Ney Braga Hydroelectric Plant
The Governor Ney Braga de Barros Hydroelectric Plant, formerly known as Segredo, is a dam and hydroelectric power plant on the Iguazu River near Segredo in Paraná, Brazil. It is the fourth dam upstream of the Iguazu Falls and was constructed between 1987 and 1991 while being inaugurated in 1992. The power station has a capacity and is supplied with water by a concrete face rock-fill embankment dam. It is owned and operated by Copel who renamed it after Ney Braga de Barros, governor of Paraná between 1961–1965 and 1979–1982. It was the first hydroelectric project in Brazil's history to provide an Environmental Impact Assessment. History Construction on the dam began in September 1987 with the diversion of the Iguazu River. The diversion tunnel was long and had a diameter of , it was completed in June 1988. Excavations for the dam's foundation began in September 1988 and was completed in December 1989. Construction was complete in 1992. Ney Braga de Barros Dam ...

Iguazu River
__NOTOC__ The Iguazu River ( pt, Rio Iguaçu, br , es, Río Iguazú} ), also called Rio Iguassu, is a river in Brazil and Argentina. It is an important tributary of the Paraná River. The Iguazu River is long, with a drainage basin of . Course The Iguazu originates in the Serra do Mar coastal mountains of the Brazilian state of Paraná and close to Curitiba. For , to its confluence with the San Antonio River, the Iguazu flows west through Paraná State, Brazil. Downriver from the confluence the Iguazu River forms the boundary between Brazil and Argentina's Misiones Province. Continuing west, the river drops off a plateau, forming Iguazu Falls, which are accessible via the Rainforest Ecological Train. The falls are within national parks in both Brazil, Iguaçu National Park, and Argentina, Iguazú National Park. It empties into the Paraná River at the point where the borders of Argentina, Brazil, and Paraguay join, an area known as the Triple Frontier. Ecology Unlike tropi ...

Dams On The Iguazu River
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.

Hydroelectric Power Stations In Paraná (state)
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable source Renewable energy is energy that is collected from renewable resources that are naturally replenished on a human timescale. It includes sources such as sunlight, wind, the movement of water, and geothermal heat. Although most renewable energy ...s combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Infrastructure Completed In 1992
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object tha ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Roller-compacted Concrete
Roller-compacted concrete (RCC) or rolled concrete (rollcrete) is a special blend of concrete that has essentially the same ingredients as conventional concrete but in different ratios, and increasingly with partial substitution of fly ash for Portland cement. The partial substitution of fly ash for Portland Cement is an important aspect of RCC dam construction because the heat generated by fly ash hydration is significantly less than the heat generated by Portland Cement hydration. This in turn reduces the thermal loads on the dam and reduces the potential for thermal cracking to occur. RCC is a mix of cement/fly ash, water, sand, aggregate and common additives, but contains much less water. The produced mix is drier and essentially has no slump. RCC is placed in a manner similar to paving; the material is delivered by dump trucks or conveyors, spread by small bulldozers or specially modified asphalt pavers, and then compacted by vibratory rollers. In dam construction, roll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Environmental Impact Assessment
Environmental Impact assessment (EIA) is the assessment of the environmental consequences of a plan, policy, program, or actual projects prior to the decision to move forward with the proposed action. In this context, the term "environmental impact assessment" is usually used when applied to actual projects by individuals or companies and the term " strategic environmental assessment" (SEA) applies to policies, plans and programmes most often proposed by organs of state. It is a tool of environmental management forming a part of project approval and decision-making. Environmental assessments may be governed by rules of administrative procedure regarding public participation and documentation of decision making, and may be subject to judicial review. The purpose of the assessment is to ensure that decision makers consider the environmental impacts when deciding whether or not to proceed with a project. The International Association for Impact Assessment (IAIA) defines an enviro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paraná (state)
Paraná () is one of the 26 states of Brazil, in the south of the country, bordered on the north by São Paulo state, on the east by the Atlantic Ocean, on the south by Santa Catarina state and the province of Misiones, Argentina, and on the west by Mato Grosso do Sul and Paraguay, with the Paraná River as its western boundary line. It is subdivided into 399 municipalities, and its capital is the city of Curitiba. Other major cities are Londrina, Maringá, Ponta Grossa, Cascavel, São José dos Pinhais and Foz do Iguaçu. The state is home to 5.4% of the Brazilian population and has 6.2% of the Brazilian GDP. Crossed by the Tropic of Capricorn, Paraná has what is left of the araucaria forest, one of the most important subtropical forests in the world. At the border with Argentina is the National Park of Iguaçu, considered by UNESCO as a World Heritage Site. At only from there, at the border with Paraguay, the largest dam in the world was built, the Hidroelétrica de Itaipu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Embankment Dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance. Types Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam. The core can be of clay, concrete, or asphalt concrete. This type of dam is a good choice for sites wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Iguazu Falls
Iguazú Falls or Iguaçu Falls ( gn, Chororõ Yguasu , es, Cataratas del Iguazú, links=no ; pt, Cataratas do Iguaçu ) are waterfalls of the Iguazu River on the border of the Argentine province of Misiones and the Brazilian state of Paraná. Together, they make up the largest waterfall system in the world. The falls divide the river into the upper and lower Iguazu. The Iguazu River rises near the heart of the city of Curitiba. For most of its course, the river flows through Brazil; however, most of the falls are on the Argentine side. Below its confluence with the San Antonio River, the Iguazu River forms the border between Argentina and Brazil. The name ''Iguazú'' comes from the Guarani or Tupi words "''y''" , meaning "water", and "''ûasú'' ", meaning "big". Legend has it that a deity planned to marry a beautiful woman named Naipí, who fled with her mortal lover Tarobá in a canoe. In a rage, the deity sliced the river, creating the waterfalls and condemning the lovers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
