Sand wave explained

A sand wave is a lower regime sedimentary structure that forms across from tidal currents.^[1]

Formation

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]}
