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.
