Luiz Barreto Dam
The Luiz Carlos Barreto de Carvalho Dam is an embankment dam on the Grande River near Fronteira in São Paulo, Brazil. The dam serves an associated hydroelectric power plant with a installed capacity. Background Owned and maintained by Eletrobrás Furnas, they completed studies for the dam in 1962. Construction began in 1963 and was complete in March 1969 when the first generator went online. The dam and power plant were also inaugurated that year. Because of the Furnas Dam upstream, the water level in the reservoir is operated at similar levels year round. Furnas is currently planning to renovate and modernize the dam and power plant. Specifications The Luiz Barreto Dam is a long and high earth-fill embankment dam. The total structural volume of materials for the dam is . The dam's spillway contains six floodgates that are wide and high each. In total, the spillway has a discharge capacity. Reservoir The reservoir created by the dam has a surface area of and capacity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rio Grande (Paraná River)
The Rio Grande ( and ), known in Mexico as the Río Bravo del Norte or simply the Río Bravo, is one of the principal rivers (along with the Colorado River) in the southwestern United States and in northern Mexico. The length of the Rio Grande is . It originates in south-central Colorado, in the United States, and flows to the Gulf of Mexico. The Rio Grande drainage basin (watershed) has an area of ; however, the endorheic basins that are adjacent to and within the greater drainage basin of the Rio Grande increase the total drainage-basin area to . The Rio Grande with its fertile valley, along with its tributaries, is a vital watersource for seven US and Mexican states, and flows primarily through arid and semi-arid lands. After traversing the length of New Mexico, the Rio Grande becomes the Mexico–United States border, between the U.S. state of Texas and the northern Mexican states of Chihuahua and Coahuila, Nuevo León and Tamaulipas; a short segment of the Rio Gr ...

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] |
Dams In São Paulo (state)
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. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Peixotos Dam
Peixoto Dam, also known as Mascarenhas de Moraes Hydroelectric Plant, is a hydroelectric dam on the Grande River in the state of Minas Gerais, Brazil, about west of Delfinópolis. Studies for a dam at the Peixoto site were first carried out in 1947 by the Companhia Paulista de Força e Luz, which obtained rights to develop the site in 1950. The dam was built between 1952 and 1957 with help from the United States and the dam dedicated on April 30, 1957 by Brazilian President Juscelino Kubitschek. The first two Francis turbine-generators came online in 1957, and eight more were installed by 1968, bringing the plant to its full capacity of . Since 1973, the dam and hydroelectric power plant have been operated by Eletrobras Furnas. Peixoto was the first of a cascade of nine dams to be built on the Grande River. The dam consists of a central concrete arch section flanked by gravity wings, totaling high and long, impounding the long Represa de Peixoto (Peixoto Reservoir), with ...

Jaguara Dam
The Jaguara Dam is an embankment dam on the Grande River about north of Rifaina, Brazil. The dam is on the border of Conquista municipality in the state of Minas Gerais to the north and Rifaina municipality in the state of São Paulo to the south. It was constructed between 1966 and 1971 for the purpose of hydroelectric power generation. The power station at the dam has an installed capacity of and is owned by CEMIG.

Electrical Generator
In electricity generation, a generator is a device that converts motive power (mechanical energy) or fuel-based power (chemical energy) into electric power for use in an external circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. Generators provide nearly all of the power for electric power grids. In addition to electromechanical designs, photovoltaic and fuel cell powered generators utilize solar power and hydrogen-based fuels, respectively, to generate electrical output. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors and generators have many similarities. Many motors can be mechanically driven to generate electricity; frequently they make acceptable manual generators. Terminology Electromagnetic ...

Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum.

Spillway
A spillway is a structure used to provide the controlled release of water downstream from a dam or levee, typically into the riverbed of the dammed river itself. In the United Kingdom, they may be known as overflow channels. Spillways ensure that water does not damage parts of the structure not designed to convey water. Spillways can include floodgates and fuse plugs to regulate water flow and reservoir level. Such features enable a spillway to regulate downstream flow—by releasing water in a controlled manner before the reservoir is full, operators can prevent an unacceptably large release later. Other uses of the term "spillway" include bypasses of dams and outlets of channels used during high water, and outlet channels carved through natural dams such as moraines. Water normally flows over a spillway only during flood periods, when the reservoir has reached its capacity and water continues entering faster than it can be released. In contrast, an intake tower is a structure ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
