Bifurcation Analysis of the Transition of Dune Shapes under a Unidirectional Wind
Bifurcation Analysis of the Transition of Dune Shapes under a Unidirectional Wind
A bifurcation analysis of dune shape transition is made. By use of a reduced model of dune morphodynamics, dune skeleton model, we elucidate the transition mechanism between different shapes of dunes under unidirectional wind. It was found that the decrease in the total amount of sand in the system and/or …
