“…5 and Table 1), suggest that at some stage the rivers lost the capacity to transfer sediment to the lower foreshore (similar to what is observed at present), probably due to the sea level rise. The importance of the swash zone location and its shift in sympathy with mean sea level change has been observed in several regions where sediment supply and wind speed and direction are otherwise favourable to dune formation (e.g., Arens, 1996;Hesp, 2002;Ruz and Meur-Ferec, 2004).…”

In Armação de Pêra Bay, southern Portugal, environmental changes during the Holocene can be interpreted based on the morphological and sedimentological similarities between older geomorphic features (cemented beach and dune rocks) and present coastal features. Using knowledge of the present beach and dune processes, we propose a two-step model for the evolution of Armação de Pêra Bay. First, during the rapid sea level rise between about 8 800 and 6 600 yr cal BP, the bay changed from a positive to a negative budget littoral cell and transgressive dunes formed, favoured by drought conditions. At about 5 000 yr cal BP, during a sea level maximum, beach width was less than the critical fetch and dunes stabilized and underwent cementation during the wetter Atlantic climatic event. The second phase of dune accumulation started at about 3 200 yr cal BP, due to a regression of sea level during which the bay changed back to a positive budget littoral cell in which beach width was greater than the critical fetch. Currently, the beach width is less than the critical fetch, dunes are inactive, and the sedimentary budget is negative due to sediment storage in local river systems.

“…À l'inverse, le profil surbaissé du haut de plage/pied de dune à la fin de l'hiver renforce l'action érosive des tempêtes printanières. Ainsi, comme l'ont montré plusieurs auteurs, la morphologie dunaire, et à travers elle l'ensemble des processus qui agit sur les échanges sédimentaires entre la plage et la dune, contrôle en partie l'action érosive des tempêtes (Short et Hesp, 1982 ;Davidson-Arnott et Law, 1990 ;Sherman et Bauer, 1993 ;Morton, 2002 ;Aagaard et al, 2004 ;Battiau-Queney, 2004 ;Ruz et Meur-Ferec, 2004, Saye et al, 2005Anthony et al, 2006 ;McLean et Shen, 2006 ;Pye et Blott, 2008 ;Sabatier et al, 2009) Bruun (1962) peut s'appliquer dès lors que les transferts sédimentaires transversaux ne sont pas influencés par d'autres dynamiques. Ainsi, pour les profils 1 et 2 de la plage du Vougot, les volumes érodés à la dune semblent bien alimenter la haute plage intertidale, à la différence de la radiale 3, pour laquelle les deux sections du profil sont déficitaires ( fig.…”

“…Reflective beaches are much less favourable for Aeolian transport (Hesp, 1999). The dune building process mostly results from the impact of recurrent storm periods that lower the beach profile, especially at the HWM (Hallé gouë t, 1981; Ruz and Meur-Ferec, 2004). The beach profile becomes dissipative, as it was the case in Brittany in springs of 2010, 2013 and 2014: a thick foredune was formed in summer 2010 at Guisseny ( Fig.…”

International audienceHolocene coastal dune formation under a continuously rising sea level (SL) is an abnormal response to increasing storm frequency. The aim of this work is to understand the coastal sedimentary budget and the present-day sand starvation, controlled by climate and man. Dating in Brittany shows that Aeolian deposition initiated from ca. 4000 cal BP, with the slowing down of the SL rise. Pre-historical dunes appeared here from ca. 3000 cal BP, without SL regression. After, further building phases recycled the same stock of sands. Historical dunes I developed from ca. 350 AD. Major storms between 900 and 1200 AD resulted in the construction of washover coastal ridges, the Historical dunes II. A part of the sand was evacuated offshore. From ca. 1350 AD, the pre-existing ridges are reworked forming the Historical dunes III, leading to rapid coastal erosion and inland drift. Holocene dunes with a rising SL constitute a temporary anomaly, mostly forced by man, soon erased by storms in Brittany
