Description :
Wind tunnel experiments were conducted with a well mixed, flat sand bed, 5.7 m in length, to study the initial sand flux response at 3 different shear velocities. In some experiments, the bed was allowed to deplete without replenishment; in others, sand was fed 10.8 m upstream of the monitored cross-section. Many factors bring about non-stationarity in total sand transport rate. The nature and relative importance of each is discussed by reference to the reported wind tunnel experiments and to the behaviour of saltation cloud numerical models.
