摘要 探讨了在非线性的框架下河网结构对流域水文响应的影响,通过考虑水动力参数空间变化的非线性来构建流域地貌瞬时单位线并进而分析对水文过程的影响。以长江三峡区间沿渡河流域为例,计算表明提出的方法能获得较高的计算精度。 Traditional method to study geomorphology instantaneous unit hydrograph (GIUH) was based on the hypothesis of the velocity of flow is spatially invariant. Considering the unreasonableness of this hypothesis,a new method, which based on the spatially variational hydrodynamic parameters,is presented to study GIUH. The example is given in order to test and verify the new method.
