Xingó Dam
The Xingó Dam is a concrete face rock-fill dam on the São Francisco River on the border of Alagoas and Sergipe, near Piranhas, Brazil. The dam was built for navigation, water supply and hydroelectric power generation as it supports a power station. It was constructed between 1987 and 1994 and the last of its generators was commissioned in 1997. In Portuguese, the dam is called the Usina Hidrelétrica de Xingó. Construction Studies for the Xingó Dam were done in the 1950s and contracts for construction were not awarded until 1982. Construction on the dam began in March 1987 but stopped in September 1988 because a debt crisis stalled funding. Construction commenced again in 1990 and by 1994, the dam was complete. On June 10, 1994, the dam began to impound the river as its reservoir began to fill. On November 15 of that year, the reservoir reached its maximum level of . The power station's first generator was commissioned in December 1994, the next two in 1995, two more in 1996 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
São Francisco River
The São Francisco River (, ) is a large Rivers of Brazil, river in Brazil. With a length of , it is the longest river that runs entirely in Brazilian territory, and the fourth longest in South America and overall in Brazil (after the Amazon River, Amazon, the Paraná River, Paraná and the Madeira River, Madeira). It used to be known as the by the indigenous people before colonisation, and is today also known as . The São Francisco originates in the Serra da Canastra, Canastra mountain range in the central-western part of the state of Minas Gerais. It runs generally north in the states of Minas Gerais and Bahia, behind the coastal range, draining an area of over , before turning east to form the border between Bahia on the right bank and the states of Pernambuco and Alagoas on the left one. After that, it ends on the boundaries between the states of Alagoas and Sergipe and washes into the Atlantic Ocean. In addition to the five states which the São Francisco directly traver ...

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] |
Dams In Alagoas
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 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. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dams, ...

Energy Policy Of Brazil
Brazil is the 7th largest energy consumer in the world and the largest in South America. At the same time, it is an important oil and gas producer in the region and the world's second largest ethanol fuel producer. The government agencies responsible for energy policy are the Ministry of Mines and Energy (MME), the National Council for Energy Policy (CNPE), the National Agency of Petroleum, Natural Gas and Biofuels (ANP) and the National Agency of Electricity (ANEEL). OECD/ IEA. World Energy Outlook 2006. State-owned companies Petrobras and Eletrobras are the major players in Brazil's energy sector, as well as Latin America's. Overview In 2020, Brazil derived roughly one third of its total energy supply from oil, and another third from biofuels. Access to electricity across the country is almost universal, making Brazil’s energy sector one of the least carbon-intensive in the world.

Siemens
Siemens AG ( ) is a German multinational technology conglomerate. It is focused on industrial automation, building automation, rail transport and health technology. Siemens is the largest engineering company in Europe, and holds the position of global market leader in industrial automation and industrial software. The origins of the conglomerate can be traced back to 1847 to the ''Telegraphen Bau-Anstalt von Siemens & Halske'' established in Berlin by Werner von Siemens and Johann Georg Halske. In 1966, the present-day corporation emerged from the merger of three companies: Siemens & Halske, Siemens-Schuckert, and Siemens-Reiniger-Werke. Today headquartered in Munich and Berlin, Siemens and its subsidiaries employ approximately 320,000 people worldwide and reported a global revenue of around €78 billion in 2023.

Paulo Afonso Hydroelectric Complex
The Paulo Afonso Hydroelectric Complex (Complexo Hidrelétrico de Paulo Afonso), also known as the Paulo Afonso Complex, is a system of three dams and five hydroelectric power plants on the São Francisco River near the city of Paulo Afonso in Bahia, Brazil. The complex exploits an natural gap on the river, known as the Paulo Afonso Falls. Constructed in succession between 1948 and 1979, the dams support the Paulo Afonso I, II, III, IV and Apollonius Sales (Moxotó) power plants which contain a total of 23 generators with an installed capacity of . PA I was the first large power plant constructed in Brazil and the complex constitutes the densest area of dams in Brazil. The complex provides electricity to areas in northeastern Brazil and is the main tourist attraction in the region. Background and history On January 23, 1913, the 1.1 MW Angiquinho Hydroelectric Plant, built by industrialist Delmiro Gouveia, was the first use of the Paulo Afonso Falls for power production and ...

Floodgate
Floodgates, also called stop gates, are adjustable gates used to control water flow in flood barriers, reservoir, river, stream, or levee systems. They may be designed to set spillway crest heights in dams, to adjust flow rates in sluices and canals, or they may be designed to stop water flow entirely as part of a levee or storm surge system. Since most of these devices operate by controlling the water surface elevation being stored or routed, they are also known as crest gates. In the case of flood bypass systems, floodgates sometimes are also used to lower the water levels in a main river or canal channels by allowing more water to flow into a flood bypass or detention basin when the main river or canal is approaching a flood stage. Types Valves Valves used in floodgate applications have a variety of design requirements and are usually located at the base of dams. Often, the most important requirement (besides regulating flow) is energy dissipation. Since water is very ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
