UNO experimental dataset for: Multiscale bedform reorganization at the onset of substantial suspended sediment transport

We collected data from three experiments that tracked bedform evolution in
a 22-m-long, 0.56-m-wide, and 0.9-m-deep flume at the University of New
Orleans' Dynamics of Sedimentation laboratory. Each experiment was
run at equilibrium conditions under steady, uniform, normal flow in a
fully closed system recirculating flume. All three experiments were run at
20cm mean flow depth, the same bed material sediment, but with varied
discharge: 20cm 30Hz experiment at 45 L/s, 20cm 35Hz experiment
at 51 L/s, 20cm 40Hz experiment at 56 L/s. We measured
topography using a 3D laser scanning system along an approximately
5.5-m-long test section, with scans repeated approximately every 165
seconds. We analyzed bed topography for the 2D centerline profile at 1 mm
horizontal resolution.
