Reduction of bend scour with an air-bubble screen - morphology and flow patterns

Anton Schleiss, Koen Blanckaert, Violaine Dugué

The interplay between streamwise flow, curvature-induced secondary flow, sediment transport and bed morphology leads to the formation of a typical bar-pool bed morphology in open-channel bends. The associated scour at the outer bank and deposition at the i ...

Influencing Flow Patterns and Bed Morphology in Open Channels and Rivers by Means of an Air-Bubble Screen

Anton Schleiss, Koen Blanckaert, Violaine Dugué

The ability of a bubble screen to redistribute the flow field and bed morphology in shallow rivers and open channels has been investigated in laboratory experiments. Rising air bubbles generated by a pressurized porous tube situated on the bed induced seco ...

A method for assessing the feasibility of air-bubble screens to reduce morphological gradients in open-channel bends

Anton Schleiss, Koen Blanckaert, Violaine Dugué

Within the fluvial network, confluences are particular areas characterized by great ecological value where flow dynamics and bed morphology are much influenced by local patterns. The aim of this article is to describe the influence of the convergence angle ...

Etude sur modèle physique du nouvel évacuateur de crue du barrage de Gage II

Michael Pfister, Fadi Hachem, Violaine Dugué

Suite à des études hydrologies récentes, le barrage de Gage II en France révèle un déficit de capacité d'évacuation des crues. Il a donc été décidé de construire un évacuateur de creue complémentaire en rive droit du barrage. Cet ouvrage est composé d'un P ...
