DeutschSand wave
A sand wave is a lower regime sedimentary structure that forms across from tidal currents.[1]
Formation
[edit]Sand waves are formed through the action of the wind or water (through waves or tidal currents)[2] and are a product of unidirectional flow. Sand waves are the result of a mean flow velocity between 40 and 70 cm/s.
Sand waves also form underwater.[3][4]
