Abstract
This paper evaluates the ecological and geochemical status of soils in the Opuksky Sanctuary, Republic of Crimea, Russia. The Sanctuary has been a nature reserve since the mid- 20th century. It is located on the Black Sea coast of the Kerch Peninsula, the Republic of Crimea. This is an integrated sanctuary established to preserve the unique steppe ecosystems associated with the limestone massif of Mount Opuk and Lake Koyashskoye, a salt lake which has a number of one-of-a-kind nature sites within a small area and features several rare species. The water area of the Sanctuary is a wetland protected international under the Ramsar Convention. The increasing anthropogenic pressure arising from agricultural and industrial development of the Crimean Peninsula, as well as the increasing tourist flow that must be controlled is what makes monitoring the area critical. Soil is the most sensitive natural environmental component to anthropogenic effects; as such, it was monitored over three years from 2017 through 2019 as part of St. Petersburg State University, Department of Environmental Geology’s student internship co-organized with the administration of the Sanctuary. This effort produced a map of heavy metals in the local soils. The authors described the patterns in pollutant migration; they also prove why the soil was vulnerable to contamination. The research effort was the first to collect data on the background presence of trace elements in the soils of potentially uncontaminated areas; this data could be of use for engineering and environmental surveying across the region. Such data is becoming relevant and essential as the Republic of Crimea’s heavy industry and agriculture are rising.
Influence of Groundwater in the Base of the Gas Pipeline During the Formation of Aufeis
Authors: Permyakov P P , Vinokurova T A , Popov G G 
Published: March 2021

Abstract
Pipelines with a large length in permafrost areas pass through various water passages. In winter, due to various types of waters – underground, river, and lake (often ice has mixed nutrition) – we observe the formation of aufeis. When they repeatedly pour out onto the surface and layer by layer freezing, plane-convex ice bodies are formed – aufeis. The heat and mass transfer interaction of a gas pipeline with a frozen ground base is considered during the filtration of permafrost groundwaters. Numerical modelling was carried out taking into account the real thawing process – freezing of the pore solution in the temperature spectrum at various temperature regimes of filtration of permafrost groundwater. As a result of a numerical experiment, it was established that aufeis formation occurs in the second half of winter and has a warming effect. In the first half of the summer period, intensive thawing of aufeis is observed, and the dynamics of the depth of seasonal thawing occurs with some delay, but at the beginning of the winter period, it is restored, as in ordinary soil. Long-term seasonal filtration of groundwater with a natural temperature of the environment has a warming effect on the temperature regime of frozen rocks. Warming and increased water saturation of the frozen soil base are accompanied by negative seasonal permafrost processes.

Environmental Risks Caused by Floods in Built-Up Areas
Authors: Arefyeva E V , Muravyeva E V , Maslennikova N N 
Published: March 2021

Abstract
The article considers the possible consequences of flooding for the ecological state of territories, sets the tasks of risk assessment and prevention of damage from dangerous hydrological processes. The authors discuss possible ecological consequences caused by flooding for ecosystems and built-up areas and suggest methods for risk assessment and risk management in flooded areas. Natural and anthropogenic factors of floods and issues of predictability of hazardous hydrological processes are also considered. The article shows that the risk of a disaster, the initiating factor of which is a flood, occurs when hydro-meteorological, geological and other hazards interact with vulnerability factors of a physical, social, economic and environmental nature. It is proposed to take an extreme hydrological event of low probability as a scenario of a catastrophic event, for example, the historical extreme of the maximum water flow. As an example, we consider the decisions taken to prevent flooding in built-up areas on the example of the Kuban river basin of the Krasnodar territory.
A Socioeconomic Development Concept for Russia’s Specially Protected Areas to Address the Negative Anthropogenic Impact: Evidence from the Tunkinsky National Park
Authors: Afonina T E , Lazareva A A 
Published: March 2021

Abstract
Russia’s natural parks (NP) are critical for the preservation and recovery of the natural environment and biodiversity. NPs were mainly created to preserve the landscape- forming biotopes. Siberian and Far Eastern NPs were founded in the late 1980s or early 1990s. As a result, previously human-populated or otherwise affected areas that contained settlements, logging sites, mining sites, collective farms, and other economic facilities were transformed into national parks. A national park is supposed to provide venue for research and recreation, which is at odds with the locals’ economic activities. Irrational recreational use of NP areas degrades the plant communities: vulnerable species vanish, less vulnerable replace them, and meadow species become widespread in forest ecosystems; it also negatively affects the soil cover as it destroys the ground litter of soils, makes the humus horizon shallow and too dense, ultimately killing the soil microflora. This is the case of nearly any NP in Siberia and the Far East, which calls for well-thought-out economic zoning of areas that would be environmentally, economically, and legally sound. It is on this basis that this paper proposes a socioeconomic development concept (the Concept) for the Tunkinsky NP.

Published: March 2021

Abstract
Currently, the problem of organizing permanent car storage places is relevant due to the high growth rate of motorization in the world. At the same time, excessively large Parking lots have a negative impact on the environment. The article considers various types of Parking lots and the main factors of their impact on the environment. A map of dispersion of emissions of harmful substances such as nitrogen oxides, carbon monoxide (II), total hydrocarbons for the city of Naberezhnye Chelny is constructed. To calculate the amount of emissions from one car in the Parking lot, a model is built in the AnyLogic simulation environment. The relationships between the number of Parking spaces and the amount of emissions from cars in the Parking lot were calculated and analyzed. It has been experimentally established that the more Parking spaces in a Parking lot, the longer cars search for Parking and, consequently, the more impact on the environment.

Unique Ecoregion-East Siberian Taiga: Approaches and Ways to Implement the Ecoregion Concept
Authors: Belousova S V 
Published: March 2021

Abstract
according to Russian and international experts, the East Siberian taiga is not only practically the only natural ecosystem in the country, but is also one of the "global ecoregions" that have been identified by WWF as the most valuable territories in terms of preserving biodiversity on a global scale. At the same time, the current use of this territory is characterized as extremely depleted, due to the high level of illegal logging, the scale of forest fires and the current nature of forest management and reforestation. One of the reasons for this is the extremely low efficiency of forest resources management against the background of high corruption of the authorities in this area, which creates additional risks and losses. In these circumstances, it seems necessary to create large-scale environmental conservation project of the East Siberian taiga, perhaps in conjunction with WWF, which implements, including the biodiversity conservation project in the Altai-Sayan Ecoregion. The principles and approaches of the latter within the framework of the forest program can serve as a basis for conservation measures of the East Siberian taiga. The article analyzes the problems and conditions for implementing the main principles of the forest program of the above-mentioned WWF project in relation to the East Siberian taiga and suggests additional measures to protect the unique Ecoregion.

Abstract
This work is carried out in order to identify the most effective mode of operation of the membrane-assisted gas absorption setup in the problems of ammonia recovery. The study was conducted to determine the effect of the adsorbent layer thickness on the efficiency of ammonia separation from a binary mixture of NH3/N2, with an ammonia content of 15 vol.%, by the method of membrane-assisted gas absorption. The study used a commercially available elastomeric poly(dimethylsiloxane)poly(diphenylsesquioxane) membrane (LESTOSIL™) as the membrane, and an aqueous solution of PEG-400 was used as the absorbent. The experiment was carried out at seven different thicknesses of the absorbent layer, from 0 (without absorbent) to 6.5 mm, for each of them the separation efficiency value was obtained at a gas flow of 30 ml/min. There is an inversely proportional dependence of the ammonia concentration in the retentate stream on the thickness of the liquid absorbent layer. The highest separation efficiency (4375.48) was achieved with an absorbent layer thickness of 6.5 mm.

Stability of Artificial Urban Slopes to Mini-Landslides
Authors: Chuchkalov S I , Alekseev V V 
Published: March 2021

Abstract
The growth of cities causes changes in the natural landscape and is associated with the construction of structures on natural and artificial slopes. In this regard, large areas become susceptible to landslide danger. The paper considered slip microslides that appear on the slopes of urbanized areas. The functional dependence of the coefficient of friction in soil on moisture, density and type of soil was obtained on the basis of considering soil moisture as a phase that has interfaces with soil air and the solid phase of the soil. For gray forest and soddy podzolic soils, the values of moisture content (0.30±0.04 m3/m3 and 0.22±0.04 m3/m3, respectively) were revealed, at which the stickiness of the soil begins to affect the friction. Using the obtained dependence of the coefficient of friction in the soil on moisture, density and type of soil, an expression was proposed to estimate the ratio of the thickness and length of a landslide for various angles of slope inclination. The carried out numerical estimates of geometric landslide characteristics were consistent with real landslide processes on artificial slopes of urban planning objects.
