The data on flow events observed at gauging stations and experimental plots, all located in the Dalihe watershed (north of Shaanxi Province), are presented. At the watershed scale, the scouring effect takes predominance first but is subordinate to the downstream dilution with a further increase in spatial scale. Therefore, the AA. propose a sediment-yield model, which is neither a physical-based model nor a regression model. This model, with only 2 variables (runoff depth and drainage basin area) and 2 parameters, can fairly accurate prediction of event sediment yield with a good efficiency if small events with runoff depth lower than 1 mm are excluded
