The article analyzes the impact of displacement that taking place at the mouth of the Don River. This leads to a weakening self-cleaning process of water and increasing concentrations of contaminants. The basic sources of pollution of waters of the river Don and the main types of anthropogenic impact on the aquatic ecosystem. Cases of accidents in factories and transport, violation of wastewater treatment technology, as well as simply by negligence.The necessity of the control of non-periodic oscillations of water bodies located on them intakes, to prevent loss of quality drinking water supply. The main influence of these displacement prone city like Azov, Aksay, Bataisk and Rostov-on-Don. The conclusion about the necessity and the possibility of monitoring the state of the river Don, the organization without expensive continuous observation system with an extensive list of hydro-ecological indices.

In the article the basic problems of water reservoirs, their impact on the surrounding ecosystem. The advantages and disadvantages of the construction hydraulic structures. In particular, the example of the Tsimlyanskoe Reservoir. Identified the main tasks were solved and types negative impacts on the environment that appeared after construction of reservoir . The conclusion about the need to assess the environmental risks associated with the operation of the existing hydraulic structures modern methods and means of measurement. The formulas for the parameters of hydro-physical and hydro-chemical processes, such as hydraulic flow characteristics and reservoir temperature regime. The necessity of building an actual mathematical model for a series of computational experiments. Using the data obtained will allow for prediction of eutrophication processes in the Tsimlyanskoe reservoir.

Keywords: reservoir, hydraulic structures, ecology, hydrological processes, thermal pollution, eutrophication, mathematical modeling, numerical simulation, anthropogenic impact, drinking water supply, Tsimlyanskoe Reservoir.

In article authors considered the main processes having impact on distribution in atmospheric air of the polluting substances which are formed during the work of the enterprises of fuel and energy complex – boiler rooms and combined heat and power plant. Various changes to which are exposed gaseous and the strong polluting substances coming to the atmosphere with flue gases, and also the factors influencing dispersion and their concentration in the air basin of the cities are analysed. The climatic characteristics significantly influencing formation of pollution of the air basin of the cities are investigated. In the conclusion authors drew a conclusion that, despite an arrangement of installations of the centralized boiler rooms within an urban area or is close to it, decrease in pollution of the air basin of the cities in comparison with systems of autonomous heating of each house is observed.

In article authors considered organic types of fuel as the most widespread sources of obtaining thermal and electric energy at the enterprises of fuel and energy complex. The prevailing types of organic fuel – natural gas, coal, fuel oil are revealed, and also the composition of flue gases depending on a type of the burned organic fuel is analysed. So, when burning natural gas the main polluting substances are nitrogen oxides and carbon oxides. When burning liquid fuel oxides of sulfur and ashes are added to them. Coal burning, besides above-mentioned substances, leads to receipt to the air basin firm particles, particles (flying ashes) consisting from the zolovykh, not burned down solid fuel and soot. Negative impact of the enterprises of fuel and energy complex on environment components is investigated. In the conclusion authors drew a conclusion that, in comparison with other types of organic fuel, burning of natural gas does the minimum harm to environment.

In the work pointed out that currently the most common method for the disposal of solid waste production and consumption (JET) is to bury them in landfills. The authors have studied the requirements for the placement of landfills for disposal of municipal solid waste production and consumption and concluded that most of the already existing landfills POMB not in compliance with environmental regulations, and the construction of new landfills have not been fully taken into account environmental aspects and factors. We also study the features of the existing types of landfills for disposal of solid waste production and consumption. In conclusion, the authors concluded that the device ranges JET shall be in accordance with the established procedure for the design, operation and rehabilitation of landfills for municipal solid waste with the obligatory account climatic features of the area in question, geological and hydrological conditions of the terrain and conditions to ensure environmental safety.

The analysis of the main problems in the field of solid waste production and consumption in the city of Rostov-on-Don, determine the most important of them - the lack of separate collection of waste, low level waste recycling, insufficient waste treatment enterprises, inadequate coverage of rural service collection and waste removal, exclusion of large areas under waste disposal, illegal dumping. Studied the current system of handling tvedrymi waste production and consumption in the city of Rostov-on-Don, revealed its priorities, chief among them - increasing the share of industrial waste recycling and reducing the amount of waste to be disposed of. It is concluded that the lack of effectiveness of management of solid waste production and consumption and the need for a radical change in the existing strategy for waste management in the city of Rostov-on-Don.

The article describes the research of thermodurability of glass-carbon - one of the most promising carbon materials used in the production of luminophors and semiconductor materials, optical single crystals, etc. The aim of this work was to study the behavior glass-carbon in the course of thermo-cyclic testing. As a method of diagnostics of the birth and development of micro-cracks was used by the reception of signals of acoustic emission. It is shown that at heating in the samples glass-carbon there was a strong movement of dislocations in thermocyclic effects ,recognized in the signals of acoustic emission. As the number of pulses when heated above, than during the cooling of the sample, it is evidence of the accumulation of damages in the structure of the cyclic thermal processing glass-carbon samples. It is established, that the curves of the accumulation of defects at the pulses of acoustic emission, differ on the stage of heating and cooling. Proposed to use the curve of the aggregate accounts of acoustic emission pulses as a possible harbinger of destruction when heated glass-carbon of the product.
