摘要
淮河干流浮山至洪泽湖段河道呈倒比降,入湖河段河道分汊,湖区支流入汇众多,流态复杂。本文针对该河段的特点,建立了淮河干流浮山至洪泽湖出口段一、二维耦合洪水演进数学模型,模拟了2003、2007年本段洪水演进的过程。结果表明计算值与实测值吻合较好,模型计算精度较高,可为浮山以下河道不同治理方案的研究提供分析计算平台。
The channel of the main stream of Huaihe River from Fushan to Hongze Lake is inversely sloped with branched channel of the river course flowing into the lake and many tributaries inflowing into the area of it, and then the flow regime therein is quite complicated. Based on the characteristics of the river course, a 1 -D and 2-D coupled numerical model for the flood routing is established for the stream of Huaihe River from Fushan to Hongze Lake ; with which the flood routings of 2003 and 2007 for the river course are simulated. The results show that the values from the calculations are basically coincided with those from the actual observations, and therefore, the model has a higher precision and can provide a platform for the analysis and calculation within the study on various schemes for the treatment on channel of Huaihe River from Fushan to Hongze Lake.
