| 摘 要： | 黄河下游河道逐年淤积抬高，河道断面萎缩，过流能力降低，漫滩流量大幅度减小，致使黄河洪水出现小流量、高水位、大险情的特点．通过对黄河下游的泥沙淤积规律的认识，以黄河下游洪水不同时期水位的变化、洪水传播时间的变化以及漫滩流量和削峰作用的变化来论述下游河道淤积对洪水特性的影响．

| 关 键 词： | 黄河下游 河道淤积 削峰系数 |

| Abstract: | Because of increasingly river channel silting,gradually shrunken channel,decreased discharge capacity and markedly lowered flood plain storage,the food of Yellow river,caused by low flow,can lead to high water stage and huge danger.Therefore,this paper discusses the properties sediment accumulation in the downstream part of the Yellow river and the effect of the down stream river channel silting on the flood figures by studying the change of the flood stage with time,the change of flood travel time and the change of the plain' s ability to cut down the flood peak discharge. |
