Geomorphological Survey

In the coastal zone of the oceans, there are various coastal systems, among which the most specific are “winged forelands”. Within the Black Sea coast there are four “winged forelands”: Tendra–Dzharylgach, Kinburnska–Pokrovska–Dovgiy, Burnaska–Budatska and Lebedyna–Ustrychna, which named by same structural ones. The purpose of the publication is to systematize the primary information about the morphological features of the coastal zone of the barrier system type ‘winged foreland” Kinburnska–Pokrovska–Dovgy which was obtained during field research.During the natural research in 2019, within the most typical areas of the coastal zone, reference benchmarks and morphological profiles were laid and recorded by a GPS. The total length of the coastal system is about 35 km, within its boundaries there are 7 benchmarks, which contains for 1 benchmark per 5 km, and a systematic geomorphological survey of 20 profiles (1 profile per 1.75 km) is carried out. Relevant indicators suggest that the results of the research are reliable.Morphologically, the studied system is a “winged foreland”, within which there are four structural and morphological elements: Kinburnska Spit, Frontal Coast or “headland”, Pokrovska Spit with the islands of Kruglyi and Dovhyi. Kinburnska Spit is a free accumulative coastal form located in the northwestern part of the Kinburn Peninsula. Morphogenetically, it is an arrow that develops in the conditions of bilateral feeding by beach sediments. The Frontal Coast or “headland” is the central component, within which the sand massifs of the Kinburn Peninsula go directly to the coastal zone. Pokrovska spit with the islands of Krugliy and Dovhiy is a relict generation, which is genetically an ancient accumulative form divided into three components. All these components are located on the surface of the base of the ancient coastal form, and their development occurs in conditions of limited supply of beach sediments. The front of the Pokrovsky Peninsula with the Sukha Spit and the Island Bar “Zagreba” is a modern accumulative generation that is actively increasing in size and advancing towards the waters of Tendra Bay.Key words: coastal systems, “winged foreland”, coastal zone, underwater slope, shore, coastal systems, foredunes У береговій зоні Світового океану існують різноманітні берегові системи, серед яких найбільш специфічні «крилаті миси». У межах узбережжя Чорного моря виділяються чотири «крилаті миси»: Тендра–Джарилгач, Кінбурнська–Покровська–Довгий, Бурнаська–Будацька та Лебедина–Устрична. Мета публікації полягає у систематизації та оприлюдненні первинної інформації про морфологічні особливості берегової зони бар’єрної системи типу «крилатий мис» Кінбурнська–Покровська–Довгий, отриманої під час польових досліджень 2018–2021 рр. Загальна довжина дослідженої берегової системи близько 35 км, в її межах закладено 7 репер-них стаціонарних ділянок та проводиться систематична геоморфологічна зйомка на 20 профілях, положення яких зафіксовано за допомогою GPS-приймача. Розроблена система стаціонарних ділянок і геоморфологічних профілів дозволяє надійно проводити довготермінові спостереження в масштабі 1:10000. Відповідні показники дозволяють вважати, що результати проведених досліджень є достовірними.У морфологічному відношенні досліджувана система є «крилатим мисом», в її межах виділяються чотири структурно-морфологічні елементи: Кінбурнська коса, Фронтальний берег, Покровська коса з островами Круглий та Довгий, Фронт Покровського півострова із Сухою косою та острівним баром «Загреба».Кінбурнська коса – це вільна акумулятивна берегова форма, розташована у північно-західній частині Кінбурнського півострова. В морфогенетичному відношенні це стрілка, яка розвивається в умовах двостороннього живлення прибережно-морськими наносами. Фронтальний берег, або «лобище», є центральним складовим елементом, у межах якого безпосередньо до берегової зони виходять піщані масиви Кінбурнського півострова. Покровська коса з островами Круглий та Довгий є реліктовою генерацією, яка в генетичному відношенні є давньою акумулятивною формою, поділеною на три складники. Всі перелічені складники розташовані на поверхні цоколю давньої берегової форми, а їх розвиток відбувається в умовах обмеженого живлення прибережно-морськими наносами. Фронт Покровського півострова із Сухою косою та острівним баром «Загреба» являє собою нову акумулятивну генерацію, яка активно збільшується у розмірах та висувається в бік акваторії заток.Ключові слова: берегові системи, «крилатий мис», підводний схил, берег, підводний вал, авандюна.

The aim of our investigation is a survey of heavy metal pollution in algae, sediments and water from the Bulgarian Black Sea coast and determination of algae species appropriate as bioindicators. The levels of iron, copper, manganese, zinc, lead and cadmium are determined in water, sediments and eight species of macroalgae: (four green: Cladofora laetevirens, Ulva rigida, Enteromorpha intestinalis and Bryopsis plumosa; two brown: Cystoseira crinita and Cystoseira barbata; and two red: Ceramium rubrum and Corallina mediterranium), widely distributed in the Bulgarian coastal zone, and dominant in the Black Sea. The studied area is the littoral coastal zone from four locations - Tuzlata, Ravda, Ahtopol and Sinemoretz. No significant variations between metal concentrations in algae samples are obtained, while for sediments and water there are significant differences between location and season. The Cladofora laetevirens and Ceramium rubrum species show the highest metal content while Cystoseira crinita and Cystoseira barbata show the lowest level. The correlation coefficients and concentration factors of the elements are calculated.

Purpose. The goal of the study is estimation the scale of the plastic waste’s area in the coastal zone of the Northwestern part of the Black Sea and their role of the of polution formation. Methods. The base of methods is system analyses. Results. The annual volume of solid waste in the North-Western Black Sea region can reach 2.5 million tons per year, and the volume of plastic littre - up to 323 thousand tons per year. In spite of of plastic littre as the resource, at present there is no definite system for handling them, and under these conditions they are disposed of at numerous dumps (including unauthorized ones) of solid household waste. A significant part of plastic (up to 80%) from unorganized landfills and from the other coastal pollution sources is carried out by air and water flows in the water area of the Northwestern part of the Black Sea. Approximatly 83% of marine littre in the Black Sea is plastic. In turn, the presence of marine littre links with the imperfection of the solid waste management system. The dominant way of manage is remains their removal and disposal in landfills. As of 2019, in the Odessa region there were 528 landfills, in the Nikolaev region - 267, in the Kherson region - 54. Almost 17% of landfills in the Odessa region and 26% in the Nikolaev region do not comply according to environmental hazard standards. Significant part of the plastic littre, first of all from unauthorized of the solid waste dumps, is carried by air flows into the river network, and if they are close to the beach area, directly into the Black Sea. Plastic littre is carried out from the catchment areas of the large rivers (Danube, Dniester, Southern Bug and Dnieper), as well as water intakes of numerous medium and small rivers. Almost the whole beach area of the Northwestern part of the Black Sea is actively used for recreational purposes and, therefore, is a source of beach waste. In addition, the coastal sources of garbage can be settlements, marine complexes and agricultural lands located along the coastal line. An insignificant share of plastic littre is generated within the sea area (from shipping, fishing, etc.). Conclusions. The main component of marine littre is plastic, as it accounts for 83% of marine littre founded in the Black Sea. Macroplastics can be subject to long-term movement by the sea currents, winds, waves and poses a direct threat to the marine ecosystem. Directions of movement of marine littre depends on the processes of general circulation in the surface layer (0-500 m) of the Black Sea. The processes of biodegradation of macroplastic are hindered in the marine environment, and therefore its transformation is limited by the processes of destruction and dispersion in micro- and nanoparticles. Taking into consideration the environmental hazard of microplastics, it is advisable to create a system for monitoring in the marine environment. To improve the environmental situation in the coastal zone of the Northwestern part of the Black Sea, it is necessary to significantly increase the volume of recycled plastic littre, as well as to eliminate numerous landfills for solid household waste that do not accord to environmental safety requirements.

Heavy Rains

Heavy rains have become a serious problem for the coastal zone of the Krasnodar Territory of the Russian Federation and the Black Sea coast of Turkey. They lead to a significant increase in water levels in rivers, flooding of villages and even large cities, damage to urban and tourist infrastructure, roads and railways, bridges, beaches, flushing of garbage and sewage into rivers. This leads to environmental problems and even loss of life. River runoff forms river plumes in the coastal zone of the sea, which, depending on wind speed and direction, speed and direction of coastal currents, river runoff and density difference with sea water, can have various forms and spread in different directions from the mouth of the river, as well as participate in mesoscale and sub-mesoscale circulation of coastal waters. River plumes significantly affect the quality of sea water and the sanitary and epidemiological situation on the beaches of the resort area of Krasnodar Territory and Turkey. The situation is aggravated by the fact that sewage systems are in poor condition in cities or are completely absent in most of small villages along rivers and the coastal zone. After heavy rains, wastewater very often reaches the sea and poses a serious threat to human health. The purpose of this study is to use satellite remote sensing to demonstrate the behavior of river plumes along the Black Sea Turkish coast.

<p>Over the last two decades, in line with the global trend of expanding research into natural hazards and disaster risk reduction, the tsunami hazard and risk assessment along the coast of Europe has become a hot topic of research. In all its aspects, tsunami research includes the study of tsunami documentary evidence, historical data collection, field experiments, laboratory research, theoretical numerical and analytical modelling, and in-depth analysis of recent tsunami events. Tsunami modelling research methodologies and holistic approaches to risk assessment are continually being improved. Researches are directed to develop conventional standardised methods to analyse tsunami hazard and risk with associated uncertainties, aiming to reduce possible adverse effects on potentially vulnerable coastal settlements, coastal and marine infrastructures and natural ecosystems.</p><p>In the Black Sea, dangerous tsunami waves are a relatively rare phenomenon that cannot be forecast. Multidisciplinary studies focused on mapping and dating past events on the Black Sea coast, determining the causes, frequency of recurrence, and current prospects for tsunamis occurrence (risk) are not yet fully clarified or are in their infancy. Moreover, tsunami hazard along the Bulgarian coast is poorly understood and not considered in the National methodology for flood hazards and risk in the coastal zone. Numerical tsunami modelling performed in recent years for the region still needs to be improved. These events are relatively rare, few such cases have been documented, and validation data are scarce or missing.</p><p>This study provides a comprehensive inventory of tsunami sources from scientific publications, model studies of tsunami generated waves carried out during the recent years and an analysis of the results from recently established early warning systems in the Black Sea region. For the Bulgarian coastal zone, the results of studies of active faults with tsunamigenic potential in and around vulnerable coastal zones, available registrations at sea level during seismic events and some extreme meteorological events for the last century are summarized. A near-field and far-field tsunami sources that can generate tsunamis and affect the Bulgarian coastline are briefly reviewed. High-resolution data are needed for more credible tsunami numerical modelling for the western Black Sea region. Preliminary studies of the available datasets regarding Digital Elevation Model (DEM) and bathymetry for specific locations along the coastal zone are presented as well the needed accuracy and completeness of the data. Some consideration regarding the available and newly establish research infrastructure in the western Black Sea are also discussed.</p><p><strong>Acknowledgements:</strong><strong> </strong>The authors would like to thank the Bulgarian National Science Fund for co-funding the research under the Contract КП-СЕ-КОСТ/8, 25.09.2020, which is carried out within the framework of COST Action 18109 “Accelerating Global science In Tsunami HAzard and Risk analysis” (AGITHAR; https://www.agithar.uni-hamburg.de/).</p>

Abrasion coasts (cliffs) are characterized by heterogeneity of the spatial structure and mobility of the substrate, which creates specific environmental conditions for plants. Nevertheless, plant communities of cliffs of the Black Sea coast of the Northwestern Caucasus are well developed due to the presence of a large number of Mediterranean species that are well adapted to such conditions. Communities are also supplemented by local endemics and representatives of petrophytic vegetation of adjacent areas. As a result, a specific plant community is formed on the cliff, represented by species from different floristic areas. Thus, the aim of this work was to analyze the species composition of higher vascular plants of the abrasion shore area of the Black Sea coast of the Northwestern Caucasus. On the studied cliff, 131 species of vascular plants were found, including 5 Crimean-Novorossiysk and 6 Novorossiysk endemic, as well as 6 species found in the Red List of the Russian Federation. Extreme unevenness in the density distribution of vegetation was noted, which may be due to the heterogeneity of the relief and the mobility of the substrate. Analysis of supraspecific taxa (families) showed the predominance of representatives of the Apiaceae, Fabaceae, and Poaceae families in the plant community. In addition, chorological analysis of vascular plant species was performed. The data of the performed chorological analysis confirm the relation of the studied territory to the Crimean Novorossiysk province. Thus, despite the specific environmental conditions, the plant community of the studied cliff is rich in species, including endemic species.

The Southern coast of Crimea (SCC) forms a separate physical and geographical area located in the extreme South of the Crimean Peninsula, between the Main range of the Crimean Mountains and the Black Sea coast. Currently, the coast of the SCC is mostly concreted (65%). Therefore, fragments of the coastal zone with preserved natural vegetation have a special environmental value, one of such sites is the Kuchuk-Lambatsky stone chaos. Kuchuk-Lambatsky stone chaos is a Specially Protected Natural Area (SPNA), but the coastal-marine area does not have any protected status. In the coastal zone of the sea, it is very important that protected areas include both land areas and coastal–marine areas. Information about the species composition and the structure of phytobenthos of the supra – and pseudolittoral zones in the marine area of the Kuchuk-Lambatsky stone chaos is presented. In total 43 species of phytobenthos have been identified: Rhodophyta – 10 species, Chlorophyta – 7, Ochrophyta – 3, Cyanobacteria – 23. Altogether 23 species were found in the supralitoral zone. During the observation period, the vegetation cover of the supralittoral zone was formed exclusively by Cyanobacteria, represented by one class, 5 orders, 10 families and 15 genera. The community, dominated by Calothrix scopulorum, Gloeocapsopsis crepidinum and Aphanocapsa incerta was found. The community is mainly formed by typical benthic, marine, and cosmopolitan species. In total 20 species of macrophyte algae were observed in the pseudolittoral zone. The Rhodophyta division is represented by one class, 5 orders, 6 families, and 8 genera. The Ochrophyta division has one class, 2 orders, 3 families, and 3 genera. The division Chlorophyta is represented by one class, 2 orders, 3 families, and 4 genera. In the pseudolittoral zone the community dominated by Ulva kylinii and U. intestinalis has been registered. It is formed mainly by annual, marine and brackish-marine, mesosaprobic species.

Tourist Flow

Among all the natural resources available in Odesa Region vacationists prefer beaches and associated entertainments. Quality and general ecological condition of the beaches in addition to the potential and actual beach capacity are key factors for tourist flow to Odesa Region and its socio-economic development. In order to substantiate the recreational and tourist development of the territory an economic and logistic evaluation of its resource base should be carried out. This will make it possible to determine an input tourist flow which dictates the volumes of required tourist infrastructure and material and technical facilities. The purpose of this study is to evaluate recreational potential of Odesa Region’s beach zones. To achieve this, all main natural and anthropogenic factors determining the recreational potential of the coastal zone were analyzed. The study is also based on scientific researches in the field of recreational and tourist activities made by well-known experts, on the existing regulatory frameworks and results of the authors' own research works. For the first time, recreational capacity and logistic potential of Odesa Region’s beach zones were estimated. Based on this estimation multiple conclusions about the most promising areas for future development of the recreation sector were made. It was determined that favorable climatic conditions, considerable length of beaches and other natural and recreational resources allow us to speak about good prospects of the Odesa Region’s coastal zone for various forms of recreation including thalassotherapy. In fact, thalassotherapy opportunity (first of all, beach recreation) is a very important factor of attractiveness for vacationists visiting the Odesa Region’s coastal zone. According to our research, Bilhorod-Dnistrovskyi, Tatarbunarskyi and Lymanskyi districts are the most promising ones for recreational development. The total capacity of the beaches here even exceeds the districts' own population. Conducted recreational zoning of the Odesa’s Black Sea coast established that, based on the natural recreational factors, out of 9 recreational microdistricts only 3 of them may be classified as favorable, with 5 being relatively favorable and 1 – completely unfavorable. But, from the perspective of sea water quality, some microdistricts (Luzanivskyi and Arkadiyskyi) do not meet sanitary standards during the period of intense precipitation. It was found that there is a need for expansion of beach areas as well as a need for regulation and redistribution of the recreational and tourist flow. In order to increase recreational attractiveness of Odesa Region, regional and city administrations should pay more attention to the ecological conditions of beach areas of the Black Sea coast. The obtained results may be used by the Department of Culture and Tourism of the Odesa Regional State Administration, divisions of the Ministry of Ecology and Natural Resources of Ukraine in order to assess the recreational potential of the Odesa Region’s beach areas.
