Ystradfellte Reservoir
Ystradfellte Reservoir is a water storage reservoir on the Afon Dringarth in the upland area of Fforest Fawr within the Brecon Beacons National Park in South Wales. It lies just north of the village of Ystradfellte in the county of Powys at OS Grid ref SN 946178. The embankment is long by high. When full the water surface is above sea level. Construction The reservoir was constructed between 1907 and 1914 by Neath Rural District Council for the supply of water. A temporary railway track was constructed for from the village of Penderyn to transport building materials to the dam site. Limestone was obtained from Penderyn Quarry and puddle clay was excavated from the glacial till image:Geschiebemergel.JPG, Closeup of glacial till. Note that the larger grains (pebbles and gravel) in the till are completely surrounded by the matrix of finer material (silt and sand), and this characteristic, known as ''matrix support'', is d ... at nearby Cilhepste Coed.

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.

Rural District
Rural districts were a type of local government area – now superseded – established at the end of the 19th century in England, Wales, and Ireland for the administration of predominantly rural areas at a level lower than that of the Administrative county, administrative counties.__TOC__ England and Wales In England and Wales they were created in 1894 (by the Local Government Act 1894) along with Urban district (Great Britain and Ireland), urban districts. They replaced the earlier system of sanitary districts (themselves based on poor law unions, but not replacing them). Rural districts had elected rural district councils (RDCs), which inherited the functions of the earlier sanitary districts, but also had wider authority over matters such as local planning, council house, council housing, and playgrounds and cemeteries. Matters such as education and major roads were the responsibility of county councils. Until 1930 the rural district councillors were also poor law gu ...

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.

Afon Hepste
The Afon Hepste is a river in Powys, Wales, though partly forming the county's border with Rhondda Cynon Taf. It runs wholly within the Brecon Beacons National Park. Its headwaters, the Afon y Waun, Nant y Cwrier and Nant Hepste Fechan, rise on the Old Red Sandstone dip-slopes of Fforest Fawr and combine to form the Afon Hepste near the farmstead of Hepste Fechan. It enters onto the Carboniferous Limestone outcrop near this point and sections of its course downstream remain dry in all but flood conditions as the flow disappears underground. The river flows over the Millstone Grit outcrop from some way beyond Hepste Bridge.British Geological Survey 1:50,000 map no 231 'Merthyr Tydfil' & accompanying memoir The Hepste plunges over a band of resistant gritstone to form Sgwd yr Eira (translated from Welsh as 'fall of snow'). A public footpath runs behind this fall, making it one of the most popular destinations in an area that has become known as Waterfall Country. One mile dow ...

Glacial Till

Till is derived from the erosion and entrainment of material by the moving ice of a glacier. It is deposited some distance down-ice to form terminal, lateral, medial and ground moraines. Till is classified into primary deposits, laid down directly by glaciers, and secondary deposits, reworked by fluvial transport and other processes. Description Till is a form of '' glacial drift'', which is rock material transported by a glacier and deposited directly from the ice or from running water emerging from the ice. It is distinguished from other forms of drift in that it is depos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Puddling (engineering)
Puddling is both the material and the process of lining a water body such as a channel or pond with puddle clay (puddle, puddling) – a watertight (low hydraulic conductivity) material based on clay and water mixed to be workable. Puddle clay as a lining Puddling is used in maintaining canals or reservoirs on permeable ground. The technique of puddling and its use was developed by early canal engineer James Brindley; it is considered his greatest contribution to engineering. This processed material was used extensively in UK canal construction in the period starting circa 1780. Starting about 1840 puddle clay was used more widely as the water-retaining element (or core) within earthfill dams, particularly in the Pennines. Its usage in UK dams was superseded about 1960 by the use of rolled clay in the core, and better control of moisture content. A considerable number of early notable dams were built in that era and they are now sometimes referred to as the 'Pennines embankment' ...

Afon Mellte
Afon Mellte or the River Mellte is a river in south Wales. It is formed by the confluence of the Afon Llia and the Afon Dringarth. It then flows south through the village of Ystradfellte to Pontneddfechan where it joins with the Nedd Fechan to become the River Neath ( cy, 'Afon Nedd'). The river derives its name from 'mellt' - the Welsh word for 'lightning' - after its tendency to rise and fall rapidly in response to heavy rainfall. Underground section The entire river runs underground for 1/2 km at Porth yr Ogof as it crosses the Carboniferous Limestone outcrop. It resurges at Pwll Glas. There are fifteen known entrances to the cave system. It is a complex maze of passageways, large and small, mostly developed along one or two major bedding planes. In extreme flood conditions the entire cave can flood to the roof. It is used heavily by school and adventure groups though sections of the cave can be hazardous for the unwary. There have been a number of fatalities ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
