Sediment control along river is very important for river management. These days, countermeasures to deal with rotational degradation, e. g. placing sand at the downstream of the dam, have been taken in some rivers in order to restore the continuity of sand interrupted by dam. To indicate significance of artificial sediment supply in river, we need know where supplied sediment deposit, how sediment supply let river morphology change, and so on. Therefore, we focus on the sediment transport on the bars which is typical landscape of river. We took the experiments to estimate sediment discharge on the bar and to indicate differences between sediment transport on the bars and on the flat bed. As results, characteristics of sediment discharge and sediment transport on the bars are shown.
