加里宁－米留柯夫型流域地貌汇流模型

Geomorphological watershed concentration model with Kalinin-Milyukov type

本文根据概念性流域地貌汇流模型的一般理论，建立了加里宁－米留柯夫型流域地貌汇流模型、推导了三级、四级和五级流域的瞬时单位线，并分析了模型参数对瞬时单位线的影响．用内罚函数法估计模型参数．通过实例检验，模型拟合精度较高．

Geomorphological concentration model with Kalinin-Milyukov type is developed according to the concept of geomorphological watershed concentration model.The instantaneous unit hydrographs (IUH) for third-order, fourth-order and fifth-order basins are derived with the analysis of the effects of the model parameters on the IUH. The interior-penalty-function method has been applied for the estimation of the model parameters. The result of the test for the proposed model shows that the model accuracy is highly acceptable.
