Abstract
Equilibrium sand transport is simulated by stochastic Lagrange particle tracking method combined with probability distribution of initial ejection state of sand grains. Comparing the simulated vertical profile of horizontal sand mass flux and the experimental profiles, a modified exponential distribution is suggested to describe ejection speed and angle of sand grains in equilibrium sand transport. This modified exponential distribution is proved to be reasonable in slow wind velocity.
