面雨量不均对GIUH非线性改正探讨

Nonlinear Adjustment Based on Asymmetric Areal Rainfall on GIUH

地貌单位线(GIUH)基于流域地貌特征和概率方法,在我国许多地区得到广泛应用。针对面雨量分布不均问题,通过分析初始概率的变化,考虑GIUH的非线性改正,并用实际资料进行了验证。

Geomorphologic instantaneous unit hydrograph (GIUH), based on the geomorphologic characteristics and probability method, has been widely used in China. In accordance with asymmetric areal rainfall, this paper gives a nonlinear adjustment on GUIH in view of initial probability, which has been tested with the practical data.
