河道与蓄滞洪区联合防洪数值模拟研究进展

基于目前河道与蓄滞洪区联合防洪过程中存在的问题,本文通过对河道与蓄滞洪区联合防洪过程中洪水演进数值模拟的一维模型、耦合模型、全二维模型的优缺点和适用性进行系统化的分析,揭示了未来防洪数值模拟的发展方向。研究结果可为洪水风险图绘制、洪水预警预报提供重要依据,对防洪减灾决策具有重要指导意义。

Research progress on numerical simulation of joint flood control in river and flood detention area

Based on the existing problems in the process of flood control in the river and flood detention areas, this paper conducts a systematic analysis of the advantages, disadvantages and applicability of the one-dimensional model, the coupling model and the two-dimensional model of the numerical simulation of the flood control in the flood control process, and reveals the future development of numerical simulation of flood control. The results can provide important basis for flood risk mapping and flood warning and forecasting, which is of great significance to the decision of flood control and disaster reduction.
