Dunes

Dunes are mounds or ridges of wind-blown sand that form in arid regions and along coasts, areas where there is plenty of sand, strong winds, low rainfall, and some vegetation or obstructions to trap the sand. The shape of a dune—crescent, linear, star, dome, or parabolic, to name a few—is dictated by the prevailing wind pattern. Dunes that are not stabilized by vegetation often migrate, driven by the wind, and may cause damage as they move. What are some techniques for halting their migration?
