The paper describes lithodynamic and morphodynamic processes occurring in the main part of the south-eastern Baltic coastal area, namely on the sea shores from the Vistula mouth in the Gulf of Gdansk to the Lithuanian-Latvian border. The study area is subject to intensive natural coastal changes, as well as shore evolution caused by anthropogenic impacts at several locations. Methods of coastal protection against erosion and shore stabilization systems applied in the past and currently are described. The paper deals with the causes of the dynamics of beach/dune shores and cliffs. It presents the authors’ field observations of 2010-2013, as well as previously gained knowledge and the results of Polish, Russian and joint Polish-Russian field surveys.

Mollusc shells from archaeological excavations are often well preserved and allow for species identification and measurements. Large shell assemblages can provide information for environmental reconstruction and investigation of anthropogenic impacts. In this study we compare freshwater mussel shells from a shell midden excavated on a lake island in northern Poland, dated 2,700–2,600 BP, with contemporary populations from that lake. No changes in species composition occurred, with only Unio tumidus and Anodonta sp. present in the prehistoric sample, and Unio tumidus and Anodonta anatina in the contemporary one. In both the archaeological and contemporary samples, shells of Unio tumidus were relatively small (mean shell length 49.3 ± 5.2 mm, max 64 mm, and 46.0 ±5.9 mm, max 61 mm, respectively). However, the values of all measured characteristics (length, height, mass, and thickness) were significantly lower in the contemporary compared to prehistoric shells. In modern times, in the region of the study largescale forest clearing and conversion of land into agricultural areas occurred; presently areas of intensive agriculture directly adjoin the lake. Dwarfing of the shells likely results from anthropogenic deterioration of mussel habitat.

W artykule zawarto informacje o dotychczas wykonanych pracach związanych z wdrażaniem Ramowej Dyrektywy Wodnej. W 2004 r. dokonano wstępnej oceny znaczących oddziaływań antropogenicznych i ich wpływu na wody. Prace te były podstawą utworzenia bazy danych niezbędnej do wykonania pogłębionej analizy oddziaływań i oceny ich wpływu, Zawartość merytoryczną bazy opracowano na podstawie metodyki Politechniki Krakowskiej, zmodyfikowanej przez zespół pracowników IMGW Oddział w Krakowie na podstawie doświadczeń z jej wdrażania. Doświadczenia zdobyte przy wykonywaniu tego zadania wykazały brak jednorodnych numerycznych baz danych w Polsce, a co za tym idzie konieczność utworzenia bazy danych, spełniającej warunki narzucone przez RDW. W 2005 r. wykonano projekt bazy, do której dołączono dostępne dane oraz wskazano sposób pozyskania pozostałych. Zaprojektowano zawartość merytoryczną bazy danych, składającą się z 44 zbiorów posegregowanych w pięciu grupach funkcyjnych. Uzupełnienie danymi zaprojektowanej bazy daje możliwość ponownego, pogłębionego określenia oddziaływań antropogenicznych i oceny ich wpływu na wody powierzchniowe i podziemne oraz ustalenie części wód zagrożonych nieosiągnięciem celów środowiskowych.

The article contains information on the hitherto conducted works related to the implementation of the Framework Water Directive. In 2004, a preliminary analysis of the significant anthropogenic impacts and their influence of waters was conducted- Those works were the basis to create a database necessary to perform a detailed analysis of those impacts and an assessment of their influence. The factual contents of the database were elaborated with the use of Krakow University of Technology's methodology, modified by a team of specialists of the Institute of Meteorology and Water Management, Division in Krakow, on the basis of experience acquired during its imlementation. The experience acquired at the realisation of this task indicated lack of uniform numeric databases in Poland and, therefore, the necessity to create a database fulfilling the requirements imposed by the Framework Water Directive. In 2005, a draft version of the database was prepared, including the a available data and indicating method to acquire the remaining information. The factual contents of the database were designed - 44 sets divided into five function groups. The supplement of the designed database gives the possibility of repeated, deepened determination of the anthropogenic impacts and assessment of their influence on surface and underground waters, as well as identification of waters that may not achieve the environmental objectives.
