The paper deals with the sandy coastal zone at Lubiatowo in Poland (the south Baltic Sea). The study comprises experimental and theoretical investigations of hydrodynamic and lithodynamic processes in the coastal region located close to the seaward boundary of the surf zone and beyond the surf zone. The analysis is based on field data collected at the IBW PAN Coastal Research Station in Lubiatowo. The data consist of wind velocity reconstructed from the long-term wave climate, deep-water wave buoy records and sea bottom soil parameters. Nearbed flow velocities induced by waves and currents, as well as bed shear stresses are theoretically modelled for various conditions to determine sediment motion regimes in the considered area. The paper discusses the possibility of occasional intensive sediment transport and the occurrence of distinct sea bed changes at bigger water depths.

The article is concerned with links between the ideas of Konrad Lorenz (1903-1989) and several topics in aesthetics. Lorenz was one of the most interesting and influential biologists of the twentieth century, and aesthetics played an important role in his work. The first part of the article considers the characteristic features of 'Lorenz's aesthetics'. His thinking follows on from Darwin and Darwinian ideas, and also reveals the strong influence of traditional German ideas of nature (for example, those of Goethe). For Lorenz the beauty or attractiveness of natural objects is always linked with usefulness, but not strongly determined by use. Bird songs, for example, are more beautiful, more complicated when they are sung without a purpose. Lorenz also based his theory of aesthetic perception on Gestalt psychology, thus placing emphasis on the whole. Landscape is more beautiful when its complexity and its 'health' are on a higher level; a landscape without biodiversity or one that is too simple (for example, industrial, modern agricultural, or monocultural landscapes) are objects of low aesthetic value. In the second part of the article the author traces some of Lorenz's ideas on the origin of art and culture. Lorenz links these origins with play (following on from Friedrich Schiller) and ritualized behaviour supported by 'Funktionslust' (delight in performing a skill well), which grows in the process of mastering complicated movements. For Lorenz, ceremonies (or rituals) bind human (and animal) society together.

The paper deals with the natural sandy nearshore zone, located close to Lubiatowo in Poland (the south Baltic Sea). The study site is characterised by multi-bar sea bottom profile, intensively dissipating wave energy. The paper presents a verification of the depth of closure concept. The analysis and theoretical considerations are based on field data collected at the IBW PAN Coastal Research Station in Lubiatowo. The data comprises cross-shore bathymetric profiles and the deep-water wave buoy records. The depth of closure determined from bathymetric surveys was found to be bigger than the one calculated using parameters of the effective significant wave height.

Artykuł dotyczy naturalnej piaszczystej strefy przybrzeżnej znajdującej się w pobliżu Lubiatowa w Polsce (południowy Bałtyk). Miejsce badań charakteryzuje się wielorewowym Profilem dna morskiego, powodującymi intensywną dyssypację energii fal. Praca przedstawia weryfikację koncepcji głębokości zamknięcia. Analiza i rozważania teoretyczne opierają się na danych terenowych zebranych w Morskim Laboratorium Brzegowym IBW PAN w Lubiatowie. Dane te zawierają profile batymetryczne poprzeczne do brzegu oraz rejestracje z głębokowodnej boi falowej. Głębokość zamknięcia wyznaczona z pomiarów batymetrycznych okazuje się większa niż obliczona z parametrów efektywnej fali znacznej.

The paper presents results of field and theoretical investigations of a natural sandy shore located near the IBW PAN Coastal Research Station in Lubiatowo (Poland, the south Baltic Sea). The study site displays multi-bar cross-shore profiles that intensively dissipate wave energy, mostly by breaking. The main field data comprise offshore wave parameters and three cross-shore bathymetric profiles. Waveinduced nearbed velocities and bed shear stresses are theoretically modelled for weak, moderate, strong and extreme storm conditions to determine sediment motion regimes at various locations on the seaward boundary of the surf zone. The paper contains a discussion on the depth of closure concept, according to which the offshore range of sea bottom changes can be determined by the extreme seasonal deep-water wave parameters.

The paper presents experimental and theoretical investigations of hydrodynamic processes in a coastal region located close to the seaward boundary of the surf zone. The analysis is based on field data collected near Lubiatowo (Poland) by measuring equipment operated simultaneously by the Institute of Hydro-Engineering of the Polish Academy of Sciences (IBW PAN) and the Maritime Institute in Gdańsk (IMG). The data consist of wind velocity and direction measured at the IBW PAN Coastal Research Station (CRS) in Lubiatowo, deep-water wave buoy records, current profiles and sea bottom sediment parameters. Mean flow velocities measured in the entire water column have almost the same direction as wind. Nearbed flow velocities induced by waves and currents, as well as bed shear stresses, are modelled theoretically to determine sediment motion regimes in the area. It appears that the nonlinear wave-current interaction generates bed shear stresses greater than those that would result from the superposition of the impacts of waves and currents separately. The paper discusses the possibility of occasional intensive sediment transport and the occurrence of distinct seabed changes at greater coastal water depths adjacent to the surf zone. It was found that this can happen under the joint influence of waves and wind-driven currents.
