In the curved compound channels, there are secondary flows induced by centrifugal forces and horizontal vortices at the junction of main channel and flood plains. We conducted experiments to measure the horizontal vortices and the velocity field of flow. A quasi-three-dimensional computation using SDS-Q3D model was performed, and the results were compared with the experiments. The result shows that this model is appropriate to simulate the entire flow field except for the inner junction of the main channel and the flood plains where 3D turbulence associated with boils is predominant.
