本文就低含沙洪水与高含沙洪水对河床的冲淤模式进行了描述，在对洪水冲刷河床的力学机理进行分析的基础上，初步建立了来水来沙与河床基本相互适应的条件下洪水冲刷深度与来水来沙的关系，并用黄河干支流资料进行了讨论与验证。该公式考虑因素简单，计算方便，同时适用于低含沙与高含沙洪水，可以用来估算洪水对黄河干支流河床的冲刷情况
This paper describes the scouring and silting modes of low silt flood and high silt flood on the riverbed. Based on the analysis of the mechanics mechanism of flood scouring riverbed, Flood depth and the relationship between water and sand, and the Yellow River tributaries information for discussion and verification. The formula is simple and easy to calculate, and is suitable for floods with low sediment concentration and high sediment concentration. It can be used to estimate the flood scouring effect on the mainstream of the Yellow River
