The study ‘Managing Reiherstieg sluice’ is not assigned to the WFD nevertheless it covers one of the main pressures of the freshwater zone of the Elbe estuary. The study that was carried out shows the possibility of influencing the oxygen content in some parts of the port. Before implementation some unclear questions concerning flow velocities, navigation factors and sediment re-mobilization has to be pre checked and cleared up.
