Horsepower (hp) is a unit of measurement of power, or the rate at which work is done, usually in reference to the output of engines or motors. There are many different standards and types of horsepower. Two common definitions used today are the mechanical horsepower, which is about 745.7 watts, and the metric horsepower, which is approximately 735.5 watts.
The River Ant is a tributary river of the River Bure in the county of Norfolk, England. It is 27 kilometres (17 mi) long, and has an overall drop of 27 metres from source to mouth. It is said that the Ant was formerly known as the River Smale and that this is the origin of the name of the village of Smallburgh.
The Old Bedford River is an artificial, partial diversion of the waters of the River Great Ouse in the Fens of Cambridgeshire, England. It was named after the fourth Earl of Bedford who contracted with the local Commission of Sewers to drain the Great Level of the Fens beginning in 1630. It provided a steeper and shorter path for the waters of the Great Ouse, and was embanked to prevent them flooding the low ground of the South Fens. Throughout the project, the Earl and his Adventurers faced disruption from those who were opposed to drainage schemes. The project was deemed to have succeeded in draining the fens in 1637, but that decision was reversed in 1638. After a lull during the English Civil War, when much of the work was damaged, the Dutch engineer Cornelius Vermuyden worked with William Russell, the fifth Earl of Bedford to complete the drainage. Disruption and unrest continued while the work was carried out, resulting in the Adventurers employing armed guards. A second river, the New Bedford River, was cut parallel to the first channel, which then became the Old Bedford River. At some point, the Old Bedford River was split into two parts, when the upper section was diverted into the River Delph at Welches Dam, and the lower section was joined to the Counter Drain. Both parts retain the name, but are not connected to each other. The area between the two Bedford rivers acts as a large washland, which holds floodwater when the river channels cannot cope with the volume of water in them.
The New Bedford River, also known as the Hundred Foot Drain because of the distance between the tops of the two embankments on either side of the river, is a navigable man-made cut-off or by-pass channel of the River Great Ouse in the Fens of Cambridgeshire, England. It provides an almost straight channel between Earith and Denver Sluices. It is tidal, with reverse tidal flow being clearly visible at Welney, some 19 miles (31 km) from the sea.
Stretham Old Engine is a steam-powered engine just south of Stretham in Cambridgeshire, England, that was used to pump water from flood-affected areas of The Fens back into the River Great Ouse. It is one of only three surviving drainage engines in East Anglia, and is a Grade II* listed building.
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.
Bourne Eau is a short river which rises from an artesian spring in the town of Bourne in Lincolnshire, England, and flows in an easterly direction to join the River Glen at Tongue End. Within the town, it once powered three water mills, one of which is now a heritage centre. At Eastgate, it becomes much wider as it was navigable in the 18th and 19th centuries, and this was the location of the terminal basin. Below the town it is an embanked river, as its normal level is higher than that of the surrounding Fens. Navigation ceased in the 1860s and the river now forms an important part of the drainage system that enables the surrounding fen land to be used for agriculture.
An axial-flow pump, or AFP, is a common type of pump that essentially consists of a propeller in a pipe. The propeller can be driven directly by a sealed motor in the pipe or by electric motor or petrol/diesel engines mounted to the pipe from the outside or by a right-angle drive shaft that pierces the pipe.
Hatfield Chase is a low-lying area in South Yorkshire and North Lincolnshire, England, which was often flooded. It was a royal hunting ground until Charles I appointed the Dutch engineer Cornelius Vermuyden to drain it in 1626. The work involved the re-routing of the Rivers Don, Idle, and Torne, and the construction of drainage channels. It was not wholly successful, but changed the whole nature of a wide swathe of land including the Isle of Axholme, and caused legal disputes for the rest of the century. The civil engineer John Smeaton looked at the problem of wintertime flooding in the 1760s, and some remedial work was carried out.
Burnt Fen is an area of low-lying land crossed by the A1101 road between Littleport in Cambridgeshire and Mildenhall in Suffolk, England. It is surrounded on three sides by rivers, and consists of prime agricultural land, with sparse settlement. It is dependent on pumped drainage to prevent it from flooding.
Whittlesea Mere was an area of open water in the Fenland area of the county of Huntingdonshire, England. The mere occupied the land southeast of Yaxley Fen, south of Farcet Fen and north of Holme Fen. The town of Whittlesey lay to the northeast.
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 97 square miles (250 km2). In total there are over 438 miles (705 km) of drainage ditches, of which under 60 miles (97 km) 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.
Pode Hole is a village in South Holland, Lincolnshire, England. It is 2 miles (3.2 km) from Spalding and a similar distance from Bourne. The village lies at the confluence of several drainage channels, where two pumping stations discharge water into Vernatt's Drain from land in Deeping Fen to the South and West. Water from Pinchbeck South Fen to the North is also lifted into Vernatt's Drain. The village arose to service the pumping stations.
The Pinchbeck Engine is a drainage engine, a rotative beam engine built in 1833 to drain Pinchbeck Marsh, to the north of Spalding, Lincolnshire, in England. Until it was shut down in 1952, the engine discharged into the Blue Gowt which joins the River Glen at Surfleet Seas End.
Guthram Gowt is a small settlement in the South Holland district of Lincolnshire, England. It is situated 5 miles (8 km) both east from Bourne and west from Spalding, and at a bend in the River Glen.
The Dogdyke Engine is a drainage engine near Tattershall, Lincolnshire, in England. The drainage of 2,500 acres (1,012 ha) of land around Tattershall was authorised in 1796, and came under the control of the Witham Third District commissioners in 1844
Deeping Fen is a low-lying area in the South Holland district of Lincolnshire, England, which covers approximately 47 square miles (120 km2). It is bounded by the River Welland and the River Glen, and is extensively drained, but the efficient drainage of the land exercised the minds of several of the great civil engineers of the 17th and 18th centuries.
Witham First District IDB is an English internal drainage board which was set up under the terms of the Land Drainage Act 1930. The Board inherited the responsibilities of the Witham General Drainage Commissioners, who were first constituted by an Act of Parliament of 1762. They manage the land drainage of an area to the west of the River Witham, between Lincoln and Dogdyke, which includes the valley of the River Slea to above Sleaford.
South Holland IDB is an English internal drainage board set up under the terms of the Land Drainage Act 1930. It has responsibility for the land drainage of 148.43 square miles (384.4 km2) of low-lying land in South Lincolnshire. It is unusual as its catchment area is the same as the area of the drainage district, and so it does not have to deal with water flowing into the area from surrounding higher ground. No major rivers flow through the area, although the district is bounded by the River Welland to the west and the River Nene to the east.
Witham Third District IDB is an English internal drainage board set up under the terms of the Land Drainage Act 1930. The Board inherited the responsibilities of the Witham General Drainage Commissioners, who were first constituted by an Act of Parliament of 1762. They manage the land drainage of an area to the north and east of the River Witham, between Lincoln and Dogdyke, which includes the valley of the River Bain to above Hemingby, and the valleys of Barlings Eau and most of its tributaries, to the north east of Lincoln.
