Description	Other An investigation on three-dimensional turbulent structure including secondary currents in compound open-channel flow is very important in basic hydraulics as well as practical engineering to verify the friction law of flow and sediment transport. In this study, secondary currents and three-dimensional turbulent structures in compound open channels were revealed experimentally by making use of a fiber-optic laser Doppler anemometer. Strong inclined upflow which is associated with a pair of longitudinal vortices is generated in a junction region between a main channel and a flood plain. Primary mean-flow field and turbulent structure are affected by the secondary currents.
