Restituer les corridors fluviaux d’après les relevés stratigraphiques des diagnostics archéologiques : exemple de la vallée de la Seine dans le Nogentais

Abstract : Since 1995, fields of the Nogentais area, and more specifically those from the municipalities of Pont-sur-Seine, Villeneuve-au-Châtelot and Périgny-la-Rose (Aube department), have been extensively archaeologically excavated prior to the exploitation of the limestone gravels of the Seine river. These operations totaled a diagnosed surface area of just over 331 hectares and more than 4,000 trenches documented in various ways with regard to the sedimentary deposits brought to light. Two main trends can be observed for the limestone gravels, either present directly below the ploughing horizon or under a thick layer of fine material. These trends illustrate the contrasting morphology of the gravel roof within the valley and the presence of palaeochannels. This article proposes a review of the sedimentary data acquired between 1995 and 2015 in order to map the river corridors within this space. It will eventually make it possible to discuss their impact on former land occupancy (preferential occupation of gravel domes such as bank development) and conservation of the remains (erosion and deposition processes).
