摘要
为阐明樟里河河滩湿地对河道洪水的影响,指导工程施工,在率定好一维数学模型的基础上,建立了平面二维数学模型,定量计算有无湿地、湿地有无过水涵洞工况下对水位、流场形态的影响。结果表明,湿地的防洪减洪、削峰缓流作用明显,涵洞的存在减少环流,有效降低水位差、流速差。研究结果可为河道治理与防洪安全提供参考。
In order to assess the impact of wetland on flooding in Zhangli River and offer guidance for project construction,a two-dimensional mathematical model is established to calculate the flow procession of wetlands combined with culverts after reasonable calibration by one-dimensional mathematical model.The results show that the wetland has an obvious effect on flooding control,and the culverts in wetland can obviously reduce circulation,which can reduce water level and flow velocity effectively.The research findings provide an effective way for river regulation and flood control for river regulation.
