Description:
Dune slipface angles as calculated with the bedform tracking tool. Data contains dune slipface angles for different experimental conditions as shown in figure 4 of the submitted manuscript.


This dataset contains the following file:
Dune_Slipface.csv


Explanation of variables:
EXP3: Dune slipface angles (in degrees) for Bedload dominated flow conditions.
EXP4: Dune slipface angles (in degrees) for Mixedload dominated flow conditions.
EXP8: Dune slipface angles (in degrees) for Mixedload dominated flow conditions.
EXP9: Dune slipface angles (in degrees) for Suspendedload dominated flow conditions.


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.
