Two-Species Continuum Model for Aeolian Sand Ripples
Hoyle, Rebecca B. and Mehta, Anita (1999) Two-Species Continuum Model for Aeolian Sand Ripples Physical Review Letters, 83 (24). pp. 5170-5173.
We formulate a continuum model for aeolian sand 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. We predict analytically the ripple wavelength, initial ripple growth rate, and threshold saltation flux for ripple formation. Numerical simulations show the evolution of realistic ripple profiles from initial surface roughness via ripple growth and merger.
