[ home port | In shallow water their length shortens and their height increases dramatically. Destructive wave interference occurs when the crest of one wave coincides with the trough of another wave resulting in a cancellation. Higher storm energy in the winter moves sand off the beach and stores it in the nearshore. It is due to: Refraction can be assessed by drawing wave orthogonals, imaginary lines perpendicular to the wave crest.
