The article describes the nature and degree of deformations of the coastal zone of the sea and coastal protection structures on the coast of the Kalamitsky Gulf of the Black Sea. In 2022, a team of authors made a visual survey of the coast on the territory of the Bakhchisarai district of the Republic of Crimea with a total length of 11.5 km. from the village of Beregovoe to the village of Uglovoye. As a result of the inspection, coast areas potentially dangerous for human health and life that are not suitable for normal use for recreational purposes were identified. Long-term field observations show that the creation of coastal protection in certain local areas, giving only a temporary positive effect for these areas, can have a very negative impact on neighboring and even remote areas; that is why the coastal protection issue should be solved at least on the scale of the coast of settlements, considering the conditions of a single system. When designing coastal protection measures, it is necessary to consider that separate protection of small areas of erodible coastal territories within a large area of the eroded coast is ineffective, since adjacent unprotected shores will recede under the action of a system of natural factors.
