Cachoeira Do Cai Dam
The Cachoeira do Cai Dam ( pt, Barragem de Cachoeira do Cai}) is a planned hydroelectric dam on the Jamanxim River in the state of Pará, Brazil, with a capacity of . Location The Cachoeira do Cai Dam is proposed to be built on the Jamanxim River in the state of Pará, in the Tapajós river basin. It would adjoin the Sawré Muybu Indigenous Territory, which lies between the Jamanxim and the Tapajós in the region above the point where the two rivers converge.

Jamanxim River
The Jamanxim River is a river of Pará state in north-central Brazil. Originating in the Serra do Cachimbo, it is a tributary of the Tapajós, into which it flows a few kilometers upstream from Itaituba. Course The river flows through the Tapajós-Xingu moist forests ecoregion. It flows through the Itaituba I National Forest, a sustainable use conservation area established in 1998. The river basin also contains part of the Rio Novo National Park, a conservation unit created in 2006. Hydroelectric potential Its hydroelectric potential, along with that of the Tapajós, was assessed by Eletronorte (Centrais Elétricas do Norte do Brasil S.A.), the regional power authority, identifying nine potential dam sites, including four along the Jamanxim. at Cachoeira dos Patos, (estimated at 28 MW); Cachoeira do Caí, (estimated at 802 MW); at Jardim do Ouro and at Jamanxim (estimated at 881 MW). If all were constructed, these dams would flood a total of 103,700 ha, including 33,216 ha o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chacorão Dam
The Chacorão Dam (or Chocorão Dam, pt, Barragem de Chacorão) is a proposed dam on the Tapajós river in the state of Pará, Brazil. It would flood a section of rapids in the river, making them navigable by barges carrying soybeans to ports on the Amazon River. The dam would include locks for the barges and a hydroelectric power plant. It is controversial since it would flood a large area of an indigenous territory. Location The proposed Chacorão Dam would be built on the Tapajós river in the state of Pará. The hydroelectric power plant would be part of the proposed Tapajós hydroelectric complex on the Tapajos and Jamanxim rivers. Others are the São Luiz do Tapajós (6,133 MW), Jatobá (2,338 MW), Cachoeira dos Patos (528 MW), Jamanxim (881 MW) and Cachoeira do Cai (802 MW) plants, all under study, as well as the less advanced proposal for the Jardim do Ouro (227 MW).

Dams In Pará
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] |
Hydroelectric Power Stations In Brazil
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.

Methane Emissions
Increasing methane emissions are a major contributor to the rising concentration of greenhouse gases in Earth's atmosphere, and are responsible for up to one-third of near-term global heating. During 2019, about 60% (360 million tons) of methane released globally was from human activities, while natural sources contributed about 40% (230 million tons). Reducing methane emissions by capturing and utilizing the gas can produce simultaneous environmental and economic benefits. Since the Industrial Revolution, methane concentrations in the atmosphere have more than doubled, and about 20 percent of the warming the planet has experienced can be attributed to the gas. About one-third (33%) of anthropogenic emissions are from gas release during the extraction and delivery of fossil fuels; mostly due to gas venting and gas leaks from both active fossil fuel infrastructure and orphan wells. Russia is the world's top methane emitter from oil and gas. Animal agriculture is a similarly lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

There are some airstrips in and around the forest. Tributaries of the Tapajos include the Cururu, das Tropas, Cupari and Jamanxim. The Jamanxim, which rises in the Serra do Cachimbo in the extreme south of the state, has fast-flowing passages and areas where it sprawls into backwaters, making travel by large boats difficult along most of its length. Its main tributaries are th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
