Hydraulic model investigation of Świna Strait

The paper concerns hydraulic model investigation of the area of the Świna Strait as a whole and part of it conducted in the laboratory of the Institute of Hydro-Engineering of the Polish Academy of Sciences (IBW PAN) over the past fifty years. The Świna Strait is part of the Odra Estuary, located on the southern coast of the Baltic Sea. The inlet structure (I Brama Torowa) located at the entrance from Szczecin Bay to the Piastowski Canal is a very important part of the waterway between the Pomeranian Gulf and the Szczecin Bay. In connection with modernising work, a detailed study of the Świna Strait and region of the inlet structure was carried out on hydraulic models. The paper presents basic information on physical models. Some examples of the solution of engineering problems in the Świna Strait, on the basis of the results from model tests performed in IBW PAN, are described. A description of the models, the way of performing the experiments, investigated variants and results obtained are presented.
