Keywords:Velocity of Sediment Transport, hydraulic roughness, PIV/PTV

Many researchers focus on sediment transport through fixed bed made from concrete or soft rock because of sand -wear phenomena. However, we cannot take care with surface roughness with sediment transport. In this research, I focus on changing hydraulic roughness with sediment transport. I conduct flume experiments to measure flow and sand movement velocity distribution with PIV/PTV, and indicate the discussion point of changing hydraulic roughness.
