From the synthesis of the malacological data collected from 12 sites in the large flood‐plain of the Seine basin, three main environmental stages have been reconstructed. During the first half of the Holocene, forest environments are prevalent (Seine 1). As early as c. 6.5 cal. ka BP, the first evidence of woodland clearance is observed (Seine 2) and, from c. 3.4 cal. ka BP, the lowlands were largely cleared of trees and are dominated by grassland (Seine 3). This three‐stage development of environmental conditions is consistent with the environmental developments reconstructed from molluscan successions in England, Germany, Luxembourg, Switzerland, Poland, the Czech Republic and Slovakia. Our results highlight anthropogenic disturbance as the key factor in the openness of the Holocene landscape and pinpoint the period between c. 3.6 and c. 2.8 cal. ka BP as a transitional phase of this large‐scale environmental change.

“…It is also observed at Bercy, where a fifth channel is established. This event is well recognized, not only over the whole of the catchment area of the Seine (Chaussé, 1997;Pastre et al, 1997Pastre et al, , 2002Pastre et al, , 2006Gaillard, 1999;Orth et al, 2004;Le Jeune et al, 2005;Chaussé et al, 2006) but also in the Loire Valley (Carcaud et al, 2002) and the Rhône basin (Salvador, 1991;Bravard et al, 1992;Arnaud et al, 2005). In Europe, it has been recognized in the Netherlands (Van Geel et al, 1996), UK (Lewin et al, 2005;Charman et al, 2006), Spain (Thorndycraft and Benito, 2006) and Poland (Macklin et al, 2006).…”

“…BP. This rejuvenation is expressed by the reactivation of old channels or the formation of new erosive features, together with a generalized aggradation of the alluvial plains owing to silty inputs that become increasingly regular from the latter part of the sub-Boreal on (Pastre et al, 1997(Pastre et al, , 2002(Pastre et al, , 2006Gaillard, 1999;Orth et al, 2004;Le Jeune et al, 2005). This instability, which follows the emergence of wetter global conditions, is expressed in the Jura by the Chalain lake transgression (Magny, 1999(Magny, , 2004, and occurs in a context of generalization of agro-pastoral activities Leroyer and Allenet, 2006;Pastre et al, 2006).…”

Holocene history of the River Seine, Paris, France: bio-chronostratigraphic and geomorphological evidence from the Quai-Branly

et al. 2008

International audienceBio-chronostratigraphic observations compiled from Quai-Branly in Paris (France) and their comparisonwith previous studies in the Paris Basin allow documentation of the morphodynamic evolution of theRiver Seine during the middle and late Holocene. This history begins in the Boreal (between 9500 and 8850cal. BP), with the deposition of tufa, expressing a stabilized river bed. During the second part of the sub-Borealthe water-table was low. At the beginning of the sub-Atlantic (towards 2800/2700 cal. BP), alluvial dynamicsincrease, as is recorded elsewhere throughout the Paris Basin. At the beginning of the second part of the sub-Atlantic (around 2000 cal. BP), flood dynamics persisted at a lower intensity. Human occupation occurred fromthe fifth century AD. Before or around the beginning of the seventeenth century AD, a natural levee was built,indicating the progressive attachment of the Quai-Branly area to the floodplain. The hydrodynamic evolutionof the River Seine observed at the Quai-Branly site is similar to that recorded in other river valley floors of theParis Basin. This evolution appears to be in response to global climatic changes rather than to variations inducedby human activities
