黄河下游游荡型河道河床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 Among the many influencing factors of silting uplift in the estuarine channel of the lower reaches of the Yellow River, high silt flood plays a very important role. According to the generalized model test results and field measurements, In particular, it is proposed that the narrow and deep fluvial channels are shaped by the high-sediment flow on the one hand and the narrow-fluvial channels formed by the high-sediment flow in the wandering channel also exhibit relative instability
