• The physics of wind-blown sand and dust (2012, background): “As is evident from equations (2.10) and (2.14), the steady state impact speed at which the replacement capacity equals unity is not dependent on u∗ (Ungar and Haff 1987, Andreotti 2004, Kok 2010a, Durán et al 2011a).”
• A comprehensive numerical model of steady state saltation (COMSALT) (2009, background): “Since the average impact speed is independent of shear velocity [Ungar and Haff, 1987; Andreotti, 2004], as also found by our model simulations (Kok, manuscript in preparation, 2009), we expect particle speeds for different shear velocities to converge near the surface.”

• Saltating particles in a turbulent boundary layer: experiment and theory (2009, methodology): “Numerical simulations have also been undertaken (Ungar & Haff 1987; Anderson & Haff 1988, 1991; Werner 1990) and analytical models proposed (Owen 1964; Sørensen 1991, 2004; Sauermann, Kroy & Herrmann 2001; Andreotti 2004; Duran & Herrmann 2006) to explain the empirical findings. The numerical simula”
• Measurements of the aeolian sand transport saturation length (2008, background): “As shown by Ungar and Haff 1987 and Andreotti 2004, the saturated flux qsat is proportional to (U2 −U2th)H(U −Uth), where Uth is the threshold value for transport, and where H(x) is the so-called Heaviside function [H(x > 0) = 1 and H(x 0) = 0].”
• On aeolian transport: Grain-scale interactions, dynamical mechanisms and scaling laws (2011, methodology): “A tentative explanation for the origin of this scaling can be found in the different behavior of saltating grains, which follow the wind, and grains in reptation, which are more sensitive to the bed slope (Howard, 1977; Andreotti, 2004; Hersen et al., 2004).”
