The Density Current Flume has been used primarily in research of density driven flows. The flume measures 14.5-m long, 1.2-m deep, and 0.45-m wide. An 830 liter head tank is located at the upstream end of the flume; a stainless steel sluice gate separates the head tank from the rest of the flume and can be used to confine the initial height of a density flow during an experiment. A 17,400 liter receiving tank is located at the downstream end of the flume and is used to collect sediment during experiments.
In its current configuration, the flume has a false bottom installed at a 5% slope – this slope can be varied from 0% to approximately 8%.
Past research in this facility includes experiments on self-accelerating turbidity currents1, deep sea sedimentary deposits2, 3, and saline underflows over movable beds4.
