Fig. 6.1.4: Temporal evolution of water levels at Wick in two models (North Sea model 
10 km (green), North Sea model 2 km (red) with equal input signal (3 positive 
single signals, period 1800 s, wave height 5 m). 
Fig. 6.1.5\ Temporal evolution of water levels at Cuxhaven in two models (North Sea model 
10 km (green), North Sea model 2 km (red) with equal input signal (3 positive single 
signals, period 1800 s, wave height 5 m). 
Up to now, it has not been taken into account that a tsunami entering the North Sea does not 
encounter calm water but currents and water levels that have been influenced by tides and 
winds. The periods of the main components of tides and tsunami are relatively far apart, so
