sediment concentrations decreased again in a logarithmic manner. New soil loss processes will likely follow a similar pattern during the next heavy rainfall event.
Type III sediment hydrographs were generated in the Xujiawan watershed in response to all types of rainfall events. Similarly, with the exception of event 000817, the same pattern of Type III was generated on the hydrographs in Kunniushan watershed, despite the smaller watershed area. However, no events produced the typical logarithm-decreasing hydrograph in Sangshutu watershed. In addition, the sediment hydrographs generated in the Xujiwan watershed during IM-type rainfall events were not compound, but were similar to the patterns on the hydrographs generated by event 000817 in Kunniushan watershed and all of the events in
