Supporting Information for the publication: The influence of slipface angle on dune growth
CC BY-SA 4.0
Data contains dune characteristics (dune height, length and slipface angles) during dune growth from an initial flatbed in a laboratory flume. Dune characteristics are derived using a widely used bedform tracking tool.
Explanation of variables:
1: Time relative to dune equilibrium time.
2: Dune height relative to equilibrium dune heigth.
3: Dune length relative to equilibrium dune length.
4: Dune steepness (height over length).
5: Dune slipface angles (in degrees).
Methods, materials and software:
Experiments were conducted in a tilting flume with recirculation facilities for both water and sediment in the Kraijenhoff van de Leur laboratory for Water and Sediment dynamics, Wageningen University & Research.
The flume measures 1.20 m x 0.50 m x 14.4 m internally (width x height x length). A 15 cm thick layer of uniformly distributed, light-weight polystyrene particles was installed at the flume bed with a density of p_s=1055 kg m^(-3).
Dune slipface angles are the steepest part of a dune leeside. Dune slipface angles are calculated with the bedform tracking tool using MATLAB.
