State whether the following is true or false.
Beach cusp spacing scales with the swash excursion length.

  • A.True only at large scales
  • B.False only at small scales
  • C.True
  • D.False

Answer: C

Larger swash under bigger waves produces correspondingly wider cusps. The regularity of the spacing is a hallmark of a self organising process. No external forcing sets the spacing directly. The pattern emerges from the swash itself.
