Sand waves are wavelike subaqueous sediment structures that exist in large areas in shelf seas. Due to their characteristics sand waves can severely affect human offshore activities, such as navigation. This makes it important to understand the physical processes that shape and change sand waves. In field data, temporal variation in the migration and the shape of sand waves are found. Besides other factors, surface wave action might cause this variation. In this study, a morphodynamic model and field data were used to investigate the importance of the surface waves on sand wave migration and shape. The field observations show that periods with surface waves can significantly affect the sand waves. Model results indicate that the surface waves explain these changes partly. Possibly surface waves in combination with a variation in the tidal current will explain the effects in a larger extent.
