| 摘 要： | 根据平原感潮河网的水力特性，研究复杂河网非恒定流计算问题，利用圣维南方程组、节点连续方程及边界条件建立了水动力数学混合模型。将模型应用于宁波市鄞东南水系的河网计算，并利用2005年“麦莎”台风实测水文资料对模型做了检验。验证结果表明，建立的水动力数学模型是可行的，可以用于平原感潮河网地区的水力计算。

| Abstract: | According to the hydraulic characteristics of tidal river network in plain,the hydrodynamic mathematical model is set up for the research on unsteady flow computation in complicated river network by using Saint-Venant equations,nodal continuity equations and boundary conditions.The hydrodynamic mathematical model has been used for the river network computation in Ningbo river system and checked by using the hydrological data measured in the period of"Maisha"typhoon in 2005.The result proves that the hydrodynamic mathematical model is feasible and it can be used for the hydraulic computation in tidal river network area in plain. |
