IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Mixing downstream a 90กใ open channel junction

ABSTRACT
The work deals with the mixing of scalars within open-channel confluences. Experiments are performed in a 90กใ
confluence of equally wide, rectangular, horizontal channels with a high branch to upstream momentum ratio. A new
method, based on pH measurement, provides 3D concentration fields throughout the flow and permits to work in closedloop
without wasting water. The measurements exhibit a rapid mixing, enhanced by the presence of large-scale
secondary currents. Operational numerical computations appear to be in fair agreement with the measurements and
permit to gain information on the complex measured and computed 3D concentration field processes.
