Functions

Bed_Instability_Orientation	Calculate the dune orientation growing from the flat bed instability as the maximum of the dimensional growth rate calculated in Courrech du Pont at al.
Elongation_direction	Calculate the elongation direction as the dune orientation for wich the components of the resultant sand flux at the dune crest perpendicular to the dune crest cancel each other out.
Flux_at_crest	Calculation of the sand flux at the dune crest:
Growth_rate	Calculate the dune growth rate using the dimensional analysis from Courrech du Pont et al. 2014.
Resultant_flux_at_crest	Resultant flux (i.e vectorial average) of the sand flux at the crest.
Resultant_flux_perp_crest_at_crest	Component of the resultant flux (i.e vectorial average) at the crest perpendicular to the dune crest.
