Back to overview measures
Anthropogenic and natural changes along the estuary resulted in a strong upstream sediment transport which finally led to high sedimentation rates in the area of Hamburg. The amount of dredged material increased during the last years.
Adjustments of the inner areas of Hamburg harbor resulted in changes in current velocities and influenced sedimentation and erosion processes in harbor basins. At conditions of low freshwater discharge a silting up tendency is observed in the ’Süderelbe‘ which is the area where the container terminal ‘Altenwerder’ and the bifurcation channel ‘Köhlbrand’ are located.
The intention of the measure was to control the amount of freshwater at Bunthaus that runs either in the ‘Norderelbe’ or in the ‘Süderelbe’ by installing a movable construction. The used river engeneering model was commisioned by Hamburg Port Authority (HPA) and the Administration of Waterways and Navigation (WSA Nord). The company DHI WASY GmbH set up the model and carried out the calculations.
