Current velocity data from moored ADCPs (in the Hörnum Deep south of Sylt Island, 2002-2009) and ship cruises (in several locations in the German Wadden Sea, 2000-2008) were analyzed. As a general result, the vertical current profiles above the benthic boundary layer are usually more homogeneous during flood than during ebb, with a pronounced dependence on the cross-shore horizontal density difference. This tidal asymmetry consequently must lead to a residual outflow of Wadden Sea waters in the upper part and a residual inflow of water in the lower part of the water column, thus giving a generic explanation for the obvious net import of suspended sediments from the German Bight into the Wadden Sea.
