A beach equilibrium model is developed that treats the outer (shorerise) portion of the profile independently from that of the inner (bar-berm) portion. The two portions are matched at the breakpoint-bar. The partitioning of the profile in this way is consistent with the different forcing modes on either side of the breakpoint. This formulation utilizes beach profile data not previously available. It is shown that both portions of the profile are well fitted by curves of the form h=Ax/sup m/, where h is positive downward and x is the positive offshore coordinate. Surprisingly, the value of m approximately=0.4 is nearly the same for shorerise and bar-berm and does not change significantly with seasonal beach changes (summer/winter). The principal difference between seasonal profiles is that in winter (higher waves) the breakpoint-bar is deeper and farther offshore while the berm crest is displaced landward. Thus the changes in seasonal equilibria are manifested by simple, self-similar displacements of the bar-berm and shorerise curves as a consequence of changes in surf zone width and O(1) variations in the factor A.
