Description :
This paper addresses spatial and temporal variability in runoff and erosion processes caused by topographic and hydrological variations. Research efforts included monitoring natural runoff and sediment production in the field at different hillslope positions and recreating specific surface hydrologic conditions in a controlled laboratory setting. The results show a close linkage between surface moisture condition and erosion process, and consequently, the dominant sediment regime. These approaches provide a basic framework toward the understanding of hillslope scale erosion processes that would eventually be used to build a physically based erosion prediction model.
