| 摘 要： | 对珠江河口一维河网和三维河口湾斜压模型的水动力连接计算进行了研究。通过一维河网求解公式递推出口门连接处水位、流量关系式，然后依据三维模型计算得到口门连接处流量值，根据口门连接处的水位及流量连接条件计算出口门连接处的水位值，以此水位作为边界条件分别计算一维河网和三维河口湾斜压模型，实现了一维和三维斜压模型的水动力连接计算。对模型的连接计算进行验证对比，结果基本令人满意。

| Abstract: | A research on hydrodynamic connection calculation by a baroclinic model was carried out for one-dimensional river network and three-dimensional river estuary at Zhujiang River Estuary. Firstly the resolutions of water level and discharge at entrance connection were recurrenced by one-dimensional river network equation, then the amount of discharge at entrance connection was calculated based on a three-dimensional model as well as the water level according to the conditions of water level and discharge at the connection. Regarding this water level as a boundary condition, the calculation of hydrodynamic connection in onedimensional and three-dimensional baroclinic model for one-dimensional river network and three-dimensional river estuary was realized sucessfully. The result was validated and proved to be satisfing. |
