## Abstract This paper focuses on a key problem in windโblown sand transport research, the liftโoff velocities of sand grains. A threeโdimensional grainโbed collision model comprising an impact sand grain, a creeping sand grain and a sustaining grain is presented. Based on this model, the analytica
