Use of unmanned aerial systems for assessing the dynamics of hazardous engineering and geocryological processes on linear facilities

Linear engineering facilities, such as gas transportation systems, extend from 30 to 500 metres in width and several hundred kilometres in length. Such routes pass through areas characterized by sufficiently diverse engineering, geological, geocryological and seismotectonic conditions. The safe and reliable functioning of gas transportation systems is ensured by their regular monitoring to prevent the development of hazardous exogenous geological processes. In particular, when monitoring ice formation, the greatest efficiency can be achieved by using unmanned aerial vehicles for low-altitude aerial surveys. In this research, remote sensing methods based on unmanned technologies were applied to assess the aufeis hazard in a section of the Power of Siberia gas pipeline in South Yakutia. The authors’ successful experience of using unmanned systems during an aeromagnetic exploration of iron ore deposits in South Yakutia was also considered. A series of studies, including georadar and electrical exploration profiling, as well as thermal imaging and high-resolution aerial photography by an aerial complex, was conducted to assess the dynamics of ice development over time in the area under study and to establish the signs of a developing hazardous process.

Yilan crater, a newly identified impact structure in northeast China

This study reports the discovery of Yilan crater, a newly identified impact structure in northeast China. The crater has a rim-to-rim diameter of 1.85 km, and is located in Yilan County of Heilongjiang Province. The latitude and longitude coordinates of the crater are 46°23′03″N and 129°18′40″E, respectively. The crater lies in a low mountainous and hilly area of the southwest border of the Xiaoxinganling mountain range. Most of the crater is covered with dense forests. Geotectonically, the area belongs to the eastern Central Asian Orogenic Belt where strong tectonic and magmatic activities have occurred since the late Proterozoic. The crater was entirely formed within the bedrock of Cretaceous granite and appears as a bowl-shaped structure. Approximately one-third of the southern part of the crater rim has been significantly eroded and mostly removed; otherwise, most of the crater rim is well preserved. In a panoramic view, the crater appears as an unclosed ring mountain surrounding a circular depression, and it has steep walls and a relatively flat floor. The crater rim raises approximately 70–120 m above the surrounding terrain. The maximum elevation of the crater rim over the present crater floor is approximately 150 m. Most of the crater rim is composed of granite impact breccia varying from granules to boulders in size. The crater’s interior has been filled by a large amount of granite impact breccia at the bottom and lacustrine deposits at the top. The target rock of granite contains abundant quartz. This study investigated the planar deformation features (PDFs) in the quartz, which is one of the commonest shock metamorphic features in numerous terrestrial impact structures. For the investigation, granite impact breccia was collected from the crater floor. Most of the samples were made into polished thin sections for identifying the PDFs in quartz. Some fine-grained fragments of quartz were also collected from the samples for observation and analysis. The crystallographic orientations of the quartz PDFs were observed on a 4-axis universal stage under an optical microscope. No PDFs in quartz were observed in the quartz of large granite breccia fragments, but many PDFs appeared in the quartz of the fine-grained samples. One to four sets of PDFs in quartz were observed. The forms of the PDFs with Miller indices, such as (0001), { 10 1 ¯ 1 } and { 10 1 ¯ 3 }, were indexed. The observed multiple sets of PDFs in quartz provide unambiguous evidence of shock-metamorphism and confirm an impact origin of the structure. The topographic and structural features of the crater, as well as the occurrences of crater-filled materials (impact breccia and lacustrine deposits), characterize a bolide impact site. Based on 14C dating of the lacustrine deposits from the crater floor, the Crater Lake disappeared approximately 10 ka ago; this disappearance can be related to the loss of crater rim in the southern part of the crater. The large-scale absence of the crater rim cannot be explained by tectonic activity, normal weathering, or erosional process, and must correspond to directional erosion caused by a specific exogenic geological process after the formation of the impact crater. The geologic agent, mechanism, and history of the strong erosion of the crater rim require further investigation. The Yilan crater is the second confirmed impact structure in a large country (China) with an area of 9.6 million square kilometers.

MONITORING OF KARST PROCESS IN THE SOUTH URALS AND CIS-URALS (CURRENT STATUS, PRINCIPLES OF ORGANIZATION AND MANAGEMENT METHODS)

The territory of Southern Ural and Cis-Urals is a classic region of development of sulfate and carbonate karst. Within it, karst rocks are spread over 50% of the territory, almost 30% of the area is affected by surface karst forms, 45% of the urban and at least 20% of the rural population live in karst development areas. For the region, it is very relevant to predict the development of this process in order to assess danger and risk, to prevent its impact on engineering facilities and socio-economic facilities in a prompt and timely manner. Forecasting of karst activation is possible on the basis of monitoring data, which is not properly organized and conducted in the territory of Southern Ural and Cis-Urals today, there is no scientifically based observational network. On the basis of modern typification of the territory by conditions of ground water nutrition and moistening intensity, landform, bedding conditions and composition of karst rocks, the nature and degree of their overlap by non-karst rocks, as well as karst danger of the region taking into account its economic development, a regional scheme of the karst monitoring network has been developed. It consists of 16 observation sites, which cover all the types of karst found in the territory of Bashkortostan. Methods of monitoring at the regional level are defined. The proposed network for monitoring the development karst at the regional level is recommended for implementation in the Republic of Bashkortostan as part of the monitoring subsystem of dangerous exogenous geological processes, which is an integral part of the system of monitoring the state of the subsoil of the Russian Federation. It is planned to store and process the data of mode observations using the GIS Map 2011domestic software product.

Experience of using non‐specialized unmanned aerial vehicles for aerial surveys in the studies of exogenous geological processes

The article reviews the experience of aerial surveys using a quadcopter DJI Inspire 1 PRO (unmanned aerial vehicle, UAV) for solving problems of engineering geodynamics. It describes the application of photogrammetry to estimate quantitative parameters of the studied objects, the experience of using UAVs to study flood processes in the Tunka valley (Russia) and erosion structures in the Ulaanbaatar agglomeration (Mongolia). The first UAV‐acquired data on debris flow alluvial fans and elementary drainage basins of erosion structures are presented. The ranges of UAV flight heights were 100–150 m and 1–30 m for local and detailed aerial photography surveys, respectively. Local surveys covered relatively large objects – debris flow alluvial fans and drainage basins. Detailed aerial photography aimed to investigate the granulometric compositions of debris flow deposits and to construct transverse profiles of erosion structures. Processed aerial photos provided a basis for a schematic map showing the distribution of accumu‐ lated debris flow deposits. The granulometric compositions of coarse fractions in the debris flow deposits were de‐ termined. Based on the survey results, 3D models of the fragments of the erosion structures and their cross‐sections were constructed.

Considering emergency hazards in construction and operation of infrastructures

The paper presents a forecast on how hazardous exogenous geological processes caused by whether natural or man-caused flooding may affect the condition of infrastructures. The authors propose using an integrated R-score, which is a linear combination of partial criteria R1, R2, R3, R4 of the weighting factor (the weight) ki; these criteria are determined by experts as a function of partial indicators or on the basis of foundation cracks and settlement observation data. Reducing the integrated R-score to nearly zero is what indicates a reduction in the emergency hazards by preventive and protective actions. To address this problem is imperative for cities, where the developed areas are non-homogeneous and vary in time and space. Such areas must be run in accordance with the fundamental principle of geological safety and reliability in the context of actual and potential flooding.

A Progressive Framework for Delineating Homogeneous Domains in Complicated Fractured Rock Masses: A Case Study from the Xulong Dam Site, China

As components of natural geological bodies, rock masses generally experience long-term endogenic and exogenic geological processes. Since the composition and structure of rock masses generally vary from one domain to another, it is necessary to divide rock masses into several approximately homogeneous domains before developing rock engineering designs. A progressive framework that integrates geological, geotechnical and structural aspects was proposed to demarcate homogeneous domains. The proposed framework was applied to identify the homogeneous domains along three exploration tunnels at the Xulong dam site. The demarcation of geological domains was mainly done by means of thin-section examination of rock specimens and outcrop investigation. Field observations and P wave velocity tests were used to distinguish the changes in the geotechnical properties of rock masses caused by rock unloading and weathering. The crack tensor, which can synthetically consider the orientation, dimension and volume density of discontinuities, was introduced to determine the structural similarity of rock masses based on in situ measurable quantities. The results show that the crack tensor can effectively distinguish structural differences and exhibits better performance than conventional orientation-based methods. A major advantage of the proposed progressive framework is that it provides a quantitative, logical and reasonable framework to delineate homogeneous domains based on the comprehensive utilization of available field data in a logical sequence.

Исследование влияния антропогенных факторов на изменение геоэкологического состояния оз. Ходжагасан Азербайджана

The paper considers the results of geoecological and geophysical studies conducted in the Khojahasan Lake basin in the Western part of Baku. The main purpose of the work was to study the anthropogenic impact on geoecological conditions of the lake. To assess the development of exogenous geological processes in the coastal zone of the lake and their impact on the environment, geophysical studies were carried out by the vertical electric sounding (VES). From 1990 to 2014, the physical and chemical characteristics of water and sediments were studied in a representative section of the lake. Metal concentrations, including such toxic elements as Cu, Zn, Cd, Sr, Ba, Pb, Cr, and Ni, were determined in the trace element composition of bottom sediments. It was revealed that since the mid-XIX century and especially since the second half of the XX century the high rate of population growth and urbanization in the territory of the Absheron Peninsula (in the Republic of Azerbaijan the name Apsheron was changed to Absheron) led to intensive use of natural resources and increased anthropogenic load on the environment. Technogenesis actively violates the natural cycle of matter and energy in lakes (limnogenesis), along with other natu- ral media, as lake basins are located in lowlands and often accumulate industrial, municipal, agricultural, and other discharges. Pollutants accumulated in the lake basin affect hydrobiochemical conditions, transform quantitative and qualitative indicators of the aquatic environment and bottom sediments. Factors affecting the lake landscape are ge- netically different, unequal in the degree and nature of the impact, as well as induration.

THE ECOLOGICAL ROLE OF CLAYS AND CLAY MINERALS

The article considers the ecological role played by clays and clay minerals in the ecosystem and the biosphere as a whole. The value of clays and clay minerals in the origin of life on Earth and the formation of RNA are analyzed, due to the periodicity of the microstructure of these minerals, their physicochemical activity and sorption capacity with respect to amino acids, nucleotides, proteins and RNA. The processes of interaction of clay minerals with organic matter are considered, including under conditions of hydrothermal conditions, which have specific features that contribute to the origin of life. In addition, the ecological functions of the lithosphere due to clays and clay minerals were analyzed. It is shown that clays and clay minerals perform the most important ecological resource function, being a valuable mineral resource and mineral, participating in providing biota (including humans) with various mineral and energy resources of minerals, in providing biophilic resources, in providing renewable resources (water, oil and gas), in providing resources of the geological space, etc. Also, the clays perform an important ecological geochemical function, which consists in their participation in the geochemistry processes of the lithosphere and the formation of specific geochemical barriers that perform protective ecological functions on the migration routes of various contaminants. The ecological geodynamic function of clays consists in their influence on the development of endogenous and exogenous geological processes affecting the state and functioning of ecosystems. Finally, the participation of clays in ensuring the geophysical ecological function of the lithosphere consists in their influence on the formation of both natural and man-made geophysical fields in ecological-geological systems. Thus, clays and clay minerals have a great influence on ecological and geological systems, they are involved in the formation of all the most important ecological functions of the lithosphere: resource, geochemical, geodynamic and geophysical. Among them, the most significant is the role of clays and clay minerals in ensuring the resource ecological function of the lithosphere.

Recognition of geological processes in permafrost conditions

Any evaluation of geological processes in the permafrost zone is complicated by the rigorous climate and the general inaccessibility of such areas, which has resulted in insufficient information on territories in permafrost zones. The aim of this study was to delineate areas of geological processes in the zone of the discontinuous permafrost of Western Siberia based on the example of the Beregovoe oil and gas condensate field. An integrated approach using remote materials, the data from a walk-over survey, and laboratory testing of soils for the future pipeline was used. To estimate the prevalence and dynamics of exogenous geological and cryogenic processes, we described the climatic, geomorphic, geological, hydrogeological, and engineering–geological conditions of the territory as the basis of their emergence and development as well as the methodical issues of remote sensing. The recognition of landforms produced by different geological processes depends on the size of the landforms being mapped, their morphological expression, and the contrast between the disturbed landforms and the surrounding undisturbed areas. We defined the interpretive signs of major exogenous processes in the satellite images of the area and created a map on a 1:100,000 scale showing the distribution of geological processes at different geomorphic levels. This approach can be used to assess exogenous processes in other Arctic and Subarctic areas.

Assessment of Operating Experience of Snow Polygons in Russia, Alternative Ways of Dealing with Snow

At present, in Russia, the main way to handle the snow falling on the territory of urban development is its storage at snow polygons. It is shown that the arrangement of snow polygons on unprepared sites increases the risks of the development of dangerous exogenous geological processes, including, may lead to flooding of urban areas and infrastructure. The Russian and foreign experience in handling waste from street winter cleaning is considered. The analysis of the existing Russian regulatory framework in the field of placement of snow. The negative consequences arising from the operation of snow polygons are considered.

FEATURES OF THE MANIFESTATION OF MODERN EXOGENOUS GEOLOGICAL AND ENGINEERING-GEOLOGICAL PROCESSES IN THE TERRITORY OF VITEBSK

Exogenous geological and engineering-geological processes (EGIGP) is one of the most dynamic factors in the transformation of the earth's surface, which significantly affects both the geological environment and human economic activity. The spread, the intensity of development and the scale of the consequences of the processes in urban areas are becoming more tangible every year, often causing significant material damage. The purpose of the work is to consider the specific manifestations of modern exogenous geological and engineering-geological processes on the territory of Vitebsk for the subsequent development of recommendations to the executive authorities and environmental institutions of the city on the organization of engineering protection of the territory from the adverse effects of EGIGP. The work is based on the results of engineering-geological and ecological-geological studies of the city’s territory, which were conducted by the authors from 2003 to 2017 as part of the scientific team of the biological faculty of Masherov Vitebsk State University. The studies included ground-based visual observations of the development of EGIGP, including mapping and photographing, compiling and analyzing the collected data, computer processing of observational data, various maps and satellite images. Research results indicate that among modern exogenous geological and engineering-geological processes and phenomena: erosion, suffusion, slope processes, failures, flooding, waterlogging and frost heaving of the territory, precipitation and deformation of buildings have been widely developed in Vitebsk. It is noted that the degree of their knowledge in the city is not high enough and very uneven. The formulation of works on the evaluation of the manifestation of these processes is, as a rule, sporadic. Nevertheless the results of studies indicate that the problem under consideration is relevant for Vitebsk and requires further study of EGIGP, their negative impact on the state of the geological environment and, as a result, the entire infrastructure of the city.

CLASSIFICATION OF THE MAIN FACTORS OF OIL OBJECTS INFLUENCE ON THE ENVIRONMENT

Influence on ecology is observed at all stages of oil field development: development and exploitation of oil field, construction of wells, falling production.At the stage of prospecting works it is low and has a short-term, mostly local appearance.During the construction of wells, exogenous geological processes cause area and depth effects due to the fact that the work that is being carried out is large-scale.At the oil field construction stage, the integrity of the ground begins to change and the integrity of the soils is disturbed due to the arrangement of cluster sites, access roads, power lines and other necessary external engineering communications. In addition, the formation of new forms of the surrounding relief begins.At the stage of field exploitation, the impact on the geological environment is manifested as the heating effect of wells on the ground. As a result, the depth of their freezing and melting will change; water-filled funnels are created, flooding and water logging occur near oilfield areas.As a result of the analysis, it was concluded that the calculated emission values correspond to the maximum permissible values.

A Brief Analysis of Cave Types of Danxia Landform in Xinjiang Basin

The Xinjiang basin’s tectonic site properly on the suture where the two plates of Yangtze and Cathaysia collided. It had suffered an evolution history from rift basin to fault basin affected by Movement of Pacific Block since Mesozoic and had deposited a set of huge thick bedded terrestrial facies fragmentary system. There developed amount of Danxia Landforms in the basin with the effects of exogenic geological process. Cavernous weathering is the common phenomenon in Danxia Landform areas. The evolution of Danxia cave is controlled by lithologic characters, cleavages and fissures. The siltstone and sandstone and pebbled sandstone interlayers of Upper Cretaceous Chongan Formation are the principal stratigraphic position of forming the caves. It is considered that the devolvement of the caves in the surveyed area frequently results from the synthetic action of multifold external powers, just as the weathering denudation, water currents, and gravitational force.

Assessment of exogenous geological hazards in Moscow, Russia

Exogenous geological processes are exerting a significant impact on urban geo environment in Moscow endangering both surface and subsurface constructions. For surface construction, the principle geohazards in Moscow are karst-suffosion sinkholes, land subsidence, landslides, and waterlogging. The subsurface construction is endangered by karstification and fracturing of limestone, decompaction and swelling of clay, quicksand phenomena, and groundwater breakthrough to tunnels. Different methods are applied to study geohazards depending on the purpose and the scale of study. At the preliminary investigation stage, small-scale mapping and zoning of city surface or subsurface appears to be the most appropriate for the qualitative assessment of the risk of economic losses caused by exogenous geohazards. Assessment of the geological risk in Moscow was carried out separately for already existing urban infrastructure and for future planned construction. For existing surface urban infrastructure, geological risk is considered to be an integral parameter of probable damage caused by geohazards and the anthropogenic load on the specific territories. The main aim of risk mapping in this case is outlining the territories, for which restrictions and prohibitions should be imposed for further urban engineering development. For future subsurface urban construction, the risk-analysis consists in assessing the impact of geohazards on the engineering structure by comparing the future expenditures for the construction and operation under different engineering geological conditions. The risk maps in this case will help planners to compare and make alternative project decisions in order to minimize the cost in future economic expenditures. Both approaches are successfully approved in this investigation in Moscow.

Landslides monitoring – hazard and risk management case study

AbstractIn recent years, the interest in the assessment of hazard and risk of land sliding and in developing a warning systems and land utilization regulations aimed to minimizing the loss of lives and property without investing in long‐term, costly projects of ground stabilization has increased greatly. To be able to quantify both landslide hazard and risk a comprehensive landslide inventory is needed. A method used worldwide these days is to portray the spatial distribution of the landslides hazard and risks in maps. This paper presents in a case study for a territory from Republic of Moldova ‐ the types of works performed and the results for evaluating the trends in the evolution of exogenous geological processes (PGE) and the changes in the geological environment over time. All the results were used to make an annual forecast of the land sliding processes that could be use by interested state structures in order to establish a program of measures to protect the environment against sliding.

Evaluation of the extent of favourableness of the territory of the Odesa Region for placement of solid household waste landfills

The substantiation of selection of places for possible placement of modern interdistrict landfills of solid household waste (SHW) in the territory of the Odessa Region is an urgent task of ensuring ecological safety and sustainable development of the region. The purpose of the work is to assess natural and socio-economic conditions across the administrative districts of the Odessa Region in connection with substantiation of selection of places for possible placement of modern SHW landfills. The scope of the study includes solid waste landfills. Subject of the study covers substantiation of selection of places for possible placement of SHW landfills in Odesa Region. A critical analysis of the regulations containing the requirements to modern SHW landfills and their locations formed the methodological basis of the work. When carrying out the study published data and materials of own research were used. Schematic maps were built using one of the tools of Geographic Information Systems (GIS) - the Quantum GIS package. To estimate the degree of favourableness of the territory of the Odesa Region for placement of SHW landfills the following indicators were used: estimated volumes of SHW formation, thousand tons per year; relative area of dumps and landfills (%); module of total technogenic load; relative area of land damaged by erosion processes (%); relative area of impounded and potentially impounded lands (%); relative area of development of karst occurrence (%); number of landslides within the area; relative area of development of technogenic exogenous geological processes (%). The above indicators are expressed in points: 3 points - favorable conditions; 2 points - relatively favorable conditions; 1 point - unfavorable conditions. At this stage of research it is impossible to establish which of these indicators is a priority. According to the analyzed physical and geographical, engineering and geological, hydrogeological, technogenic and socio-economic indicators the possibilities of placement of modern interdistrict SHW landfills within the territory of the districts of the Odesa Region are nonequivalent. Theoretical and practical importance: an effective system of greening recreational and tourism activities will help to improve the environment within the territory of the National Nature Park in the Lower Dniester Basin.

Regional environmental programs of Dnipropetrovsk region: analysis, mapping, degree of implementation

The article is devoted to the geographical analysis of environmental problems and regional targeted environmental programs implemented in Dnipropetrovsk region. Geographical location, natural resources and human potential of the region contribute to the development of large enterprises in the extractive, metallurgical and chemical industries, which relate not only to material and energy-intensive industries, but also to environmentally hazardous facilities. As a result of the analysis, groups of environmental problems in the region were identified. Among them, the main ones are: pollution of the atmosphere and hydrosphere; violation of the natural water and hydrobiological regime of rivers; formation and accumulation of large volumes of industrial and domestic waste; storage of radioactive waste on the territory of the region and urban agglomerations; spread of dangerous exogenous geological processes; protection, use and reproduction of wild fauna and flora and a low level of conservation. These types of environmental problems are inherent in other regions, but in Dnipropetrovsk region they are of a higher level and therefore require special attention. It especially concerns accumulation of huge volumes of industrial wastes, including toxic wastes, as well as the storage of large volumes of radioactive waste on the territory of the Dnieper-Kamyansk agglomeration, which are a threat to the health of millions of people. It has been established that the largest number of nature protection measures is implemented within the framework of the program for eliminating the consequences of territorial flooding, but the largest amounts of funding are provided for under the solid waste management program. In the framework of these programs, nature protection activities are financed mainly from regional funds (48-50%), while other sources account for almost 30%. Environmental protection measures implemented in the region are grouped into five groups: organizational and management; engineering; engineering-geological; bio-meliorative; educational. A series of maps reflecting the severity of environmental problems in the region, the amount of funding and the degree of environmental measures implementation has been created. The study shows that the environmental situation in the region has improved both due to the implementation of regional environmental programs, and reduction of the negative impact on the environment due to a decrease in industrial production. Inadequate financing of environmental measures is exacerbated by the lack of a systematic approach to solving environmental problems of different nature and level.
