Abstract
Simple models for the formation dynamics of two scales of sand features are proposed. In the simulation of the small scale model, a ripple pattern is spontaneously formed by the saltation of sand grains when the wind force exceeds a critical value. With the large scale model, the dynamics of sand dunes is discussed.
