摘要
基于环境水动力学数学模型对太平水道悬移质输运进行了计算 ,计算中用水平方向上的曲线正交坐标与垂直方向上的Sigma坐标相结合以及三维数学模型二维化的方法。并且在模型中嵌入悬移质输运模块 ,从而建立了一个针对太平水道的水流泥沙数学模型。计算结果与实测结果比较表明 :模型较好地重演太平水道潮流场以及悬移质输运过程 。
Based on the environmental fluid dynamics computer code, a mathematical model is developed to simulate the suspended sediment transport in Taiping Waterway. In developing the model, curvilinear orthogonal cordiuates in the horizotal, Sigma mapping coordinates in the vertical, and the treatment of two dimensions for the three_dimension problem are adopted. The application to Taiping waterway shows that the proposed model can reasonably simulate the tidal current and suspended sediment transport. It is suggested that the model could be applied to the similar tidal_infected waterways to calculate suspended sediment transport.
