PROJECTED CHANGES IN THE HYDROLOGICAL CONDITIONS OF THE VISTULA LAGOON UNDER INFLUENCE OF NEW NAVIGABLE CHANNEL THROUGH
THE VISTULA SPIT
As a result of a query performed using source materials and field studies found that the biggest problem for the Lagoon to create a channel through the Vistula Spit, just at the stage of construction and operation will be muddy water due to exhaustion from the bottom land of the content dusty-clay particles and organic (silt). In addition to increased turbidity may occur (depending on the type of pollutant and its concentration) effects caused by the release of organic matter and toxic substances and biogenic compounds deposited in the sediments (increased biological oxygen demand and the impact of toxic substances). Changes in salinity of the water in the Vistula Lagoon can occur only locally and in a very small degree. The primary source of salinity of the Vistula Lagoon will remain stormy waves of the Strait of Baltiysk. The natural conditions of hydrodynamic and water hydrology on the Vistula Lagoon will not be materially changed and will continue to depend on meteorological and hydrological conditions at sea.
