The present work deals with stockpiles, which have their profiles described by a sinus function or by similar trigonometric functions. Analysis of the erosion by air flow over these piles will provide for further understanding of the erosion underlying mechanisms and, moreover, how to control them and eventually to prevent them. To this purpose, different experimental tests are conducted for a pile with a sinuous profile, and particular attention is given to the time development of the profile due to the erosion process; the effect of the air velocity is also studied by selecting different velocities. In addition, the flow over several deformed piles is numerically predicted using the CFX software; the results clearly show the erosion process is strongly dependent upon time, velocity field and surface disturbances. A correlation between the erosion rate and the velocity is proposed.
