Kainji Dam
Kainji Dam is a dam across the Niger River in Niger State of Central Nigeria. Construction of the dam was carried out by Impregilo (a consortium of Italian Civil Engineering Contractors) to designs by Joint Consultants, Balfour Beatty and Nedeco, and began in 1964 to be completed in 1968. The total cost was estimated at US$209 million (equivalent to about US$ billion in dollars), with one-quarter of this amount used to resettle people displaced by the construction of the dam and its reservoir, Kainji Lake. Dimensions Kainji Dam extends for about , including its saddle dam, which closes off a tributary valley. The primary section across the outflow to the Niger is . Most of the structure is made from earth, but the centre section, housing the hydroelectric turbines, was built from concrete. This section is high. Kanji Dam is one of the longest dams in the world. Power station The dam was designed to have a generating capacity of ; however, only 8 of its 12 turbines have been ins ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kainji Lake
Kainji Lake, in North Central Nigeria, is a reservoir on the Niger River, formed by the Kainji Dam. It was formed in 1968 and is a part of Niger State and Kebbi State. Kainji Lake National Park (KNLP), situated around the lake, is Nigeria's oldest National Park, established in 1976. Kanji Dam The Kainji Dam is situated in Northern Niger State and generates power for most towns in Nigeria. It was built from 1964 to 1968 and cost about 209 million dollars, a quarter of which was used to relocate the original population. Together with a smaller dam for a minor stream, it is long and high in the middle. It has a capacity of 12 turbines producing a total of 960 MW, but only 8 were installed, producing 760 MW. Part of the production is sold to the neighbouring country of Niger. National Park Kainji Lake National Park (KNLP) (headquarters Wawa) is situated north of Lagos, close to the border with the Republic of Benin. It comprises two sectors, Borgu Game Reserve and Zugurma Game ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tributary Valley
Side valleys and tributary valleys are valleys whose brooks or rivers flow into greater ones. Upstream, the valleys can be classified in an increasing order which is equivalent to the usual orographic order: the tributaries are ordered from those nearest to the source of the river to those nearest to the mouth of the river. A confluence is where two or more tributaries or rivers flow together. Orographic order (e.g. Humber) In the orographic classification (order of rivers) the tributary river has order ''n+1'', if ''n'' describes the primary (or main) river. A river which flows directly into the ocean (e.g. the English rivers Thames or Humber) has the orographic order n=1, the River Ouse n=2, the Wharfe n=3 and so on. Geomorphology The term "side valley" is used for ''higher order valleys'' near mountains (example above: the Pennines), as opposed to lower valleys that do not have a strong relief. This is because the " main stem river" (into which the secondary river flows) ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams In Nigeria
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] |

Fishing Industry
The fishing industry includes any industry or activity concerned with taking, culturing, processing, preserving, storing, transporting, marketing or selling fish or fish products. It is defined by the Food and Agriculture Organization as including recreational, subsistence and commercial fishing, and the related harvesting, processing, and marketing sectors.FAO Fisheries Section: Glossary''Fishing industry.''Retrieved 28 May 2008. The commercial activity is aimed at the delivery of fish and other seafood products for human consumption or as input factors in other industrial processes. The livelihood of over 500 million people in developing countries depends directly or indirectly on fisheries and aquaculture. The fishing industry is struggling with environmental and welfare issues, including overfishing and occupational safety. Additionally, the combined pressures of climate change, biodiversity loss and overfishing endanger the livelihoods and food security of a substantial porti ...

Turbine
A turbine ( or ) (from the Greek , ''tyrbē'', or Latin ''turbo'', meaning vortex) is a rotary mechanical device that extracts energy from a fluid flow and converts it into useful work. The work produced by a turbine can be used for generating electrical power when combined with a generator.Munson, Bruce Roy, T. H. Okiishi, and Wade W. Huebsch. "Turbomachines." Fundamentals of Fluid Mechanics. 6th ed. Hoboken, NJ: J. Wiley & Sons, 2009. Print. A turbine is a turbomachine with at least one moving part called a rotor assembly, which is a shaft or drum with blades attached. Moving fluid acts on the blades so that they move and impart rotational energy to the rotor. Early turbine examples are windmills and waterwheels. Gas, steam, and water turbines have a casing around the blades that contains and controls the working fluid. Credit for invention of the steam turbine is given both to Anglo-Irish engineer Sir Charles Parsons (1854–1931) for invention of the reaction turbine, and to ...

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.
