| 摘 要： | 单位线方法在水文计算及洪水预报中得到了广泛的应用，至今仍然是汇流计算的重要工具。以沿渡河流域为研究背景，分别采用分析法及矩法推求了该流域的时段单位线，并分别用这两种单位线模拟了该流域的同次洪水过程，模拟结果表明分析法得到的单位线更加适合该流域的洪水计算。最后，在详细分析两种方法误差来源的基础上，提出了相应的改进措施。

| Abstract: | Unit hydrograph method that has been widely used in hydrologic computation and flood forecasting is still an important tool for the computation of flow concentration.In this paper,the Yandu River basin is taken as study background.Two unit hydrographs derived separately by the analysis method and the moments method are used to simulate a flood hydrograph in this basin.The results show that the unit hydrograph derived by the analysis method is more suitable to the flood computation of the Yandu River basin.Finally,some improvement measures for each method are proposed based on the errors cause analysis. |
