The ’’Fryberger Method’’ provides a useful and accessible way of evaluating potential sediment transport by wind. In this method an equation is used to estimate relative rates of sand transport (expressed as drift potential) from measurements of wind velocity. However, the values of drift potential obtained through the calculations are dependent upon the units in which wind velocities are expressed. This paper highlights some of the confusion this dependence can cause and aims to clarify the ways in which values of drift potential can be interpreted.
