Dynamic processes at the mouth of the Wisła Śmiała River

The coastline changes, which occurred at the mouth of the Wisla (Vistu)a) Śmiala River until 1993, are presented. Coastline accretion on the western side, and retreating on the eastern side of the river mouth have been observed. Narrowing of the mouth due to accumulation of sand have also been noticed. The character of coastline changes allows the conclusion that the coastline have been naturally returning to the position of 1840.
