Three-Dimensional Dune Skeleton Model as a Coupled Dynamical System of Two-Dimensional Cross Sections
Three-Dimensional Dune Skeleton Model as a Coupled Dynamical System of Two-Dimensional Cross Sections
To theoretically analyze the stability of the shape and the migration process of transverse dunes and barchans, we propose a skeleton model of three-dimensional (3D) dunes described by the coupled dynamics of 2D cross sections. First, the 2D cross sections of a 3D dune parallel to the wind direction are …
