Modelling for impact assessment of new port development in the Vistula Lagoon, the Baltic Sea

Abstract

The results of the environmental impact assessment of the new port development in the South-eastern Baltic is discussed. The following parameters were evaluated: (a) concentration of suspended matter; (b) exceeding of the 10 mg/l limit for suspended matter; (c) spatial distribution of sedimentation; (d) changes of discharge in the pass between navigational canal and some parts of the Vistula Lagoon; (e) impact on surplus-concentration and extent of the increased water exchange between the canal and the lagoon. The positive and negative consequences of the port development are discussed.
