Abstract (English):
Detailed studies of landslide formation on the continental slope of Near Caucasus part of Black Sea, we have made in the area between the Pshada– Olginka settlements allowed to explore the distribution of landslide formations on the continental slope and to establish their influence on the retreat of the shelf edge. The intensive destruction of shelf edge leads to a reduction in its width, the intense movement of sediments from the shelf and transporting them to the continental slope and deep-sea part in large quantities. The evolution and distribution of landslides are influenced by the geological structure of the navigation area, the width of the shelf, the rate of shoreline destruction and sediment transport from the shelf to the continental slope, underwater topography and slope declination, tectonic and seismic factors. Landslide processes on the coast and continental slope affect the modern coast changes, the bottom topography, the formation of Black Sea deep basins and the expansion of Black Sea. Coastal landslides pose a threat to coastal communities and national economic objects located in areas of high abrasion scarps of terraces, as well as for engineering structures on the continental shelf, continental slope and the seabed.
