| 摘 要： | 黄河下游游荡型河道河术逐年淤积抬升的众多影响因素中，高含沙洪水起着十分重要的作用，本文根据概化模型试验结果和野外实测资料，分析了高含沙水流游荡型河道滩槽冲淤演变特点，特别提出窄深河槽一方面由高含沙水流自身塑造，另一方面游荡型河道中由高含沙水流塑造的窄深河槽又表现出相对的不稳定性。

| Abstract: | The floods with high sediment concentration play a most important role in the fluvial processes of the Lower Yellow River. Based on the results of the model experiment and the field data, the characters of the aggradation and degradation of the main channel and the floodplains during a flood with high sediment concentration have been observed and the mechanism of the formation of the narrow deep channel has been analyzed. It also has been pointed out that the narrow deep channel formed during the flood is much unstable. |
