Flow-dynamic parameters captured by the velocity probes. a Time-averaged velocity profiles for the turbidity current in the experiment with loss of confinement. b Time-averaged velocity profiles for the turbidity current in the reference experiment (see Figs. 2 and 3 for probe locations). c Depth-averaged velocity. The turbidity current downstream of the loss of confinement was slower than the turbidity current in the reference experiment. d Flow thickness. After leaving the confinement the calculated turbidity current thickness decreased. e Shear velocity. Shear velocity downstream of the loss of confinement was increased in comparison with the reference experiment. See Methods for details on average calculations
