The Gulf of Lions shows about 220 km of sandy shoreline delineated by limited rocky headland (such as Cap d’Agde or Saint Clair Hill). The edification of all the present-day barrier beaches is controled by a limited number of mechanisms. They have been quite well understood thanks to field works combining THR seismic survey, geological investigation and coring.

The littoral from Palavas to Aresquiers is a typical barred beach system. I studied when and how this sand barrier arose, how it delineated several lagoons from the open sea and how much the Holocene littoral architecture inherited from the Quaternary geological history.
