Resumo: | While dominant processes and time-scales controlling denudation rates are intensively debated, past terrigenous input remains difficult to detect from the marine sedimentary record, especially during the Quaternary because of the strong overprint exerted by the sea-level changes. In this study, we focus on the Var sediment-routing system (SE France) where the absence of a continental shelf off the Var river mouth (Ligurian margin, NW Mediterranean Sea) resulted in the direct connection between the Var River and the deep basin during both highstand and lowstand conditions. Moreover hyperpycnal flow initiated during Var floods are the main sediment transfer processes in the Var turbidite system, making changes in sediment supply within headwater source regions possible to discern in the stratigraphic record of the distal sedimentary basin...
