流域汇流系统随机不确定性研究

Study on random uncertainty in the system of watershed flow concentration

针对汇流过程存在的随机不确定性因素,假定入流过程对均值的偏离量具有高斯白噪声的特性,利用相关函数理论对随机汇流系统进行分析研究,确定出流过程的均值和均方差。研究结果表明,利用随机汇流模型解决汇流问题是可行的。

There are many random uncertainty factors in the process of flow concentration.Assumed inflow process has Gaussian white noise characteristics for deviation value of mean.Random flow concentration system with correlation function theory to get mean and mean-square deviation in the process of outflow are analyzed.The results show that it is feasible to solve flow concentration question with random flow concentration model.
