Abstract : The two equation turbulence model based on the k-epsilon closure scheme was developed to simulate the flow and turbulence characteristics of open-channel flows through nonemergent vegetation. Once the performance of the model was verified, the flow structure of vegetated open channels was numerically simulated. Simulated rigid and flexible plants were used to validate the model. Finally, dimensional analysis allowed identification of the dimensionless parameters that govern suspended sediment transport processes in the presence of vegetation, and thus helped in the design of numerical experiments to investigate the role of different flow properties, sediment characteristics, and vegetation parameters upon the transport capacity.
