Geoinformation modeling of irradiation dose formaion for rural population of Narodychy district of Zhytomyr region
Authors V. Dolin, D. Khrushchov, T. Magliovana, V. Vasylenko, D. Matrosov and D. BaranovskaSummaryAccording to the density of cesium-137 contamination after the Chornobyl catastrophe, the study area belongs to the abandoned zone (zone of unconditional mandatory resettlement). The population is about 10,000 inhabitants. The spatio-temporal regularities of the passport radiation dose change of Narodytsky district of Zhytomyr region rural population are parameterized. The dynamics of the formation of the annual passport irradiation dose is subjected to two-exponential dependence. The “fast” (first 2–3 years after the accident) and “slow” (next 10–15 years) components of the passport dose formation were distinguished. The parameters of the irradiation dose evolution are analyzed from the standpoint of the theory of infogeoframes. Maps of spatial distribution of certain parameters in the ArcGIS medium are constructed. By combining infogeoframes of different semantic load (pollution density, landscape-geochemical conditions, soil type, parameters of dose loading evolution) and pixelization of the same scale, a map of the modern radioecological state of the district was created. Areas of stable radioecological situation (possible recreation), unstable radioecological situation (compulsory rehabilitation), dangerous radioecological situation (activity prohibited), and long-term alienation are outlined.

Mapping the accessibility to terrestrial natural and cultural areas in Lithuania
Authors M. Inácio, E. Gomes, K. Bogdzevič, D. Karnauskaitė, M. Kalinauskas and P. PereiraSummaryMapping the accessibility to terrestrial natural and cultural areas is key to understanding an urban area’s potential to offer multiple ecosystem services. In this work, we aim to study the accessibility of Lithuanian inhabited areas (9088) to natural and cultural areas. A framework was developed based on the accessibility to water bodies, protected areas, and heritage sites. The results showed that most inhabited areas have good and very good access to natural and cultural sites. However, some areas with reduced accessibility may need some recuperation to increase the population well-being of these areas.

Use of GIS for determining mountain local obstacles of routes in low mountains
Authors N. Korohoda, O. Kovtoniuk, T. Kupach and N. PohorilchukSummaryRoutes of field student professional-oriented practice were developed to the territory of the Privododilni Gorgany and Svydovets ridges (Ukrainian Carpathians). Length, duration, presence of mountain local obstacles (MLO) cause different difficulty levels of these routes passage. The researching goal is to identify MLO and determine the difficulty level of the routes. The most successful way to obtain information about the mountain local obstacles is a profiling and morphometric analysis of the routes. We used to cartometric and morphometric analysis of this study standard tools of ArcGIS modules. It allowed to select mountain local obstacles, which corresponds to the difficulty category 1a, on 4 of the 6 analyzed graphs of routes longitudinal profiles. Identified MLO will allow to include these routes in the network of categorical routes of sports tourism in the region.

Anomalous groundwater-rocks interactions for conditions of the Cenomanian-Callovian aquifer exploited by the Obolon water intake wells in Kyiv
Authors I. Koliabina, V. Shestopalov and N. KasteltsevaSummaryThe purpose of this work is to estimate interactions in the water-rock system using an integrated approach, which includes the balance method and the method of geochemical (thermodynamic) modelling, and to illuminate the role of these interactions in the formation of water composition of the Cenomanian-Callovian aquifer. The results show the differences both in water composition and mechanisms of its formation within the small area of the Obolon water intake wells location. Two groups were conventionally distinguished. In water of the Icen group the Cl- specific content is almost two times higher than in water of the IIcen group. In water, classified as group Icen, the role of ion exchange processes is insignificant. The specific feature of water classified as group IIcen is the imbalance exists between sodium and chlorine concentrations. With increase of Cl- concentration sodium concentration remains unchanged and varies around the average value. Formation of the chemical composition of water of the group IIcen can be described as follows: first, groundwater balanced by sodium and chlorine enters the aquifer, then, as a result of ionic exchange and precipitation of montmorillonite and illite, sodium is removed from the water, while the concentration of chlorine doesn’t change.

Modeling of the hydrodynamic conditions of Lake Sasyk according to granulometric analysis
Authors M. D. Krochak, V. O. Yemelianov, Y. I. Voropai, V. I. Holoborodko and A.Sh. MienasovaSummaryThe aim of the work is to study the structure of sediments of Lake Sasyk (northwest coast of the Black Sea) and the nature of their distribution in the lake. The work was performed on the basis of granulometric analysis of bottom silt samples performed in the Laboratory of Physical Research Methods of the Institute of Geological Sciences of the National Academy of Sciences of Ukraine. To visualize the tabular data of the obtained results we performed their mathematical processing in the program of graphical constructions Surfer, schemes of distribution of various fractions on the area of lake are created. It is concluded that the sediments of Lake Sasyk are represented by siltstone clays and clay siltstones. The saturation of sediment with clastic fraction decreases in the direction of the central parts of the reservoir, which is typical for lake-type pools. This pattern is violated in the southwestern part of the lake at the confluence of fresh waters of the Danube-Sasyk canal. The current erodes the coastal siltstone deposits at the confluence and brings additional suspended pelitic material to the lake. This leads to stable siltation of sediments.

Geoecological atlas of the nature reserve fund of Ukraine as a geoinformation system: a methodological approach to content development
Authors E. Bondarenko and M. KyryliukSummaryThe publication presents a methodological approach to creating a geo-ecological Atlas of the nature reserve fund of Ukraine. It is defined as a modern specialized atlas electronic cartographic work and a cartographic service of wide application. It is implemented through geographic information systems (GIS) and acts as such a system.
The general structure is substantiated, which has three parts (introductory, substantive, additional), purpose and composition of each of them.
It is proved that the development of the content of the geoecological Atlas of the Nature Reserve Fund of Ukraine as a computer GIS makes it possible to minimize the existing individual contradictions to ensure its internal unity through the use of existing functionality of relevant software products.
The functions of the content part and the Atlas as a whole (informative, evaluative, methodical, methodological, organizing) are determined; criteria of value and fundamentality.
Methodological principles of formation of the substantive part of the geoecological atlas of the NRF of Ukraine on the possible presentation of various thematic maps in it are formulated: consistently traditional; block-problematic; combined. The latter principle is the most optimal for use in this cartographic work.

GIS in landscape architecture and design
Authors L. Bilous, V. Samoilenko, P. Shyshchenko and O. HavrylenkoSummaryThe necessity of introduction of methods of the geoinformation analysis of territories to decision-making systems in landscape-architectural and landscape-design activity is substantiated.
The key role of GIS in the procedure of creating landscape projects and plans in connection with the European Landscape Convention is identified.
There is a need to integrate GIS software with special tools for landscape designers and architects, namely: AutoCAD, Google SketchUp, RealTime Landscaping Architect, etc. It is dictated, in particular, by the priority of substantiation of ecological decisions at creation of plans and projects of the organization of landscape spaces of home gardens, cities, regions.
Educational space and the state of the national spatial data infrastructure are considered as determining factors in the perception and use of GIS by landscape architects and designers in Ukraine.
GIS is considered as a spatial environment for the synthesis of natural science intelligence for landscape architecture and design. In particular, GIS is defined as a tool for finding the parametric location of territories (morphometric, hydrological, lithological, soil, biocoenosis, process, etc.) in the geographical diversity of landscapes. The information potential of GIS application in the organization of public spaces is outlined in connection with the spatial analysis of the Digital Elevation Model.

Structure design of the drought risk assessment and mapping technology for adaptation of Ukrainian water sector to climate change
Authors S. Snizhko, G. Trypolska, O. Shevchenko, V. Grebin and I. KostyrkoSummaryThis paper suggests a structure design of drought risk assessment and mapping technology and a 6-stage implementation process regarding the country specifics of Ukraine.
“Stage-to-stage” implementation process involves collection of observational data for drought assessment (both field measurements and satellite data), data pre-processing, formulation of methodology for drought assessment, assessment of drought and mapping. The final stage of technology seeks next technical procedure with DI spatial database like spatial DI interpolation, visualizing resulting DI maps, publicly available DI maps publication. The creation of risk maps requires Geographical Information Systems (GIS) software. To carry out it, the spatial data analysis can be used for next GIS software: MapInfo, ERDAS, Intergraph, IDRISI, GRAM, ArcInfo, GRASS, AutoCAD maps etc. For the mapping of drought, the most widely used ArcGIS in Ukraine, developed by the Institute for Environmental Systems Research (ESRI), can be recommended. ArcGIS offers a unique set of capabilities for applying location-based analytics to drought mapping, contextual tools to visualize and analyse ground based and satellite data. It includes imagery tools and workflows for visualization and analysis, and access to the world’s largest imagery collection.

Experience in determining transboundary interaction of groundwater bodies (on the example of Ukraine and Belarus)
More LessSummaryThe «European Union Water Initiative Plus for Eastern Partnership Countries (EUWI+)» project addresses existing challenges in implementation of efficient management of water resources and in particular the water monitoring capacities. A recent study of 2019 identified eight groundwater bodies (GWB) in the Dnipro River Basin of Ukraine which are transboundary linked with six corresponding GWBs in the Pripyat and Dnieper River Basins of the Republic of Belarus. As some of GWBs are considerably large, the next research has focused on identifying those sub-parts of the GWBs in Ukraine which are subject to transboundary groundwater interaction. It was established that conditions for groundwater resources formation in the transboundary Ukraine-Belarusian zone in the Dnipro basin are very favorable, because groundwater recharge occurs on the territory of Ukraine, where the territory is sparsely populated and human pressure is minimal. The impact from dispersed small water users that extract groundwater in transboundary zone is negligible. So, both the quantitative and the qualitative status of the GWBs in the transboundary area are predominantly good. At the same time, there are common problems to be solved which require groundwater monitoring restoration and its coordination with the Belarusian side.

A framework of tectonic lineaments of the Black Sea region and surrounding areas of the Mediterranean Mobile Belt
Authors V. V. Pokalyuk, I. E. Lomakin, V. G. Verkhovtsev and V. V. KochelabSummaryA close correspondence has been established between different-ranked tectonic lineamentous structural plans: the Black Sea basin/region, on the one hand, and the Mediterranean mobile belt as a whole, on the other. This indicates the coherency of faults and fault zones within the entire Mediterranean – both within the sea areas and the continental surroundingds. The structural position of the Black Sea basin as a whole is determined by its location at the intersection area (superposition, interference) of the diagonal (subdiagonal) transcontinental tectonic lineamentous belts: the north-west – Baltic-Iranian (Elba-Zagros), Caucasus-Kopetdag, and the north-east – Atlas- Black Sea. The absence of large-scale lateral displacements at the intersection nodes of differently oriented supermegalineament systems indicates the relative autonomous stationarity and inheritance of the formation of the lyneament framework during the entire Mezozoic-Cenozoic and relatively low-shear nature of its realization. This feature of the Black Sea region structural pattern significantly limits the possibility of using neomobilistic geodynamic models to explain the history of the geological development of the region. The strict consistency and orderliness of the lineament framework can be ensured only by global planetary factors associated with the influence of the rotational regime of the Earth’s shells on the stress distribution in the lithosphere.

Modelling of environmental objects geochemical transformation within solid waste landfills
Authors I. V. Kuraieva, T. O. Koshliakova, O. T. Azimov, K. S. Zlobina and D. P. KhrushchovSummaryThe purpose of the research was to study geochemical transformation of environmental objects (soils, surface and ground water) within the one of the largest landfills in Ukraine for solid waste disposal – Kyiv landfill №5. During the research such laboratory methods were used: atomic absorption method, emission spectral analysis, and inductively coupled plasma mass spectrometry. Physical-chemical features of soils were determined by chemical and potentiometric methods, and finding forms of heavy metals in soils were defined by stepwise extraction method. Migration forms of micro- and macroelements with organic and mineral components of soil solutions were determined by methods of mathematical modelling using specialized software MINTEQA 2. For mathematical processing of the obtained results such methods were used as statistical and regression analysis. As a result of the study, specific features of physical-chemical properties of soil sediments within the landfill were revealed – high sorption capacity and low buffer ratio, which causes weak protective properties against technogenic metals. Such properties of studied soils contribute to the formation of toxic elements mobile forms and their migration to groundwater. During the study of ground and surface water samples significant deviation from the norm was found (some elements concentrations exceed MPC in dozens of times).

T. Binnert Heites rule of perspective geological correlation as a tool for solving geological problems
Authors O. Karpenko and M. MyrontsovSummaryCanadian geologist T. Binner Heites in 1963 in his article set out his vision of geometric patterns that are the result of geological processes during the formation of sedimentary rocks in space (T. Heites’ hypothesis or rule). The rule states that at two points on the surface of the studying area, the ratio of sediment accumulation velocities remains stable within the age borders of a stable tectonic regime. According to this rule of Geological perspective correlation by T. Heites with the use of well-logging diagrams, it is possible to detect in hydrocarbon deposits the intervals of the section with a stable paleotectonic regime of sediment accumulation and the limits of paleotectonic regime change. Practical examples show the effectiveness of the Heites rule for the detection of promising strata or horizons in the sections of gas fields in the Outer zone of the Precarpathian Depression. Also, using the gradient of the ratios of accumulated thicknesses in different wells, it was shown that it is possible to distinguish in geological sections the age intervals with different intensity of tectonic regime - on the example of the Yablunivske oil and gas condensate field.

Soil mineral magnetism of the Rubaniv gas field (Carpathian Foredeep, Ukraine)
Authors O. Menshov, R. Kuderavets, I. Chobotok and N. PyrizhokSummaryMagnetic method is effective, rapid, and cheap technology in the geophysical studying of hydrocarbon fields. The present study related to the investigation of the Rubaniv gas field in the Outer zone of the Carpathian Foredeep. Our previous results demonstrated the close dependence of the local anomalous magnetic field upon gas deposit of Rubaniv field, soil magnetic susceptibility of the genetic horizons, and possible gas microseepage. New results are concentrated in magnetic mineralogy of soils from the areas of hydrocarbons impact as well as natural patches. The genesis of soil mineral magnetism deals with iron oxides, hydroxides, and sulphides. We identified natural magnetite, hematite, goethite, maghemite and paramagnetics formation in both soils from the hydrocarbon impacted areas as well as from the natural forest area. The hydrocarbon genesis of the soil magnetics within oil and gas fields suggested by the presence of iron sulphides, oxidation of pyrite, transformation of the antiferromagnetic hexagonal pyrrhotite into ferromagnetic monoclinic pyrrhotite.

Structure design of the flood hazard assessment and mapping technology for adaptation of Ukrainian water sector to climate change
Authors S. Snizhko, G. Trypolska, O. Shevchenko, O. Obodovskyi, I. Didovets and I. KostyrkoSummaryIn the last 20 years, Ukraine has experienced significant floods that have led to emergencies. Recent research suggests that under the influence of climate change, the recurrence of high floods in Ukraine and their magnitude will increase by the end of this century.
One of the modern technologies of adaptation to extreme manifestations of climate change in the water sector is technology of flood hazard assessment and mapping. Its use can help prevent and reduce losses in the Ukrainian economy. The technology flood’s hazard assessment and mapping are used to identify areas at the risk of flooding, and consequently to improve flood’s risk management and disaster preparedness. Flood hazard assessments and maps typically look at the expected extent and depth of flooding in a given location, on the basis of various scenarios.
This paper presents the structure and content of this technology designed by us and adapted to modern remote methods of environmental research and geographic information technologies.
