 Flooding causes extrême matter flows to the sea but also towards the soils in the alluvial plain. This study sets out the results obtained on the translocation of sédiments and associated contaminants onto the most flooded areas of the lower part of the Rhône valley during the extrême event of December 2003. We determined the quantifies and spreading of sedimentary deposits and associated stable and radioactive contaminants. Finally, the conséquences of such extrême flooding on the contamination of the food chain are estimated.
