Background and side conditions
Environmental problems have influenced dredging methods in recent decades. Therefore, in 1980 Hamburg introduced a Dredged Material Research Program in order to investigate the contamination problems of the Elbe sediment and to develop technologies for treatment, beneficial use, and disposal of dredged material while, at the same time, taking care of the environment.
Relocation of sediments is restricted to material fulfilling the criteria according to the ARGE Elbe assessment scheme of 1996. Sediments with contamination level acceding these threshold levels are treated on land.
The measure indirectly contributes to the requirements of the WFD, because the contaminated sediments are removed from the river. Therefore it contributes to the improvement of the water quality of the Elbe estuary, as requested by the WFD. The removal of contaminated sediments is part of the ‘River engineering and sediment management concept’ which was developed in 2008 by Hamburg Port Authority and the Federal Administration for Waterways and Navigation (WSV), and approved by the Senate of the City of Hamburg.
