Three different sets of experimental turbidity currents were run in which velocity and concentration were measured
simultaneously, for several different heights above the bed. One set with cohesive sediment had an initial volumetric
concentration of 16% kaolinite, and the other two sets with non-cohesive sediment had concentrations of 28% and 4% silica
flour. Velocity was measured at 104–122 Hz using an Ultrasonic Doppler Velocimetry Profiler and concentration was measured
at 10 Hz using an Ultrasonic High Concentration Meter.
