Gonzalez, Carlos A., Auteur ; Masayuki Takahashi, Auteur ; Chanson, Hubert, Auteur |On a spillway chute, a stepped design increases the rate of energy dissipation on the chute itself and reduces the size of a downstream energy dissipater. Up to date, the effects of step roughness on the flow properties remain unknown despite th[...]

Chanson, Hubert, Auteur |In dam break waves, the surge front is a sudden discontinuity characterized by extremely rapid variations of flow depth and velocity. In this study, simple analytical solutions for instantaneous dam break wave are developed using the method of c[...]

Chanson, Hubert, Auteur |Les buses de drainages, et canaux de drainage à ciel ouvert, font partie des ouvrages hydrauliques les plus courants. Au milieu du 20ème siècle, des ingénieurs australiens ont introduit un nouveau concept : le système de drainage à Pertes de Cha[...]

Chanson, Hubert, Auteur |A free-surface flow can change from a supercritical to subcritical flow with a strong dissipative phenomenon called a hydraulic jump. Herein the progress and development in turbulent hydraulic jumps are reviewed with a focus on hydraulic jumps o[...]

Chanson, Hubert, Auteur |Le nom de Jean-Baptiste BÉLANGER est souvent associé au ressaut hydraulique, et à l'application de l'équation de conservation de la quantité de mouvement. Une étude de son essai publié en 1828 montre que le thème principal était le calcul des éc[...]

Chanson, Hubert, Auteur |Tidal bores are a hydraulic phenomenon that is often not well explained and poorly documented. Herein, the writer explains what a tidal bore is, where it occurs, since when it has been observed, how it develops and why the occurrence of a bore h[...]

Chanson, Hubert, Auteur |Today the concept of "potential flow" is too often associated, wrongly, with the notion of ideal, hence inviscid fluid. Herein the original development of Joseph-Louis LAGRANGE is presented. He introduced the velocity potential for real fluid fl[...]

Chanson, Hubert, Auteur ; Gualtieri, Carlo, Auteur |A hydraulic jump is characterized by some strong turbulence and air entrainment in the roller. New measurements were performed in two channels in which similar experiments with identical inflow Froude numbers and relative channel widths were con[...]

Chanson, Hubert, Auteur |Dam break waves have been responsible for numerous losses and tragedies. The present work is focused on simple solutions of the dam break wave problem using the Saint-Venant equations Theoretical solutions are developed for instantaneous dam bre[...]

Le Tsunami du 26 Décembre 2004: un phénomène hydraulique d'ampleur internationale: premiers constats
Chanson, Hubert, Auteur |The 26 December 2004 tsunami was caused by a massive earthquake of magnitude 9.0 off western Sumatra. The tsunami waves propagated in the Indian Ocean with an amplitude of between 0.5 to 1 m. The tsunami waters surged on all coastlines of the In[...]

Gonzalez, C. A., Auteur ; Chanson, Hubert, Auteur |Current expertise in air-water turbulent flows on stepped chutes is limited mostly to laboratory experiments at low to moderate Reynolds numbers on chutes with flat horizontal steps. In this study, highly turbulent air-water flows skimming down [...]

Christian Koch, Auteur ; Chanson, Hubert, Auteur |A positive surge results from a sudden change in flow that increases the flow depth. New experiments were conducted in a large channel. Most positive surge tests were conducted with a horizontal bed slope, a constant flow rate and uncontrolled f[...]

Nazanin Khezri, Auteur ; Chanson, Hubert, Auteur |A tidal bore is a positive surge taking place during the flood tide with a large tidal range and the bore corresponds to the leading edge of the tidal wave propagating upstream. In this study, some physical modelling was performed to investigate[...]
