Hydrological Regime and Lithodynamic Processes in the Mezen River Estuary

Abstract

In the Mezen River estuary, morpholithodynamic processes are regulated by tidal currents, river runoff, wind waves, and alongshore sediment flows. Due to the movement of a huge mass of sediments in the Mezen River estuary, intense deformations of silty sand banks occur, reforming the bottoms of channel grooves and displacing navigable waterways. On the whole, the Mezen River estuary is gradually being filled with river and marine sediments. Various sandy ridges form in the channel grooves of the estuary.
