Important Features of Coastline Dynamics in Poland: “Nodal Points” and “Gates”
Two phenomena and their regularities, which are characteristic for the coastal zone, are presented in this paper. During the investigations, several series of historical aerial photographs of the Polish coast were utilised. The first phenomenon is connected to coastline changes and their regularities. Along the coast, stable areas and regions with high dynamics with respect to erosion and accumulation were found. Cross-shore current systems are linked to these stable points, called “nodal points”. The second investigated phenomenon are so-called “gates”. Gates are areas of the coastal zone, where spatially persistent cross-shore currents are observed. The importance of these aspects for coastal zone management is discussed.
