Description

<p> In this paper, thought experiment and flume experiments have been taken in order to indicate the characteristics of sediment transport and flow distributions. Especially, the mechanisms that the sediment movement take influences to flow structure are focused on.</p><p> PIV by using fluorescent pigment as tracer can measure flow velocity distribution in the condition that water flow including sediment transport. And I measure the sediment particle motion by PTV. These data give informations about characteristics of flow velocity distribution near bed. Flow velocity change at the depth of the water whole, and Reynolds stress decreases under the case that flow include suspended sediment.</p>
