Camenen, B. / Perret, E. / Herrero, A. / Berni, C. / Thollet, F. / Buffet, A. / Dramais, G. / Le Bescond C. / Lagouy M. - 2016Estimating the fine sediment budget in alpine rivers is an important challenge to better understand the morphodynamics of such rivers. This paper presents some first in-situ experiments describing the evolution of a fine sediment deposit over a gravel bar during a flushing event. Some modelling and...Contributeur (s):

Dramais, G. / Buffet, A. / Le Coz, J. / Branger, F. / Renard, B. / Horner, I. / Gallavardin, A. - 2017By combining noncontact streamgauging methods (LSPIV, radar) and the BaRatin method, we were able to build quickly a rating curve on a large flow range for an intermittent stream. / En combinant des jaugeages sans contact (LSPIV, radar) et la méthode BaRatin nous avons pu construire rapidement une...Contributeur (s):

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):

Pour répondre à cet objectif, un réseau de mesure en continu des concentrations en MES et de prélèvements de MES a été mis en place. Ce document décrit...Contributeur (s):

Perret, E. / Berni, C. / Herrero, A. / Camenen B. / El kadi Abderrezzak, K. / Buffet, A. - 2017A very large scatter has been observed for the incipient motion threshold of a gravel bed in lit-erature, which can be explained by a lack of bed surface characterization. In the present work, a laser scan-ning technique is used and criteria to describe the bed surface are proposed in order to...Contributeur (s):
