Études géoarchéologiques et archéobotaniques du comblement de la canalisation du site de la Rue du Ruisseau à Grand (Vosges, Lorraine, France)

International audience; The ancient urban area of Grand (Vosges, Lorraine, France) is characterised by numerous hydraulic infrastructures including a canalisation, crossing the ‘Rue du Ruisseau’ site, which has been in the focus of multidisciplinary investigations. Stratigraphic study and characterisation (sedimentology and micromorphology) of sediments filling of this canalisation and of associated carbonated crusts show a succession of accumulation and erosive phases, driven by variations of the water level. Sequential stratigraphy allows the identification of gaps in the sedimentary sequence corresponding to cleanings and backfills of some sections of the canalisation. Combustion waste a…
