Since it is between the inflow of freshwater form rivers and sea saltwater, in its natural state it would be an area with freshwater wetlands, barene (saltmarshes), velme (mudflats), and lagunar channels which forms a transitional belt between the mainland and the open lagoon rather than forming a fixed boundary, with its conformation changing according to the interplay of the hydrodynamic forces of the lagoon and their hydrodynamic equilibrium.
