Resistance to reversing flows over movable beds
Experiments carried out with bed materials of various densities showed that ripples generated on bed surface are essentially similar to those of unidirectional flow, but their shapes are reversed as to conform with flow direction; resistance of such bed depends on grain Froude number and grain Reynolds number; importance of viscosity in determining resistance is emphasized; resistance function at instant of peak velocity is determined for conditions of movable-bed tidal models; relationships determining resistance of movable bed for tidal model conditions are presented.
