Canal Pound
A canal pound (from impound), reach, or level (American usage), is the stretch of level water impounded between two canal locks. Canal pounds can vary in length from the non-existent, where two or more immediately adjacent locks form a lock staircase, to many kilometres/miles. The longest canal pound in the United Kingdom is between the stop lock on the Trent and Mersey Canal at Preston Brook (Dutton Stop Lock No 76) and the start of the Leeds and Liverpool Canal near Leigh (Poolstock Bottom Lock No 2), a distance of . Another long pound is on the Kennet and Avon Canal between Wootton Rivers Bottom Lock and Caen Hill top lock. The longest level on the Erie Canal in New York was the 60 mile level (actually ) between Henrietta and Lockport. History Pounds came into being with the development of pound locks to replace the earlier flash locks. A key feature of pound locks was that the intervening level between locks remained largely constant, as opposed to the variable levels created ...

Summit Level Of Morris Canal From HABS
A summit is a point on a surface that is higher in elevation than all points immediately adjacent to it. The topographic terms acme, apex, peak (mountain peak), and zenith are synonymous. The term (mountain top) is generally used only for a mountain peak that is located at some distance from the nearest point of higher elevation. For example, a big, massive rock next to the main summit of a mountain is not considered a summit. Summits near a higher peak, with some prominence or isolation, but not reaching a certain cutoff value for the quantities, are often considered ''subsummits'' (or ''subpeaks'') of the higher peak, and are considered part of the same mountain. A pyramidal peak is an exaggerated form produced by ice erosion of a mountain top. Summit may also refer to the highest point along a line, trail, or route. The highest summit in the world is Mount Everest with a height of above sea level. The first official ascent was made by Tenzing Norgay and Sir Edmund Hillary. ...

Morris Canal
The Morris Canal (1829–1924) was a common carrier anthracite coal canal across northern New Jersey that connected the two industrial canals at Easton, Pennsylvania across the Delaware River from its western terminus at Phillipsburg, New Jersey to New York Harbor and New York City via its eastern terminals in Newark and on the Hudson River in Jersey City. The canal was sometimes called the Morris and Essex Canal, in error, due to confusion with the nearby and unrelated Morris and Essex Railroad. With a total elevation change of more than , the canal was considered an ingenious technological marvel for its use of water-driven inclined planes, the first in the United States, to cross the northern New Jersey hills. It was built primarily to move coal to industrializing eastern cities that had stripped their environs of wood. Completed to Newark in 1831, the canal was extended eastward to Jersey City between 1834 and 1836. In 1839, hot blast technology was married to blast furn ...

Lough Neagh
Lough Neagh ( ) is a freshwater lake in Northern Ireland and is the largest lake in the island of Ireland, the United Kingdom and the British Isles. It has a surface area of and supplies 40% of Northern Ireland's water. Its main inflows come from the Upper River Bann and River Blackwater, and its main outflow is the Lower River Bann. Its name comes from Irish , meaning " Eachaidh's lake".Deirdre Flanagan and Laurance Flanagan, Irish Placenames, (Gill & Macmillan Ltd, 1994) The lough is owned by the Earl of Shaftesbury and managed by Lough Neagh Partnership Ltd. Geography With an area of , it is the British Isles' largest lake by area and is ranked 33rd in the list of largest lakes of Europe. Located west of Belfast, it is about long and wide. It is very shallow around the margins and the average depth in the main body of the lake is about , although at its deepest the lough is about deep.

Newry
Newry (; ) is a city in Northern Ireland, divided by the Clanrye river in counties Armagh and Down, from Belfast and from Dublin. It had a population of 26,967 in 2011. Newry was founded in 1144 alongside a Cistercian monastery, although there are references to earlier settlements in the area, and is one of Ireland's oldest towns. The city is an entry to the " Gap of the North", from the border with the Republic of Ireland. It grew as a market town and a garrison and became a port in 1742 when it was linked to Lough Neagh by the first summit-level canal built in Ireland or Great Britain. A cathedral city, it is the episcopal seat of the Roman Catholic Diocese of Dromore. In 2002, as part of Queen Elizabeth's Golden Jubilee celebrations, Newry was granted city status along with Lisburn. Name The name Newry is an anglicization of ''An Iúraigh'', an oblique form of ''An Iúrach'', which means "the grove of yew trees". The modern Irish name for Newry is ''An tIúr'' ( ...

Newry Canal
The Newry Canal, located in Northern Ireland, was built to link the Tyrone coalfields (via Lough Neagh and the River Bann) to the Irish Sea at Carlingford Lough near Newry. It was the first summit level canal to be built in Ireland or Great Britain, and pre-dated the more famous Bridgewater Canal by nearly thirty years and Sankey Canal by fifteen years. It was authorised by the Commissioners of Inland Navigation for Ireland, and was publicly funded. It was opened in 1742, but there were issues with the lock construction, the width of the summit level and the water supply. Below Newry, the Newry Ship Canal was opened in 1769, and both Newry and the canal flourished. By 1800, the canal was in a poor condition, and another £57,000 of public money was spent refurbishing it over the following ten years. Closures during the refurbishment resulted in a loss of traffic, which did not fully recover. In 1829, both canals were transferred to a private company, who spent £80,000 on impr ...

Hollingworth Lake
Hollingworth Lake is a reservoir at Smithy Bridge in Littleborough, Greater Manchester, England. It was originally built as the main water source for the Rochdale Canal, but developed as a tourist resort from the 1860s. Hotels were built around it, helped by the arrival of the railway in 1839, which brought day-trippers and weekend visitors from Manchester, Bradford and Leeds. The popularity of the lake as a resort declined in the early twentieth century and the area was used as an army camp in the First World War. The canal company sold the reservoir to Oldham and Rochdale Corporations for water supply in 1923. After the Second World War, boating rights were bought by Rochdale Council, who developed the area into the Hollingworth Lake Country Park in 1974. There has been a steady increase in facilities since, and it is now a thriving centre for water sports and other activities. Hollingworth Lake Rowing Club has been in continuous existence since 1872.

Manchester
Manchester () is a city in Greater Manchester, England. It had a population of 552,000 in 2021. It is bordered by the Cheshire Plain to the south, the Pennines to the north and east, and the neighbouring city of Salford to the west. The two cities and the surrounding towns form one of the United Kingdom's most populous conurbations, the Greater Manchester Built-up Area, which has a population of 2.87 million. The history of Manchester began with the civilian settlement associated with the Roman fort ('' castra'') of ''Mamucium'' or ''Mancunium'', established in about AD 79 on a sandstone bluff near the confluence of the rivers Medlock and Irwell. Historically part of Lancashire, areas of Cheshire south of the River Mersey were incorporated into Manchester in the 20th century, including Wythenshawe in 1931. Throughout the Middle Ages Manchester remained a manorial township, but began to expand "at an astonishing rate" around the turn of the 19th century. Manchest ...

Pennines
The Pennines (), also known as the Pennine Chain or Pennine Hills, are a range of uplands running between three regions of Northern England: North West England on the west, North East England and Yorkshire and the Humber on the east. Commonly described as the "backbone of England", the range stretches northwards from the Peak District at the southern end, through the South Pennines, Yorkshire Dales and North Pennines to the Tyne Gap, which separates the range from the Border Moors and Cheviot Hills across the Anglo-Scottish border, although some definitions include them. South of the Aire Gap is a western spur into east Lancashire, comprising the Rossendale Fells, West Pennine Moors and the Bowland Fells in North Lancashire. The Howgill Fells and Orton Fells in Cumbria are sometimes considered to be Pennine spurs to the west of the range. The Pennines are an important water catchment area with numerous reservoirs in the head streams of the river valleys. The North Pennin ...

Rochdale Canal
The Rochdale Canal is in Northern England, between Manchester and Sowerby Bridge, part of the connected system of the canals of Great Britain. Its name refers to the town of Rochdale through which it passes. The Rochdale is a broad canal because its locks are wide enough to allow vessels of width. The canal runs for across the Pennines from the Bridgewater Canal at Castlefield Basin in Manchester to join the Calder and Hebble Navigation at Sowerby Bridge in West Yorkshire. As built, the canal had 92 locks. Whilst the traditional lock numbering has been retained on all restored locks, and on the relocated locks, the canal now has 91. Locks 3 and 4 have been replaced with a single deep lock, Tuel Lane Lock, which is numbered 3/4. History The Rochdale Canal was conceived in 1776, when a group of 48 men from Rochdale raised £237 and commissioned James Brindley to conduct a survey of possible routes between Sowerby Bridge and Manchester. Brindley proposed a route similar to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pumping Station
Pumping stations, also called pumphouses in situations such as well drilling, drilled wells and drinking water, are facilities containing pumps and equipment for pumping fluids from one place to another. They are used for a variety of infrastructure systems, such as the supply of water to canals, the drainage of low-lying land, and the removal of sewage to processing sites. A pumping station is an integral part of a pumped-storage hydroelectricity installation. Canal water supply In countries with canal systems, pumping stations are also frequent. Because of the way the system of canal locks work, water is lost from the upper part of a canal each time a vessel passes through. Also, most lock gates are not watertight, so some water leaks from the higher levels of the canal to those lower down. Obviously, the water has to be replaced or eventually the upper levels of the canal would not hold enough water to be navigable. Canals are usually fed by diverting water from streams and ...

Reservoir (water)
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin of the re ...
