Nonlinear Dynamics of Aeolian Sand Ripples
arXiv:cond-mat/9807006 · doi:10.1103/PhysRevE.60.729
Abstract
We study the initial instability of flat sand surface and further nonlinear dynamics of wind ripples. The proposed continuous model of ripple formation allowed us to simulate the development of a typical asymmetric ripple shape and the evolution of sand ripple pattern. We suggest that this evolution occurs via ripple merger preceded by several soliton-like interaction of ripples.
