In this paper, the main morphometric and dynamic properties of aeolian ripples formed in a wind tunnel during the deposition of natural, silt-sized dust particles over a flat horizontal surface are investigated. Ripples and ripple patterns are studied after 15, 30, 45, 60, 75 and 90 minutes of dust deposition, and this for 4 free stream wind velocities ranging from 113 cm.s-1 to 160 cm.s-1 (friction velocity: 3.0 to 3.9 cm.s-1). All velocities are well below deflation threshold. The following ripple parameters are investigated: general ripple shape, ripple spacing, ripple height, ripple flattening, ripple length, ripple symmetry, ripple singularities, ripple orientation, ripple sinuosity and ripple migration. Mean values for the ripple fields as well as dispersion within the ripple fields are examined, and correlations with mean wind speed are made. All parameters are also investigated at different stages of ripple development.
