Abstract :
Based on the flume experiments with aluminum cylinders simulating rigid vegetation and the laser Doppler velocimetry, the velocity distribution of open channel flows without vegetation, with submerged and emergent vegetation are obtained. Combined with the sediment transport rate formula and the comparison of velocity distribution in vegetated flows with that of non-vegetated flows, the analysis illuminates that the submerged and non-submerged vegetation may reduce the transport rate per unit width of bed load and suspended load respectively.
