| 摘 要： | 大沽河是胶州湾最大的入海河流,每年都会给胶州湾带来大量泥沙。本文利用三维的ECOMSED水动力-泥沙数值模型对洪水期的大沽河进行了数值模拟,得到了洪水存在期间以及洪水结束后胶州湾的余流分布、大沽河河道上中下游各层盐度、泥沙浓度随时间变化的趋势以及入海冲淡水和泥沙对胶州湾的影响。

| Abstract: | The Dagu River is the largest river flowing into Jiaozhou Bay;it brings large amounts sediment into the bay every year.In this paper,a 3-D hydrodynamic,sediment numerical model called ECOMSED is used to simulate the Dagu River during the flood season.The distribution of the residual current during and after flood,the change of salinity in each layer and sediment concentration for upstream,middle,and downstream of the Dagu River with time and the influence of fresh water discharge and of sediment on Jiaozhou Bay is obtained. |
