Incision rate changes in the upper Var River catchment, southern French Alps: from observations to models. Conference Paper uri icon

abstract

  • Abstract Cosmic Ray Exposure (CRE) dating on river polished surfaces from gorges located in the Var River catchment (Southern French Alps) reveals high incision rate pulses (> 10 mm. yr-1) related with climate changes, and in particular with glacial-interglacial transitions. In addition, they show that the onset of the last deglaciation in this area occurred shortly after the Last Glacial Maximum (LGM), ie 16-19 ka ago. Extrapolating these results to longer time scales suggests that the post 140 ka history of this landscape was dominated by fluvial …
