以黄河下游河床演变特性为基础，提出了漫滩水沙运动及水沙交换的处理方法，探讨了冲淤量沿河宽分布的准二维计算方法，分析了河床横向变化及其对纵向输沙的影响，并提出了相应的模拟方法，在已用实测资料对这几项研究率定的基础上，建立了适用于黄河下游的准二维数学模型，并用黄河１９６９—１９７８年实测资料进行了验算，验证成果表明，计算与实测基本一致，最后计算和比较了不同来水来沙方案对下游的影响。
Based on the evolution characteristics of the river bed in the lower Yellow River, a new method to deal with water and sediment movement and water and sediment exchange in floodplain was put forward. The quasi-two-dimensional calculation method for the distribution of scouring and silting along the river was discussed. Based on the measured data, the quasi-two-dimensional mathematical model applied to the lower Yellow River has been established. Based on the measured data of the Yellow River from 1969 to 1978 The verification and verification results show that the calculation and measurement are basically the same, and finally calculate and compare the impact of different incoming water and sediment programs on the downstream.
