The edification of the littoral systems in the Gulf of Lions

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.

Holocene story of the Palavas – Aresquiers barrier beach

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.
