摘　　要：分析了１９７７年小北干流的两场洪水资料，建立了非恒定流泥沙数学模型，模拟该河段的揭河底冲刷。并用７月６日的洪水率定系数和参数预测了８月３日洪水的水沙过程，其计算结果令人满意。This paper analyses the 1977 data of two floods obtained from Xiaobei trunk river course on the basis of which a mathematical model for the non constant flow sediments is established to simulate the scoring of the river bed in that section by the floods. Also the coefficients and parameters of flood waters of July 6 in that year were used to predict the process of flood water and sediment of August 3 of that year. The calculated results are satisfactory.
