摘　　要：本文分析了1977年小北干流的两场洪水资料,计算了揭河底冲刷。对洪水采用非恒定流计算,对泥沙采用不平衡的输移方式计算,建立了数学模型,用7月6日的洪水率定系数和参数,然后预测8月3日的洪水,得到的计算结果比较令人满意。This paper is analysed the data of two flood about Xiaobeigan River in 1977. Calculated erosion of exposing bed river. The model is built with unconstant method of water and unbalance method of silt during flood season. The parameter and the coefficient are calculated with the flood data in July 6. And then forecasted the flood data in August 3. The data calculated is pleased.
