A beach undulation (rhythmic topography) is an equilibrium beach form. The water wave energy flux depends upon the refraction of the hydrons (water wave packets), and the angle of the breaking waves is determined by the refraction of the wavelets within a hydron. The refraction of the hydrons and wavelets work together to provide a constant longshore drift of sediments.
