“…Another fact is that, after the start of open-pit mining of amber in 1914 and, especially, after the mass discharges of Amber Plant overburden into the sea since 1958 [9,19], beaches 80-100 m in width, with vestiges of a young avandune, and a continuous stratum of aleurite sands (0.05-0.25 mm) down to depths of 15-20 m have formed at the discharge site and within the Baltic-Yantarnaya arc [5,8,42]. At the same time, the dynamics of the shore and the submarine slope of the Vistula Spit south of the moles has not suffered considerable changes [11,19,42,50], i.e., the southern boundary of mass migrations is situated abeam of the entry moles of the Baltic Strait.…”

The published schemes of the net alongshore sediment transport near the eastern coast of Gdansk Bay have been systematized. Considerable discrepancies have been identified in the structure and localization of the convergence zones of opposite currents. The results of station-based measurements of bottom currents near the Strait of Baltiysk at depths of 6-16 m were used to show that, at winds >6 m/s, the alongshore currents run along the alongshore wind component. The morphodynamic accumulation (filling of the entry corner and abrasion in the shadow zone of the obstacle) and abrasion (orientation of the abrasion depression at the extreme end of the harbor moles) criteria are discussed. The abrasion criterion is shown to work better than the accumulation criterion in determining the net sediment transport in the coastal reaches with a normal or near-normal approach angle of the wave energy flow toward the shore. The specific features of the mechanism of sediment transport from south to north, by-passing Baltiisk harbor moles, from the abrasion to accumulation shore segments are given. Two schemes of the opposite Vistula and Sambian alongshore sediment flows are proposed: before the construction of the entry harbor moles in the Baltic Strait with a vast migration zone near the northern end of the Vistula Spit and after the construction of these moles, which has narrowed this zone and shifted its southern boundary northward toward the moles.

“…The bedload transport in the study area is not well recognized. Some estimations of the sediment transport rate were performed for the eastern part of the Gulf of Gdańsk (Kaczmarek et al 2010;Ostrowski et al 2010;Chechko et al 2015). However, all of those studies were focused on the processes taking place at water depths of up to 10-13 m. The occurrence of sediment transport at depths greater than 15 m is mentioned by Uścinowicz et al (2014) as well as in some documents related to the commercial projects and unpublished materials.…”

Assessment of the potential for dredged material dispersal from dumping sites in the Gulf of Gdańsk

Purpose Environment-friendly management of sites used for disposal of locally generated sedimentary material involves designation of an optimal dumping site location which will render the dredged material re-usable for beneficial purposes. The objective of this research was to determine whether wind, waves, and currents can induce transport of sediment from offshore dumping sites located at intermediate depths in the southern Baltic. Materials and methods The problem was addressed by exploring potential sediment transport from two sites located in the Gulf of Gdańsk at depths of about 20 m. A total of 29 combinations of hydrodynamic variables, representing the most extreme possible situations in the area, including eight theoretical uniform wind fields over the entire Baltic Sea from the W, NW, N, NE, E, SE, S, and SW sectors, the wind speed of 30 m s −1 , as well as 21 historical extreme storms, retrieved from the HIPOCAS project database, were used. Results and discussion The bottom velocities resulting from waves and currents at the dumping sites considered were computed using wave models (WAM, SWAN) and the M3D hydrodynamic model (based on the POM model). To estimate the velocities critical for bedload transport, formulae developed by Soulsby (1997) and Sawamoto and Yamashita (Proc Coastal Sediments 87:415-423, 1987) were used. The volumetric bedload transport was computed based on Meyer-Peter and Müller (1948). The model simulations demonstrated that, for the storm conditions analyzed, the current velocity in the area of the two dumping sites would be so low that it would practically not affect the magnitude of the bottom sediment transport. Thus, the resultant volume of bedload transported would be equal to that generated by the wave action. For the heaviest historical storm, the maximum transport is about 3 × 10 −5 m 2 s −1. Conclusions Under conditions of theoretical storms, the bottom orbital velocities would be higher and the resultant sediment transport would reach almost 7 × 10 −5 m 2 s −1 for northerly winds. However, this value is still very low compared with the volume of sediment being dumped. The findings of this study may prove useful in designation of future dumping sites.

“…Its eastern basin provides 1.5 km 3 of this capacity or 64.0% of total water volume. Originally, the Lagoon connected with the extensive backwaters and marshes inside the Vistula delta and had at least periodic connection with the Baltic Sea (Chechko et al 2015).…”

The purpose of the paper is to provide some calculations on the current water balance for the Vistula Lagoon, which is exceptionally valuable in terms of biology and hydrology. It is located along the southern coast of the Baltic Sea in both Poland and Russia. In the era of marked climate change, but first and foremost the plans of the Polish side of the cross-cutting of the Vistula Spit, there has been a need to update the balance data of the Vistula Lagoon. In the near future, they may be an excellent comparative material to changes in the proportions of individual water circulation components in the Vistula Lagoon and changes in its entire ecosystem, caused by the implementation of the project. In the literature on the subject, balance sheet data from 50 years ago are used (these data were compiled in the initial part of the study), hence the concept of attempting to update them has appeared. Due to the lack of data from the Russian part of the catchment area, the main emphasis in the work was put on the completion and modernization of the components of the balance sheet of the Polish catchment. A novelty at work is the refinement of the potamical inflow to the Vistula Lagoon with small but numerous streams flowing from the Elbląg Upland, as well as the inflow forced by polder discharges. Climate water balance data are shown based on data available from IMGW in Warsaw and include monthly precipitation totals for the period 1996–2010 obtained at six gauging sites located near the Vistula Lagoon. Evaporation was calculated using Tichomirov’s formula. River water influx was determined based on data available in Kruk (2011), data from IMGW (Pasłęka River) and data from papers Bogdanowicz (2007, 2009) and documents associated with the Program for biological passages in rivers in Warmińsko-Mazurskie Province (2007). Raw data were also obtained from the Office of Water Management in the city of Elbląg for the period 2006–2011. These data covered water flow moving from the polders. Groundwater influx was estimated using values provided by Silicz (1975). The volume of seawater influx was estimated using the data provided by Silicz (1975) and Chubarenko and Chubarenko (2002). The study confirms that water exchange in coastal lagoons is quite complex due to the presence of several different sources of recharge and several different places where water is lost. The complexity of water cycle is enhanced by a complex hydrographic system of lagoon catchments and a complicated system of water exchange with the sea. The total water volume involved in circulation in the Vistula Lagoon is estimated to be 24,225 mln m3 per year. The largest part of the water received by a coastal lagoon comes from the sea. In this case, it is about 77% (18,130 mln m3 per year). In addition, an array of catchment sources yields about 21% of the studied lagoon’s water. Its catchment provides an additional 4,974 mln m3 of water. The Pregolya River produces 55% of the catchment influx. The volume of water forcibly produced by area polders is so small that it does not produce an observable effect on the water balance in the Lagoon (about 0.04% of total influx). The precipitation constitutes 2.3% of the power supply source of the Vistula Lagoon. On the other hand, the Strait of Baltiysk constitutes the main outflow pathway for water exiting the Vistula Lagoon – close to 98% of all outflow (23,694 mln m3). The remaining 2% is lost due to evaporation.
