Abstract: Results are presented of a computational study of turbulent free surface flow in a meandering two-stage channel flowing in overbank mode. The three dimensional Reynolds Averaged Navier-Stokes equations were solved using an operator splitting technique with a linear constitutive law employed for the turbulent stress-strain relationship. The computational results are compared qualitatively with experimental measurements. Comparisons are drawn for the mean flow field, the turbulence kinetic energy and the water surface elevation. The important mechanisms are highlighted as well as the models ability and inability to capture them.
