mesure de débit en rivière par station radar hauteur / vitesse selon la méthode de la vitesse témoinThollet, F. / Le Coz, J. / Dramais, G. / Nord, G. / Le Boursicaud, R. / Jacob, E. / Buffet, A. / Pierrefeu, G. - 2017In recent years, stage / velocity radar stations have been installed in France. This type of stations provides measurements of water level and surface velocity at a fixed point of the cross-section. Discharge is calculated as the product of the wetted area and cross-sectional average velocity;...Contributeur (s):

Mansanarez, V. / Le Coz, J. / Renard, B. / Lang, M. / Pierrefeu, G. / Le Boursicaud, R. / Pobanz, K. - 2017Stage-fall-discharge (SFD) rating curves are traditionally used to compute streamflow records at sites where the energy slope of the flow is variable due to variable backwater effects. Building on existing Bayesian approaches, we introduce an original hydraulics-based method for developing SFD...Contributeur (s):

Le Coz, J. / Renard, B. / Bonnifait, L. / Branger, F. / Le Boursicaud, R. - 2015Discharge time series in rivers and streams are usually based on simple stage-discharge relations calibrated using a set of direct stage-discharge measurements called gaugings. Bayesian inference recently emerged as a most promising framework to build such hydrometric rating curves accurately and...Contributeur (s):
