摘要
根据黄河等河流的实测资料，分析来水来沙大小及其过程对河床演变的影响，提出断面形态与来流大小、过程的定量关系。以黄河为例，探讨了水沙搭配对河道冲刷与淤积的作用。
The effect of the magnitude and process of water and sediment inflow on the fluvial process is analysed, based on the field data in the lower Yellow River. The relationship of water inflow and channel geometry is given. The riverbed changes with the flow and sediment are suggested.
