This paper details a high-resolution record of French Atlantic coast extreme wave events using a multi-proxy analysis of dated sedimentary deposits. Two lagoons 1) the Petite Mer de Gâvres and 2) the Traicts du Croisic were chosen to identify damaging storm events from the last 300 years with Beeker sampling, 210 Pb and 137 Cs dating and sedimentary analysis. Using two new geochemical proxies in the French Atlantic coast, Sr/Fe and Ca/Ti, shows that several storminess events are reported in the nine cores drilled. By correlation with historical
Abstract. This manuscript reviews more than 19 691 French historical documents from 14 French archive centers. The results show that 101 extremes storms were recorded including 38 coastal floods. Coastal hazards have forced societies to adapt and develop some specific skills, lifestyles and coping strategies. By analysing the responses of past societies to these hazards, useful ideas may be (re)discovered by today's communities in order to enhance the ability to adapt and develop resilience. Similarly, a thorough knowledge of past climate hazards may allow our societies to recreate a link with territory, particularly through the (re)construction of an effective memory of these phenomena.
Abstract. This paper reviews more than 19 691 French historical documents from 14
French archive centres. To assess data from historical documents, a method
has been applied that leads to a record of 101 extreme storms with damage,
including 38 coastal floods. Thus, the results show periods of increasing and
decreasing storm frequency. These periods are examined. Furthermore, coastal
hazards have forced societies to adapt and develop specific skills,
lifestyles and coping strategies. This paper analyses some responses of past
societies to these hazards. By doing so, useful ideas may be (re)discovered
by today's communities in order to enable us to adapt and develop resilience.
Similarly, a thorough knowledge of past meteorological hazards may allow our
societies to recreate a link with territory, particularly through the
(re)construction of an effective memory of these phenomena.
