Numerische Simulation der Morphogenese von Windwatten.
Die Küste, 60
Modeling of morphodynamic processes requires
more diverse data sets than conventional hydrodynamic simulations: high-resolution
bathymetry, detailed information on sediment parameters, hydro-dynamic
and transport boundary conditions for scenarios under investigation.
Morphodynamic models are run for limited
domains in the coastal zone. Input data for these regional models are obtained
from large scale circulation models of the atmosphere and the Baltic Sea
provided by local agencies and coastal data centers.
Model validation relies on long-term water
level data from coastal gauges, wave data from near- and off-shore buoys
as well as wind measurements. Additional current meter data in channel
systems is used for the assessment of simulated 2D flow patterns.
Long-term simulation of wave-induced sediment
transport is checked against coastal profile data at selected locations
for various periods. First estimates of littoral transport are obtained
from 1D long-shore models applied in uniform parts of the coastline. This
information is used to specify reasonable boundary conditions for 2D area
Definition of scenarios for significant
morphodynamic activity is based on long-term analyses of wind, wave and
water-level field and hindcast data.
