Abstract
This paper describes a Large Eddy Simulation of steady uniform flow in a symmetric compound channel of trapezoidal cross-section with flood plains at a Reynolds number of 430,000. The simulation captures the co mplex interaction between the main channel and the flood plains and pr edicts the bed stress distribution, velocity distribution, and the sec ondary circulation across the floodplain, The results are compared wit h experimental data from the SERC Flood Channel Facility at Hydaulics Research Ltd, Wallingford, England.
