| Zusammenfassung |
| In this work we present a study of the circulation driven by the freshwater and by the wind in
the Romanian coast. To carry out this study a finite element model of the whole Black Sea
has been used to obtain a high resolution mesh near the coast and the Danube inlets able to
resolve the sub-mesoscale features. The computational domain covers the whole Black Sea,
to avoid problems in specification of the open boundary conditions. Several theoretical
simulations were carried out in order to understand the influence of the Danube discharge,
wind and salinity on the coastal current. The obtained results show that the discharge from
the Danube strongly influences the currents along the entire Romanian Black Sea
coast. The simulations results show the formation of an along shore current mainly
in the surface layers, which is in agreement with previous studies on the Black
Sea.
The strength of the coastal current depends on the Danube discharge. However, even at a
low discharge, there is still the formation of a coastal current, due to the changes in salinity
induced by the freshwater from the Danube River.
The wind has a different effect depending on the direction. Wind from northeast keeps the
freshwater near the coast while wind from southern directions pushes it offshore and rapidly
mixes it with the more salty water. |
