According to a series of data collected from the yearbook of the water and sediment of the Yellow River, the different indices of representative channel depositional dynamics have been analyzed. Be enslaved to the above mentioned depositional dynamics, the sedimentation rate on channel bed is different among the three channel pattern reaches. In addition, the sedimentation rate on braided channel bed evidently depends on the variation of discharge, and decreases with increasing discharge.
