48 s,respectively.The tidal prism during the spring and neap are 10.94×107 and 4.47×107 m3,respectively.Additionally,the conservative COD is added to the model.Based on the transport character of conservative tracers,the half and 80% of water exchange period are 3 and 6 days,respectively.更多还原
