|The first tidal calculation machine, built 1915/16 following specifications given by H. Rauschelbach in Potsdam. This fully-mechanised machine took into account 20 so-called partial tides and required only 10-15 hours to deliver the annual values of a harbour. Its construction is closely connected with the special requirements of marine navigation during the first world war.|
The history of the arduous beginnings of tidal research until the highly-technical research today is shown, as far as the German parts are concerned, in the recently opened exhibition areas of the German Maritime Museum.
