The territory of the former Uranium production facility “Prydniprovsky Chemical Plant” (“PChP”) are located in Kamensky city, Dnipropetrovsk region, occupy the area of the upper and lower terraces of the Dnieper River (more than 300 hectares), where the remained legacy facilities and residues of the former uranium ore processing are located. After 1991 the production of Uranium concentrates ceased without remediated. Thus, up to 40 million tons of radioactive and chemical mineral residues of uranium production have accumulated within its industrial site and at the adjacent territories. Systemic monitoring studies began only in 2005. The studied environment characteristics were soils contamination, the tailings facilities where Uranium ore processing residues had accumulated, as well as atmospheric contamination by airborne aerosols. The purpose of this study stage is a comprehensive analysis of the spatial distribution of radionuclides of Uranium series at the legacy site territory and factors that can lead to a significant expansion of the contaminated area and scale of chronic environmental pollution under the influence of atmospheric transport and human exposure by inhalation.\u0000Data & Methods. The field sampling and analytical methods (gamma, alpha spectrometry and liquid scintillation counting methods) for determination of radionuclides of U-Th decay series were in use for this study. Soils samples from the top layers (0–5 cm) and gamma-dose rate surveys performed. A two-week continues integrated sampling data on the radioactive aerosols ambient activity concentrations and radioactive atmospheric fallout from 7-th locations at the legacy site and adjacent areas used for the environment radioactivity site-specific analyses. For determination of radionuclides in the environment samples (aerosols, soils and in the raw ore mineral residues) the low background gamma-spectrometry method with HPGe detectors have been in use. The content of metals associated with aerosols measured on filters using atomic absorption spectrometry methods. The data analysis for longterm series of observations (2005–2017) carried out using statistical methods. The compliance environment contamination analyses for the legacy site were carried comparing averaged observed data with the established safety criteria and regional background observation data.\u0000Results. The main current sources of radiation emission to the environment at the legacy site are open dispersed residues of Uranium production accumulated at the tailings facilities and at the former U‑extraction infrastructure. The spatial analyses of the gamma dose rate at the U‑production legacy site and its soil chemical contamination showed that about 30% of its territory requires decontamination. It is shown that the effects of aerosol radioactive particles dispersion from the contaminated “hot spots” at the territory such as tailings and former U‑production infrastructure are local and","PeriodicalId":398162,"journal":{"name":"Odesa National University Herald.

The issue of development of post-conflict territories and restoration of the post-conflict economy is one of the fundamental issues in international scientific research. Recently, it has also become relevant for Ukraine, which is looking for ways out and solutions to the problems of the postconflict eastern territory. The article deals with one of the possible ways to revive the post-conflict eastern territory, namely the development of Tourism.\u0000Data & Methods. The main objective of the presented study is to determine conceptual approaches to the development of post-conflict territories on the example of the revival of the tourism industry in the Luhansk and Donetsk regions of Ukraine. In order to achieve the goals and objectives of the study, general scientific and special methods of Geographical Science were used, including methods of analysis and synthesis, generalization, philosophical and dialectical.\u0000Results. Among the conceptual approaches to the development of post-conflict eastern territory are noted: the growing role of the service sector, improving the business climate and business activity; increasing the share of high-tech industrial sectors; changing behavioral stereotypes of economic entities; effective use of regional potential; development of alternative energy; environmental modernization of production and introduction of energy-saving technologies in production; large-scalegreening of the territory not only settlements, but also the adjacent steppe natural zone; carrying out restructuring works at closed coal and other industrial enterprises; reclamation of numerous waste heaps. It is proposed to step up the development of domestic tourism, taking into account these conceptual approaches. Specific proposals are presented for the possible introduction of the proposed conceptual approaches to the formation of a healthy lifestyle among the local population, as a guarantee of the development of human capital in the affected territory. The article notes that education is of great importance in this, so it is the younger generation that is emphasized. It is proved that conceptual approaches to the development of tourism in the post-conflict eastern territories will contribute to the processes of socio-economic recovery of the region, and further scientific research will contribute to the implementation of programs and strategies for post-conflict development and normalization of the situation.","PeriodicalId":398162,"journal":{"name":"Odesa National University Herald.

At present, considering the conditions of slopes equilibrium, only the stresses caused by gravity, hydrodynamic and seismic effects are most often taken into account. As for tectonic stresses, their effect on landslide slopes has hardly been studied. At the same time, landslides and deformations ofslopes in a wide spatio-temporal range (with the frequency from several months to several dozens of years and the levels of massifs tectonic discreteness from first tensof meters to first kilometres) is also recorded in fact. Empirical data indicate that wave mechanism caused by rotational regime of the Earth can be one of the possible mechanisms explaining the high-frequency quasi-cyclic spatio-temporal variability of the rock mass stress-strain state. Purpose of the work has been to identify wave deformation processes in the Earth’s upper crust according to the data of instrumentalobservation of landslide slopes and relatively long line facilities deformation regime. In this work, we also intend to substantiate the thesis that wave exotectogenesis isone of the factors reducing the overall stability of landslide slopes.\u0000Data&Methods. The data of instrumental observations of structural components deformation in the underground drainage facilities of the landslide prevention works on Odesa coast that have accumulated during 50 years of operation, as well as the results of geodetic monitoring of landslide slope and the crest of plateau on the right bank of the Malyi Adzhalyk Liman within the territory of the Port Plant (ammonium plant) in 2000–2019 have been used to study the dynamics of deformation wave processes in the Earth’s upper crust. Statistical and cartographic analyses of the data sets mentioned above were carried out according to traditional methods using the Statistica, Matlab and Surfer software packages.\u0000Results. It has been found that modern dynamics of landslide slopes is significantly influenced by the periodic change of the stress-strainstate of rocks in space and time.

At present the studying of the shores and their dynamics configuration and especially the most active parts – the heads of the Azov spits, is caused by both reasons dynamic and geopolitical changes as well. A large number of spits is a characteristic feature of the shores of the Azov Sea. There are spits all over the coast of the Azov Sea. However, spits oriented deep into the Azov Sea shore line there are just on the northern sea area. The reason of intense lithodynamic processes in the coastal zone of the Azov is the high velocities of currents in the bottom layer as a result of storm winds. In the coastal zone of the sea the cycle of abrasion rate from 1 to 4 m per year (sometimes up to 15m per year) was established. Fluctuations in the level of the Azov Sea are provides by many natural factors acting simultaneously and input to abrasion processes.

A water soil erosion is one of the most important ecological problems of the world because in the result of it the soil cover completely destroys and is not able to renew for a long time. In opinion of dr. Montgomery D., the loses of agricultural soils even limited the lifetime of ancient civilizations and the same problem closely touches today human being. Following to the information of scientists in 1970-s, about 430 million ha of lands were destroyed in different countries because of water soil erosion. Annual loses of product lands on our planet equal 5–7 million ha. In Ukraine at the end of first decade of 2000s following to National report (2010) the square of eroded agricultural lands equaled 15.954 million ha or 38.4 per cent of their common territory including 12.940 million ha of arable lands or 39.9 per cent. On average the soil loses about approximately 15 t/ha/year. Thereby the purpose of the study is a spatial distributed quantitative assessment of the intensity of erosion soil loses in the right-bank forest-steppe zone of Ukraine and definition of arable squares with different rates of erosion load considering present climate changes and land use peculiarities.\u0000Data &Methods. For the estimation of average soil wash off three typical slope plots (К1-р, К2-р, К3-р) were used. The plots are situated within the territory of Educational and Scientific Stationary of the Odesa I. I. Mechnikov National University that is in Podilsk district of the north part of Odesa region. This territory is on south hills of Podolska upland in forest-steppe zone. The plots are the different parts of small valleys slopes which are annual plowed up and used for growing of the most profit-making crops – wheat, corn, barley and sunflower. No any scientifically based crop rotation uses there at least for the last twenty years. The spatial distributed physical and statistical model of soil wash off and accumulation was used as a working model for the estimation of average annual soil loses consideringthe peculiarities of land cultivation and anti-erosion crops properties.

Tiligulskyi liman is located in the northwestern part of the Black Sea between the Odessa bay and the Berezansky liman. Operation and reconstruction of the connecting channel influence the geosystem of the estuarine part of the Tiligulskyi liman. Now the channel operates not reinforced and its relief changes dynamically influenced by the combination of natural and anthropogenic factors. Monitoring changes will make it possible to predict how the anthropogenic factors impact to reserved coastal landscapes. The main goal of the research – to find out morphological and morphometric characteristics of the relief’s current state and to define granulometric composition of sediments of the connecting channel Tiligulskyi liman – Black Sea in conditions of artificial regulation of water exchange. Data & Methods. Field studies were carried out at the Tiligulskyi liman sand bar on 5 areas in 2020 and 2021. Performed: depth measurements, GPS coastline mapping, water and sediment sampling. Based on the field studies results the following was determined: В – width, F – cross-sectional area, Нmax – maximum depth, Нavg – average depth, χ- wetted perimeter. Fifteen sediment samples were taken from the elements of the channel’s relief. Granulometric coefficients are determined by the graphical method of PD Trask and by statistical methods. Results. Functioning unforced connecting channel Tiligulskiy liman – Black Sea in conditions of artificial regulations of water consumption, periodical admission of sediment from liman and sea areas against the background of hydrometeorological factors leads to significant linear and vertical deformations of the canal relief. Because of it’s significant length morphological processes are different at each location. Morphological characteristics of connecting channel Tiligulskyi liman – Black sea is highly different in depends of water level. When water level rises on 0.6 m – B, Havg, χ gets higher twice, Hmax – 4 times, and F – 5 times. Current sediments of connecting channel presented as small sand particles and fine to medium sandy granulometric varieties. Prevalent fraction size in all samples is 0.1–0.25 mm. Calculated by V. N. Goncharov’s formula non-blurring sediment speed increases from 0.26 m/s (at canal depths 0.2) to 0.41 m/s (at canal depths 2.0 m), that leads to significant relief deformation during its operation.

A common feature of all parameters in the interannual variability, is the presence of well-defined wave fluctuations of different scales which occurs against the background of alternating trends. The connection with the El Niño phenomenon is one of the reasons for the observed surges in changes in the water and air environments in the Black Sea region. The level fluctuations in the Black Sea are synchronous on low-frequency scales (their period is more than 5 years) because they are under the influence of global climate processes on our planet.

In their development, they experienced significant changes along with changes of the bay-bar caused by the channel connecting the Black Sea with the Tyligulskyi Liman, individual lakes to an artificial channel. According to the genesis of the lake basin are presented on the bar the remaining coastal lakes, anthropogenic and anthropogenic-transformed. At the present stage, the water bodies’ development is determined by operation frequency of the artificial connecting channel, level fluctuations, up and down surges. The inflow of estuary water into the water bodies of the bay-bar is constant at all stages of their development, in contrast to its inflow from the sea. On the Tyligulskyi liman bay-bar, there are constantly three water bodies: the northern lake, a chain of central and eastern lakes, and the channel. Commissioning of the channel connecting the Black Sea with the Tyligulskyi liman has led to an increase in the total lake percentage of the bay-bar from 3.9–11.1% in its natural state to 20.4–26.5% at present. With all its insignificant parameters, the connecting channel performs a system-forming function – it provides water exchange and the functioning of the natural complexes of the inner part of the Tiligul bay-bar.
