| 摘 要： | 本文系统地归纳与介绍了基于随机理论的现代汇统计算方法——地貌气候瞬时单位线理论,在对该单位线理论进行概率释义的基础上建立了四级河网流域的地貌气候瞬时单位线数学模型。在模型建立过程中进行了严密的数学推导,对模型中各参数的定义及求算方法也作了详细说明。最后本文以安徽省滁州径流实验流域为例进行了参数求算、单位线确定和汇流计算。通过比较流域出口断面的计算洪水流量过程和实测洪水流量过程验证了地貌气候瞬时单位线数学模型的有效性。

| Abstract: | On the basis of the stochastic theory, a modern watershed flow concentration method-Geomorpho-Climatic Instantaneous Unit Hydrograph (G. C. IUH) Theory-is introduced systemly in this paper. We set up a 4-order river system G. C. IUH model ba ed on the probability explanation of G. C. IUH after the strictly mathematical deduction. This paper also provides the parameters definition and calculation method in the model. We take the Chuzhou Experimental Basin in Anhui Province as an example to determine the G. C. IUH and predict the flood processes at the basin outlet. The effect of model is testified by the comparison between the calculated result and observed result. |
