A flume experiment on sediment transport with flexible, submerged vegetation
Vegetation affects sediment transport by obstructing the flow and changing the turbulence characteristics. Common sediment transport equations are not applicable to situations with submerged vegetation. A laboratory experiment was carried out in which flow, turbulence characteristics and sediment transport were measured in a 80 cm wide flume with a 15.85 m long section of 18 cm high, artificial, flexible, submerged vegetation in a sand bed. Measured profiles of velocity and turbulence were analysed and simulated with a 1DV numerical model to obtain estimates of the bed shear stress. Results show a reduction of the bed shear stress with about 80%, and an increase in sediment transport rate compared to a case without vegetation.
