Gravity has a significant role to play in coastal processes. That energy is evenly spaced out in the deep water, but because of refraction, the energy of the waves is being focused on the headlands. Waves approach the shore at some angle so the inshore part of the wave reaches shallow water sooner than the part that is further out.
