A dune is usually defined as an accumulation of loose particles, deposited or reworked by the wind, with diameters varying from two or three milimeters to tens of micrometers. In fluvial environments (in seas, lakes or river streams) one can also find accumulations of loose particles deposited or reworked by the water, which are analogous to aeolian edifices. However, such banks of clay, sand ridges, and under water ripple marks, up to 30 m in height, cannot be considered as dunes because of the lack of sharp crests.
