These sedimentary reservoirs may represent a great environmental issue as they may constitute sinks for Metallic Elements (ME). Dam contexts allow studying the temporal evolution of contaminated sediments transfers (and ME) by different mechanisms (e.g., flood events), notably by resuspension and homogenization processes.• This study has been focussed on a watershed mainly affected by past mining activities (± 6 t of Ag and ± 6000 t of Pb were extracted until the 19th century), where sediments have been accumulated %G English %L hal-01879661 %U https://sde.hal.science/hal-01879661 %~ SHS %~ SDE %~ UNILIM %~ UNIV-SAVOIE %~ UGA %~ CNRS %~ OSUG %~ EDYTEM %~ AO-GEOGRAPHIE %~ GRESE %~ GIP-BE %~ GEIST %~ EDYTEM-GROUPE-ARCHIVES-ENVIRONNEMENTALES %~ EDYTEM-THEME-CHANGEMENTS-ENVIRONNEMENTAUX-SOCIETES %~ PEIRENE %~ TEST-HALCNRS %~ USMB-COMUE %~ OMEGAHEALTH %~ TEST3-HALCNRS %~ TEST4-HALCNRS %~ LABCIS %~ TEST5-HALCNRS
