Gouina Hydroelectric Plant
The Gouina Hydroelectric Plant is a run-of-the-river-type hydroelectric installation currently being constructed on Gouina Falls along the Senegal River in Mali. It is located about southeast of Diamou in the Kayes Region. It is the fourth project of the Senegal River Basin Development Authority and its ground-breaking ceremony on 17 December 2013 was attended by the heads of state of each member country. Mauritanian President Mohamed Ould Abdel Aziz laid the foundation stone. Preliminary construction had been suspended due to the 2012 Malian coup d'état and subsequent Northern Mali conflict. The plant is expected to be complete in 2020 and will provide power to Mauritania, Mali and Senegal. The plant will cost US$329 million and the of transmission lines will cost US$65 million. The project is receiving 85 percent of its funding from the Exim Bank of China along with US$1 million from the EU-Africa Infrastructure Trust Fund and US$1.4 million from the International Development ...

Gouina Falls
The Gouina Falls or ''Chutes de Gouina'' are on the Sénégal River in Mali between the towns of Bafoulabé (upstream) and Diamou (downstream) in the Kayes Region, where the river runs north from the Talari Gorges. They have been called the "Niagara falls of Mali". The river is about 500 m wide at this point, and drops 16 m over the falls. The volume of water is 12-13 m3 per second in the dry season, and up to 2430 m3 per second in the rainy season. The government of Mali and Senegal River Basin Development Authority has investigated the possibility of developing the electric power potential of the Senegal River. Downstream on the Félou Falls, a new Félou Hydroelectric Plant was completed in 2014.

Manantali Dam
The Manantali Dam is a multi-purpose dam on the Bafing river in the Senegal River basin, to the south-east of Bafoulabé, in Mali's Kayes Region. History Early planning for the dam began in 1972 when the Organization for the Development of the Senegal River (Organisation pour la mise en valeur du fleuve Sénégal, or OMVS) was set up by Mali, Mauritania and Senegal to develop the agricultural and hydropower potential of the basin. The World Bank declined to fund the dam in 1979, considering it an unreasonable investment. However, financing was secured mainly from Europe and construction on the dam began in 1982. It was completed in 1988, but without the hydropower plant. In 1989 the Mauritania–Senegal Border War stopped all work on the project. A Swiss journalist who visited Manantali in 1988 described the project as a "luxury car without a motor". In 1993 Carl–Dieter Spranger, then Germany's minister for development assistance, called Manantali an "act of economic and enviro ...

Hydroelectric Power Stations In Mali
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.

Run-of-the-river Power Stations
Run-of-river hydroelectricity (ROR) or run-of-the-river hydroelectricity is a type of hydroelectric generation plant whereby little or no water storage is provided. Run-of-the-river power plants may have no water storage at all or a limited amount of storage, in which case the storage reservoir is referred to as pondage. A plant without pondage is subject to seasonal river flows, thus the plant will operate as an intermittent energy source. Conventional hydro uses reservoirs, which regulate water for flood control, dispatchable electrical power, and the provision of fresh water for agriculture. Concept Run-of-the-river, or ROR, hydroelectricity is considered ideal for streams or rivers that can sustain a minimum flow or those regulated by a lake or reservoir upstream. A small dam is usually built to create a headpond ensuring that there is enough water entering the penstock pipes that lead to the turbines, which are at a lower elevation. Projects with pondage, as opposed t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams Under Construction
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] |

Weirs
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water behind ...

Diama Dam
The Diama Dam, sometimes referred to as the Maka–Diama Dam, is a gravity dam on the Senegal River, spanning the border of Senegal and Mauritania. It is located next to the town of Diama, Senegal and about north of Saint-Louis, Senegal. The purpose of the dam is to prevent saltwater intrusion upstream, supply water for the irrigation of about of crops and create a road crossing for the road between St. Louis and Nouakchott in Mauritania. Additionally, a ship lock built within the dam provides for navigation upstream. Plans for the dam were first drawn in 1970 when the riparian states within the Senegal River Basin Development Authority agreed to develop the Senegal River. The Diama Dam was to be constructed in conjunction with the Manantali Dam which was to be located further upstream in Mali. Construction on the Diama Dam began on 15 September 1981 and was completed on 12 August 1986. The Manantali Dam was completed in 1988. The Diama project was funded by a US$149.5 million loa ...

Félou Hydroelectric Plant
The Félou Hydroelectric Plant is a hydroelectric installation at the Félou Falls on the Sénégal River in Mali. It has three water turbines capable of generating 62.3 MW. The current power station replaced an older one built in the 1920s. Construction of the new power station began in October 2009 and was financed by the World Bank. It is the third Senegal River Basin Development Authority project on the river and was completed in 2014. The existing weir was refurbished with the previous height maintained. In 1927, the previous hydroelectric power station was commissioned. It was refurbished in 1992 and had an installed capacity of 600 kW. At maximum output the three 21 MW turbines pass a total of of water. Between August and November the water flowing in the river generally exceeds this value allowing the plant to operate at full capacity and the excess water to pass over the weir. During the dry season (December to July) the electricity generated is reduced to ab ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Head
Hydraulic head or piezometric head is a specific measurement of liquid pressure above a vertical datum., 410 pages. See pp. 43–44., 650 pages. See p. 22. It is usually measured as a liquid surface elevation, expressed in units of length, at the entrance (or bottom) of a piezometer. In an aquifer, it can be calculated from the depth to water in a piezometric well (a specialized water well), and given information of the piezometer's elevation and screen depth. Hydraulic head can similarly be measured in a column of water using a standpipe piezometer by measuring the height of the water surface in the tube relative to a common datum. The hydraulic head can be used to determine a ''hydraulic gradient'' between two or more points. "Head" in fluid dynamics In fluid dynamics, ''head'' is a concept that relates the energy in an incompressible fluid to the height of an equivalent static column of that fluid. From Bernoulli's principle, the total energy at a given point in a fluid i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
