【摘要】：為了加強(qiáng)對(duì)中小河流的洪水管理,分別構(gòu)建中小河流域水文學(xué)模型、Mike11模型以及Mike21FM模型,運(yùn)用Mike Flood對(duì)一、二維模型進(jìn)行耦合計(jì)算,對(duì)中小河流進(jìn)行洪澇風(fēng)險(xiǎn)分析。以徐州市豐縣復(fù)新河左岸地區(qū)為例,建立洪水演進(jìn)數(shù)值模型,分析復(fù)新河的防洪能力以及不同暴雨情況下研究區(qū)內(nèi)澇情況。結(jié)果表明:研究區(qū)域基本滿(mǎn)足20年一遇防洪能力,部分中小河流排澇能力不足,導(dǎo)致部分地區(qū)內(nèi)澇較嚴(yán)重。
[Abstract]:In order to strengthen the flood management of small and medium-sized rivers, the hydrological model, Mike11 model and Mike21FM model of small and medium-sized river basin are constructed respectively. Mike Flood is used to calculate the coupling of one-dimensional and two-dimensional models, and the flood risk analysis of small and medium-sized rivers is carried out. Taking the left bank of Fuxin River in Fengxian County of Xuzhou City as an example, a numerical model of flood routing was established to analyze the flood control capacity of Fuxin River and the waterlogging situation in the study area under different rainstorm conditions. The results show that the study area basically satisfies the flood control ability once in 20 years, and the drainage capacity of some small and medium-sized rivers is insufficient, which leads to serious waterlogging in some areas.
