Abstract
The purpose of this work is to comprehensively study the ecological and geological conditions and the results of monitoring studies of the coastal territories of the Taganrog Bay and the Sea of Azov to identify the degree of manifestation of dangerous coastal processes (DCP). The subject of the study is to assess the degree of manifestation of DCP under the influence of various natural factors, both constant in time (geological structure, height of the coastal cliff), and changing (dynamics of the level, waves, wind regime) and the impact of man-made causes. The performed factor analysis allows us to assert that the main natural factor of the intensification of DCP is the extreme surge levels (adverse end dangerous events: AE and DE). The types of shores are constant, but with different degrees of manifestation of DCP, they change significantly. As a result, according to these studies, maps were constructed for the average long-term (1980), intensive manifestation (2013–2014) and the period with a relatively calm manifestation of the intensity of DCP (2018–2020). According to the activity, the manifestations of DCP are divided into 4 types: type I – with a very high c (>4 m/year), type II – with a high (2–4 m/year), type III – with an average (1–2 m/year), type IV – with a weak rate (<1 m/year) of abrasions, which include subtypes of banks formed by exogenous processes (abrasive, abrasive-landslide, accumulative), indicating the conditions of their formation and the reasons for the isolation of the danger of coastal processes.
