Those beaches offer diverse opportunities due to the tombolo formation. The scope of this paper is to further explore this "equilibrium beach" concept in crenulated bays, as a long-term tool for beach nourishment projects. 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.
