Sand Dunes Of Khenifiss National Park Of Morocco

Drifted by winds, the dunes move and change their shape. We can observe the evolution of them in the time series of satellite images, such as those provided by Google Earth. Here we consider the dune field of the Khenifiss National Park of Morocco. We see that these dunes, which spent several years having, more or less, the same shape, are now remarkably changing, as evidenced by the recent satellite images of 2016. The origin of this strong deformation is in the change of the wind direction.
