Every wave, no matter how strong it seems while rolling in, is followed by a backwash, often nearly as powerful. Figure .1 shows a line in a surging breaker formed when backwash runs into an oncoming wave front. Such a step may be called the backwash step. A backwash vortex formed when the first backwash ran into the wave bore following it. The vortex may properly be called a backwash vortex. Thus, an already weak swash is further impeded in its movement up the beach by interference from the backwash of the wave before. As water oscillations continue, the backwash vortex scours material from the erodible bed, causing a step to grow up gradually. As far as the plunge step is ever caused directly by the plunge of waves, the backwash step so far discussed seems different from it.
