Reservoirs
A reservoir (; ) is an enlarged lake behind a dam, usually built to store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. 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 reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by creeks, rivers or rainwater that runs off the surrounding forested catchments, or '' off-stream reservoirs'', which receive diverted water from a nearby stream or aqueduct or pipeline water from other on-stream reservoirs. Dams are typicall ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Nasser
Lake Nasser ( ', ) is a large reservoir (water), reservoir in southern Egypt and northern Sudan. It was created by the construction of the Aswan Dam, Aswan High Dam and is one of the List of reservoirs by volume, largest man-made lakes in the world. Before its creation, the project faced opposition from Sudan as it would encroach on land in the northern part of the country, where many Nubian people lived who would have to be resettled. In the end Sudan's land near the area of Lake Nasser was mostly flooded by the lake. The lake has become an important economic resource in Egypt, improving agriculture and touting robust fishing and tourism industries. Strictly speaking, "Lake Nasser" refers only to the much larger portion of the lake that is in Egyptian territory (83% of the total), with the Sudanese preferring to call their smaller body of water Lake Nubia ( ', ). __TOC__ Physical characteristics The lake is some long and across at its widest point, which is near the Tropic ...

Water Storage
Water storage is a broad term referring to storage of both potable water for consumption, and non potable water for use in agriculture. In both developing countries and some developed countries found in tropical climates, there is a need to store potable drinking water during the dry season. In agriculture water storage, water is stored for later use in natural water sources, such as groundwater aquifers, soil water, natural wetlands, and small artificial ponds, tanks and reservoirs behind major dams. Storing water invites a host of potential issues regardless of that water's intended purpose, including contamination through organic and inorganic means. Types Groundwater Groundwater is located beneath the ground surface in soil pore spaces and in the fractures of rock formations. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely satur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Water Diversion
Interbasin transfer or transbasin diversion are (often hyphenated) terms used to describe man-made conveyance schemes which move water from one river basin where it is available, to another basin where water is less available or could be utilized better for human development. The purpose of such water resource engineering schemes can be to alleviate water shortages in the receiving basin, to generate electricity, or both. Rarely, as in the case of the Glory River which diverted water from the Tigris to Euphrates River in modern Iraq, interbasin transfers have been undertaken for political purposes. While ancient water supply examples exist, the first modern developments were undertaken in the 19th century in Australia, India and the United States, feeding large cities such as Denver and Los Angeles. Since the 20th century many more similar projects have followed in other countries, including Israel and China, and contributions to the Green Revolution in India and hydropower develop ...

Llyn Celyn
Llyn Celyn () is a reservoir constructed between 1960 and 1965 including the highly controversial Tryweryn flooding in the valley of the River Afon Tryweryn, Tryweryn in Gwynedd, Wales. This included the forcible removal of the Capel Celyn village residents despite protest and opposition of Welsh MPs. With an area of , it measures roughly long by wide, and has a maximum depth of . It has the capacity to hold of water. It was originally to be named ''Llyn Tryweryn Mawr'' (meaning "great Tryweryn lake"), but in September 1964 Liverpool Corporation agreed to the name change following a letter from the Tryweryn Defence Committee. Construction and opposition Construction of the reservoir for Liverpool Corporation Waterworks involved flooding the village of Capel Celyn and adjacent farmland, a deeply controversial move. Much of the opposition was brought about because the village was a stronghold of Culture of Wales, Welsh culture and the Welsh language, whilst the reservoir w ...

East Branch Reservoir
East Branch Reservoir, is a reservoir in the town of Southeast, New York, near the village of Brewster. Part of the New York City water supply system, it was formed by impounding the East Branch of the Croton River. Forming part of the Croton Watershed, it was placed into service in 1891, and lies some north of the city, in the southeast corner of Putnam County. History The East Branch Reservoir has a surface area of , reaches a mean depth of , and holds at full capacity. It drains a area that includes Bog Brook Reservoir. Its water flows back into the East Branch of the Croton River south of the dam, then into The Diverting Reservoir, then via the Croton River to the Muscoot and the New Croton reservoirs, into the New Croton Aqueduct. Water from the aqueduct flows into the Jerome Park Reservoir in the Bronx for daily distribution. One of two double reservoirs in NYC's system, it is connected to the Bog Brook impoundment via a tunnel. When the two were being built, t ...

Hydroelectric Power Generation
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, 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.

Off-stream Reservoir
An off-stream reservoir is a reservoir that is not located on a streambed, and is supplied by a pipeline, aqueduct or an adjacent stream. San Luis Reservoir is the largest off-stream reservoir in the United States. Although it is located on a small stream, it gets the vast majority of its water from the California Aqueduct The Governor Edmund G. Brown California Aqueduct is a system of canals, tunnels, and pipelines that conveys water collected from the Sierra Nevada and valleys of Northern and Central California to Southern California. Named after California Gov ... by pumping aqueduct water up-hill to the reservoir. References Category;California Reservoirs {{geo-term-stub ...

Artificial Lake
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of oceans or larg ...
