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。
Two flood data of the Xiaobei main stream in 1977 were analyzed. A mathematical model of unsteady sediment flow was established to simulate the scour of the river. The flood and sediment process on August 3 was predicted by the coefficient and parameters of flood rate on July 6, and the result was satisfactory.
