Study of the Flow Dynamics of Surface Water Masses in the Area of the Coastal Gulf of Gdansk

The paper describes method for predicting the movement of surface water masses on the maritime areas adjacent to the port. Method uses the theory of graph. The results in virtual environment were related to the measurements taken in the real world. For experiments were used drifters whose construction allowed to move only with the surface water masses. Analyzes of data obtained during real-world experiments were the basis of numerical experiments that used the graph theory. Studies were carried out to provide the tools to determine the migration of contaminants generated in the port areas of Gulf of Gdansk. The research results can support coastal states with the requirements laid down in the European Water Framework Directive.
