Supporting Information for the publication: The influence of slipface angle on dune growth

Dataset

Description

Dune characteristics as calculated with the bedform tracking tool. Data contains dune characteristics (dune height, length and slipface angles) during dune growth from an initial flatbed in a laboratory flume.

Explanation of variables in columns from left to right:
1: Time relative to dune equilibrium time ((T/Te) in (s/s))
2: Dune height relative to equilibrium dune heigth ((H/He) in (m/m))
3: Dune length relative to equilibrium dune length (L/Le in (m/m))
4: Dune steepness (height over length) ((H/L) in (m/m)).
5: Dune slipface angles (in degrees).

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.
