摘要:
ABSTRACTPlane beds that replace small bedforms (e.g. ripples) on the backs of subaqueous dunes are dynamically similar to upper‐stage plane beds. Local bed shear stresses at the position on dunes where plane beds develop may be two to three times larger than on a completely plane bed under the same general hydraulic conditions. These observations help explain the transition from dunes to a wholly upper‐stage plane
