| Zusammenfassung |
| In order to easily enforce solid-wall boundary conditions in
the presence of complex coastlines, we propose a new mass and energy
conserving Brinkman penalization for the rotating shallow water equations.
This penalization does not lead to higher wave speeds in the solid region.
The error estimates for the penalization are derived analytically and
verified numerically for linearized one-dimensional equations. The
penalization is implemented in a conservative dynamically adaptive wavelet
method for the rotating shallow water equations on the sphere with bathymetry
and coastline data from NOAA's ETOPO1 database. This code could form the
dynamical core for a future global ocean model. The potential of the
dynamically adaptive ocean model is illustrated by using it to simulate the
2004 Indonesian tsunami and wind-driven gyres. |
