Thika River
The Thika River flows through Kiambu County in central Kenya and is a tributary of Tana River. The River forms a psychological boundary between the counties of Murang'a and Kiambu. The Thika River is a significant source of hydroelectric power in Kenya and provides most of the water supply for Nairobi, Kenya's capital and largest city. The name ''Thika'' originates either from the Kikuyu language or from the Maasai language. It may relate to the Kikuyu word ''guthika'', which means ''to bury''. It also resembles the Maasai word ''sika'', which means ''to rub something away from an edge''. Course The Thika River originates in the Aberdare Range. It flows to the Tana River, which empties into the Indian Ocean. A landmark along the river's course is Thika Falls, near the town of Thika. Thika Falls has a drop of about 25 meters in a wilderness area within walking distance of the Blue Post Hotel, which is one of the oldest hotels in Kenya. Ecology During the early twentieth c ...

Blue Post Hotel
Blue is one of the three primary colours in the RYB colour model (traditional colour theory), as well as in the RGB (additive) colour model. It lies between violet and cyan on the spectrum of visible light. The eye perceives blue when observing light with a dominant wavelength between approximately 450 and 495 nanometres. Most blues contain a slight mixture of other colours; azure contains some green, while ultramarine contains some violet. The clear daytime sky and the deep sea appear blue because of an optical effect known as Rayleigh scattering. An optical effect called Tyndall effect explains blue eyes. Distant objects appear more blue because of another optical effect called aerial perspective. Blue has been an important colour in art and decoration since ancient times. The semi-precious stone lapis lazuli was used in ancient Egypt for jewellery and ornament and later, in the Renaissance, to make the pigment ultramarine, the most expensive of all pigments. In ...

Masinga Reservoir
Masinga Hydroelectric Power Station, also Masinga Dam, is an embankment dam on the Tana River, the longest river in Kenya. It straddles the border of Embu and Machakos Counties in Eastern Province and is located about 106 km. (66 mi.), by road, northeast of Nairobi, Kenya's capital and largest city. Construction of the dam began in 1978. The dam was completed in 1981. It is owned by ''Tana and Athi Rivers Development Authority'' (TARDA). The dam is used for power production and is part of the Seven Forks Scheme. Dam Masinga Dam is a 60 m tall and 2,200 m long embankment dam. The volume of the dam is 4,950,000 m³. The dam contains a spillway and a bottom outlet. Reservoir At full reservoir level (maximum flood level of 1,056.5 m) the reservoir of the dam has a surface area of 120 km² and its total capacity is 1,56 million m³. Minimum operating level is normally 1,037 m. On June 26, KenGen shut down the power plant because the operating level had fallen to 1,03 ...

Water Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. 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 r ...

Thika Dam
The Thika dam is a 63 m high, 458 m crest length earthfill dam on the Thika River near Ndakaini, 50 km north of Nairobi, Kenya. The reservoir has a storage capacity of 70 million cubic meters and serves for drinking water supply. Water is treated at the Ngethu treatment works. The dam has increased the reliability of water supply to Nairobi, which suffered water shortages during the dry season before construction of the dam was completed in 1994. The dam has been financed by the African Development Bank, the World Bank, the European Investment Bank The European Investment Bank (EIB) is the European Union's investment bank and is owned by the EU Member States. It is one of the largest supranational lenders in the world. The EIB finances and invests both through equity and debt solution ... and the Kenyan government. Its construction had been delayed because of difficulties in land acquisition, leading to cost overruns. During construction the dam design h ...

Hydroelectric Power
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.

Overgrazing
Overgrazing occurs when plants are exposed to intensive grazing for extended periods of time, or without sufficient recovery periods. It can be caused by either livestock in poorly managed agricultural applications, game reserves, or nature reserves. It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity, and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds. Degrading land, emissions from animal agriculture and reducing the biomass in a ecosystem contribute directly to climate change. Overgrazing can be reversed or prevented by removing grazers in order to give plants time to recover between grazing events. Successful planned grazing strategies have been support in the American bison of the Great Plains, or migratory Wildebeests of the Africa ...

Indian Ocean
The Indian Ocean is the third-largest of the world's five oceanic divisions, covering or ~19.8% of the water on Earth's surface. It is bounded by Asia to the north, Africa to the west and Australia to the east. To the south it is bounded by the Southern Ocean or Antarctica, depending on the definition in use. Along its core, the Indian Ocean has some large marginal or regional seas such as the Arabian Sea, Laccadive Sea, Bay of Bengal, and Andaman Sea. Etymology The Indian Ocean has been known by its present name since at least 1515 when the Latin form ''Oceanus Orientalis Indicus'' ("Indian Eastern Ocean") is attested, named after India, which projects into it. It was earlier known as the ''Eastern Ocean'', a term that was still in use during the mid-18th century (see map), as opposed to the ''Western Ocean'' ( Atlantic) before the Pacific was surmised. Conversely, Chinese explorers in the Indian Ocean during the 15th century called it the Western Oceans. In Anci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aberdare Range
The Aberdare Range (formerly the Sattima Range, Kikuyu: ''Nyandarua'') is a 160 km (100 mile) long mountain range of upland, north of Kenya's capital Nairobi with an average elevation of . It straddles across the counties of Nyandarua, Nyeri, Muranga, Kiambu and Laikipia. The mountain range is located in west central Kenya, northeast of Naivasha and Gilgil and lies just south of the Equator. The mountain range is called Nyandarua among the Agikuyu people in whose territory this forest and mountain range is located. The name Nyandarua comes from the Kikuyu word rwandarua meaning a drying hide, due to the distinctive fold of its silhouette. Topology The Aberdare Range forms a section of the eastern rim of the Great Rift Valley running roughly north to south. On the west, the range falls off steeply into the Kinangop Plateau and then into the Great Rift Valley. On the east, the range slopes more gently. Lake Naivasha and the distant Mau Escarpment can be seen from peaks in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
