spreads along isobaths (fig.2). As a result of that process
the value of density boundary lifting is much less then
the thickness of incoming bottom water layer. After
inflow the saline bottom water moves along right sea
slope (fig.3). While the bottom water spreads into the
Bornholm Basin its width grouse. In ten days after inflow
beginning the bottom waters occupies main part of the
Bornholm Basin (fig.4).

4. Conclusions
Model simulation made it possible to study different
features of saline bottom water inflow into the Bornholm
Basin. It sown main way of bottom water s spreading, its
evolution and interaction with upper layer.
