Transportation and deposition processes produce distinctive coastal landforms (beaches, recurved and double spits, offshore bars, barrier beaches and bars, tombolos and cuspate forelands), which can be stabilised by plant succession. Wave energy is dispersed in the bays; deposition is maximum. Hydraulic action is the predominant process.
