The purpose of this work is to comprehensively study the ecological and geological conditions and results of monitoring studies of the coastal territories of the Bay of Taganrog and the Sea of Azov to identify indicators for assessing natural risks. The object of research is a complex system of the coastal zone, consisting of subsystems of land, sea and coast. The subject of the study is the assessment of the risk of loss of territory as a result of various natural factors, both constant over time (geological structure, height of the coastal cliff) and changing (dynamics of the level, waves, wind conditions). Within this framework, we show the use of a dynamic approach for zoning the shores of the Sea of Azov, performed based on a comprehensive analysis of natural and anthropogenic factors that determine the development of dangerous coastal processes (DCP). All factors divided into two groups: those that increase the intensity of coastal processes and those that contribute to reducing their manifestations. It established that hydrodynamic factors in the development of DCP are the determining factors. Anthropogenic impact can be associated with both global and regional impacts, through ecosystem changes, regulation of river flow, environmental pollution, and local – irrational coastal protection, industrial and agricultural activities in the coastal zone, unauthorized removal of beach material, etc.

Bottom sediments formed in the water bodies under the technogenic impact are important environmental factors affecting water quality and hydrobiota. Usually they consist of natural and technogenic material and differ from natural formations by their morphology, chemical and lithological composition, physicochemical and biochemical properties. In the present paper we use the term “sediment layer of anthropogenic impact” to define the sediment layer containing technogenic material and/or chemical pollutants. The determination of its location in the sediment cores, its thickness and accumulation chronology is an important scientific problem. In the paper the results of layer by layer study of Cs-137, Am-241, Pb-210 specific activities as well as concentrations of petroleum components, lead and mercury in 48 sediment cores of the Sea of Azov and the Don River are examined. The sediment core layers are dated by radiological methods. In all the sediment cores the peak of Cs-137 specific activity related to the Chernobyl accident was detected. In the Sea of Azov, this peak is located in the upper sediment layer up to 10 cm thick, however, in the delta and in the near-delta part of the Don River, where the sedimentation rates are more important, it is found at 20 to 40 cm depth. Also in certain sediment cores the second peak of Cs-137 related to the global nuclear fallout of the 1960s was found. The most of petroleum components, lead and mercury quantities are concentrated in the upper sediment layer formed in the last 50 to 70 years, i.e. in the period of the most important anthropogenic pressure. So, this complex approach based on the data on the vertical distribution of technogenic radionuclides and common pollutants in the sediment cores made it possible to identify and delineate the sediment layer of high anthropogenic impact as well as to assess the duration of this impact.

The Impact

Coastal zones are integral natural and socio-economic territorial-water system, combined by a complex structure of interactions. Coastal geosystems are unique, rich in natural resources, which determines their attractiveness for industrial and residential, recreational, transport and other activities, but also makes them environmentally vulnerable. Sustainable development of the coastal zone is determined by the economic, social, and environmental components. The research area of interest is the coastal zone of the Sea of Azov (Rostov Region). The subject of the study is the state of medical and environmental safety of the territories. The purpose of the study is the analysis of medical-ecological and socio-demographic factors as the basis for sustainable development of the coastal zone of the Sea of Azov. A systematic approach has been implemented to assess the sustainable development of the coastal zone and to develop methods for analyzing and integrating heterogeneous data. Changes in the coastal zone were evaluated based on a comparative analysis of multizone satellite imagery with ground-based studies, data from thematic maps. For the analysis of medical and environmental safety, an author’s technique was used, combining traditional methods and geoinformation technologies based on ArcGis Desktop*. The environmental quality indicator was considered in terms of the impact on human health. Assessment of demographic security was carried out based on the coefficient of demographic well-being / prosperity of the territory. The incidence rate of malignant neoplasms was considered as a highly informative and socially significant indicator of the health status of the population. For analysis, we used the SSC RAS database for 2006-2016. A comprehensive analysis of the development factors of the coastal zone of the Sea of Azov showed significant problems in the studied region. The most attractive areas of the coastal zone of the Sea of Azov from the point of view of infrastructure development are at the same time subject to changes due to dangerous natural phenomena. Analysis of demographic indicators confirmed the presence of adverse demographic processes.

Identification of patterns of formation of regional environmental and socio-economic problems in the system “society–nature” and on this basis—to ensure public safety and minimize the economic damage social infrastructure are the main objectives of the study. The object of research is the coastal zone of the Sea of Azov (Russian sector) The subject of the research is a comprehensive analysis of the factors of sustainable development of the coastal zones of the Azov Sea region (Russian sector) based on an integral approach. The paper considers methods for constructing a comprehensive risk analysis model for the coastal zones of the Azov Sea region (Russian sector), which should consider various influencing factors of coastal risks at the same time. The analysis of the main indicators of medical, social, and demographic processes in the selected reference areas of the Rostov region and the Krasnodar Territory of the coastal zone of the Azov Sea is carried out. A comparative assessment of the economic stability of the municipal districts of the Rostov region and the Krasnodar Territory has been carried out. The work used the software ArcGIS Pro (methods of multi-criteria spatial statistics), the DECERNS MCDA DE module (including a set of tools for multi-criteria analysis of decision-making). The study also used the ArcGIS multicriteria statistics similarity method, which relies on statistical tools to analyze the distribution of data and identify patterns (trends). The novelty of the proposed research is the application of the theory of complex risk analysis to analyze the sustainable development of the coastal zone and the choice of indicators that are key for this territory. The theoretical novelty of the research lies in the use of an interdisciplinary approach and a set of complementary methods from various sciences.

Within the northern coast of the Sea of Azov there are some accumulative forms that have similar morphological, morphodynamic and lithodynamic characteristics. These forms of the sea relief united in the group of «azov type» spits. At the present time the investigated accumulative forms develop under conditions of intense erosion. The research carried out by us for the past five years, has shown that erosion of accumulative formsʼ bodies is natural, but the building of the bank protection structures affect the lithodynamic systemʼs integrity and strengthen the process.
