Back to overview measures
The feasibility study showed the possibility of affecting the sedimentation patterns by regulating the discharge through the branches of the Norder- and ‘Süderelbe’. The benefits regarding the dredging needs were however rather low, because of the new (only shifted) sedimentation that occurs elsewhere in the port of Hamburg. An overall reduction of sedimentation within the port could not be achieved by regulating the freshwater current in the described way.
This study can be seen as a necessary step in enhancing the knowledge on the interrelation between sedimentation and headwater discharge. The idea will not be pursued furthermore.

Crux of the matter
The idea of regulating the sedimentation within the Port of Hamburg by the use of a well directed controlled headwater discharge through the two branches of the Elbe estuary had a lot of maintainers and opponents.The feasibility study showed the possibility of affecting the sedimentation patterns by regulating the discharge through the branches of the Norder- and ‘Süderelbe’.
