River Witham
The River Witham is a river almost entirely in the county of Lincolnshire in the east of England. It rises south of Grantham close to South Witham at , passes through the centre of Grantham (where it may be closely followed using the Riverside Walk through Wyndham Park and Queen Elizabeth Park), passes Lincoln at and at Boston, , flows into The Haven, a tidal arm of The Wash, near RSPB Frampton Marsh. The name "Witham" seems to be extremely old and of unknown origin.; see Old European hydronymy Archaeological and documentary evidence shows the importance of the Witham as a navigable river from the Iron Age onwards. From Roman times it was navigable to Lincoln, from where the Fossdyke was constructed to link it to the River Trent. The mouth of the river moved in 1014 following severe flooding, and Boston became important as a port. From 1142 onwards, sluices were constructed to prevent flooding by the sea, and this culminated in the Great Sluice, which was constructed in 1 ...

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

The Wash
The Wash is a rectangular bay and multiple estuary at the north-west corner of East Anglia on the East coast of England, where Norfolk, England, Norfolk meets Lincolnshire and both border the North Sea. One of Britain's broadest estuaries, it is fed by the rivers River Witham, Witham, River Welland, Welland, River Nene, Nene and Great Ouse. It is a biological Site of Special Scientific Interest. It is also a Nature Conservation Review site, Grade I, a National nature reserve (United Kingdom), National Nature Reserve, a Ramsar site, a Special Area of Conservation and a Special Protection Area. It is in the Norfolk Coast AONB, Norfolk Coast Area of Outstanding Natural Beauty and part of it is the Snettisham Royal Society for the Protection of Birds nature reserve. Geography The Wash makes a large indentation in the coastline of Eastern England that separates the curved coast of East Anglia from Lincolnshire. It is a large bay with three roughly straight sides meeting at right an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ordnance Datum
In the British Isles, an ordnance datum or OD is a vertical datum used by an ordnance survey as the basis for deriving altitudes on maps. A spot height may be expressed as AOD for "above ordnance datum". Usually mean sea level (MSL) is used for the datum. In particular: * In Great Britain, OD for the Ordnance Survey is ODN (Ordnance Datum Newlyn), defined as the MSL as recorded by the tidal gauge at Newlyn in Cornwall between 1915 and 1921. **Prior to 1921, OD was defined as MSL as recorded in the Victoria Dock, Liverpool, during a short period in 1844 (ODL). * In Northern Ireland, OD for the Ordnance Survey of Northern Ireland is Belfast Ordnance Datum, the MSL at Clarendon Dock, Belfast, between 1951 and 1956. * In the Republic of Ireland, OD for the Ordnance Survey of Ireland is Malin Ordnance Datum: the MSL at Portmoor Pier, Malin Head, County Donegal, between 1960 and 1969.

Isostatic Rebound
Post-glacial rebound (also called isostatic rebound or crustal rebound) is the rise of land masses after the removal of the huge weight of ice sheets during the last glacial period, which had caused isostatic depression. Post-glacial rebound and isostatic depression are phases of glacial isostasy (glacial isostatic adjustment, glacioisostasy), the deformation of the Earth's crust in response to changes in ice mass distribution. The direct raising effects of post-glacial rebound are readily apparent in parts of Northern Eurasia, Northern America, Patagonia, and Antarctica. However, through the processes of ''ocean siphoning'' and ''continental levering'', the effects of post-glacial rebound on sea level are felt globally far from the locations of current and former ice sheets.Milne, G.A., and J.X. Mitrovica (2008) ''Searching for eustasy in deglacial sea-level histories.'' Quaternary Science Reviews. 27:2292–2302. Overview During the last glacial period, much of northern Eu ...

Peterborough
Peterborough () is a cathedral city in Cambridgeshire, east of England. It is the largest part of the City of Peterborough unitary authority district (which covers a larger area than Peterborough itself). It was part of Northamptonshire until 1974, when county boundary change meant the city became part of Cambridgeshire instead. The city is north of London, on the River Nene which flows into the North Sea to the north-east. In 2020 the built-up area subdivision had an estimated population of 179,349. In 2021 the Unitary Authority area had a population of 215,671. The local topography is flat, and in some places, the land lies below sea level, for example in parts of the Fens to the east and to the south of Peterborough. Human settlement in the area began before the Bronze Age, as can be seen at the Flag Fen archaeological site to the east of the current city centre, also with evidence of Roman occupation. The Anglo-Saxon period saw the establishment of a monastery, Medeshams ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Nene
The River Nene ( or : see below) is a river in the east of England that rises from three sources in Northamptonshire.OS Explorer Map sheet 223, Northampton & Market Harborough, Brixworth & Pitsford Water. The river is about long, about of which forms the border between Cambridgeshire and Norfolk. It is the tenth-longest river in the United Kingdom, and is navigable for , from Northampton to The Wash. Etymology and pronunciation Spelling of the river's name has altered over time; it was called the "Nenn" or "Nyn" in an 1810 engraving by draughtsmen George Cole and John Roper, while the Ordnance Survey of 1885 used what has since become standard spelling, "Nene". The origin and meaning of the River Nene's name is unknown. The earliest known examples, which date back to the 10th century AD, have been linked to Indo-European root words for snow, rain, or washing, but a direct connection is purely speculative.

Fens Waterways Link
The Fens Waterways Link is a project to improve recreational boating opportunities in the counties of Cambridgeshire and Lincolnshire, England. By a combination of improvements to existing waterways and the construction of new links a circular route between Lincoln, Peterborough, Ely and Boston is planned. The project is being organised by the Environment Agency and financed from the Regional Development Agency and the European Union. A separate, complementary waterway is the Bedford and Milton Keynes Waterway, opening up a route for broader beam boats between The Fens and the rest of Britain's canal network. History The idea of creating a navigable waterway between Boston and Peterborough was promoted in 2005. It was described by the Environment Agency as the biggest project for the enhancement of waterways in Europe at the time, and would make of waterways accessible to inland boats, without them having to venture into the Wash. Lincolnshire has a greater length of rivers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
South Forty-Foot Drain
The South Forty-Foot Drain, also known as the Black Sluice Navigation, is the main channel for the land-drainage of the Black Sluice Level in the Lincolnshire Fens. It lies in eastern England between Guthram Gowt and the Black Sluice pumping station on The Haven, at Boston. The Drain has its origins in the 1630s, when the first scheme to make the Fen land available for agriculture was carried out by the Earl of Lindsey, and has been steadily improved since then. Water drained from the land entered The Haven by gravity at certain states of the tide until 1946, when the Black Sluice pumping station was commissioned. The Drain was navigable until 1971, when improvements to the pumping station led to the entrance lock being removed. It is currently being upgraded to navigable status by the Environment Agency, as part of the Fens Waterways Link, with a new entrance lock being completed in December 2008, giving access to the first of the drain, and the upgrading of the southern se ...

Witham Navigable Drains
The Witham Navigable Drains are located in Lincolnshire, England, and are part of a much larger drainage system managed by the Witham Fourth District Internal Drainage Board. The Witham Fourth District comprises the East Fen and West Fen, to the north of Boston, which together cover an area of . In total there are over of drainage ditches, of which under are navigable. Navigation is normally only possible in the summer months, as the drains are maintained at a lower level in winter, and are subject to sudden changes in level as a result of their primary drainage function, which can leave boats stranded. Access to the drains is from the River Witham at Anton's Gowt Lock. The area is bounded by the River Witham to the south and west, and the Steeping River to the north. Since the 11th century, there have been attempts to prevent the fens from flooding, so that they could be used for agriculture. A major advance was made in the seventeenth century, when Adventurers built drains in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bardney
Bardney is a village and civil parish in the West Lindsey district of Lincolnshire, England. The population of the civil parish was 1,643 at the 2001 census increasing to 1,848 (including Southrey) at the 2011 census. The village sits on the east bank of the River Witham and east of the city and county town of Lincoln. __TOC__ History Two Roman artefacts have been found in Bardney; a gemstone and a coin. Nearby villages show evidence of Roman settlement, particularly Potterhanworth Booths and Branston Booths. The place-name is Old English in origin, and means "island of a man called Bearda". It occurs in the ''Anglo-Saxon Chronicle'', under the year 716, as "Bearddanig", and in ''Domesday Book'' as "Bardenai". Once the site of a mediaeval abbey, ruined in Henry VIII's dissolution of the monasteries, agricultural improvement made the village prosperous in the 19th century. Improved transport, first on the River and then the arrival of several railways caused considerable e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
