abstractsThis article shows how dumping of sediments from an amber mining plant prevented erosion of the western shore of the Sambian Peninsula (in Kaliningrad Oblast). The average annual dynamics of coastal areas in the vicinity of the former dumping site of the amber mining plant is described. Nowadays the erosion is continuing after cessation of dumping. The rate of erosion was estimated by results of regular monitoring measurements, using airborne laser scanning. It was found that about 250000 cubic meters per year of local material is needed every year to prevent further erosion and retreat of the shore.

abstractsIn order to make a navigable connection between the Vistula Lagoon and the Baltic Sea independent of an attitude of the Russian authorities, a cross-cut in the Polish part of the Vistula Spit is planned. The cross-cut will constitute an alternative waterway with respect to the existing one, leading through the Pilawa Strait which belongs to the Russian territorial waters. The new outlet will require breakwaters and an approach channel on the open sea side, as well as a waterway across the Vistula Lagoon to the harbour of Elbląg. The planned cross-cut is located about 3 km from the root of the Vistula Spit, at Skowronki village. The paper comprises an analysis of regional wave parameters in a mean statistical year on the basis of the Baltic wave climate reconstructed for the period of 44 years, together with a calculation of the longshore sediment transport rates. An influence of the planned coastal structures on the shoreline evolution, as well as the approach channel silting-up rates, in the first 10 years after the construction of the cross-cut, are estimated. An optimised layout of the planned approach channel and lengths of the planned breakwaters are recommended to facilitate the maintenance of the coast and the new waterway.

abstractsThe paper presents new findings concerning motion of water and sediment in the coastal zone of the east part of the Gulf of Gdańsk, from the Vistula River mouth at Świbno (Poland) to Cape Taran (Russia, Kaliningrad Oblast). The presented study deals with spatial variability of parameters of hydrodynamic and lithodynamic processes which have been subject to theoretical modelling. For the considered coastal segment, deep-water wave conditions reconstructed for a 44-year period have been analysed and transformed to the nearshore zone. Next, velocities of wave-driven longshore currents for the mean statistical year have been calculated, along with the longshore sediment transport rates. Regarding the net longshore sand motion, its detected direction is from Cape Taran towards the Vistula Spit. Very high annual rates of longshore sediment transport have been obtained for the coastal segment at Sambian Peninsula. These rates decrease considerably along the Vistula Spit, reaching zero at a distance of about one third of the Polish part of the Spit, measured from its root. At this location, the net longshore sediment transport (resulting from net longshore wave-current impact) reverses from westward to eastward.

abstractsThe history of the Vistula River mouth exhibits the development of the hydrographic system of Żuławy lowlands caused by natural phenomena and human intervention. During its history, the Vistula River has changed the location of its direct connection with the Baltic Sea three times; the first (the Gdańsk Vistula) and the second (the Brave Vistula) river outlets were created by nature, while the recent one (the Vistula Cross-Cut) was man-made. Each of these locations faced similar problems, i.e. sedimentation in the river mouth leading to flooding problem in the surrounding region, intensified in winter by ice jams. The recent outlet, made as a short cut of the river reach in 1895, requires permanent maintenance as to diminish a flood risk for the surrounding areas due to sedimentation. Since the opening, its maintenance is carried out by elongation of jetties on both sides of the river mouth, and occasional dredging of sand. Presently, further elongation of jetties is proposed, however new methods to keep the river mouth should be considered.

titleWave climate in the Gulf of Gdańsk vs. open Baltic Sea near Lubiatowo, Poland

abstractsThe paper analyses long-term variability in the wave climate near Lubiatowo, ca. 15 km east of Łeba harbor, and in the Gulf of Gdańsk, near the Vistula river mouth. The wave climate was reconstructed for the 1958-2001 period by the German Institute for Coastal Research (GKSS). Using basic statistical tools - empirical mean values of significant wave height, estimation of the number of threshold crossings above a prescribed value of that height and conditional empirical probability density functions of wave approach directions - a comparison of wave height at the two locations was executed. A substantial reduction in wave height inside the Gulf (sheltering effect) was measured. Further, the increased storminess over the winter season was estimated for the open sea location. Finally, the analysis of wave approach direction in the open sea location revealed substantial growth in extreme waves from the western sector. Given the geographic configuration of the Gulf and the combined rise in storminess and evolution in extreme wave direction, it can be inferred that the sheltering effect of the Gulf can vary depending on locations within the Gulf. Identification of sheltering patterns in the Gulf emerges as obvious follow-up research. This study could also prove useful in analyses aiming at integrated management of coastal zones in the Gulf, mainly in the implementation of Coastal Protection Law (Apr. 2003), which postulates maintenance of the 2001 shoreline configuration along the entire Polish coast.

titleWind-driven currents and their impact on the morpho-lithology at the eastern shore of the Gulf of Gdańsk

abstracts

The paper presents results of a study of near-bottom currents, lithology and morphodynamics on the shore-zone of the Vistula Spit in Russia and on the western shore of the Sambian Peninsula. The measurements were conducted in 1991 and during the period of 2005–2009. The study involves the analysis of the synchronous and statistical parameters of the currents together with wind, grain-size and sorting coefficient distributions for the deposits of the beach and underwater slope, and also the analysis of the morphology and morphodynamics along the east coast of the Gulf of Gdańsk. It has been shown that under conditions of an acute angle between the seaward wind vector and the coastline the strongest and the most stable longshore currents are formed. An increase of the angle leads to a decrease of velocity and stability of these currents. Under conditions of the wind normal to the shore (90º) in the sector of the curved coast Yantarny – Baltiysk (west wind), convergence of the currents is observed. The assessments of annual capacities of the longshore sediment transport for the coastal segment at the Sambian Peninsula and the deformation volumes on the underwater slope at Baltiysk are summarized.

A hypothesis is proposed that the sector of 5–15 km north of Baltiysk under the existing wind-wave conditions is the zone of convergence and the discharge-resulting sediment transport.

The assumption of the prevalence of migratory and whirl circulations along the shore zone of Vistula Spit is put forward.

It is noticed that entrance moles of Baltiysk considerably impact on parameters of the currents and flow of deposits along the coastline at the length of 3–4 km.
