Abstract

Runoff is a crucial process of water cycle and the related research is also important for hydrology. In this study, an experiment of artificial rainfall runoff was conducted on the Linmingguan Test Base of Hebei University of Engineering, China. The results show that the typical rainfalls runoff process in flood season and non-flood season are different on the same slope units; the initial time of runoff yield, the peak time & discharge and recession hydrograph of surface runoff and interflow are various on different slope units. This research can sustain development of principle analysis of runoff yield and concentration and provide technical support for parameter optimization of hydrological model in unsaturated zone of North China.
