Webb20 aug. 2024 · Ferreira and Fino ( 2012) proposed to study, through wind tunnel experiments, the erosion that occurs when two stockpiles are placed in tandem. The piles had 60 mm high (H) and two lengths were tested, L = 5H and L = 6H. Two upstream velocities, 8.3 and 9.1 m/s, and two distances between the piles, D = 0 and D=H, were … WebbBoth are created by wind erosion. Death Valley is a great place for sand dunes to be created. With a range on both sides and one to the north, the wind carries fine material to the north border of the valley. Here when the sand can no longer be carried, the wind deposits the sand in front of the barrier.
