The purpose of this work was to assess the hydrological effects of the impact of the Baltic Sea on the Polish coastal zone. The research area includes the Polish Baltic coastal zone, the Vistula River Delta, and the Baltic Sea coastal drainage basin. Man-made and land-based factors take part in this area. The most important hydrological effect is the change in sea level. The seawater intrusions is another effect of the hydrological activity of the Baltic Sea.
