Abstract
    Sedimentary structures and grainsizes on sandwaves in the Flemish Bank area are studied in relation to the morphology of the sandwaves. There is a difference between sandwaves in deeper water and sandwaves on top of a sand bank. The trough of the sandwaves in deeper water shows bioturbated structures, indicating a less dynamic environment than the top of the sandwaves, which is characterised by migrating megaripples. The sandwaves on top of the bank do not show bioturbation, but primary structures generated by migrating megaripples. In general the grainsize increases from the troughs towards the crests of the sandwaves.
