| abstracts | The objective of this study is to determine differences between design wave heights determinedon the basis of short- and long-term wave trains. Wave parameters measured over a period of7.47 years in the vicinity of Coastal Research Station Lubiatowo were used as short-term wavedata, while wave parameters determined through the so-called wave reconstruction for a periodof 44 years for the same region and depth were used as long-term wave data. The results of thecalculations lead to the conclusions the significant wave height distributions obtained for shortand long-term wave data are similar. |

| abstracts | This paper analyses cross-shore bathymetric profiles between Władysławowo (km 125 of thePolish coastal chainage) and Lake Sarbsko (km 174) done in 2005 and 2011. Spaced every500 m, they cover beach topography from dune/cliff crests to a seabed depth of about 15 m.They were decomposed by signal processing techniques to extract the monotonic componentof beach topography and to perform a straightforward assessment of wave energy dissipa-tion rates. Three characteristic dissipation patterns were identified: one associated with largenearshore bars and 2–3 zones of wave breaking; a second, to which the equilibrium beachprofile concept can be applied; and a third, characterized by mixed behaviour. An attemptwas then made to interpret these types of wave energy dissipation in terms of local coastalmorphological features and the underlying sedimentary characteristics. |

| abstracts | The paper deals with the influence of the wave shape, represented by water surface elevationsand wave-induced nearbed velocities, on sediment transport under joint wave-current impact.The focus is on the theoretical description of vertically asymmetric wave motion and the effectsof wave asymmetry on net sediment transport rates during interaction of coastal steady cur-rents, namely wave-driven currents, with wave-induced unsteady free stream velocities. Thecross-shore sediment transport is shown to depend on wave asymmetry not only quantitatively(in terms of rate), but also qualitatively (in terms of direction). Within longshore lithodynamics,wave asymmetry appears to have a significant effect on the net sediment transport rate. |
