used for morphodynamic analyses. 
3.3 Hydrodynamic and meteorological data 
Meteorology and hydrodynamics are die driving forces of the morphodynamic in the 
German Bight. Hydrodynamic and morphodynamic models as well as morphodynamic 
analysis require information about the time varying water levels along die open (seaward) 
boundary, river discharge quantities and wind velocities in time and space in addition to 
bathymetry and sediment data:. 
• Water levels: The tidal signal was derived from die global tide model FES2004. 
• Run off from measurements in the German Bight and long-time means for the oth 
er river discharges from analysis. 
• Wind fields are taken from forecast weatiier model runs by die German Weather 
Forecast Service (DWD).
