Understanding the developing mechanism of an outer bank cell is benefit for making full use of its important function to protect the concave bank from erosion in alluvial river bends. This study employs a bend flume experiment and a 3D renormalized group with (kappa -epsilon) closure numerical model to investigate outer bank cells. Results obtained from the physical experiment and numerical simulations elucidate that (1) outer bank cell does not develop at the same time as the occurrence of center region cells, but it often yields later; (2) in sharply curved bends, outer bank cells are originated from the mutual effect of the centrifugal force created by channel bends and the pressure differences due to transverse water surface slopes; (3) a parameter (beta) was derived and also testified effectively for quantitatively evaluating the occurrence of an outer bank cell and influence of flow parameters on the development of outer bank cells in sharply curved open channel bends.
