Purpose. Analysis of environmental problems and risks associated with the construction and operation of small hydroelectric power facilities (SHEPP) in the Ukrainian Carpathians. Methods. Field studies, statistical, hydrological, hydroecological, analysis and synthesis. Results. Potential environmental risks arising from the construction and operation of SHEPP in the Ukrainian Carpathians are considered. The influence of Yavіrska hydroelectric power station on water discharges in the Stryi river was investigated. The daily water discharges for the two hydraulic sections located above and below the station for low-water (2003) and high-water (2008) years are analyzed. Possible risks in the construction and operation of the hydroelectric power plant for the movement of flood waters, river sediments, the development of riverbed deformations, and others, are indicated. The difference in water discharges between the two hydrological stations is presented, and it is confirmed that in the spring of 2008 and 2003 and the autumn and winter of 2003 and 2008 minimal differences in water consumption were observed as a result of the water retention in the reservoir above the dam of Yavіrska hydro power station for the maximal electrical power generation. The impact of the Yavіrska SHEPP on the biota of the Stryi river during 2014–2015 was analyzed. The obtained results indicate that the main negative factors affecting the communities of river hydrobionts are the creation of reservoir of limnethic conditions in the continuum of the river ecosystem; the accumulation of sediments and dead organic matter on its bottom and banks and the demolition of these sediments on the lower sections of the channel bed; also a decrease of water in the riverbed downstream of the dam after the closure of the floodgates in June. The analysis of the environmental impact assessment reports made it possible to analyze the major environmental threats, which are possible during the building and operation of a small hydroelectric power plant on the Stryi river in the Dovhe village (Drohobych district, Lviv region). Conclusions. To prevent the impact of the projected SHEPP in the Carpathian region it is necessary to prescribe the mechanism of carrying out the environmental impact assessment, to specify the natural-geographical, hydrological and hydro-ecological restrictions on the construction and operation of the hydroelectric power station. It is also necessary to identify sections of mountain (“wild”) rivers with high values of natural landscapes and prohibit the construction of small hydropower facilities.

Renewable energy has become the most prominent source of energy to reduce carbon emissions around the globe. Undoubtedly, hydro energy is very much clean energy among other sources. In Bangladesh, hydro energy is available only in a specific southern area contributing several hundred megawatts to the national grid. This paper devotes to assessing the capacity and practicability of a hydropower plant to boost the power output by implementing the combined cycle hydropower system. The proposed method has been developed by 1) studying the existing plant based on surveyed data, 2) selecting the site for installing the hydrokinetic turbine, 3) designing with consideration of numerous constraints of inter dependability, and 4) creating a prototype model to ensure the practicability. Preliminary results show that a significant amount of additional electric energy can be generated from the plant with higher efficiency.

The article deals with the process of parameters estimation of the flood zone at the dam break or its destruction, and a scale of possible destruction caused by possible emergencies. Modeling is carried out for the time of approach of the breakthrough wave to a given distance, the height of the breakthrough wave, the time of discharge of the reservoir, the duration of the passage of the wave at a predetermined distance for buildings and structures in the area of shock wave. The example is done for the dam of the Middle Dnieper hydroelectric power station. A technique for modeling a hazardous situation related to the consequences of a breakthrough of the dam at the Middle Dnieper Hydropower Plant has been developed. The prediction and simulation is based on the phenomenological parameters of the Kamyansky reservoir.The simulation of the assessment of the engineering environment for the dam of the Serednyodniprovska hydroelectric power station was carried out using the parameters of flooding of the terrain. Parameters used - the possible maximum depth of flooding, the width of flooding and the rate of water flow at the break of the dam, the time of arrival of the wave front, the crest and tail of the break wave, maximal flow dams, wave heights above water level above domestic flow. As a result, the maximum flooded area was estimated.Based on the use of dam and reservoir characteristics and the use of appropriate formulas for calculating emergency factors and using modeling using ArcGIS, the possible topographic consequences of the breakthrough of the dam in the city Kamianske and the locations of industrial enterprises in its vicinity were obtained. The latter enables rescue services to promptly assess the threat of an emergency in the event of an emergency, to have an idea of the consequences in order to take preemptive measures to prevent the occurrence of an emergency.

Abstract Hydroelectric power stations may affect the population dynamics of mosquitoes and sand flies, a group with impact on public health due to the possibility to transmit pathogens to humans. This work characterized and compared the fauna of mosquitoes and sand flies in a hydroelectric power station and peridomicile areas in the State of Minas Gerais, Brazil. Insect collections were performed in August 2015 at dry season and February 2016 in rainy season. Ten HP light traps were set at each of two sites for three consecutive days in each of two seasons (dry and rainy). Furthermore, collections with Shannon traps were made in each sampling area (hydropower plant and peridomicile area) from 4:00 p.m. being shut down at 8:00 p.m. for two consecutive days in each of two seasons (dry and rainy). In total, 1,222 insects from 13 genera and 27 species were collected. The most plentiful species were respectively Culex declarator (Dyar and Knab, 1906) and Pintomyia pessoai (Coutinho & Barretto, 1940). A high number of insects (78.5%) were collected during the rainy period (P < 0.05). About equitability, statistical significance was observed in the peridomicile area (dry season J = 0.75 and rainy season J = 0.82). The highest values of species diversity were observed in the hydropower plant (H = 2.68) and peridomicile area (H = 2.38) both in the rainy season with statistical significance comparing with dry season. Our results demonstrate that the occurrence of vector species in this region increases the potential risk of transmission of pathogens, especially arbovirus and Leishmania Ross, 1903.

Presently, however, Hydroelectric is a source of power that can prove to be available to all, regardless of conditions such as weather. As history showed, a lot of development, as well as alterations, were made to this efficient supply of energy. Hydropower is a positive alternative energy source that nature provides, therefore, its effective usage is not prohibited. Although there are many disadvantages associated with the design and construction of a hydroelectric power plant, the advantageous features are even more enormous. This paper deals with construction and design aspects for the implementation of the small hydroelectric power station. The main parameters can be collected from the site. Then the turbine type and dimensions can be specified. The generator specifications,which is the main part in the system, for hydro-power stations can be obtained from the determination of turbine output power. These specifications involve mainly the rated power in KVA, the type of system, system frequency, the type of stator winding connection, rated load voltage, rated load current, load power factor, generator speed, method of the system cooling, and the generator type of excitation.

The rapid spread of storm floods over large areas requires flood management throughout the river basin by the creation an innovative system of flood control facilities of various functional purposes distributed in the area. The central part of the system is the hydro system with hydro power plant. In addition, the flood control facilities on the side tributaries with self-regulating reservoir are included in the system. To assess the effect of controlling extreme water discharges by flood control facilities, it is necessary to develop special mathematical models reflecting the specifics of their operation. Unified mathematical models of the operation modes of a hydro complex with hydroelectric power station and flood control facility are created. They are implemented in a computer program that provides the ability to determine the main parameters and operating characteristics of hydro systems when performing multivariate calculations in a wide range of initial data. This makes possible specifying the parameters and operation modes of each hydro system with the current economic and environmental requirements, to assess the energy-economic and environmental consequences in the operation of the system of flood control facilities distributed in the area. The article analyses the results of the extreme water discharge’s regulation by the hydro system on the main river and flood control facilities on the side tributaries, considering environmental requirements.
