Wind ripples in an active drift sand area in the Netherlands: a preliminary report

Authors(s) and Affiliation(s)



Two types of wind ripples are distinguished in an active drift sand area near Hulshorst in the Veluwe (Central Netherlands). The common type has amplitudes of about 0,5 cm and wavelengths of about 11 cm, the atypical ripple has amplitudes of about 1 cm and wavelengths of some 16 cm. It is tentatively suggested that wind ripples are initiated by a regular downwind alternation in the impact energy of the descending grains in saltation, possibly due to fixed gravity waves in the sheared flows of air with grains which have strong density gradients with height.
