Hydroelectric Power Plant Project Research Articles

Omsk Hydroelectric Power Plant Project in Economic History of Region in 1930s—1980s.

The article is dedicated to the unrealized project of the Omsk Hydroelectric Power Station, developed in the 1930s, then postponed and subsequently reintroduced for discussion in the 1980s. The sources used for this research include materials from the Historical Archive of the Omsk Region and the Russian State Archive of Economy. Both domestic and foreign historiography on the economic development of Western Siberia do not mention this project, hence this article aims to fill this historiographical gap. It is demonstrated that the project was considered by regional authorities solely as an agricultural facility, which would have allowed for the use of the reservoir for irrigation in the southern districts of the region and improvement of navigational conditions around the city of Omsk. Emphasis is placed on the fact that its implementation could have boosted the industrial development of the Omsk Region. The abandonment of the project in the 1930s largely determined the subsequent development of the region, particularly from an ecological perspective. To meet the energy needs of the city and the region, construction of thermal power plants began, fueled by Ekibastuz coal, which contains a large amount of ash. This, in turn, led to serious air pollution in the Omsk region, which continues to persist to this day.

Anthropic Impact on the Critically Endangered Melanophryniscus admirabilis (Admirable Redbelly Toad): Evidence from the Presence of Multiresistant Enterobacteriaceae.

Melanophryniscus admirabilis is a microendemic and critically endangered toad, known from a single population. This microendemic species inhabits a small fragment of the Atlantic Forest in South Brazil, an area significantly impacted by hydroelectric power plant projects, livestock farming, agricultural activities, biopiracy, and tourism. Given the exclusive and limited population of M. admirabilis, preserving and conserving this species is of utmost importance in Brazil. Research on this species primarily concentrates on its biology, ecology, and ecotoxicology. Currently, there is no knowledge about antimicrobial resistance (AMR) bacteria present in wild M. admirabilis, despite the potential for studying them to provide valuable insights into environmental pollution. To this end, Enterobacteriaceae species (n = 82) obtained from 15 wild M. admirabilis toads were subjected to the standard Kirby-Bauer disk diffusion method to test their AMR. The results showed that Enterobacteriaceae species had the highest antibiotic resistance to IPM (45.1%), CIP (39%), NIT (32.5%), AMP (31.3%), TET (18.3%), and FOX (17%). Of the tested species, 18 (21.9%) species tested were susceptible, 40 (48.8%) were resistant to 1 or 2 different antibiotic classes, and 24 (29.3%) were classified as multidrug-resistant. Overall, our findings suggest that the incidence of AMR in Enterobacteriaceae isolated from wild M. admirabilis is high, indicating environmental stress caused by anthropic pollution in their habit.

Assessing the impact of hydropower projects in Brazil through data envelopment analysis and machine learning

The aim of this study was to assess the environmental impact of hydroelectric power generation projects and classify them according to their scale of environmental impact. To achieve this objective, the combination of Data Envelopment Analysis (DEA) and Artificial Neural Networks (ANN) techniques was applied to 53 hydroelectric power plant projects in the evaluation phase in Brazil. The main results were: a) the proposed index indicates that 7 of the 10 worst hydroelectric projects are of the Large Hydropower Plant (LHP) type; b) the neural model for predicting the environmental impact of hydroelectric projects has an error of less than 0.001; c) the neural model for classifying hydroelectric projects in terms of their environmental impact reached a performance of 99.0% accuracy. In general, this study contributes to the use of a hybrid decision-making approach based on a combination of DEA-ANN for energy policies, in addition to enabling an improvement in the evaluation of hydroelectric generation projects.

Utilization of fuzzy critical path method and fuzzy program evaluation and review technique for building a hydroelectric power station

In this paper, fuzzy critical path method and fuzzy program evaluation and review technique are used to calculate the earliest project completion time for constructing a hydroelectric power plant project. Fuzzy trapezoidal numbers are used to estimate the activity time and determine the range of pessimistic to optimistic variation of time. Furthermore, the minimum and maximum times of project completion duration were calculated by using arithmetic operations and ranking of fuzzy trapezoidal numbers. These hybrid methods are able to deal with the limitations associated with classical critical path method and program evaluation and review technique. The fuzzy techniques were applied to network activities in a manner similar to the classical methods for optimizing the project completion duration, thereby minimizing the cost of the project. Analysis was carried out to determine the critical path through the use of fuzzy critical path method. The fuzzy program evaluation and review technique was also used to determine the probability of completing the project at a scheduled time. These two methods were then compared and the most probable scenarios were analyzed. Finally, it was concluded that fuzzy program evaluation and review technique is better than fuzzy critical path method and more efficient in terms of early project completion time.

An ecological restoration assessment integrating multi-criteria decision analysis with landscape sensitivity analysis for a hydroelectric power plant project: the Tokat-Niksar case

Due to Turkey's reliance on imported electricity, it has been using hydroelectric power plants (HPPs) to cover some of its electrical energy needs since 2011. However, HPP projects, which do not take landscape sensitivity into account, cause the ecological integrity of the basins and the ecosystem structure to deteriorate. This study presents the Tokat-Niksar HPP project field example in Turkey's Central Black Sea region with its steep slopes, rich forest and creek vegetation, protected endemic plants and wildlife, cultural heritage dating back to 3000 BC agricultural activities, and long-established local culture. The study, in fact, aims to develop a landscape restoration plan that considers the sensitivity of landscapes in the HPP project area. For this purpose, a landscape sensitivity analysis consisting of water, habitat, visibility, erosion functions, and multi-criteria decision analysis (MCDA) determining priority of functions conducted with experts were performed. According to the results, the water function was found to have the highest, and the visibility the lowest priority in the ranking. Consequently, 1st, 2nd, 3rd, and 4th-degree sensitive areas with very high, high, and moderate landscape sensitivity were determined by weighted sum function by considering the priority of each landscape function, and accordingly, a five-stage landscape restoration model was developed including soil protection, areas to be protected, erosion control, vegetation screening, and creek reclamation. This study presents a framework for sustainable landscape restoration solutions in the town by combining landscape sensitivity analysis via MCDA.

Towards a pluralist labor geography: Constrained grassroots agency and the socio-spatial fix in Dȇrsim, Turkey

This paper explores the interplay between capital, socio-spatial structure and grassroots agency in the context of the recent trajectories of labor geography. Based on field research conducted in Dȇrsim, Turkey, our analysis unfolds the constraining role of socio-spatial structure in the agency and praxis of grassroots movements and their geography-making and crisis-displacement from below. Through the case study, we propound a concept of socio-spatial fix to explain how this praxis conjoins with and assists capital in both staving off its recurrent crises and reproducing its own logic of accumulation. Our analysis reveals that the socio-spatial fix in Dȇrsim, which is constituted by the grassroots struggle against hydroelectric power plant projects, performs three functions. First, it facilitates the production of capitalist social relations and spaces; second, it strengthens and maintains the existing social order through temporally moderating the province’s chronic problems; and third, it provides legitimacy for the capitalist exploitation of nature, culture and histories. Our research contributes to the emerging pluralist school of labor geography, providing an empirically substantiated insight into how capital reproduces itself via socio-spatial fixes produced by constrained grassroots agency.

The local management and sustainability of swidden farming in the Villages of Bojongsalam and Sukaresmi, Upper Cisokan Watershed, West Java, Indonesia

Choir IR, Iskandar J, Parikesit, Partasasmita R, Husodo T, Kumoro J, Megantara EN. 2018. The local management and sustainability of swidden farming in the Villages of Bojongsalam and Sukaresmi, Upper Cisokan Watershed, West Java, Indonesia. Biodiversitas 19: 1054-1065. In the past, the swidden farming (huma or ladang) system had been predominantly practiced by village people of West Java. Nowadays, however, the huma farming has rarely been practiced by the village people of West Java due to the government policy, and environmental and socioeconomic changes. The local community who reside in the Villages of Bojongsalam and Sukaresmi, the upper stream of Cisokan, West Java, Indonesia, has still practiced both the wet rice field (sawah) and the huma farming in the private land, production forest of a state-owned forest company (Perhutani), and a state-owned electric company (PLN) project land. Recently some areas of the huma land have been used for the project of the Hydroelectric Power Plant of the Upper Cisokan Pumped Storage (UCPS). As a result, the sustainability of huma system of the local people of Bojongsalam and Sukaresmi has been seriously disturbed. The aims of this study were to elucidate the local management of the huma farming systems that are undertaken by local people of Bojongsalam and Sukaresmi Villages, and to analyze the sustainability of the huma farming of local people of Bojongsalam and Sukaresmi Villages as affected by the UCPS Hydroelectric Power Plant project. The qualitative method was used, while several techniques of collecting the primary data, namely observation and in-depth interviews with informants were applied in this study. The results of study showed that the local management of the huma farming has been annually undertaken by the local people of Bojongsalam and Sukaresmi, including deciding the location of huma plot, preparing the land (cutting shrubs and burning vegetation biomass), planting rice (ngaseuk) and other annual crops, weeding (ngored) and providing chemical fertilizers (mupuk), controlling pests, harvesting rice (dibuat), and fallowing land. Based on analysis of the emergent properties of the agroecosystem of huma farming, it can be predicted that productivity, stability, equitability, and sustainability of the huma farming systems of Bojongsalam and Sukaresmi Villages tend to be low in the near future due to the impact of UCPS Hydroelectric Power Plant project.

Reverse Engineering of Turbine Blades Kaplan’s type for Small Hydroelectric Power Station

The paper presents the reverse engineering procedure for the reconstruction of the turbine blades for small hydropower plants. The scaled turbine model of Iron Gate I Hydroelectric Power Station on the Danube river has been used for decades under the same exploitation conditions as a large turbine, to simulate the condition of large blades based on the similarity of physical phenomena. The blades of the scaled model have been selected for the small hydroelectric power plant project. Since the scaled turbine model was manufactured in the early 70’s, the CAD model is not available. The blade in best condition was scanned using an optical scanner. Starting from the STL model, the surface of the blade was redesigned, so that all damages and deformations were corrected.

The water–energy nexus in Chile: a description of the regulatory framework for hydroelectricity

This article offers a general description of hydropower regulations in Chile wherein two sectors that are regulated separately come to meet each other: water (as a natural resource) and electric industry (as an activity). First, the characteristics for pursuing the activity are described together with the manner in which the hydropower plants perform their function as an energy source both in terms of implementation (setting up the plants) as well as in terms of operations (functioning as an energy source). Second, the legal schemes that serve as the institutional foundation and regulatory system for water and energy are laid out. Lastly, specific regulation applicable to developing hydropower is reviewed in terms of both hydroelectric power plant projects (their construction) as well as operations.

Fish fauna in tributaries of the Suiá-Miçú River (upper Xingu river basin), in the Cerrado-Amazon transition zone, eastern state of Mato Grosso, Brazil

Studies on the fish fauna of the Xingu river basin are mainly concentrated in the main channel of the river or its large tributaries, due to requirements all faunal surveys in hydroelectric power plant projects. Our goal was to conduct a survey of the composition of fish fauna in headwater streams (lotic environments) and small reservoirs (artificial lentic environments) built on these streams in the upper Xingu River region. Fish were sampled in the dry period, July 2013, using active sampling methods in a 100 meter-section at each sampling site. We recorded the occurrence of 33 species of five orders and 16 families. Characiformes was the most species-rich order, with 19 species, followed by Siluriformes, Gymnotiformes and Perciformes, with four species each.

The Ombla Hydro-Electric Power Plant Project for Power Utilization of Underground Waters in Karst Aquifer and Conservation of High Quality Freshwater

Energetski potencijal površinskih vodotoka na krškom terenu Dinarida, koji se u širokom pojasu proteže uz hrvatsku obalu, većim je dijelom iskorišten. Međutim, značajni dio voda koje se akumuliraju u krškom podzemlju ovoga velikog prostora, do danas nije adekvatno energetski vrednovan. Na osnovi rezultata opsežnih geoloških, hidrogeoloških, hidroloških, strukturno tektonskih, geofizičkih, geotehničkih i ostalih istraživanja izrađen je projekt HE Ombla čija je posebnost da se koristi vodom podzemnih akumulacija, stvorenih izgradnjom podzemne brane te čiji su svi objekti također smješteni u podzemlju. Izdizanjem vodozahvata iz zone baznog toka u zonu usporenog tečenja eliminiraju se uzroci povremenog onečišćenja, a u budućnosti i trajnijeg zagađenja pitke vode.

AN EARLY COST ESTIMATION MODEL FOR HYDROELECTRIC POWER PLANT PROJECTS USING NEURAL NETWORKS AND MULTIPLE REGRESSION ANALYSIS

Energy is increasingly becoming more important in today’s world, whereas energy sources are drastically decreasing. One of the most valuable energy sources is hydro energy. Because of limited energy sources and excessive energy usage, cost of energy is rising. Among the electricity generation units, hydroelectric power plants are very important, since they are renewable energy sources and they have no fuel cost. To decide whether a hydroelectric power plant investment is feasible or not, project cost and amount of electricity generation of the investment should be precisely estimated. In this paper, fifty four hydroelectric power plant projects are analysed by using multiple regression and artificial neural network tools. As a result, two cost estimation models have been developed to estimate the hydroelectric power plant project cost in early stages of the project.

The Influence of Changes in Lifestyle and Mercury Exposure in Riverine Populations of the Madeira River (Amazon Basin) near a Hydroelectric Project

In the Amazon Basin, naturally occurring methylmercury bioaccumulates in fish, which is a key source of protein consumed by riverine populations. The hydroelectric power-plant project at Santo Antônio Falls allows us to compare the Hg exposure of riverine populations sparsely distributed on both sides of the Madeira river before the area is to be flooded. From 2009 to 2011, we concluded a population survey of the area (N = 2,008; representing circa 80% of community residents) that estimated fish consumption and mercury exposure of riverine populations with different degrees of lifestyle related to fish consumption. Fish samples from the Madeira river (N = 1,615) and 110 species were analyzed for Hg. Hair-Hg was significantly lower (p < 0.001) in less isolated communities near to the capital of Porto Velho (median 2.32 ppm) than in subsistence communities in the Cuniã Lake, 180 km from Porto Velho city (median 6.3 ppm). Fish Hg concentrations ranged from 0.01 to 6.06 µg/g, depending on fish size and feeding behavior. Currently available fish in the Madeira river show a wide variability in Hg concentrations. Despite cultural similarities, riparians showed hair-Hg distribution patterns that reflect changes in fish-eating habits driven by subsistence characteristics.

The Place Of River Type Power Plants In Turkey Hydroelectric Production

In the study, contributions of river type power plants to Turkey’s hydroelectric production is examined. This type of power plants, mostly used on smaller rivers, is expected to be more important in the near future because of increase of national electricity demand. So, working conditions and establishing possibilities of these power plants on Turkey’s rivers are needed to be determined. This study aims to contribute this subject as a geographical point of viev. Evaluation of data, firstly, statistics of EIE, DSI and many other instutions are used. While examining economical and technical point of this subject, the data of Esendurak Hydroelectric Power Plant Project, planned to establish on Tortum river, are used. According to our findings, there is an important hydroelectric potential as a river type power plants on the Mediterranean and Blacksea basins. A twenty percent of Turkey hydroelectric potential can be transformed into production by the help of this type power plants. In spite of this, the rate of production of the 62 river type plants power in hydroelecric production is % 12 and also the rate of in the potential that can be utilized economically is % 2.4. Basically, to increase these proportions with new investmennts is possible. This is also another way of reducing dependence on exterior in energy production and meeting national electric demand which increasing time by time.
