Trent Falls
Trent Falls is the confluence of the River Ouse and the River Trent which forms the Humber between Lincolnshire and the East Riding of Yorkshire in England. Location The River Ouse flows to the east where it turns into the Humber, and the River Trent flows northwards. It curves to the east near the confluence, although this is largely engineered, rather than natural. A training wall was built on the western bank of the Trent after the First World War, in an attempt to keep the channel in a known position. The rivers deposit large volumes of silt in this area, and charts for coastal shipping have to be updated monthly, but for smaller vessels, the channel can be considered to be reasonably static. Despite the training wall and a mini-lighthouse called ' Apex Light' which is situated at the end of the wall, navigation at Trent Falls is not simple. There are no real waterfalls, but there is a very rapid race of water at difficult stages of the tide (especially spring tides), and ...

Confluence
In geography, a confluence (also ''conflux'') occurs where two or more watercourses join to form a single channel (geography), channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the river source, source of a river of a new name (such as the confluence of the Monongahela River, Monongahela and Allegheny River, Allegheny rivers, forming the Ohio River); or where two separated channels of a river (forming a river island) rejoin downstream from their point of separation. Scientific study Confluences are studied in a variety of sciences. Hydrology studies the characteristic flow patterns of confluences and how they give rise to patterns of erosion, bars, and scour pools. The water flows and their consequences are often studied with mathematical models. Confluences are relevant to the distribution of living organisms (i.e., ecology) as well; "the general pattern [downstream o ...

Tidal Bore
A tidal bore, often simply given as bore in context, is a tidal phenomenon in which the leading edge of the incoming tide forms a wave (or waves) of water that travels up a river or narrow bay, reversing the direction of the river or bay's current. It is a strong tide that pushes up the river, against the current. Description Bores occur in relatively few locations worldwide, usually in areas with a large tidal range (typically more than between high and low tide) and where incoming tides are funneled into a shallow, narrowing river or lake via a broad bay. The funnel-like shape not only increases the tidal range, but it can also decrease the duration of the flood tide, down to a point where the flood appears as a sudden increase in the water level. A tidal bore takes place during the flood tide and never during the ebb tide. A tidal bore may take on various forms, ranging from a single breaking wavefront with a somewhat like a hydraulic jumpto undular bores, compr ...

Landforms Of The East Riding Of Yorkshire
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...

Turf Maze
Historically, a turf maze is a labyrinth made by cutting a convoluted path into a level area of short grass, sod, turf or lawn. Some had names such as Mizmaze, Troy Town, The Walls of Troy, Julian's Bower, or Shepherd's Race. This is the type of maze referred to by William Shakespeare in ''A Midsummer Night's Dream'' (Act 2, Scene 2) when Titania (Fairy Queen), Titania says: In some turf labyrinths, the groove cut in the turf is the path to be walked (sometimes marked with bricks or gravel); more commonly the turf itself forms the raised path which is marked out by shallow channels excavated between its twists and turns. Most British examples are based on one of two layouts: the Classical antiquity, Classical or the later, more complex Medieval type which is derived from it. Origins of the turf maze The earliest known use of the classical labyrinth pattern in the British Isles is on the Hollywood Stone, an incised granite boulder from County Wicklow, Ireland, dating from c.& ...

Julian's Bower
Julian's Bower or Julian Bower is a name given to turf mazes in several different parts of England. Only one of this name still exists, at Alkborough in North Lincolnshire. It has also been known by corrupted forms of the name, such as "Gillian's Bore" and "Gilling Bore". The 18th-century antiquary William Stukeley mentions a "Julian Bower" turf maze at Horncastle, Lincolnshire, and in nearby Louth there was a "Gelyan Bower", mentioned in accounts of 1554. At Goathland, North Yorkshire, there was a "July Park" or "St Julian's" maze. At Whinfell Forest there is a farm called Julian Bower, originally built to support the Keeper. It now lies outside the forest boundary. Some English turf mazes are very similar in their layout to Scandinavian labyrinths, which usually have their paths marked with stones. At Grothornet, near Vartdal in the Sunnmore district of Norway, there is a stone-lined labyrinth called "Den Julianske Borg" ("Julian's Castle"). The name is believed to be deriv ...

Western Marsh Harrier
The western marsh harrier (''Circus aeruginosus'') is a large harrier (bird), harrier, a bird of prey from temperate and subtropical western Palearctic, Eurasia and adjacent Africa. It is also known as the Eurasian marsh harrier. Formerly, a number of relatives were included in ''C. aeruginosus'', which was then known as "marsh harrier". The related taxa are now generally considered to be separate species: the eastern marsh harrier (''C. spilonotus''), the Papuan harrier (''C. spilothorax'') of eastern Asia and the Wallacea, the swamp harrier (''C. approximans'') of Australasia and the Madagascar marsh harrier (''C. maillardi'') of the western Indian Ocean islands. The western marsh harrier is often divided into two subspecies, the widely bird migration, migratory ''C. a. aeruginosus'' which is found across most of its range, and ''C. a. harterti'' which is resident all-year in north-west Africa. Taxonomy The western marsh harrier was Species description, formally described by th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eurasian Bittern
The Eurasian bittern or great bittern (''Botaurus stellaris'') is a wading bird in the bittern subfamily (Botaurinae) of the heron family Ardeidae. There are two subspecies, the northern race (''B. s. stellaris'') breeding in parts of Europe and across the Palearctic, as well as on the northern coast of Africa, while the southern race (''B. s. capensis'') is endemic to parts of southern Africa. It is a secretive bird, seldom seen in the open as it prefers to skulk in reed beds and thick vegetation near water bodies. Its presence is apparent in the spring, when the booming call of the male during the breeding season can be heard. It feeds on fish, small mammals, fledgling birds, amphibians, crustaceans and insects. The nest is usually built among reeds at the edge of bodies of water. The female incubates the clutch of eggs and feeds the young chicks, which leave the nest when about two weeks old. She continues to care for them until they are fully fledged some six weeks later.

Bearded Tit
The bearded reedling (''Panurus biarmicus'') is a small, long-tailed passerine bird found in reed beds near water in the temperate zone of Eurasia. It is frequently known as the bearded tit or the bearded parrotbill, as it historically was believed to be closely related to Tit (bird), tits or parrotbills. Today it is known to lack close relatives and it is the only species in the family Panuridae. Bearded reedlings are strongly sexually dimorphic and form life-long pairs. They are highly productive and can breed several times in a season. They mainly feed on small invertebrates in summer and plant seeds in winter. Taxonomy and systematics The bearded reedling was Species description, scientifically described in 1758 by the Swedish naturalist Carl Linnaeus in his 10th edition of Systema Naturae, 10th edition of ''Systema Naturae''. He placed it with the tit (bird), tits in the genus ''Parus'' and coined the binomial name ''Parus biarmicus''. Linnaeus based his entry on the "bear ...

Blacktoft Sands RSPB Reserve
Blacktoft Sands RSPB reserve is a nature reserve in the East Riding of Yorkshire, England. It is managed by the Royal Society for the Protection of Birds, which leases the site from Associated British Ports. Description The site is on the southern bank of the Ouse, west of its confluence with the River Trent, opposite the village of Blacktoft, and is a wetland. Being at the beginning of the Humber Estuary, the water is slightly saline. The reserve's tidal reedbed is the largest in England. It is managed using a mixture of grazing with our six konik horses, reed cutting and maintaining and excavation of pools within the reedbed. Wildlife As an RSPB reserve Blacktoft Sands is known for its birdlife. The headline species are wetland birds which are rare in Britain. Breeding birds include Western marsh harrier, great bittern and bearded reedling which are reedbed specialists, while the pied avocet prefers the saline lagoons. Hen harrier is a notable wintering species, joining th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Society For The Protection Of Birds
The Royal Society for the Protection of Birds (RSPB) is a Charitable_organization#United_Kingdom, charitable organisation registered in Charity Commission for England and Wales, England and Wales and in Office of the Scottish Charity Regulator, Scotland. It was founded in 1889. It works to promote bird conservation, conservation and protection of birds and the wider Natural environment, environment through public awareness campaigns, petitions and through the operation of Nature Reserve, nature reserves throughout the United Kingdom. In 2021/22 the RSPB had revenue of £157 million, 2,200 employees, 10,500 volunteers and 1.1 million members (including 195,000 youth members), making it one of the world's largest wildlife conservation organisations. The RSPB has many local groups and maintains 222 nature reserves. History The origins of the RSPB lie with two groups of women, both formed in 1889: * The Plumage League was founded by Emily Williamson at her house in Didsbury, Ma ...

Trent Aegir
The Trent Aegir, also known as the Eagre, is a tidal bore on the River Trent in England. At certain times of the year, the lower tidal reaches of the Trent experience a moderately large bore (up to five feet (1.5m) high). It is said to take its name from Ægir, a personification of the sea in Norse mythology, although this is disputed. A more likely derivation is from Old English ''ēagor'' (“flood, stream, water”). The Aegir occurs when a high spring tide meets the downstream flow of the river. The funnel shape of the river mouth exaggerates this effect, causing a large wave to travel upstream as far as Gainsborough, Lincolnshire, and sometimes beyond. The Aegir cannot travel much beyond Gainsborough as the shape of the river reduces the Aegir to little more than a ripple, and weirs north of Newark-on-Trent, Nottinghamshire stop its path completely. The Aegir can be seen at Gainsborough, Morton, East Stockwith, West Stockwith and Owston Ferry. The Environment Agency ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tide
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon (and to a much lesser extent, the Sun) and are also caused by the Earth and Moon orbiting one another. Tide tables can be used for any given locale to find the predicted times and amplitude (or " tidal range"). The predictions are influenced by many factors including the alignment of the Sun and Moon, the phase and amplitude of the tide (pattern of tides in the deep ocean), the amphidromic systems of the oceans, and the shape of the coastline and near-shore bathymetry (see '' Timing''). They are however only predictions, the actual time and height of the tide is affected by wind and atmospheric pressure. Many shorelines experience semi-diurnal tides—two nearly equal high and low tides each day. Other locations have a diurnal tide—one high and low tide each day. A "mixed tide"—two uneven magnitude tides a day—is a third regular category. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
