| 摘 要： | 淮干中游分布着16个行洪区，堤内有堤。建立具有良好模拟精度和较高计算效率的洪水模拟模型是科学管理淮河流域洪水的难点和关键。基于MIKE11软件，以行洪时间和蓄洪量不变为原则，把行洪区概化为一维河道；提出了在缺少行洪区实测地形资料的情况下，利用行洪区水位-库容关系曲线概化行洪区河道断面的方法；针对行洪区各口门的不同控制方式，采用相应的概化方法并设置合理的控制参数，模拟洪水在主河道与多个行洪区之间的转换过程；采用2007年和2003年实测洪水资料，对模型进行率定和验证，结果表明该模型精度较高，能快速模拟行洪区进退洪过程及其调度规则。模型可服务于淮河中游洪水的科学安排与实时决策，其建模思路对闸坝众多的复杂河道洪水演进模拟具有一定借鉴意义。

| Abstract: | The middle reaches of the Huaihe River contain multiple flood detention areas and several dikes. It is difficult and yet imperative to develop a flood simulation model with high precision and calculation rate for the scientific flood management of the river basin. Using the MIKE11 software developed by the Danish Hydraulic Institute, the flood detention areas were simulated as one-dimensional rivers, according to the different control methods of each entrance of the flood detention area. This was done using different generalization methods and setting reasonable control parameters to realize the conversion process of the flood between the Huaihe River and the flood detention areas, with the principles of flood routing time and flood storage invariant. A method to generalize the channel profiles of the flood detention area was put forward, and we could use the reservoir water level-capacity curve when we lacked information about the terrain in the area. This model was calibrated and verified using the observed flood data of the years 2007 and 2003. The results show that the model has high precision and can quickly simulate the flood routing process and scheduling rules in this basin. The model can be useful for scientific management and real-time decision-making regarding floods in the middle reaches of the Huaihe River. The modeling process is of significance as a reference for developing flood routing models of rivers with numerous gates and dams. |
