Llyn Clywedog
The Clywedog Reservoir ( cy, Llyn Clywedog) is a reservoir near Llanidloes, Wales on the head-waters of the River Severn. The construction of the reservoir was enabled by an Act of Parliament which asserted that ''"At certain times the flow of water in the river is inadequate ... unless that flow were regulated so as to ensure that at those times water in addition to the natural flow will flow down the river."'' Purpose Its primary purpose was to regulate the flow in the River Severn to mitigate flooding and provide support for drinking water abstractions for the West Midlands. It was completed in 1967 and is situated near the B4518 road north of Llanidloes, Powys. It regulates the flow of water in the River Severn by releasing water into the river channel during low flow periods and re-filling during the wetter winter months. This enables major water abstractions to be made from the River Severn to supply the West Midlands with of drinking water. Capacity is held in the rese ...

Elenydd
Elenydd () is an upland area of Mid Wales, extending across parts of northern and eastern Ceredigion and Powys between Aberystwyth and Rhayader. Elenydd is also a name given to the medieval commote of Cwmwd Deuddwr which covered approximately the same area. The area is an upland plateau of moorland and rough grazing within the Cambrian Mountains, source of the rivers Elan, Severn, Teifi, Towy and Wye. Elenydd is generally interpreted to mean the upland area between Pumlumon in the north and Mynydd Epynt in the south. The term " Desert of Wales" is sometimes applied to this or a wider area. Much of Elenydd is open land with public access, following the Countryside and Rights of Way Act 2000, widely known as the "CROW Act". Specific areas within Elenydd are designated as being of nature conservation importance. Etymology The name means the "area adjoining the Elan", which river name probably arises from Welsh ''elain'', meaning fawn or hind; -''ydd'' is a suffix denot ...

Buttress Dams
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient buildings, as a means of providing support to act against the lateral (sideways) forces arising out of inadequately braced roof structures. The term ''counterfort'' can be synonymous with buttress and is often used when referring to dams, retaining walls and other structures holding back earth. Early examples of buttresses are found on the Eanna Temple (ancient Uruk), dating to as early as the 4th millennium BC. Terminology In addition to flying and ordinary buttresses, brick and masonry buttresses that support wall corners can be classified according to their ground plan. A clasping or clamped buttress has an L shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses are set back from the c ...

Dams In Powys
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] |

Reservoirs In Powys
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 re ...

Osprey
The osprey (''Pandion haliaetus''), , also called sea hawk, river hawk, and fish hawk, is a diurnal, fish-eating bird of prey with a cosmopolitan range. It is a large raptor reaching more than in length and across the wings. It is brown on the upperparts and predominantly greyish on the head and underparts. The osprey tolerates a wide variety of habitats, nesting in any location near a body of water providing an adequate food supply. It is found on all continents except Antarctica, although in South America it occurs only as a non-breeding migrant. As its other common names suggest, the osprey's diet consists almost exclusively of fish. It possesses specialised physical characteristics and exhibits unique behaviour to assist in hunting and catching prey. As a result of these unique characteristics, it has been given its own taxonomic genus, ''Pandion'', and family, Pandionidae. Taxonomy The osprey was described by Carl Linnaeus under the name ''Falco haliaeetus'' in his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hydro-electric
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.
