Datations au 137Cs, 134Cs et 210PB de dépôts de crues du XXe siècle

Abstract : This study was undertaken to test the application of environmental radioactive tracers to verify that the general trend for sediment accumulation in floodplain, often initiated during antique time, is still processing. Three sediment cores have been studied, collected on the floodplains of Rhône river tributaries : the Gardon d'Anduze river and Ouvèze river. We present the different tracers available in this environment. Artificial radioisotopes 137Cs and 134Cs make it possible to identify the extent of the last major floods. The natural radioisotope 210Pb confirms these observations but does not enable to date the previous ones.
