| 摘 要： | 运用可计算河口流场的全三维数值模型研究Gironde河口的河口环流与盐水入侵问题。本模型应用有限差分法求解浅水方程,同时采用模态分裂技术获取关于水位的泊松方程。而湍流计算则采用二阶K-L模型求解。模型采用Gironde河口两次不同实测数据进行率定参数与验证。通过对潮汐与径流作用的详细分析以研究该河口动力结构及影响河口环流盐水入侵的主要影响因素。

| Abstract: | A full 3-D numerical model for calculating estuarine flows is used for studying the estuarine circulation and the saline intrusion in the Gironde estuary.The model is based on resolving the shallow-water equations by a finite differences method using the splitting-up tech- nique to get a Poisson equation for the water surface level.The turbulence is taken into account by the two-equation model K-L.The model was calibrated and verified using the data measured during two field surveys in the Gironde estuary.A study on the influence of tides and river discharges was realised to understand the hydrodynamic structure and the main factors that can be responsible of changes of estuarine circulation and saline intrusion. |
