Llanishen Reservoir
Llanishen Reservoir ( cy, Cronfa Ddŵr Llanisien) is a Victorian reservoir in North Cardiff in Wales. The reservoir is one of the reservoirs constructed as part of the Taff Fawr scheme for supplying water to Cardiff and was completed in 1886. It forms part of the Nant Fawr Corridor from the top of Roath Park to the countryside beyond Cyncoed. The reservoir was used for water supply until the mid-1970s when it became redundant. It was then used for leisure activities and for 'topping up' the adjacent Lisvane Reservoir until it was drained completely. After buying Hyder plc, its new owner Western Power Distribution (WPD), proposed to redevelop the reservoir site, but after a series of objections from national governing bodies, the County Council, local residents and both local and national politicians this was blocked. On 30 August 2013 WPD sold both Llanishen and Lisvane reservoirs to CELSA Group. In January 2016, Welsh Water acquired both Llanishen and Lisvane reservoirs from ...

Llanishen
Llanishen (Welsh Llanisien ''llan'' church + ''Isien'' Saint Isan) is a district and community in the north of Cardiff, Wales. Its population as of the 2011 census was 17,417. Llanishen is the home of the former HMRC tax offices, the tallest buildings in north Cardiff and a landmark for miles around. The office complex overlooks the Crystal and Fishguard estates, the Parc TÅ· Glas industrial estate, Llanishen village, leafy suburban roads and parks that constitute the district. Llanishen is also home to a leisure centre and the former Llanishen Reservoir, which is connected to a green corridor which bisects the city. History Originally wooded farm land, in A.D. 535 two monks came eastwards from the small religious settlement of Llandaff, aiming to establish new settlements, or "llans", in the land below Caerphilly Mountain. With fresh water from the Nant Fawr stream, one of the monks, Isan, founded his llan on the site of the modern day Oval Park. In 1089 at the Battle ...

John Frederick Bateman
John Frederick La Trobe Bateman (30 May 1810 – 10 June 1889) was an English civil engineer whose work formed the basis of the modern United Kingdom water supply industry. For more than 50 years from 1835 he designed and constructed reservoirs and waterworks. His largest project was the Longdendale Chain system that has supplied Manchester with much of its water since the 19th century. The construction of what was in its day the largest chain of reservoirs in the world began in 1848 and was completed in 1877. Bateman became "the greatest dam-builder of his generation". Bateman also worked on water supply systems for Glasgow, Belfast, Bolton, Chester, Dublin, Newcastle upon Tyne, Oldham, Perth, Stockport and Wolverhampton, amongst many others. He carried out projects abroad as well, including designing and constructing a drainage and water supply system for Buenos Aires, and water supply schemes for Naples, Constantinople and Colombo. He was President of the Institution o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Toad
The common toad, European toad, or in Anglophone parts of Europe, simply the toad (''Bufo bufo'', from Latin ''bufo'' "toad"), is a frog found throughout most of Europe (with the exception of Ireland, Iceland, and some Mediterranean islands), in the western part of North Asia, and in a small portion of Northwest Africa. It is one of a group of closely related animals that are descended from a common ancestral line of toads and which form a species complex. The toad is an inconspicuous animal as it usually lies hidden during the day. It becomes active at dusk and spends the night hunting for the invertebrates on which it feeds. It moves with a slow, ungainly walk or short jumps, and has greyish-brown skin covered with wart-like lumps. Although toads are usually solitary animals, in the breeding season, large numbers of toads converge on certain breeding ponds, where the males compete to mate with the females. Eggs are laid in gelatinous strings in the water and later hatch out into ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stonewort
Charales is an order of freshwater green algae in the division Charophyta, class Charophyceae, commonly known as stoneworts. Depending on the treatment of the genus ''Nitellopsis'', living (extant) species are placed into either one family ( Characeae) or two (Characeae and Feistiellaceae). Further families are used for fossil members of the order. Linnaeus established the genus ''Chara (alga), Chara'' in 1753. Taxonomy The higher level classification of green algae was unsettled . AlgaeBase places Charales within the class Charophyceae and its Circumscription (taxonomy), circumscription of the Phylum, division Charophyta. Families The number of families and their division into genera varies. , AlgaeBase accepts two families containing some extant species and four families containing only fossil species: * Characeae S.F.Gray * Feistiellaceae Schudack *†Aclistocharaceae X.G.Zhou (may be included in Characeae) *†Atopocharaceae R.E.Peck (may be included in Clavatoraceae) *â ...

Site Of Importance For Nature Conservation
Site of Nature Conservation Interest (SNCI), Site of Importance for Nature Conservation (SINC) and regionally important geological site (RIGS) are designations used by local authorities in the United Kingdom for sites of substantive local nature conservation and geological value. The Department for Environment, Food and Rural Affairs has recommended the generic term 'local site', which is divided into 'local wildlife site' and 'local geological site'. There are approximately 35,000 local sites, and according to the former Minister for Biodiversity, Jim Knight, they make a vital contribution to delivering the United Kingdom Biodiversity Action Plan, UK and Local Biodiversity Action Plans and the Geodiversity Action Plan, as well as maintaining local natural character and distinctiveness. Sites of Special Scientific Interest (SSSIs) and local nature reserves (LNRs) have statutory protection, but they are only intended to cover a representative selection of sites, and Local sites are ...

Distribution Network Operator
A distribution network operator (DNO), also known as a distribution system operator (DSO), is the operator of the electric power distribution system which delivers electricity to most end users. Each country may have many local distribution network operators, which are separate from the transmission system operator, responsible for transporting power in bulk around the country. France In France, Enedis, a subsidiary of EDF, distributes approximately 95% of electricity, with the remaining 5% distributed by 160 local electricity and gas distribution companies (''entreprises locales de distribution d'électricité et de gaz'' or ELD). Jean ProriolRapport d'information déposé par la commission des affaires économiques de l'Assemblée nationale assemblee-nationale.fr du 5 avril 2011, consulté le 30 avril 2020 Great Britain In Great Britain, distribution network operators are licensed by the Office of Gas and Electricity Markets.

PPL (utility)
PPL Corporation is an energy company headquartered in Allentown, Pennsylvania in the Lehigh Valley region of eastern Pennsylvania. The company is publicly traded on the New York Stock Exchange. History Pennsylvania Power & Light was founded in 1920 out of a merger of eight smaller Pennsylvania utilities. It gradually extended its service territory to a crescent-shaped region of central and northeastern Pennsylvania stretching from Lancaster through the Lehigh Valley into Scranton and Wilkes-Barre. In 1995, it reorganized as a holding company, PP&L Resources, which changed its name to its current name, PPL Corporation, in 2000. The company limited its activities to Pennsylvania until deregulation of electrical utilities in the 1990s encouraged PPL to purchase assets in other states. The largest of these transactions was PPL's 1998 purchase of 13 plants from Montana Power (leaving NorthWestern Energy – the buyer of the former Montana Power transmission and distribution systems ...

SWALEC
SWALEC was an electricity supply and distribution company in South Wales, established in 1989 following the de-regulation of the electricity supply industry in the United Kingdom. The business has seen several changes of ownership from 1996, and the SWALEC brand has been used for retail gas supply as well as electricity. Today Western Power Distribution runs the distribution network business, and SWALEC Contracting is a trading name of OVO Energy. Predecessor The South Wales Electricity Board (SWEB) was formed in 1948 under the Electricity Act 1947, which brought about the nationalisation and merger of local authority and private electricity companies. The SWEB was responsible for the purchase of electricity from the electricity generator (the Central Electricity Generating Board from 1958) and the distribution and sale of electricity to customers. The key members of the Board were: Chairman W.D.D. Fenton (1964, 1967), Deputy Chairman H. Pryce-Jones (1964, 1967), full-time memb ...

Anticline
In structural geology, an anticline is a type of fold that is an arch-like shape and has its oldest beds at its core, whereas a syncline is the inverse of an anticline. A typical anticline is convex up in which the hinge or crest is the location where the curvature is greatest, and the limbs are the sides of the fold that dip away from the hinge. Anticlines can be recognized and differentiated from antiforms by a sequence of rock layers that become progressively older toward the center of the fold. Therefore, if age relationships between various rock strata are unknown, the term antiform should be used. The progressing age of the rock strata towards the core and uplifted center, are the trademark indications for evidence of anticlines on a geologic map. These formations occur because anticlinal ridges typically develop above thrust faults during crustal deformations. The uplifted core of the fold causes compression of strata that preferentially erodes to a deeper st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...

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 diagnostic of till. image:Glacial till exposed in roadcut-750px.jpg, Glacial till with tufts of grass Till or glacial till is unsorted glacier, glacial sediment. 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] |
