We conducted numerical mixed-size gravel movable-bed experiments using a numerical movable-bed channel capable of simulating motions of flow and gravel. To investigate effects of particle sizes on their motions, contact forces of moving particles exerted in collision with movable bed were measured for each particle size in the experiment. The result showed that relatively large particles received more upward contact forces than those of small particles. We also conducted numerical movable-bed experiments with spheres. Effects of particle shapes on gravel motions were investigated by the comparison between gravel and sphere motions. The result showed that a difference of fractional sediment transport rates of gravel was smaller than that of spheres.
