Draix-Bleone critical zone observatory

Abstract

International audienceDraix-Bleone observatory is located in the French South Alps in a highly erodible badland area. It was created in 1983 to study hydrology and erosion processes in mountain and its focus has been extended since then to critical zone processes, including interactions between physical, chemical and biological components. In this poster we present recent results and innovative methods ranging from detailed measurements and modeling of sediment transport and soil moisture, chemical and physical denudation rates, chemical tracing of water fluxes, to the interactions between plant traits anddiversity, soil formation and stability, and interactions between vegetation cover and erosion
