Research by the Polish Geological Survey has been carried out along the southern Baltic coastal zone over a distance of 38 km. The Baltic Sea is classified as non-tidal, and its southern coasts are built entirely of weakly lithified sedimentary rocks. These deposits form three main types of coast, namely cliffs, barriers and alluvial coasts (wetlands), with the research focusing on the first two. Methods including remote sensing, mapping (geological, hydrogeological), offshore survey (bathymetric and geophysical measurements), laboratory analyses and modelling revealed a number of natural hazards. These are, respectively: (1) permanently occurring hazards, causing material damage such as: landslides, coastal erosion and seabed erosion; (2) incidental hazards such as dune breakage and storm surge overflow and (3) hypothetical threats that may occur in the future, such as hydrogeohazards defined here as flooding resulting from groundwater level rise or more rarely, earthquake threats.

波兰地质调查局已在波罗的海南部沿海地区进行了38公里的研究。波罗的海属于非潮汐类，其南部海岸完全由弱石化的沉积岩构成。这些沉积物形成了三种主要的海岸类型，即悬崖，屏障和冲积海岸（湿地），而研究主要集中在前两个方面。包括遥感，制图（地质，水文地质），海上勘测（测深和地球物理测量），实验室分析和建模在内的方法揭示了许多自然灾害。它们分别是：（1）永久性危害，造成物质破坏，例如：滑坡，海岸侵蚀和海床侵蚀；
