| Abstract;Sediment reworking and channel bed stabilization processes were observed along Oyabu Creek (catchment area:5.2km2), a steep, gravel bed mountain stream in Miyazaki, Kyushu, Japan after major aggradation induced by a typhoon in 1993. Using 7 years of field observation the authors showed the relationship among sediment storage patterns and flow rate-sediment discharge, and estimated the time required to reach a stabilized channel bed after a major disturbance. In particular they examined changes of the threshold conditions that control sediment adjustment and the relaxation process after a major disturbance, and the sensitivity of channel bed to changes. |
