Bedload transport though vegetation

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.
