Rio Grande (Paraná River Tributary)
Rio Grande ( Portuguese for "great river") is a river in south-central Brazil. It rises in the Mantiqueira Mountains in the state of Minas Gerais and descends inland, west-northwestward. Its lower course marks a portion of the Minas Gerais-São Paulo border. At the Mato Grosso do Sul state border, after a course of , it joins the Paranaíba River to form the Upper Paraná River. Major tributaries of the Rio Grande are: * Rio Aiuruoca, whose source is in Itamonte; * Rio das Mortes, whose source lies between Barbacena and Senhora dos Remédios; * Rio Jacaré, whose source is in the Serra do Galba; * Rio Sapucaí, whose source is in the Mantiqueira Mountains in São Paulo; * Rio Pardo, whose source is in Ipuiúna. The basin of the Rio Grande belongs to the Paraná River basin. The basin has a total area of , of which are located within Minas Gerais, which is equivalent to 17.8% of the state territory. The basin of the Rio Grande is responsible for about 67% of all energy ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Rapids
Rapids are sections of a river where the river bed has a relatively steep stream gradient, gradient, causing an increase in water velocity and turbulence. Flow, gradient, constriction, and obstacles are four factors that are needed for a rapid to be created. Physical factors Rapids are hydrology, hydrological features between a ''run'' (a smoothly flowing part of a stream) and a ''waterfall#Types, cascade''. Rapids are characterized by the river becoming shallower with some Rock (geology), rocks exposed above the flow surface. As flowing water splashes over and around the rocks, air bubbles become mixed in with it and portions of the surface acquire a white color, forming what is called "whitewater". Rapids occur where the stream bed, bed material is highly resistant to the erosive power of the stream in comparison with the bed downstream of the rapids. Very young streams flowing across solid rock may be rapids for much of their length. Rapids cause water aeration of the stream ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, 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.

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.

Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...
