Streamflow monitoring at high temporal resolution based on non-contact instruments in the Galabre river (Southern pre-Alps, France)

Résumé

We provide a dataset for calculating streamflow in a river of the Southern pre-Alps in France over the period October 2018 to May 2021. The river is called the Galabre and is a tributary of the Bès, which in turn is a tributary of the Bléone. The hydrometric station, so-called RIPLE, which incorporates non-contact instruments, was described in detail by Nord et al (2020). It was installed at a site subject to frequent bathymetric changes, 2.5 km downstream of a historic hydrometric station called « La Robine », at the "Galabre" site of the Draix-Bléone observatory (https://draixbleone.osug.fr/). The dataset combines high-frequency monitoring (every 10 minutes) of water level and surface water velocity using radar, ground-based bathymetric surveys, video sequences recorded by fixed camera with velocity fields obtained using the Fudaa-LSPIV software (https://forge.irstea.fr/projects/fudaa-lspiv), and the results of theoretical models of velocity field distribution in the river section.
