Road Drainage System Development in a Siberian City

Negative consequences of global climate change and rapid urbanization are problems of combating urban floods, underflooding and increasing the safety of adjacent water bodies due to the washout of storm water and municipal waste. These problems are being solved slowly and ineffectively. This is explained by harsh climatic conditions in a large number of territories, higher number of abnormal rainfalls, insufficient financial injections into the construction of storm systems from the state and business structures, imperfection of regulatory documents based on outdated information for calculating projects. Conclusions are formulated on ways out of the crisis situation in the city of Tomsk (Western Siberia). It is proposed to improve the collection and drainage of atmospheric water from road sections.The relevance of the work is associated with the improvement of the system of atmospheric wastewater removal from the road pavement and urbanized areas, especially at abnormal volumes of rainwater.Purpose: The aim of the work is to assess environmental, economic and technological potential of Russian and foreign techniques to ensure effective storm water drainage and primary treatment of surface runoff.Methodology/approach: The analysis of the current state and prospects for the implementation of the best foreign practices for collecting, removing from urbanized areas, effective water drainage devices; comparative assessment of practices that are most suitable for continental climate conditions with a long cold period and significant amounts of precipitation; measures to improve the efficiency of storm water drainage; theoretical research of literary sources, theoretical analysis, interdisciplinary synthesis; methods of logical generalizations, patent analysis, search and statistical methods.Research findings: The paper highlights foreign achievements and problems of drainage and storm water treatment from urban roads. Increasing interest in biophilic engineering technologies includes stages of collection and removal of surface runoff water, its primary treatment, and evaporation or infiltration into deep aquifers. The state of the drainage problem in Russia is considered herein. Modern technical means capable of organizing a road drainage system and, if necessary, treating storm water are investigated. The main reasons for the unsatisfactory condition and insufficiency of road drainage systems are identified.Practical implications: Systematization and generalization of approaches to combating excess urban storm water serve as the basis for improving modern drainage systems in Russia. Foreign experience in draining, isolating, and recycling storm water can be used and developed in different natural and climatic zones of Russia with respect to the specifics of their geoecological situation.

Geoecological functions of the Baikal endemic amphipod Gmelinoides fasciatus in the bottom subsystem of the cooling reservoir of the Chita TPP-1

The geoecological situation in the natura-technical geoecosystems of Baikal Asia is complicated by the invasion of alien species. Information about the Baikal endemic amphipod Gmelinoides fasciatus that penetrated into the cooling reservoir of the Chita TPP-1 is insufficient to assess the current geoecological situation in the benthic subsystem of the cooling reservoir. The purpose of our research of the study was to identify the geoecological features and functions of Gm. fasciatus affecting the geoecological situation in the benthic subsystem of the Chita TPP-1 cooling reservoir. In 2022–2023 the Gm. fasciatus distribution, size structure of the population and elemental composition have been studied in Kenon Lake. It is established that Gm. fasciatus has settled the coastal zone of the lake, the size and structure of the population indicate its stability. The P content in the crude mass of Gm. fasciatus in the lake is 29.7 kg, Ca — 444 kg, Cu — 0.28 kg. Due to the Gm. fasciatus invasion in Kenon Lake, in the monitoring and management system of the cooling reservoir, it is now possible to use a new indicator of the state of the bottom subsystem. Invasion of the amphipod Gm. fasciatus entailed a change in the geoecological situation in the cooling reservoir of Chita TPP-1 — Kenon Lake.

ПУТИ ВОВЛЕЧЕНИЯ НЕВОСТРЕБОВАННЫХ СЕЛЬСКОХОЗЯЙСТВЕННЫХ ЗЕМЕЛЬ ВЛАДИМИРСКОЙ ОБЛАСТИ В ЭКОНОМИЧЕСКИЙ ОБОРОТ

The article, using the example of the territories of the Troitsky and Novomoskovsky administrative districts (hereinafter referred to as TiNAO) of Moscow, shows the possibility of a geoecological assessment of changes in the morphometric parameters of small reservoirs. Before joining the administrative structure of the Moscow territories in 2012, the studies on the ecology of these territories was minimal. Of particular importance for monitoring the geo-ecological situation in “New Moscow», – what the conjoined territories are also called, is the fact that its area is 1,480 km2, which is 57.8% of the entire territory of Moscow.
 The subject of the study were 1402 small reservoirs registered in the territory of the TiNAO. To carry out their environmental assessment, a cluster analysis method was used, which is a universal mathematical tool for scientific research. A negative change (decrease) in the average depth of the reservoir was taken as the main parameter of the study. Based on the results of the objects’ morphometry analysis carried out at an interval of two years, data on dynamic changes in the physical parameters of reservoirs were obtained and processed. It was established that shallowing problems exist in 4.51% of the total area of reservoirs in the TiNAO. Mapping stagnant small reservoirs made it possible to visually assess the scale of the problem and identify potentially problematic areas of the TiNAO from a geoecological point of view. Using the cluster analysis, zoning of problematic water bodies was carried out. Such identification (clustering) of water bodies’ grouping made it possible to see deviations at the level of groups of small river basins, which provided a large-scale understanding of the ecological situation at the level of catchment areas of larger water bodies.

Assessment of land cover changes in Andijan region for 1997-2020 using remote sensing


 
 
 Remote sensing (RS) plays a vital role in mapping of land use/land cover (LU/LC) and in quantitatively assessing the effect of human intervention on natural resources. In this study, the land cover analysis and correlation method for a certain period of time was used to classify the land cover of Andijan region with Landsat satellite images of 1997-2009-2020. A classification method combined with clustering was used to determine the land cover change, and a study was conducted using Google Earth software through 30 classes. The analysis shows that compared to 1997 (566.6 km2), the area of buildings and structures in the study area has expanded to 750 km2 in 2009 and in 2020 it was 770,4 km2, an increase of almost 1.4 times. Another aspect is that there is a decrease in the class of forested areas, gardens and cultivated fields. In particular, in 1997, the area of this class was 3047 km2, and by 2009 it had decreased to 2,430 km2. Thanks to the measures aimed at improving the geo-ecological situation, by 2020 the amount of the «green cover» was 2,644 km2. In Andijan region, empty lands (bare soils and barren lands) amounted to 678.8 km2 in 1997 and had increased to 1,115 km2 (1.6 times) by 2009. In 2020, the area of degraded lands had decreased by 858 km2. The results of remote sensing studies show that the expansion of construction and bare land has led to a reduction in green space. The amount of dust in the atmosphere rises when green space decreases. Another object representing the geo-ecological situation is water bodies, which has in- creased in the studied area. Initially, water basins were initially 9.65 km2 in 1997, decreased to 7.77 km2 by 2009, and reached 29.63 km2 by 2020. This study was carried out in order to determine the formation of agglomeration in the small and densely populated Andijan region, to study the effective use of limited land resources.
 
 

Элементный состав растений семейства рясковые (Lemnaceae) как индикатор природно-техногенных обстановок территории Томской области

The work is devoted to the study of the indicator properties of the elemental composition of aquatic plants of the duckweed family (Lemnaceae). This plant family can act as an optimal geoindicator due to its wide distribution area, high rate of biomass growth and resistance to eco-geochemical environmental conditions. The carried out research touches upon one of the most pressing problems of geoecology and ecogeochemistry, the search for objective indicators of the state of the environment. The data are presented on the content of 28 chemical elements in duckweeds, determined using instrumental neutron activation analysis. Statistical indicators of the variability of chemical elements depending on the natural and man-made conditions of the regions of the Tomsk region have been studied. The object of the research isaquatic plants of the duckweed family (Lemnaceae). The purpose of the research is to determine changes in indicator indexes of the content and ratio of chemical elements in the composition of plants of the duckweed family, depending on the ecological and geochemical situation of the Tomsk regionterritory, formed as a result of the complex influence of natural and man-made environmental factors. Using geochemical approaches, the formation specifics of the elemental composition of aquatic plants depending on the geo-ecological situation of the region have been determined, indicator indexes of the rare earth and radioactive elements ratio have been identified in the areas where oil refining industry enterprises, the nuclear fuel cycle are located, as well as the presence of natural anomalies. It has been established that the La/Ce ratio in duckweeds of the Tomsk region varies within a narrow range from 0,2 to 0,6, the ave­rage value is 0,4. The value of the Th/U ratio varies over a wide range, from 0,02 to 154. In general, it has been shown that the elemental composition of aquatic plants of the duckweed family carries information about the current ecological and geochemical situation of the study area and can serve as an indicator of the environmentstate.

Physical and chemical properties of soils and technogenic surface rock formations in dumps of coal mines in Rostov oblast

The physical, chemical and physico-chemical properties of soils and man-made surface formations of the territories of coal dumps in the southeastern part of the Donetsk ridge within the Grushevsko-Nesvetaevskaya syncline (Rostov region), differing in age, lithological properties of the overburden and host rocks composing them, and pyrogenic dynamics, have been studied. The main characteristics of the soil properties of the studied territories have been established to assess the geoecological situation, patterns of the spread of potentially toxic substances and the development of projects for the restoration of territories. The unequal influence of soil formation factors was revealed, manifested in high variability and contrast of soil properties. Electron microscopic studies of technogenic samples have shown that the coarse microstructure was formed as a result of the impact of modern compaction, cementation and sintering processes on the rock.

Fundamentals of the landscape diversity conservation strategy in the regional environmental policy

The need to preserve natural systems is determined by the adaptive demand for ecosystem services in a worsening geo-ecological situation. These services are provided by natural systems preserved in a natural or close to natural state. The quality of services depends on the diversity of the environment, including the landscape diversity (LD). The study aims to develop principles the natural resources conservation strategy relies on in developing the regional environmental policy (REP). The article shows that some of the principles are based on the landscape approach, and some of them - on the conditions and requirements for the application of parameters and criteria for assessing human resource management. The principles were considered using the example of Northern Sikhote-Alin in Khabarovsk region. The landscape-ecological zoning was based on the landscape approach. Geosystems of high regional environment-forming significance were identified to adjust the goals and objectives of strategic territory planning. It is more appropriate to reflect the effectiveness of measures intended to preserve human resources in regional program-target documents, tracking spatial development indicators recorded in the regional economic policy of a territory.

Geoecological situation in the region of the Erdenet mining and processing facility (Mongolia)

The Erdenet mining and processing facility (Mongolia) develops a large copper-molybdenum deposit. The volume of waste in the tailings dump of the enterprise reaches 600 m. m3and its area is more than 1300 hectares. Quarries and tailings pits release significant amounts of persistent pollutants into the environment. They penetrate groundwater and surface water and also spread as dust. The results of comprehensive geochemical and geoecological studies indicate the irreversible anthropogenic transformation of the area. In 25 years, the operation of the Erdenet deposit will be terminated. Mongolian government decided to develop a “Concept of the program for closure of the enterprise, and further development of the area”. Based on the results of this research, it is proposed to identify several areas and develop special renovation projects for each of them. An enterprise for the production of construction materials can be created on the tailing’s dumpsite. Companies extracting residual amounts of valuable elements from waste can be profitable. The network of transport communications of the deposit can ensure the operation of facilities in areas of mining landscapes and technogenic geochemical anomalies. After planning the terrain and covering the surface with insulating materials on these sites, a technology park can be organized. Implementing these projects as part of a single program will provide jobs for the Erdenet residents, and the budget revenues generated by their operation will allow for the renovation of the urban area.

Update of the generalized environmental assessment and inertial forecast for the development of a cluster of urban areas of the Bogorodsky urban district of the Moscow region within the framework of the system “Ecology, environment and public health”

The article presents an update and a generalized geo-ecological assessment of the Bogorodsky urban district of the Moscow region (the former Noginsky was abolished) at the time of 2021-2022. The indicators of the ecological state of the territories are considered from the standpoint of the realities of the current years. A comparison was made of the geo-ecological situation of the territories of small towns of compact residence in the Noginsk district for 2011-2014 and the current geo-ecological situation of the territory of small towns of the Bogorodsk urban district of the Moscow region (the former Noginsk was abolished) for 2021-2022. Data on the incidence of the population and environmental pollution are analyzed from the standpoint of causal relationships of direct and indirect correlations between diseases of the respiratory, digestive and genitourinary systems. Also, for ecodiagnostics, the dominant concepts of toxicology are used, such as the reaction rate and the response of a particular individual organism to a stimulus. A new municipal specialized subprogram “Ecology and the Environment” for 2023-2027 with the introduction of new indicators aimed at protecting the environment is considered. A look at the scenarios and inertial forecast for the development of environmental sustainability of urbanized territories of small towns in the study area is given.

INFLUENCE GROUNDWATER PRODUCTION AND EXPLOITATION ON ECOSYSTEM CHANGING IN AZERBAIJAN

The Azerbaijan Republic is located in the arid climatic zone and due to this feels deficit of general water balance. The production and utilization of the groundwater caused negative consequences that affected on natural conditions of different regions. For example, in Qanikh-Ayrichay fields we can notice abnormally high hydraulic interrelation between ground and surface waters, and underground component of the river drain in the natural conditions forms approximately 55-65%. When infringing given conditions by production the groundwater the decrease of their average level forms approximately 50-60 meters. The appeared depression funnels cause tightening of the additional volume of river run-off to the groundwater intake wells, that is damage river run-off. Given volume of the river run-off must not be calculated twice when assessing the common water balance of the region. And another fact, the decrease of the groundwater level in a part of Gusar region has created some ecological problems. In the region of development of the relict forests the dynamic levels of the groundwater decreased on 25-30 meters. This affected root-inhabitable stratum and as a result led to abrupt aggravation of the ecological situation of the regions. It was required to optimize the production of the groundwater. Opposite situation is observed in the Absheron Peninsula where there are almost no fresh water resources. The water demands are met by surface water resources of Samur river and groundwater transfer from Guba-Gusar region of the Republic (more than 200 km from the demand areas). These sources are augmented with water from Kura river in the Ali-Bayramli region (more than 180 km from the demand area), at rates of up to 30 m'/sec. Due to the specific hydrogeological conditions, absence of sewerage system and etc., it leads to land subsidence, landslide processes, flooding, and other environmental and social phenomena and abrupt aggravation of the geoecological situation of the peninsula, in the whole. As it has already been mentioned a big part of groundwater in Azerbaijan is utilized for irrigation of agricultural crop. Mostly we notice fresh (up to1.0 g/l) or weakly saltish (up to 3.0 g/l) hydrocarbonate-sulphate and sulphate - hydrocarbonate waters with different cationic composition. The combination of cations form irrigation factors of the groundwater and as a result forms opportunity to utilize it for irrigation of concrete soils. Incorrect calculation of given qualitative parameters in the "water-rock" system has led to salinization of the soils of irrigated areas of Mil and Mugan-Salyan plains and accordingly led them to exit from the crop rotation. At present time, melioration of these areas is realizing. Thus, we can certify that production and utilization of the groundwater is essential anthropogenic factor, which influence on geoeco-logical situation of the republic. This factor must be taken into account when forecasting water-related activities in the whole and concerning exploitation of the groundwater, in particular. Keywords: water-bearing horizons, aquifer, water-saturated series, water-economy balance, gravel-pebble sedimentation, depression funnel, Mil and Mugan-Salyan plains, exploitative reserves.

Классификация напряженных геоэкологических ситуаций и их ландшафтная обусловленность (на примере Волгоградской области)

Currently, the geoecological situation is the main structural unit in the comprehensive study of modern problems of nature management and the main subject of environmental mapping at any spatial level. Each geoecological situation is formed within a specific geosystem and depends on its properties, structure, dynamics, functioning, it also has specific time characteristics. The methodological basis is the geosystem concept, the doctrine of modern landscapes as natural-anthropogenic geosystems. The classification of geoecological situations is carried out by a set of signs, by a set of problems, by the type of anthropogenic impacts and their depth, by leading factors of formation, by the scale of manifestation, by the time of existence, etc. The determination of the severity of the geoecological situation depends on the regional characteristics and specifics of the leading problems and can be considered separately or from the point of view of the living conditions of the population and its state of health or from the point of view of the state of natural resources, geographical components, the preservation of natural geosystems, the uniqueness of landscapes and the gene pool of living organisms. When determining the severity of the environmental situation, an ecocentric (geocentric) integrated approach was used. It allows you to objectively assess the situation in terms of the state and degree of change in geosystems. As a result of the research, it was established that about 63 % of the territory of the Volgograd region is characterized by a conflict and tense geoecological situation. A satisfactory geoecological situation is observed in western areas characterized by the best bioclimatic indicators, the lowest population density, and the level of anthropogenic load. A tense and critical geoecological situation is typical for areas where mining enterprises, large industrial centers are located, as well as for areas that are characterized by a low level of environmental stability of natural geosystems

GEOECOLOGICAL ASSESSMENT OF LAND USE STRUCTURE OF GNIZDECHNA SMALL RIVER BASIN

Gnizdechna river is a right tributary of the Gnizna river (Dniester basin) and flows in the central part of the Ternopil region. The length of the river is 39 km, the area of the basin is 26 400 ha, the average depth is 1,5 m, the slope of the river is 1,8 m/km. The valley of the Gnizdechna river is partially melioration and regulated, there are 4 ponds on the river. The aim of the article is to assess the geo-ecological parameters of the land use structure of the small Gnizdechna river basin. The following methods were used to achieve this goal: descriptive, geoinformation, statistical, mathematical and geoecological analysis, as well as special methods for determination the anthropogenic load, coefficients of ecological stability and anthropogenic transformation of the Gnizdechna river basin. The structure of land lands in the Gnizdechna river basin was analyzed. It was found that the structure of land use of the study area is dominated by arable land (65%), forests occupy 10%, built-up land - 6%, pastures - 9%, hayfields - 5%, perennials – 1,5%, land under water and swamps – 1,5%. The share of natural lands in the Gnizdechna river basin is 27%. The reserve of the basin is 17% (22 objects of the nature reserve fund, with a total area of 4420,5 hectares).
 According to the results of calculations, the article defines the coefficient of anthropogenic transformation landscapes of the Gnizdechna river basin which is 5,88; the coefficient of ecological stability of the study area - 0,3; anthropogenic load score - 3,7; anthropogenic load factor - 3,3. According to the obtained results, it is established that the territory of the Gnizdechna river basin is ecologically unstable with moderately transformed landscapes, rather high score and average degree of anthropogenic load. The prospect of further research remains the rationale for measures to optimize the structure of land use in the Gnizdechna river basin, in which it is necessary to provide for an increase in the forest cover of the study area by changing the purpose of individual land plots and the organization of their landscape-adapted use.
 According to the results of the geoecological assessment of the land use structure of the Gnizdechna river basin, it can be concluded that the landscapes of the study area are moderately transformed, ecologically unstable with a sufficiently high anthropogenic load. Such indicators are due to high agricultural development of the basin (82%) and, accordingly, plowing - 65%, low share of forested land (10%) and other natural lands (pastures, hayfields, perennials, underwater lands and swamps - 17%) . Which in turn forms a low share of natural lands in the basin of the studied small river - 27%. At the same time, in the basin of the river Gnizdechna there are 22 objects of the nature reserve fund with a total area of ​​4420.4 hectares, which forms a reserve of the studied area of ​​17%. To optimize the structure of land use in the Gnizdechna River basin, it is necessary to justify and implement a number of measures, which should be based on landscape-adapted land use, reduce plowing and increase forest cover, due to unproductive and highly eroded lands. The formation of an ecologically safe system of nature management in the basin of the studied small river will help to improve the geo-ecological situation in the basins of the rivers Gnizna, Seret and Dniester.
 Key words: Gnizdechna river, river basin, land use, anthropogenic load, natural lands, Ternopil region.

МЕТОДИКА ОЦЕНКИ ИНТЕГРАЛЬНОГО ЗАГРЯЗНЕНИЯ ПОЧВ (НА ПРИМЕРЕ ПРИАЭРОДРОМНОЙ ТЕРРИТОРИИ)

The paper deals with the problem of an objective assessment of the geoecological situation of the aerodrome environs according to standard methods used for calculating the total indicator taking into consideration the excess of the maximum permissible or background concentrations of pollutants. We propose a method for calculating a complex indicator that can take into account heterogeneous characteristics of soil pollution: the multiplicity of excess of conditionally natural background concentrations, the frequency of exceeding the maximum permissible concentrations of pollutants, their hazard class, the soil use category and ability of soils to regenerate. For this, we used transition from numerical values of soil pollution parameters to a vector space. The complex indicator of soil pollution involves totaling the lengths of vectors of established priority pollutants that have a high or extremely high impact on soil pollution according to a set of heterogenous parameters. The priority scale of pollutants is based on well-known scientifically grounded gradations of soil pollution parameters. With the help of standard and the proposed methods for calculating integral soil pollution, the geoecological situation was determined at a distance of up to 8,4 km from the reference point of the aerodrome during its regular operation and during reconstruction. The proposed combined indicator of soil pollution differs from the existing ones with greater accuracy and objectivity.
