Figure 17: Characteristic sediment transport pathways in the mouth of the Elbe estuary for the 
year 2000 and 2010. 
6.2 Sediment balance 
The net sediment transport quantity entering and leaving the German Bight was estimat 
ed by defining analysis profiles to integrate the sediment mass over one year as a balance. 
Fig. 18 shows these results for three different model investigations: Un-TRIM (red: 
1996-2007), TELEMAC (green: 1998 and 2006) and MARINA (light blue: 2006). Com 
pared with die duration [d] of high wind (> 18 m/s) at Elelgoland, tiiere is a remarkably 
clear correlation between transport and wind. 
The export of sediment mass from die German Bight is one order of magnitude 
smaller than the input. No results for die exchange widi the estuaries are available due to 
the relatively coarse spatial grid resolution of the numeric models. These exchange quan 
tities are consequently not well incorporated to die mass balance.
