Digital Library of Periodicals of National Academy of Sciences of Ukraine| Zusammenfassung: | An adjoint based technique is applied to a Shallow Water Model in order to estimate
influence of the model’s parameters on the solution. Among parameters the bottom topography,
initial conditions, boundary conditions on rigid boundaries, viscosity coefficients
and the amplitude of the wind stress tension are considered. Their influence is analyzed
from different points of view.
Two configurations have been analyzed: an academic case of the model in a square
box and a more realistic case simulating Black Sea currents. It is shown in both experiments
that the boundary conditions near a rigid boundary influence the most the solution.
This fact points out the necessity to identify optimal boundary approximation during a
model development. |
