| 摘 要： | 应用随机理论对Nash单位线进行分析研究，把模型参数Ⅸ看作是随机变量，推导出Nash随机S曲线的公式并应用于沿渡河流域的汇流计算中。应用这种方法模拟降雨径流过程能同时给出出流过程均值和方差。

| Abstract: | Nash unit hydrograph is a method of flow concentration calculation was used widely in flood forecasting and hydrological calculation,but it is random to some extend.In the paper,the Nash unit hydrograph was studied by random theory,the element of the model was looked as a statistic variable,then the formulation of Nash random S-curvewas deduced,whichwas used for watershed flow concentration of the Yandu river catchment.The mean and the variance of the outflowprocess were given by use of the method to simulate the precipitation process as well. |
