Nangbeto Dam
The Nangbeto Dam is an embankment dam on the Mono River in the Plateaux Region of Togo. It was constructed between 1984 and 1987 for the purpose of providing hydroelectric power to both Togo and Benin as well as creating fisheries and supplying water for irrigation. The dam's power station was commissioned in June 1987. The project was financed by the World Bank and African Development Bank The African Development Bank Group (AfDB) or (BAD) is a multilateral development finance institution headquartered in Abidjan, Ivory Coast, since September 2014. The AfDB is a financial provider to African governments and private companies ... at a cost of US$98.22 million. The objectives of the dam were to satisfy the medium-term requirements of Benin and Togo for power, and to provide a large water reserve, amounting to 1.7 billion cubic metres. It was expected that 1000 to 1500 tonnes of fish would be produced each year and that 43,000 hectares of land would be irrigated. Evalua ...

Togo
Togo (), officially the Togolese Republic (french: République togolaise), is a country in West Africa. It is bordered by Ghana to the west, Benin to the east and Burkina Faso to the north. It extends south to the Gulf of Guinea, where its capital, Lomé, is located. It covers about with a population of approximately 8 million, and has a width of less than between Ghana and its eastern neighbor Benin. From the 11th to the 16th century, tribes entered the region from various directions. From the 16th century to the 18th century, the coastal region was a trading center for Europeans to purchase slaves, earning Togo and the surrounding region the name "The Slave Coast". In 1884, Germany declared a region including a protectorate called Togoland. After World War I, rule over Togo was transferred to France. Togo gained its independence from France in 1960. In 1967, Gnassingbé Eyadéma led a successful military coup d'état, after which he became president of an anti-communist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kaplan-type
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low- head applications which was not possible with Francis turbines. The head ranges from and the output ranges from 5 to 200 MW. Runner diameters are between . Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm ( Albeni Falls Dam) to 450 rpm. Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Development Viktor Kaplan, living in Brünn, Austria-Hungary (now Brno, Czechia), obtained his first patent for an adjustable blade propeller turbine in 1912. ...

Embankment Dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance. Types Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam. The core can be of clay, concrete, or asphalt concrete. This type of dam is a good choice for sites w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mono River
The Mono River is the major river of eastern Togo. Approximately long, and draining a basin of about , it rises between the town of Sokodé and the border with Benin, and flows south. Along the southern portion of the river towards its mouth, it forms the international boundary between Togo and Benin. The river drains into the Bight of Benin through an extensive system of brackish water lagoons and lakes, including Lake Togo. Only the part of the river nearest its mouth is navigable. Most of the river's basin on the upper tableland is cultivated for maize, yams, rice, cotton and cassava. The river is dammed from its mouth by the Nangbeto Dam, a partnership between Benin and Togo completed in 1987. Studies have reported economic benefits from the dam, including tourism and fishing in the lake behind it. The dam's construction displaced between 7,600 and 10,000 people, however, and studies indicate that it has substantially modified the ecology of the lagoon system at the riv ...

Hydroelectric
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.

World Bank
The World Bank is an international financial institution that provides loans and grants to the governments of low- and middle-income countries for the purpose of pursuing capital projects. The World Bank is the collective name for the International Bank for Reconstruction and Development (IBRD) and International Development Association (IDA), two of five international organizations owned by the World Bank Group. It was established along with the International Monetary Fund at the 1944 Bretton Woods Conference. After a slow start, its first loan was to France in 1947. In the 1970s, it focused on loans to developing world countries, shifting away from that mission in the 1980s. For the last 30 years, it has included NGOs and environmental groups in its loan portfolio. Its loan strategy is influenced by the Sustainable Development Goals as well as environmental and social safeguards. , the World Bank is run by a president and 25 executive directors, as well as 29 various v ...

Dams In Togo
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] |

Energy Infrastructure Completed In 1987
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 ...
