| Abstract: | We present a numerical model of the dynamics of the Kerch Strait allowing one to perform the coordinated analysis of the fields
of currents and wind waves. The model includes the spectral wave module and the hydrodynamic block of currents. The influence
of waves on the currents is taken into account in the hydrodynamic block both via the surface and bottom tangential stresses
and via the radiation stresses. In order to take into account the inverse influence of currents upon the waves, we use the
fields of currents and sea level from the hydrodynamic block in the wave module. The specific features of the structure of
currents and wind waves in the strait are studied for the typical wave situations. The results of the coupled and separate
simulation are compared and the importance of taking into account the mechanisms of interaction between waves and currents
in the analysis of the dynamic processes in the strait is demonstrated.
