Dynamics of the marine coastal zone of the sea near the entrance moles of the Kaliningrad Seaway Channel

Abstract

The results of multidisciplinary field studies of a segment of the coastal zone (in the area near the Baltiysk Strait South-East Baltic) are presented. The natural regime of the evolution of this zone has changed under the effect of anthropogenic factor. Bed topography, bottom sediments, and shore morphology and dynamics are characterized. The effect of entrance moles has resulted in the formation of various local hydrolithodynamic conditions on both sides of these moles, including the accumulation of sedimentary material and the seaward protrusion of the coastline in the north and the permanent erosion of the shore in the south. To reduce the adverse effect of hydrodynamic processes on the coastal zone south of the moles it is proposed to use the clean material extracted during strait dredging.
