Study of Effect on Sediment Flow Characteristics from Vegetation Growth

Abstract:

Form 12 groups times flume experiment of No-plant and plant height of 2,5,9cm simulation, the order of effect that sediment flow characteristics with vegetation growth was investigated. The results show that the vertical velocity distribution of sediment flow with plant is no longer consistent with logarithm distribution with no plants in sediment flow, but for the "S"-type distribution. The Re increases with the decrease of plant height and the increase of flow. The roughness decreases with the increase of plant height and flow.
