| 摘 要： | 应用ADI法首次对整个珠江口河口海区的潮汐和潮流进行了数值模拟。与实测值相比,潮位、潮流场、佘流场和八大河口门潮量等的模拟计算结果令人满意;还计算了拉格朗日余流场和拉格朗日标识质点运动轨迹,并对此进行了探讨。

| Abstract: | The tides and tidal currents in the Zhujiang Estuary are simulated by employing finite difference methods. The computed areas include the whole Zhujiang Estuary where the tides and tidal currents are influenced by the eight mouths of the Zhujiang The computed tidal levels and tidal currents are in good agreement with field measurements, and the comparison between the caculated tidal influxes and the field observations exhibits excellent agreement. According to the computed tidal current, the fist author also computes Lagrangian residual currents and discusses the exchange extent of the water bodies. In addition, the Euler-Lagrangian method is used to track the trajectory of pollutant water mass from the possible outlets in the estuary. |
