Middlesex Filter Beds Weir
The Middlesex Filter Beds Weir, or Lea Bridge Road Weir, marks the start of the Hackney Cut, an artificial channel of the River Lee Navigation built in 1770, in the London Borough of Hackney. The weir lies between the former Middlesex Filter Beds – now a nature reserve – and the Thames Water treatment works at Lea Bridge Road. Excess water from the Navigation passes over the weir into the former natural channel of the River Lee that passes in a large loop to the east of the modern water course, as the Old River Lea. The natural water course travels and rejoins the Navigation below Old Ford Lock Old Ford Lock is a paired lock and weir on the River Lee Navigation, in the London Borough of Tower Hamlets, England. It is at Fish Island in Old Ford and takes its name from the natural ford which used to cross the River Lea. Tidal section ....

Middlesex Filter Beds Weir-Head
Middlesex (; abbreviation: Middx) is a historic county in southeast England. Its area is almost entirely within the wider urbanised area of London and mostly within the ceremonial county of Greater London, with small sections in neighbouring ceremonial counties. Three rivers provide most of the county's boundaries; the Thames in the south, the Lea to the east and the Colne to the west. A line of hills forms the northern boundary with Hertfordshire. Middlesex county's name derives from its origin as the Middle Saxon Province of the Anglo-Saxon Kingdom of Essex, with the county of Middlesex subsequently formed from part of that territory in either the ninth or tenth century, and remaining an administrative unit until 1965. The county is the second smallest, after Rutland, of the historic counties of England. The City of London became a county corporate in the 12th century; this gave it self-governance, and it was also able to exert political control over the rest of Middles ...

Hackney Cut
The Hackney Cut is an artificial channel of the Lee Navigation built in England in 1769 by the River Lea Trustees to straighten and improve the Navigation. It begins at the Middlesex Filter Beds Weir, below Lea Bridge, and is situated in the (modern) London Borough of Hackney. When built it contained two pound locks and a half-lock, but was rebuilt to handle larger barges in the 1850s, and now only Old Ford Lock, which is actually a duplicated pair, remains. History The River Lea (or Lee) has a long history of use for navigation, with records indicating that the Abbot of Waltham was authorised to make improvements in 1190, and evidence for tidal gates at Bow from the reign of King Edward I, when Henry de Bedyk, the prior at Halliwell Priory and owner of the nearby tide mills, erected a structure some time before 1307. River levels were managed by flash locks or sluices, and as the volumes of traffic using the river increased, there was friction between the bargees and the mil ...

River Lee Navigation
The Lee Navigation is a canalised river incorporating the River Lea (also called the River Lee along the sections that are navigable). It flows from Hertford Castle Weir to the River Thames at Bow Creek (England), Bow Creek; its first lock is Hertford Lock and its last Bow Locks. Name The Lee Navigation is named by Acts of Parliament and is so marked on Ordnance Survey maps. Constructed elements and human features are spelled Lee, such as the canal system and Lee Valley Park. The un-canalized river is spelled Lea, along with other natural features such as Lower Lea Valley. History The River Lea is a major tributary of the River Thames. It has a long association with navigation, as the marshes of Walthamstow have produced a dugout canoe from the Bronze Age and parts of a Saxon barge. According to the ''Anglo-Saxon Chronicle'', the river was used by Viking raiders, and King Alfred changed the level of the river to strand Guthrum and his fleet. In more peaceful times, it becam ...

Slow Sand Filter
Slow sand filters are used in water purification for treating raw water to produce a potable product. They are typically deep, can be rectangular or cylindrical in cross section and are used primarily to treat surface water. The length and breadth of the tanks are determined by the flow rate desired by the filters, which typically have a loading rate of per square metre per hour. Slow sand filters differ from all other filters used to treat drinking water in that they work by using a complex biological film that grows naturally on the surface of the sand. The sand itself does not perform any filtration function but simply acts as a substrate, unlike its counterparts for ultraviolet and pressurized treatments. Although they are often preferred technology in many developing countries because of their low energy requirements and robust performance, they are also used to treat water in some developed countries, such as the UK, where they are used to treat water supplied to London ...

Lea Bridge
Lea Bridge is a district in the London Borough of Hackney and the London Borough of Waltham Forest in London, England. It lies 7 miles (11.3 km) northeast of Charing Cross. The area it takes its name from a bridge built over the River Lea in either 1745 - or sometime after 1757 - and the Lea Bridge Road which leads through the area and across the bridge. The bridge also gives its name to a ward in Waltham Forest ( Lea Bridge) on the eastern, Leyton, bank of the river, and to a ward in Hackney on the Western side of the river, also called Lea Bridge ward. The boundary between the two boroughs runs down the middle of the river at this point. Within Hackney, Lea Bridge Road forms the customary boundary between Upper and Lower Clapton. History In 1582 ''Mill Fields Lane'' ran from Clapton to ''Jeremy's Ferry'' in the Leyton Marshes. At the same spot a timber bridge was built in either 1745, or sometime after 1757. After this, the road became known as ''Lea Bridge Road'', ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
River Lee (England)
The River Lea ( ) is in South East England. It originates in Bedfordshire, in the Chiltern Hills, and flows southeast through Hertfordshire, along the Essex border and into Greater London, to meet the River Thames at Bow Creek. It is one of the largest rivers in London and the easternmost major tributary of the Thames. The river's significance as a major east–west barrier and boundary has tended to obscure its importance as north–south trade route. Below Hertford the river has since medieval times had alterations made to make it more navigable for boats between the Thames and eastern Hertfordshire and Essex, known as the Lee Navigation. This stimulated much industry along its banks. The navigable River Stort, the main tributary, joins it at Hoddesdon. While the lower Lea remains somewhat polluted, its upper stretch and tributaries, classified as chalk streams, are a major source of drinking water for London. An artificial waterway known as the New River, opened in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Old River Lea
The Old River Lea is the former natural channel of the River Lea below Lea Bridge, in the London Borough of Hackney. The Old River forms a large meander from the Middlesex Filter Beds Weir to rejoin the main channel of the River Lee Navigation below Old Ford Lock, just west of the 2012 Olympic stadium. The natural channel is joined by the River Lee Flood Relief Channel, and Dagenham Brook and a number of subsidiary channels to form the semi-tidal Bow Back Rivers, discharging into Bow Creek. The natural channel forms the boundary between the London Boroughs of Hackney and Waltham Forest; and forms the eastern boundary of Hackney Marshes, and historically the western boundary of Leyton Marshes.

Old Ford Lock
Old Ford Lock is a paired lock and weir on the River Lee Navigation, in the London Borough of Tower Hamlets, England. It is at Fish Island in Old Ford and takes its name from the natural ford which used to cross the River Lea. Tidal section Old Ford Lock marks the start of the Hackney Cut – an artificial channel built in the 18th century to cut off a large loop in the natural channel. The natural river rejoins the Navigation at this point – below the lock, having travelled from the Middlesex Filter Beds Weir, just below Lea Bridge; and passing to the east of the Navigation. The Old River Lea (the natural channel), is joined by the River Lee Flood Relief Channel, and Dagenham Brook before connecting to the Bow Back Rivers, which join the tidal Bow Creek. Before the 1930s, there were tide gates installed on this channel to only permit boats to pass when the level in the (at that time) semi-tidal Lee Navigation and tidal Old River were the same. After the 1930s fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weirs On The River Lea
A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. Weirs are also used to control the flow of water for outlets of lakes, ponds, and reservoirs. There are many weir designs, but commonly water flows freely over the top of the weir crest before cascading down to a lower level. Etymology There is no single definition as to what constitutes a weir and one English dictionary simply defines a weir as a small dam, likely originating from Middle English ''were'', Old English ''wer'', derivative of root of ''werian,'' meaning "to defend, dam". Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more navigable by boat. In some locations, the terms dam and weir are synonymous, but normally there is a clear distinction made between the structures. Usually, a dam is designed specifically to impound water behind ...
