Abstract:
Based on the current research situation of soil water infiltration characteristics, the research progress of impacts of soil moisture variation on rainfall runoff was discussed from three aspects, including the initial moisture content, spatial variation of soil moisture, and application of soil moisture data in hydrological model. The existing problems and research direction of soil moisture variation and rainfall runoff were discussed. The spatial and -temporal variations of soil moisture were the hot and important research topics in the study of rainfall-runoff and its model simulation. The real-time variation of soil moisture obtained from different experimental measurements and model simulations and its response to subsurface flow and preferential flow are the important research aspects in future hydrology study.
