Description :
Here, the AA. report on successful laboratory experiments (Hull University, England) that elucidate flow structure in one constant-width bend and a second bend with an outer-bank widening. The experiments were performed with both a flat immobile gravel bed and mobile sand bed with dominant bedload sediment transport. In conclusion, the experiments elucidated three distinct processes of flow separation common in sharp bends : flow separation at the inner bank, an outer-bank cell of secondary flow, and flow separation and recirculation in an outer-bank widening.
