OF THE ANSEOBSERVATIONS ON THE FILLING DE L'AIGUILLON (FRANCE)

Abstract

The coast of Vendee, south of the Pointe du Grouin du Cou, has been the scene of a fast morphological evolution: the coastal bar of La Tranche, the spit of Arcay with ridges and furrows, and the bar of the Pointe de l'Aiguillon. The rather quick advance of the latter since the Middle Ages has narrowed the opening of the Anse de l'Aiguillon and thus facilitated the deposit of sediment in the Anse, which has reduced the size of the bay. A few centuries ago this bay went further east and north.
