The study of landslides in the north-western Black Sea area has revealed significance of structural-tectonic peculiarities of rock massif for landslide scale, mechanism and slopes stability. Different methods were used to spot structural-tectonic weakness zones of different types. Dense disjunctive net (at characteristic tectonic intervals of 20-60 m) makes itself evident in two kinds of relief forms: in grating pattern of thalweg fragments of many small beams and gully and outlines of blocks of slip rocks and as outlines of slope edges at landslide sites. It has in particular been established that separate elements of landslides and erosion systems are most often regularly ‘organized’ in geological space. They rather develop in certain directions and with certain spatial interval indicating that they prepare some structural canvas of geological space. Monitoring of some buildings’ and engineering facilities’ state also shows that their deformations are caused by the reasons, which are regularly distributed in time and geological space. With that, publications dedicated to studies of underwater slope of landslide coast from engineering-geological viewpoint are scares. Interest in underwater part of landslide slopes is caused by the need in both engineering assessment of conditions for building of different facilities and forecasting of engineering-geological system behaviour. The latest cannot be reliable without knowledge of landslide slopes evolution regularities.
The purpose of the work is to reveal structural-tectonic discreteness of abrasion-landslide bench in a segment of the Black Sea landslide coastline in the area of Marine Hydrobiological Station of Odesa National I.I. Mechnikov University.
