依据水沙运动基本方程 ,结合黄河水沙特点 ,建立了黄河下游河道一维恒定不平衡输沙数学模型。用黄河下游1960～ 1965年、1965～ 1974年、1974～ 1996年 3个时段的水沙资料对模型进行了检验 ,验证结果与实际基本相符。模型用于小浪底水库运用方式研究中 ,进行了多种方案的计算。
According to the basic equations of water and sediment movement and the characteristics of sediment and sediment in the Yellow River, a mathematical model of one-dimensional constant unbalanced sediment transport in the lower Yellow River was established. The water and sediment data of three periods from 1960 to 1965, from 1965 to 1974 and from 1974 to 1996 in the lower reaches of the Yellow River were used to test the model. The results of the validation are in good agreement with the actual situation. Model for the study of Xiaolangdi reservoir operation mode, a variety of programs are calculated.
