Abstract
The characterization of lithodynamic processes in the littoral part of the Odessa Bay was carried out based on the analysis of irregular field observations of the beach zone, analysis of the hydrodynamic regime, granulometric analysis of beach and littoral deposits, analysis data on coast morphology and coast behavior, analysis of archival materials and publications.
Odessa Bay is a lithodynamically active zone. The lithodynamic regime of the bay is characterized by seasonal variability, which is due to seasonal changes in the directions and intensity of bottom currents. In general, lithodynamic flows in the coastal part are directed from northeast to southwest. They run along the coastline, deviating to the southeast in the southern part of the bay.
Under conditions of changes in the hydrodynamic regime of the Odessa Bay due to climate change and anthropogenic impact on the coastal zone, a qualitative study of modern lithodynamic flows will make it possible to qualitatively design modern active-type coastal protection structures that can ensure the release of natural sand and the formation of beach deposits, which will help reduce coastal abrasion.
