Abstract
Abstract. Draix-Bléone critical zone observatory was created in
1983 to study erosion processes in a mountainous badland region of the
French Southern Alps. Six catchments of varying size (0.001 to 22 km2)
and vegetation cover are equipped to measure water and sediment fluxes, both
as bedload and suspended load. This paper presents the core dataset of the
observatory, including rainfall and meteorology, high-frequency discharge
and suspended-sediment concentration, and event-scale bedload volumes. The
longest records span almost 40 years. Measurement and data-processing
methods are presented, as well as data quality assessment procedures and
examples of results. All the data presented in this paper are available on
the open repository https://doi.org/10.17180/obs.draix (Draix-Bleone
Observatory, 2015), and a 5-year snapshot is available for review at
https://doi.org/10.57745/BEYQFQ (Klotz et al., 2023).
