Balancing Lake
A balancing lake (also flood basin ) is a term used in the UK to describe a retention basin used to control flooding by temporarily storing flood waters. The term balancing pond is also used, though typically for smaller storage facilities for streams and brooks. In open countryside, heavy rainfall soaks into the ground and is released relatively slowly into watercourses (ditches, streams, rivers). In an urban area, the extent of hard surfaces (roofs, roads) means that the rainfall is dumped immediately into the drainage system. If left unchecked, this has the potential to cause flooding downstream. The function of a balancing lake as part of a '' sustainable urban drainage scheme'' is to contain this surge and release it slowly. Failure to do this, especially in older settlements without separate storm sewers and foul sewers, can cause serious pollution as well as flooding. Engineering At its simplest, a balancing lake can be constructed by creating a dam across a drain ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Priorslee Lake - Geograph
Priorslee is a large village in the Telford and Wrekin borough in Shropshire, England. It forms part of the St George's and Priorslee civil parish alongside Central Park (Telford), Central Park, Redhill, Snedshill and St George's, Shropshire, St George's. History The village occupies an area that was home to a Roman Empire, Roman settlement at nearby Red Hill. Roman coins were found in the surrounding area. Priors-Lee was formerly a chapelry in the parish of Shifnal, on 1 April 1898 Priors Lee became a separate civil parish, on 1 April 1934 the parish was abolished to form Oakengates. In 1931 the parish had a population of 2644. It later became part of Telford alongside neighbouring villages and towns between the 1960s and 1970s. St Peter's Church Until 1838, a chapel occupied the site of the present-day church. It was demolished and replaced by the church between 1825 and 1827. The church was then dedicated to Saint Peter and given Grade II listing. The church contains ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Ouzel
The River Ouzel , also known as the River Lovat, is a river in England, and a tributary of the River Great Ouse. It rises in the Chiltern Hills and flows north to join the Ouse at Newport Pagnell. It is usually called the ''River Ouzel'', except near Newport Pagnell where both names are used. The name ''Lovat'' was recorded (in the form 'Lovente') in the thirteenth century, a map of 1724 marks the river as "Lowsel R", and a map surveyed in 1765 shows it as 'Ouzel River'. The modern Ordnance Survey The Ordnance Survey (OS) is the national mapping agency for Great Britain. The agency's name indicates its original military purpose (see Artillery, ordnance and surveying), which was to map Scotland in the wake of the Jacobite rising of ... uses only the name ''Ouzel'', except north of Willen Lake where it is marked as 'River Ouzel or Lovat'.

Urban Runoff
Urban runoff is surface runoff of rainwater, landscape irrigation, and car washing created by urbanization. Impervious surfaces (roads, parking lots and sidewalks) are constructed during land development. During rain, storms, and other Precipitation (meteorology), precipitation events, these surfaces (built from materials such as Asphalt concrete, asphalt and concrete), along with rooftops, carry polluted stormwater to storm drains, instead of allowing the water to Infiltration (hydrology), percolate through soil. This causes lowering of the water table (because groundwater recharge is lessened) and flooding since the amount of water that remains on the surface is greater.Water Environment Federation Alexandria, VA; an American Society of Civil ...

Surface Runoff
Surface runoff (also known as overland flow or terrestrial runoff) is the unconfined flow of water over the ground surface, in contrast to ''channel runoff'' (or ''stream flow''). It occurs when excess rainwater, stormwater, meltwater, or other sources, can no longer sufficiently rapidly infiltrate in the soil. This can occur when the soil is #Saturation excess overland flow, saturated by water to its full capacity, and the rain arrives #Infiltration excess overland flow, more quickly than the soil can absorb it. Surface runoff often occurs because wikt:impervious#Adjective, impervious areas (such as roofs and Road surface, pavement) do not allow water to soak into the ground. Furthermore, runoff can occur either through natural or human-made processes. Surface runoff is a major component of the water cycle. It is the primary agent of Soil erosion#Rainfall and runoff, soil erosion by water. The land area producing runoff that drains to a common point is called a drainage basin. ...

Stormwater
Stormwater, also written storm water, is water that originates from precipitation (storm), including heavy rain and meltwater from hail and snow. Stormwater can soak into the soil ( infiltrate) and become groundwater, be stored on depressed land surface in ponds and puddles, evaporate back into the atmosphere, or contribute to surface runoff. Most runoff is conveyed directly as surface water to nearby streams, rivers or other large water bodies (wetlands, lakes and oceans) without treatment. In natural landscapes, such as forests, soil absorbs much of the stormwater. Plants also reduce stormwater by improving infiltration, intercepting precipitation as it falls, and by taking up water through their roots. In developed environments, such as cities, unmanaged stormwater can create two major issues: one related to the volume and timing of runoff ( flooding) and the other related to potential contaminants the water is carrying (water pollution). In addition to the pollutants carr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canada Geese
The Canada goose (''Branta canadensis''), sometimes called Canadian goose, is a large species of goose with a black head and neck, white cheeks, white under its chin, and a brown body. It is native to the arctic and temperate regions of North America, and it is occasionally found during migration across the Atlantic in northern Europe. It has been introduced to France, the United Kingdom, Ireland, Scandinavia, New Zealand, Japan, Chile, Argentina, and the Falkland Islands. Like most geese, the Canada goose is primarily herbivorous and normally migratory; often found on or close to fresh water, the Canada goose is also common in brackish marshes, estuaries, and lagoons. Extremely adept at living in human-altered areas, Canada geese have established breeding colonies in urban and cultivated habitats, which provide food and few natural predators. The success of this common park species has led to it often being considered a pest species because of its excrement, its depredation ...

Northern Lapwing
The northern lapwing (''Vanellus vanellus''), also known as the peewit or pewit, tuit or tewit, green plover, or (in Ireland and Great Britain) pyewipe or just lapwing, is a bird in the lapwing subfamily. It is common through temperate Palearctic, Eurosiberia. Taxonomy The northern lapwing was Species description, formally described by the Swedish naturalist Carl Linnaeus in 1758 in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the binomial nomenclature, binomial name ''Tringa vanellus''. The species is now placed with the other lapwings in the genus ''Vanellus'' that was introduced by the French zoologist Mathurin Jacques Brisson in 1760. The scientific name ''Vanellus'' is Medieval Latin for the northern lapwing and derives from ''vannus'', a Winnowing#In Greek culture, winnowing fan. The species is monotypic: no subspecies are recognised. The name ''lapwing'' has been variously attributed to the "lapping" sound its wings make in flight, f ...

Common Redshank
The common redshank or simply redshank (''Tringa totanus'') is a Eurasian wader in the large family Scolopacidae. Taxonomy The common redshank was formally described by the Swedish naturalist Carl Linnaeus in 1758 in the tenth edition of his ''Systema Naturae'' under the binomial name ''Scolopax totanus''. It is now placed with twelve other species in the genus ''Tringa'' that Linnaeus had introduced in 1758. The genus name ''Tringa'' is the Neo-Latin name given to the green sandpiper by the Italian naturalist Ulisse Aldrovandi in 1603 based on Ancient Greek ''trungas'', a thrush-sized, white-rumped, tail-bobbing wading bird mentioned by Aristotle. The specific ''totanus'' is from , the Italian name for this bird. Six subspecies are recognised: * ''T. t. robusta'' ( Schiøler, 1919) – breeds in Iceland and the Faroe Islands; non-breeding around the British Isles and west Europe * ''T. t. totanus'' (Linnaeus, 1758) – breeds in west, north Europe to west Siberia; winter ...

Little Ringed Plover
The little ringed plover (''Charadrius dubius'') is a small plover. The genus name ''Charadrius'' is a Late Latin word for a yellowish bird mentioned in the fourth-century Vulgate. It derives from Ancient Greek ''kharadrios'' a bird found in river valleys (''kharadra'', "ravine"). The specific ''dubius'' is Latin for doubtful, since Sonnerat, writing in 1776, thought this bird might be just a variant of common ringed plover. Description Adult little ringed plovers have a grey-brown back and wings, a white belly and a white breast with one black neckband. They have a brown cap, a white forehead, a black mask around the eyes with white above and a short dark bill. The legs are flesh-coloured and the toes are all webbed. This species differs from the larger ringed plover in leg colour, the head pattern, and the presence of a clear yellow eye-ring.

Ringed Plover
The common ringed plover or ringed plover (''Charadrius hiaticula'') is a species of bird in the family Charadriidae. It breeds across much of northern Eurasia, as well as Greenland. Taxonomy The common ringed plover was Species description, formally described in 1758 by the Swedish naturalist Carl Linnaeus in the 10th edition of Systema Naturae, tenth edition of his ''Systema Naturae'' under the current binomial nomenclature, binomial name ''Charadrius hiaticula''. Linnaeus specified the type locality (biology), type locality as "Europa & America" but this is now restricted to Sweden. The specific epithet ''hiaticula'' is late Medieval Latin for a plover. Three subspecies are recognised: * ''C. h. psammodromus'' Finn Salomonsen, Salomonsen, 1930 – Arctic of North Atlantic: Ellesmere Island and Baffin Island (northeast Canada, sporadic); Greenland, Iceland, Faroe Islands and Svalbard (north of Norway) * ''C. h. hiaticula'' Carl Linnaeus, Linnaeus, 1758 – temperate east Nort ...

Tufted Duck
The tufted duck (or tufted pochard) (''Aythya fuligula'') is a small diving duck with a population of nearly one million birds, found in northern Eurasia. They are partially migratory. The scientific name is derived from Ancient Greek , an unidentified seabird mentioned by authors such as Hesychius and Aristotle, and Latin 'soot' and ' 'throat'. It is a game bird. Taxonomy The tufted duck was formally described in 1758 by the Swedish naturalist Carl Linnaeus in the tenth edition of his ''Systema Naturae'' under the binomial name ''Anas fuligula''. He cited the Swiss naturalist Conrad Gessner who in 1555 had used the identical name ''Anas fuligula'' in his '' Historiae animalium''. Linnaeus specified the type locality as Europe but in 1761 restricted it to Sweden. The tufted duck is now one of 12 species placed in the genus '' Aythya'' that was introduced in 1822 by the German naturalist Friedrich Boie. The genus name is from Ancient Greek ''aithuia'', an unidentified se ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Tern
The common tern (''Sterna hirundo'') is a seabird in the family Laridae. This bird has a circumpolar distribution, its four subspecies breeding in Temperateness, temperate and subarctic regions of Europe, Asia and North America. It is strongly bird migration, migratory, wintering in coastal Tropics, tropical and Subtropics, subtropical regions. Breeding adults have light grey upperparts, white to very light grey underparts, a black cap, orange-red legs, and a narrow pointed bill. Depending on the subspecies, the bill may be mostly red with a black tip or all black. There are several similar species, including the partly Sympatry, sympatric Arctic tern, which can be separated on plumage details, leg and bill colour, or Bird vocalization, vocalisations. Breeding in a wider range of habitats than any of its relatives, the common tern nests on any flat, poorly vegetated surface close to water, including beaches and islands, and it readily adapts to artificial substrates such as ...
