ABSTRACT

The coastal sector in the Black Sea at the mouths of the Danube River represents one of
the main entrances in the VII Pan European Transportation corridor, which is an
important logistic chain for the inland navigation in Europe. As a consequence, this area
is subjected to both enhanced navigation traffic and high risks of coastal hazards. In
this connection, the objective of the present work is to evaluate the navigation
conditions in this important coastal environment of the Black Sea. The main part of the
work is focused on evaluations of the wave transformation patterns, especially as
regards the strong wave-current interactions that often occur in the Black Sea in front of
the Danube Delta and which can significantly affect the safe navigation conditions.
Such phenomena are due to the relatively intense currents induced locally by the
Danube River outflow combined with the high waves that periodically occur in this
coastal environment. The evaluation of the wave-current interactions and of their effects
on the coastal navigation is performed using SWAN spectral wave model. The
numerical simulations carried out following the main patterns for the waves and
currents show that the above interactions may locally generate very strong waves both
in terms of significant and maximum wave heights. Such phenomena can represent a
real threat for the navigation conditions and can be a serious source of coastal hazards.
