Katse Dam
The Katse Dam, a concrete arch dam on the Malibamat'so River in Lesotho, is Africa's second largest double-curvature arch dam. (The Tekezé Dam, completed in early 2009, is now Africa's largest double curvature dam). The dam is part of the Lesotho Highlands Water Project, which will eventually include five large dams in remote rural areas. The dam is just below the confluence of the Bokong River, which forms the western arm of the Katse reservoir. The potential of the project was identified by the South African civil engineer Ninham Shand in 1953 as a possible means to supplement the water supply of South Africa's industrial heartland in the Witwatersrand. The World Bank arranged a treaty between the governments of South Africa and Lesotho, allowing the project to proceed. Construction The dam was built by a consortium of Bouygues, Concor, Group 5, Hochtief, Impregilo, Kier Group and Sterling International. The dam was completed in 1996 and the reservoir filled with water b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Malibamat'so River
The Malibamat'so River is a river in northern Lesotho. Its origin is near to the South African border, where it drains the eastern slopes of the Maloti Range. It flows southwards past the village of Lejone, and eventually joins the Senqu River northeast of Mohlanapeng. The Malibamat'so forms the northern arm of the Katse Dam reservoir, a part of the Lesotho Highlands Water Project The Lesotho Highlands Water Project (LHWP) is an ongoing water supply project with a hydropower component, developed in partnership between the governments of Lesotho and South Africa.

Induced Seismicity
Induced seismicity is typically minor earthquakes and tremors that are caused by human activity that alters the stresses and strains on Earth's crust. Most induced seismicity is of a low magnitude. A few sites regularly have larger quakes, such as The Geysers geothermal plant in California which averaged two M4 events and 15 M3 events every year from 2004 to 2009. The Human-Induced Earthquake Database (''HiQuake'') documents all reported cases of induced seismicity proposed on scientific grounds and is the most complete compilation of its kind. Results of ongoing multi-year research on induced earthquakes by the United States Geological Survey (USGS) published in 2015 suggested that most of the significant earthquakes in Oklahoma, such as the 1952 magnitude 5.7 El Reno earthquake may have been induced by deep injection of waste water by the oil industry. A huge number of seismic events in fracking states like Oklahoma caused by increasing the volume of injection. "Earthquake rat ...

Intake Tower
An intake tower or outlet tower is a vertical tubular structure with one or more openings used for capturing water from reservoirs and conveying it further to a hydroelectric or water-treatment plant. Unlike spillways, intake towers are intended for the reservoir's regular operation, conveying clean, debris-free water for further use. Construction An intake tower is typically made from reinforced concrete, with foundations laid in the river or lake bed. It has at least one water-collecting opening at the top, and may have additional openings along its height, depending on the purpose: towers for hydroelectric plants typically have only one inlet, while those in water-processing plants have multiple draw-off inlets. Near the bottom of the tower, depending on the dam construction and plant location, a horizontal or slanted outlet conduit takes the water from the tower into the plant. The most convenient location for an intake tower is in the proximity of the processing plant. In ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Orange River
The Orange River (from Afrikaans/Dutch: ''Oranjerivier'') is a river in Southern Africa. It is the longest river in South Africa. With a total length of , the Orange River Basin extends from Lesotho into South Africa and Namibia to the north. It rises in the Drakensberg mountains in Lesotho, flowing westwards through South Africa to the Atlantic Ocean. The river forms part of the international borders between South Africa and Lesotho and between South Africa and Namibia, as well as several provincial borders within South Africa. Except for Upington, it does not pass through any major cities. The Orange River plays an important role in the South African economy by providing water for irrigation and hydroelectric power. The river was named the Orange River in honour of the Dutch ruling family, the House of Orange, by the Dutch explorer Robert Jacob Gordon. Other names include simply the word for river, in Khoekhoegowab orthography written as !Garib, which is rendered in Afrikaa ...

Maseru
Maseru is the capital and largest city of Lesotho. It is also the capital of the Maseru District. Located on the Caledon River, Maseru lies directly on the Lesotho–South Africa border. Maseru had a population of 330,760 in the 2016 census. The city was established as a police camp and assigned as the capital after the country became a British protectorate in 1869. When the country achieved independence in 1966, Maseru retained its status as capital. The name of the city is a Sesotho word meaning "red sandstones". History Maseru was founded by the British as a small police camp in 1869, following the conclusion of the Free State–Basotho Wars when Basutoland became a British protectorate. Maseru is located at the edge of the "conquered territories" relinquished to the Orange Free State (now the Free State province of South Africa) as part of the peace terms. It was located west of Basotho King Moshoeshoe I's stronghold of Thaba Bosiu, the previous ''de facto'' capital. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caledon River
The Caledon River ( st, Mohokare) is a major river located in central South Africa. Its total length is , rising in the Drakensberg Mountains on the Lesotho border, flowing southwestward and then westward before joining the Orange River near Bethulie in the southern Free State. Geography The origin of the River Caledon is in the former bantustan of QwaQwa, near the border with Lesotho, southwest of Witsieshoek. It then flows south-west bordering Lesotho's capital city, Maseru. It forms the border between South Africa and Lesotho before entering South Africa's Free State province (north of Wepener). It then flows westward before joining the Orange River near Bethulie in southern Free State, just before flowing into the Gariep Dam. Its total length is about , and its valley experiences great temperature swings. The land in the wedge between these two rivers forms the 22,000-ha Tussen-die-Riviere Nature Reserve. River The river is the primary source of water for Maseru, the capita ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royalties
A royalty payment is a payment made by one party to another that owns a particular asset, for the right to ongoing use of that asset. Royalties are typically agreed upon as a percentage of gross or net revenues derived from the use of an asset or a fixed price per unit sold of an item of such, but there are also other modes and metrics of compensation.Guidelines for Evaluation of Transfer of Technology Agreements, United Nations, New York, 1979 A royalty interest is the right to collect a stream of future royalty payments. A license agreement defines the terms under which a resource or property are licensed by one party to another, either without restriction or subject to a limitation on term, business or geographic territory, type of product, etc. License agreements can be regulated, particularly where a government is the resource owner, or they can be private contracts that follow a general structure. However, certain types of franchise agreements have comparable provisions. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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.

Tunnel
A tunnel is an underground passageway, dug through surrounding soil, earth or rock, and enclosed except for the entrance and exit, commonly at each end. A pipeline is not a tunnel, though some recent tunnels have used immersed tube construction techniques rather than traditional tunnel boring methods. A tunnel may be for foot or vehicular road traffic, for rail traffic, or for a canal. The central portions of a rapid transit network are usually in the tunnel. Some tunnels are used as sewers or aqueducts to supply water for consumption or for hydroelectric stations. Utility tunnels are used for routing steam, chilled water, electrical power or telecommunication cables, as well as connecting buildings for convenient passage of people and equipment. Secret tunnels are built for military purposes, or by civilians for smuggling of weapons, contraband, or people. Special tunnels, such as wildlife crossings, are built to allow wildlife to cross human-made barriers safely. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
