Performance of models to determine flow rate using orifice plates [PDF]

open access: yesRevista Brasileira de Engenharia Agrícola e Ambiental, 2020
This study aimed to evaluate three methodologies for orifice-plate water-flow estimation by quantifying errors in the flow determinations to propose an appropriate measurement range for each evaluated condition.

Crue du 23 novembre 2019 sur la Côte d’Azur : comparaison de débits estimés par analyse d’images et par modélisation hydrologique

open access: yesLHB Hydroscience Journal, 2022
Les précipitations courtes et violentes observées sur la Côte d’Azur conduisent souvent à des crues-éclairs sur les bassins versants côtiers : lors de la crue du 2 octobre 2015, un débit de pointe compris entre 185 et 295 m3/s a été estimé sur la Brague ...

Establishing and Operating (Pilot Phase) a Telemetric Streamflow Monitoring Network in Greece

open access: yesHydrology, 2023
This paper describes HYDRONET, a telemetry-based prototype of a streamflow monitoring network in the Greek territory, where such data are sparse. HYDRONET provides free and near-real-time online access to data. Instead of commercially available stations,

Validation of an Uncertainty Propagation Method for Moving‐Boat Acoustic Doppler Current Profiler Discharge Measurements

open access: yesWater Resources Research, 2023
The moving‐boat Acoustic Doppler Current Profiler (ADCP) gauging method is extensively used to measure the discharge of rivers and canals. Informed decisions related to water management require reliable estimates of the uncertainty of such measurements ...
