An experimental study has been conducted at the CNRS Coriolis Rotating Platform at LEGI,
Grenoble, in a trapezoidal cross section channel, to investigate uni and bi-directional
exchange flows. Both rotating and non rotating experiments, with a non-erodible and
erodible bed layer were considered. Experimental measurements focused on obtaining high-
resolution velocity and density fields in different vertical planes spanning the width of the
channel using 2D Particle Image Velocimetry, Laser Induced Fluorescence, ADV and micro …

Laboratory experiments on uni and bi-directional exchange flows have been conducted at
the CNRS Coriolis Rotating Platform at LEGI. Both rotating and non-rotating experiments
were performed in a trapezoidal cross section channel and different configurations were
considered by varying both the upper fresh water volume fluxes and the channel rotation
rates. Detailed 2D velocity fields were measured by Particle Image Velocimetry in different
vertical planes spanning the width of the channel. Results show that as the rotation rate …
