Description :
The aim of this study was to clarify the behavior of the supplied sediment in headwater channels based on experimental sediment release in the Hirudani experimental watershed located in central Japan. The specific objectives included observing changes in the bedload rate for various grain-size fractions during a sediment-supply event, and elucidating the influence of the grain-size distribution of the bed-surface material and the bed forms on the bedload rate. The results provide information on the sediment accumulation and sorting processes after episodic sediment release in gravel-bed rivers.
