The σF/σI-values for transitions in dune shape as a function of the transport ratio N.
For a given N-value and an increasing θ-value, dune morphology changes from barchans to finger dune (black symbols) and from finger dune to asymmetric barchans (red symbols). For a given N-value, error bars give the range of σF/σI-values over which the transition is observed.
