Algorithm for selecting the structures of coastal protection construction to ensure environmentally safe condition of the coastal urbanized recreational areas

Abstract

The existing concepts and modern methods of ensuring the ecological safety of the coastal zone of the sea were analyzed. The article considers modern theoretical developments and methods of choosing design solutions for special structures – various coastal protection structures (permeable, impermeable, made of various building materials, various shapes). This paper suggests a new algorithm for the choice of Bank protection structures intending to ensure environmentally friendly seaside state urban recreation area from the position of the preservation or restoration of the beach zone, which affects the environmental parameters of the site, which consists of a data collection phase of the study object, the selection of natural and technical factors that affect the ecological security of seaside urban recreational areas, the definition of specialization of the coastal zone in terms of recreation attractiveness of the coast, the evaluation phase of the current dynamics of ecological safety of the beach zone of the shore as an important element of seaside recreation of the urbanized area, which affects the level of environmental security in general, stage select bank protection structures and the definition of the projected factors of ecological safety of the beach zone. To check the application of the algorithm of selection structures bridges to ensure environmentally safe condition seaside urban recreational areas allows further justify the selection of the optimal environmental engineering solutions for the protection of the Western coast of Crimea.

Environmental problems of the Crimean coast territories

“…At the same time, the presence of calcareous monoliths in the underwater part of the sea near the village of Uglovoye was previously revealed. The formation of underwater elevations by 1-3 m leads to the transformation of the shore and waves -a change in their internal structure and external shape along the route [15] and according to the results of the survey of these sites it can be concluded that the identified process of formation of underwater elevations leads to the preservation of the beach width in this place.…”

“…This confirms the conclusion that the implementation of previously local coastal protection measures did not allow solving the problems in a complex. Long-term field observations [16] show that the creation of coastal protection in certain local areas gives only a temporary positive effect and can have very negative effects on neighboring areas of the beach territory, without considering the patterns of directions of long-shore sediments and wave loads. Consequently, the coastal protection issue should be resolved within the boundaries of morphological units of territories, considering the conditions of a single system.…”
