Sediment-Trap near Wedel


The sediment trap was implemented to meet different targets. First of all the residual transport of marine sediments from the North Sea towards the Port of Hamburg should be reduced in order to achieve a reduction of dredging amounts and costs in the Hamburg port area itself. Secondly the less contaminated North Sea sediments are trapped before they reach the port area and mix-up with higher polluted sediments in the harbor. Therefore the less contaminated sediments do not have to be treated on land and can be relocated further downstream where the ebb current dominates the flow regime. Thirdly the limited clearing of only the sediment trap also leads to economically optimized maintenance dredging activities.
