ABSTRACT
Hydrodynamic circulation in the marine environment, characterized by the
effects of the intense tide conditions, the atmospheric loading, and the
bathymetry, constitutes a complex phenomenon. The present paper deals with the
numerical simulation of the hydrodynamic circulation of the Gulf of Evoikos,
which is characterized by the existence of a strong tide. The Estuarine and
Lake CΟmputer Model three-dimensional hydrodynamic model has been used, which,
besides the tide, takes into consideration the atmospheric forces acting on the
surface of the study area, such as the solar radiation, the atmospheric
pressure, the relative humidity, the rainfall height, the air temperature and
the wind speed and direction. The physical and hydrodynamic characteristics of
the water circulation under tide conditions are examined such as the salinity,
the water temperature, the density stratification, the flow velocities, the
tracer concentration, etc. These characteristics are absolutely critical for
the diffusion and dispersion of passive pollutants, the water flow renewal, and
the general environmental situation.
