Beach Cusps – How Do they Form?

Beach cusps are formations of the beach (as the name implies) appearing usually after or at some stage in storms. These formations are unique because of their regular and uniform spacing. There are two theories assumed of their formation – first being the “standing edge” theory stating the interactions amid normal waves that approach the waves of ‘edge’ and shore forming in perpendicular to the seashore. Interactions amid the waves create the usual-spaced points of distinct wave intensity. Second is the self-organization theory which states – the cusps are usual outcome of the interactions of sand, wave and current with passage of time forming the feedback loops. Several scientists think it to be the unison of both theories.
