Sand waves form a prominent regular pattern in the offshore seabed of sandy shallow seas such as the North Sea. They can be found at water depths of 10 to 50 m. Their wavelengths can lead up to 500 m and their heights are typically several metres. The positions of sand wave crests and troughs slowly change in time. Sand waves are assumed to migrate in the direction of the asymmetry in the water motion, with typical velocities of up to several metres per year.
