Kurzbeschreibung (Abstract)
We study how a coastal obstruction (peninsula or coastal island) affects the three-dimensional barotropic currents in an oblong rectangular basin with variable bathymetry across the basin width. The transverse depth profiele is asymmetric and the peninsula or island lies in the middle of the long side of the rectangle. A semi-spectral model for the Boussinesq-approximated shallow water equations, developed in Haidvogel et al. and altered for semi-implicit numerical integration in time in Wang and Hutter, is used to find the steady barotropic state circulation pattern to external winds. The structural (qualitative) rearrangements and quantitative features of the current pattern are studied under four principal wind is inclination relative to the shore. The essentially non-linear relationships of the water flux between the two sub-basins (formed by the obstructing penisula) and the corresponding crosssectional area left open are found and analysed. It is further analysed whather the depth- integrated model, usually adopted by others, is meaningful when applied to the water exchange problems. The flow through the challel narrowing is quantitatively estimmated and compared with the three- dimensional results. The dynamics of the vortex structure and the indentification of the up-welling/down-welling zones around the obsrruction are discussed in detail. The influence of the transformation of the penisula into a coastal islang on the gloabal basin circulation is considered as are the currents in the channel. The geometric and physical reasons for the anisotropy of the current structure which prevail through all obtained solutions are also discussed.
