Recent Developments in Hamburg's Coastal Protection

摘要

In 2012 Hamburg's government decided to raise the design water levels of the tidal River Elbe in the Hamburg region by about 0.80 m. As a consequence, the primary flood defences in the city have to be reinforced and heightened during the next 25-30 years. Prior to implementing the strengthening program for the dikes and sea walls, extensive design work has to be carried out, including wave simulations and the determination of freeboard heights, resulting in new crest levels for the various coastal flood protection facilities in the city.
