Non‐uniform flows in a compound open‐channel: assessment of a hybrid RANS‐LES approach

Abstract Overbank flows in rivers, also termed compound open‐channel flows, are rarely uniform in the streamwise direction. Flow non‐uniformity involves transverse currents directed from the river main channel (MC) to adjacent floodplains (FPs) or vice versa. Depending on their direction and magnitude, the transverse currents can laterally displace the planform shear layer that forms at […]
