How do wave energy and wavelength influence sediment transport and shoreline morphology?

• A. Wave energy doesn't affect sediment.
• B. Sediment transport independent of wave energy.
• C. Shorter wavelengths always erode.
• D. Higher energy and longer wavelengths transport sediments more effectively alongshore; wave refraction and reflection shape beaches; sediment supply and dissipation determine dune formation and shoreline retreat or progradation.

Answer: (D)
