The apparent roughness of a sand surface blown by wind from an analytical model of saltation
Thomas Pähtz, Jasper F. Kok, Hans J. Herrmann
We present an analytical model of aeolian sand transport. The model quantifies the momentum transfer from the wind to the transported sand by providing expressions for the thicknes…
Jump at the onset of saltation
M. V. Carneiro, T. Pähtz, H. J. Herrmann
We reveal a discontinuous transition in the saturated flux for aeolian saltation by simulating explicitly particle motion in turbulent flow. The discontinuity is followed by a coex…
A Model of Barchan Dunes Including Lateral Shear Stress
V. Schwaemmle, H. Herrmann
Barchan dunes are found where sand availability is low and wind direction quite constant. The two dimensional shear stress of the wind field and the sand movement by saltation and…
A Continuum Saltation Model for Sand Dunes
G. Sauermann, K. Kroy, H. J. Herrmann
We derive a phenomenological continuum saltation model for aeolian sand transport that can serve as an efficient tool for geomorphological applications. The coupled differential eq…
