RÉSUMÉLa quantification des incertitudes des données hydrométriques (mesure de débit des cours d’eau) est reconnue comme indispensable mais sa mise en œuvre pratique nécessite un ensemble d’outils adaptés au traitement des mesures sur l

Selon les résultats d’une enquête menée en 2017 auprès des gestionnaires de réseaux hydrométriques français, 1 % de leur activité de jaugeage est effectuée par la méthode de dilution. On constate ainsi une forte érosion dans la mise en

The operator effect is a prominent error source in image-based velocimetry methods. The LSPIV method is known to be sensitive to the parameters and choices of the user, as shown in the literature and emphasized by the results of a video gauging inter

The moving-boat Acoustic Doppler Current Profiler (ADCP) gauging method has been extensively used to measure the discharge of rivers and canals. To assess the quality of the data produced for all gauging situations, it is necessary to conduct an unce

EDF is the largest producer of hydroelectricity in Europe and France, with about 640 dams and an installed capacity of about 20GW. Sedimentation in dam reservoirs is a paramount issue for EDF, including impacts on electricity generation, on dam stabi

The operator effect is a prominent error source in image-based velocimetry methods. Video sampling, ortho-rectification parameters, motion analysis parameters and filters can strongly impact velocity and discharge measurements. This has been reported

We present the development of the River Platform for Monitoring Erosion (RIPLE) designed for monitoring at high temporal frequency (∼10 min) of water discharge, solid fluxes (bedload and suspended load) and properties of fine particles (settling
