Jupiá Dam
The Engineer Souza Dias Dam, formerly known as the Jupiá Dam, is an embankment dam on the Paraná River near Três Lagoas in Mato Grosso do Sul, Brazil. It was constructed for hydroelectric power production, flood control and navigation. Studies on the dam and power plant began in 1951 which recommended the dam along with the Ilha Solteira Dam. The dam was inaugurated in 1968 and its generators were commissioned between 1969 and 1974. Dam and reservoir The Souza Dias Dam is a high and long combination concrete gravity and embankment dam. The concrete power plant, navigation lock and spillway section of the dam measures long while the earth-fill embankments flanking the concrete section measure long on the right and long on the left. The reservoir created by the dam has a capacity of which is active or "useful" storage. The reservoir has a catchment area of and surface area of . The dam's spillway contains 37 floodgates, each with a discharge capacity for a total discharge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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] |
Embankment Dams
Embankment may refer to: Geology and geography * A levee, an artificial bank raised above the immediately surrounding land to redirect or prevent flooding by a river, lake or sea * Embankment (earthworks), a raised bank to carry a road, railway, or canal across a low-lying or wet area * Embankment dam, a dam made of mounded earth and rock * Land reclamation along river banks, usually marked by roads and walkways running along it, parallel to the river, as in: ** The Thames Embankment along the north side of the Thames River in London, England *** The Victoria Embankment contained within the Thames Embankments *** The Chelsea Embankment contained within the Thames Embankment ** The Albert Embankment Albert Embankment is part of the river bank on the south side of the River Thames in Central London. It stretches approximately one mile (1.6 km) northward from Vauxhall Bridge to Westminster Bridge, and is located in the London Borough ... along the south side of th ...

Dams On The Paraná River
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, drinking water, human consumption, Industrial water, 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 Dike (construction), 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 (Jorda ...

Electrical Generator
In electricity generation, a generator, also called an ''electric generator'', ''electrical generator'', and ''electromagnetic generator'' is an electromechanical device that converts mechanical energy to electrical energy for use in an external circuit. In most generators which are rotating machines, a source of kinetic power rotates the generator's shaft, and the generator produces an electric current at its output terminals which flows through an external circuit, powering electrical loads. Sources of mechanical energy used to drive generators include steam turbines, gas turbines, water turbines, internal combustion engines, wind turbines and even hand cranks. Generators produce nearly all of the electric power for worldwide electric power grids. The first electromagnetic generator, the Faraday disk, was invented in 1831 by British scientist Michael Faraday. The reverse conversion of electrical energy into mechanical energy is done by an electric motor, and motors a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tietê River
The Tietê River ( ) is a Brazilian river in the state of São Paulo. The first known use of the name Tietê was on a map published in 1748 by d’Anville. The name means "truthful river", or "truthful waters”, in Tupi. The Tietê River is a historically significant and economically important river, which stretches 450 kilometers and allows for navigation of barges carrying various goods. Pollution of the Tietê River began subtly in the 1920s, but it has worsened significantly over time. In September 2010, National Geographic identified the river as the most polluted in Brazil. Despite efforts to clean up the river, it still suffers from pollution and environmental degradation, and some species are threatened, or possibly extinct. Source The headwaters are in the Serra do Mar, to the east of São Paulo.

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] |
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 ...

Navigation Lock
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a chamber in a permanently fixed position in which the water level can be varied. (In a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls.) Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Over time, more and larger locks have been used in canals to allow a more direct route to be taken. History Ancient Egypt In Ancient Egypt, the river-locks was probably part of the Canal of the Pharaohs: Ptolemy II is credited by some for being the first to solve the problem of keeping the Nile free of salt water when his engineers invented the lock around 274/273 BC. Ancient China During 960–1279 CE, the natural extension of the flash lock, o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
