3 Data base
The database for all investigations can be characterized using die data from die seabed
which is needed to describe physical sediment properties (e.g., grain size distribution, porosity,
...), bathymetry over several years and bed forms. Different datasets were therefore
compiled and assessed in AufMod:
1. sedimentological data,
2. bathymetry data,
3. hydrodynamic and meteorological data and
4. model results after model set-up, running and interpolation as well as interpretation.
3.1 Sediment data
The following parameters were relevant for morphodynamic modelling:
1. grain size analyses of surface sediments,
2. porosity,
3. thickness of the mobile sand layer and
4. content of organic matter in muddy sediments.
