| 摘 要： | 在分洪区内存在河渠的情况下，根据水流在河渠外区域和河渠内运动特点的不同，对已有的分洪区二维水流数学模型进行拓展，建立了相应的数学模型。该模型计算时能考虑河渠两侧有、无堤防两种情况，通过对概化地形的计算，证明了模型的合理性。

| Abstract: | The former 2-D flow mathematic model for flood detention area constructed is improved and a new mathematic model is set up in the paper considering the difference between water flow movement peculiarities inside and outsider of river channel.The situation of with or without embankment on the both sides of drainage channel in flood detention areas is also considered in the model calculation.The new model is proved to be reliable through calculation of flood propagation in generalized topography. |
