| 摘 要： | 通过物理模型试验对松花江某平原漫滩河段的沿堤防洪水位进行了研究,对主槽和滩地阻力采用了不同的模拟方法,在达到模型相似的基础上,试验量测了水流边界沿低水位随流量的变化关系。研究表明,因河段内阻力因素复杂,边界沿堤水位与同断面主槽水位差别最大可达0.3m。

| Abstract: | In this paper,flow boundary water levels along flood embankments in flood plain reach of the Songhuajiang River are studied by the physical model. Different modeling methods to the roughness of the flood plain were used. Based on the similar model,the relationships between the water levels along the flood embankments and the discharges are measured. The experimental results show that due to the complex resistance in the reach,the water levels along the embankments are different to the levels of the main channel at the same section,and the maximum difference between the two places is 0.3 m. |
