Abstract

The paper describes a series of experiments in which dyed sand grains, spread on the surface of quartz dune sand in a wind-tunnel, were photographed at five second intervals while the sand was exposed to wind. The data on rate of loss of coloured grains was used, for two of three chosen size fractions, to deduce the dislodgment rate for each size fraction. The variation of this dislodgment rate with shear velocity is shown graphically for values of UX between 24 cm/s and 50 cm/s. Because of the artificial method of distribution of the coloured sand grains, the results should be applied with caution to natural conditions
