Continuum models for aeolian sand ripples

Abstract: Aeolian sand ripples are formed by the action of the wind on the sand bed in the desert and at the seashore. They have also recently been observed on Mars. I will discuss continuum models that describe the evolution of ripples consisting of two species of grains: a lower layer of relatively immobile clusters, with an upper layer of highly mobile grains moving on top.
