摘要：

While shoreface-connected sand ridges may be molded by storm-generated waves and currents, calm-weather counterparts may determine their longevity in the German Bight. Fair-weather flow measurements on shoreface ridges off Spiekeroog Island show that: (1) peak velocities (U-100 max) mostly range from 30 to 60 cm s(-1) and are flood asymmetric, except at neap tide when ebb flows are dominant in ridge troughs; (2) velocity contrast between accelerating and decelerating flow phases is higher for ebb than flood currents, suggesting intense interaction between inlet and shoreface ebb currents; and (3) tidal currents play a primary role in ridge maintenance.
