We conducted experiments to examine how steadiness-unsteadiness of source parameters is reflected in density currents in air. We ran experiments with other wise steady supply broken by two intervals (e.g. 30-10-30-10-30, or 30-5-30-5-30, where currents were supplied for 3 intervals of 30 s separated by 10 or 5 second pauses).

Experiments using simulated vegetation to understand how different vegetation densities (0-4% density by area) modify near-bed flow turbulence, flow structures and bedload transport. Data include spatial variation in bedload fluxes around vegetation and total bedload fluxes measured using high-speed video for 12 runs. Near-bed flow instantaneous velocities and velocity profiles (streamwise and vertical directions) were also measured in 3 streamwise transects using PIV.
