基于MIKE FLOOD模型的漫溢洪水演进研究

Research on overflowing flood routing based on MIKE FLOOD model

丹麦水力研究所开发的MIKE FLOOD模型是在国内外大量项目实践中发展起来的,在中国洪水计算领域得到广泛应用。本文以北沙河为研究对象,搭建了主河道一维和淹没区二维的侧向耦合模型,考虑了阻水建筑物及过水涵洞的影响,模拟漫溢洪水的演进过程。

MIKE FLOOD model developed by Danish Water Resources Institute is developed in a lot of domestic and foreign projects. It is applied widely in the field of flood calculation in China. In the paper, Beisha River is adopted as a research object to establish a lateral coupling model of main river channel one-dimension and submerged area two- dimension. The influence of water-resistant building and water culvert are considered for simulating the overflowing flood routing process.
