Emborcação Dam
The Emborcação Dam, also known as Theodomiro Santiago, is an embankment dam on the Paranaíba River near Araguari in Minas Gerais, Brazil. It was constructed for hydroelectric power production and flood control. Background Feasibility studies for the dam occurred in 1971 and in June 1977, construction on the dam began. In August 1981, the dam began to impound the reservoir and the first generator became operation in 1982, the last in 1983. The dam was inaugurated in 1983 by Brazilian president João Batista Figueiredo. Dam The dam is long and tall and withholds a reservoir with a capacity of and surface area of .

Paranaíba River
The Paranaíba River is a Brazilian river whose source lies in the state of Minas Gerais in the Mata da Corda mountains, municipality of Rio Paranaíba, at an altitude of 1,148 meters; on the other face of this mountain chain are the sources of the Abaeté river, tributary of the São Francisco River. The length of the river is approximately up to the junction with the Grande River, both of which then form the Paraná River, at the point that marks the borders of the states of São Paulo, Minas Gerais, and Mato Grosso do Sul. Geography The main tributaries of the Paranaíba are the São Marcos, the Corumbá, the Meia Ponte, and the Bois. Major dams on its course are the Barragem de Emborcação, Barragem Itumbiara and Barragem de São Simão. Cachoeira Dourada near Itumbiara is one of the most important hydroelectric power stations in Brazil, providing energy to Goiânia and Brasília. The Paranaíba is navigable only in the artificial lake of Ilha Solteira with an exte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Brazil
Brazil ( pt, Brasil; ), officially the Federative Republic of Brazil (Portuguese: ), is the largest country in both South America and Latin America. At and with over 217 million people, Brazil is the world's fifth-largest country by area and the seventh most populous. Its capital is Brasília, and its most populous city is São Paulo. The federation is composed of the union of the 26 states and the Federal District. It is the largest country to have Portuguese as an official language and the only one in the Americas; one of the most multicultural and ethnically diverse nations, due to over a century of mass immigration from around the world; and the most populous Roman Catholic-majority country. Bounded by the Atlantic Ocean on the east, Brazil has a coastline of . It borders all other countries and territories in South America except Ecuador and Chile and covers roughly half of the continent's land area. Its Amazon basin includes a vast tropical forest, ho ...

Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines Radial turbine, radial and Axial flow turbine, axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the Hydraulic head, head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm.

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 wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric
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 sources combined and also more than nuclear power. Hydropower can provide large amounts of 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, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Flood Control
Flood control methods are used to reduce or prevent the detrimental effects of flood waters."Flood Control", MSN Encarta, 2008 (see below: Further reading). Flood relief methods are used to reduce the effects of flood waters or high water levels. Flooding can be caused by a mix of both natural processes, such as extreme weather upstream, and human changes to waterbodies and runoff. Though building hard infrastructure to prevent flooding, such as flood walls, can be effective at managing flooding, increased best practice within landscape engineering is to rely more on soft infrastructure and natural systems, such as marshes and flood plains, for handling the increase in water. For flooding on coasts, coastal management practices have to not only handle changes water flow, but also natural processes like tides. Flood control and relief is a particularly important part of climate change adaptation and climate resilience, both sea level rise and changes in the weather ...

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 electrical circuit, circuit. Sources of mechanical energy include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand crank (mechanism), 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 genera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
