Stability of transverse dunes against perturbations; a theoretical study using dune skeleton model
H. Niiya, A. Awazu, H. Nishimori
The dune skeleton model is a reduced model to describe the formation process and dynamics of characteristic types of dunes emerging under unidirectional steady wind. Using this mod…
Bifurcation analysis of the transition of dune shape under unidirectional wind
Hirofumi Niiya, Akinori Awazu, Hiraku Nishimori
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 differ…
3D Dune Skeleton Model as a Coupled Dynamical System of 2D Cross-Sections
Hirofumi Niiya, Akinori Awazu, Hiraku Nishimori
To analyze theoretically the stability of the shape and the migration process of transverse dunes and barchans, we propose a {\it skeleton model} of 3D dunes described with coupled…
