LANDSLIDES OF THE SEVASTOPOL REGION.PART 3. MRAMORNAYA CLOUGH – CAPE AYA

Yu.N.Goryachkin, A.P.Fedorov

Abstract
The geomorphological, geological, lithological, and hydrological conditions of the coastal section from the Mramornaya Clough to the Cape Aya (Sevastopol Region) are considered in connection with dangerous exogenous geological processes. It is shown that the coast is exposed to a complex of landslide, abrasion, erosion, karst, rockfall, mudflows. For the main causes of occurrence and development, natural, man-made and natural-man-made landslides have been identified. It is noted that out of 34 landslides on the Mramornaya Clough to the Cape Aya: 22 of natural origin, 11 of natural and man-made and one of man-made. Landslides of natural and man-made origin have arisen as a result of slope over-wetting after their terracing and fires (destruction of vegetation). It is shown that there is no abrasion in areas where there are practically no limestone and conglomerates at the cliff base. Currently, there is a significant shortage of beach savings, beaches do not have sufficient recharge, as they are formed mainly due to local abrasion and outflows of soils into the coastal zone.
