摘要
以海城河为例,针对现代城市发展过程中城市河道由自然渠化生态的过程导致河槽糙率变化问题,分析其对河道行洪能力的影响,并利用一维河网模型MIKE11建立了海城河城区段水动力模型,分析生态河道规划前后不同糙率情况下海城河现状堤防的防洪能力,为海城河防洪规划提供理论依据。
The roughness of river channel changes as the river changes from canalizated system to eco-environmental system,which affects the capacity of river flood discharge.Taking Haicheng River for an example,the water dynamic model is established based on MIKE11.The flood control capacity of dyke is analyzed under different roughness in ecological channel planning.Thus,it provides theoretical basis for flood control planning of Haicheng River.
