Balbina Dam
The Balbina Dam ( pt, Usina Hidrelétrica de Balbina) is a hydroelectric dam and power station on the Uatumã River in the Amazon Rainforest, Brazil. The location is under the municipality of Presidente Figueiredo jurisdiction, in the state of Amazonas. Structure The Balbina Dam was built from 1985 to 1989 and is managed by Manaus Energia, under the Eletronorte system. The first of five generators began operating in February 1989. The dam has an installed capacity of and floods a area. Controversy The dam was established to provide a renewable electricity supply to the city of Manaus but was considered by locals a controversial project from the start, due to the loss of forest and displacement of tribal homes grounds. About of land formerly occupied by the Waimiri-Atroari was removed from the Waimiri Atroari Indigenous Territory and flooded. The dam was also criticized for its expensive construction and maintenance costs. As a result of the methane released from its vast r ...

Uatumã River
The Uatumã River (sometimes spelled Uatamã) is a river flowing through the state of Amazonas in Brazil. It is a northern tributary of the Amazon River, and known for its extensive peacock bass population. It is a blackwater river. The river flows through the Uatuma-Trombetas moist forests ecoregion. During the wet season starting in December, water levels can rise some 25 to 40 feet. Water levels have been strongly affected by the building of the controversial Balbina Dam on the river in the mid to late 1980s to generate electricity. The hydroelectric dam generates an average of 112.2 MW of electricity from the river system and floods a total of 2360 km2 of rainforest around the Uatumã river. From the point where the river emerges from the dam it defines the east boundary of the Caverna do Maroaga Environmental Protection Area, established in 1990. The Uatumã Biological Reserve established in 1990 is a nature reserve around the river in the municipalities of São ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waimiri Atroari Indigenous Territory
The Waimiri Atroari Indigenous Territory ( pt, Terra Indígena Waimiri Atroari) is an indigenous territory in the states of Amazonas and Roraima, Brazil. There has been a long history of violent conflict between the indigenous Waimiri-Atroari people and newcomers from other parts of Brazil. Since the 1960s there have been many efforts to "civilise" the Waimiri-Atroari to avoid problems with the BR-174 highway, which cuts across the territory, and with tin mines and the huge Balbina Dam. The territory is now considerably smaller, but there have been improvements in living standards. Location The territory has an area of , divided between the states of Amazonas and Roraima. It lies to the northwest of the massive reservoir of the Balbina Dam and to the east of the Rio Negro. The reserve contains the basins of the Jauaperi and Camanaú rivers and their tributaries, the Alalaú, Curiaú, Pardo and Santo Antonio do Abonari rivers.

Energy Infrastructure Completed In 1989
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 that has mass whe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams Completed In 1989
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 used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
