Mill Pond
A mill pond (or millpond) is a body of water used as a reservoir for a water-powered mill. Description Mill ponds were often created through the construction of a mill dam or weir (and mill stream) across a waterway. In many places, the common proper name Mill Pond has remained even though the mill has long since gone. It may be fed by a man-made stream, known by several terms including leat and'' mill stream.'' The channel or stream leading from the mill pond is the mill race A mill race, millrace or millrun, mill lade (Scotland) or mill leat (Southwest England) is the current of water that turns a water wheel, or the channel ( sluice) conducting water to or from a water wheel. Compared with the broad waters of a m ..., which together with weirs, dams, channels and the terrain establishing the mill pond, delivers water to the mill wheel to convert potential and/or kinetic energy of the water to mechanical energy by rotating the mill wheel. The production of mechanica ...

Hagley Mill Race
Hagley is a village and civil parish in Worcestershire, England. It is on the boundary of the West Midlands and Worcestershire counties between the Metropolitan Borough of Dudley and Kidderminster. Its estimated population was 7,162 in 2019. Development From the time of the Domesday Book until the 1933 boundary changes, the parish of Hagley extended southwards from the village to include the present parish of Blakedown. The main focus of the village, on the lower slopes of the Clent Hills, was on the outskirts, where Hagley Hall and the parish church of St John the Baptist can be found. The parish register of Hagley is the oldest in England. It dates from 1 December 1538, which was the year in which registers were ordered to be kept in all parishes. Lower Hagley lies downhill and started to expand with the arrival of the Oxford, Worcester and Wolverhampton Railway in 1852 and the eventual building of Hagley railway station. The growth of what is now known as West Hagley initi ...

Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. 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 reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Watermill
A watermill or water mill is a mill that uses hydropower. It is a structure that uses a water wheel or water turbine to drive a mechanical process such as mill (grinding), milling (grinding), rolling, or hammering. Such processes are needed in the production of many material goods, including flour, lumber, paper, textiles, and many metal products. These watermills may comprise gristmills, sawmills, paper mills, textile mills, hammermills, trip hammering mills, rolling mills, and wire drawing mills. One major way to classify watermills is by wheel orientation (vertical or horizontal), one powered by a vertical waterwheel through a Gear train, gear mechanism, and the other equipped with a horizontal waterwheel without such a mechanism. The former type can be further subdivided, depending on where the water hits the wheel paddles, into undershot, overshot, breastshot and pitchback (backshot or reverse shot) waterwheel mills. Another way to classify water mills is by an essential tr ...

Mill Dam
A mill dam (International English) or milldam (US) is a dam constructed on a waterway to create a mill pond. Water passing through a dam's spillway is used to turn a water wheel and provide energy to the many varieties of watermill. By raising the water level so that the overflow has farther to fall, a milldam increases the potential energy that a mill can harness and use for various tasks. Examples {{No sources, section, date=November 2021 Listed are here are some of the many examples of historic milldams and millponds (or place names taken from them). Examples in the United Kingdom include *Bramley Millpond in Bramley, Surrey *Ifield Millpond in Ifield, Crawley, Ifield, West Sussex *Valebridge Millpond on the outskirts of Burgess Hill, West Sussex *Mill Dam, Shapinsay in the Orkney Islands Examples in the United States include *Milldam Rice Mill and Rice Barn in Georgetown County, South Carolina *Al Sabo Preserve, Atwater Millpond in Kalamazoo County, Michigan *Ballardval ...

Weir
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 water 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. There is no single definition as to what constitutes a weir. ''Weir'' can also refer to the skimmer found in most in-ground swimming pools, which controls the flow of water pulled into the filtering system. Etymology The word likely originated from Middle English ''were'', Old English ''wer'', a derivative of the root of the verb ''werian,'' meaning "to defend, dam". The German cognate is ''Wehr'', which means the same as English weir. Function Commonly, weirs are used to prevent flooding, measure water discharge, and help render rivers more Navigability, navigable by boat. In ...

Waterway
A waterway is any Navigability, navigable body of water. Broad distinctions are useful to avoid ambiguity, and disambiguation will be of varying importance depending on the nuance of the equivalent word in other ways. A first distinction is necessary between maritime shipping routes and waterways used by inland water craft. Maritime shipping routes cross oceans and seas, and some lakes, where navigability is assumed, and no engineering is required, except to provide the draft for deep-sea shipping to approach seaports (Channel (geography), channels), or to provide a short cut across an isthmus; this is the function of ship canals. Dredged channels in the sea are not usually described as waterways. There is an exception to this initial distinction, essentially for legal purposes, see under international waters. Where seaports are located inland, they are approached through a waterway that could be termed "inland" but in practice is generally referred to as a "maritime waterway ...

Leat
A leat (; also lete or leet, or millstream) is the name, common in the south and west of England and in Wales, for an artificial watercourse or aqueduct dug into the ground, especially one supplying water to a watermill or its mill pond. Other common uses for leats include delivery of water for hydraulic mining and mineral concentration, for irrigation, to serve a dye works or other industrial plant, and provision of drinking water to a farm or household or as a catchment cut-off to improve the yield of a reservoir. According to the ''Oxford English Dictionary'', ''leat'' is cognate with ''let'' in the sense of "allow to pass through". Other names for the same thing include ''fleam'' (probably a leat supplying water to a mill that did not have a millpool). In parts of northern England, for example around Sheffield, the equivalent word is ''goit''. In southern England, a leat used to supply water for water-meadow irrigation is often called a ''carrier'', ''top carrier'', or ...

Mill Race
A mill race, millrace or millrun, mill lade (Scotland) or mill leat (Southwest England) is the current of water that turns a water wheel, or the channel ( sluice) conducting water to or from a water wheel. Compared with the broad waters of a mill pond, the narrow current is swift and powerful. The race leading to the water wheel on a wide stream or mill pond is called the head race (or headraceDictionary.com, word definition), and the race leading away from the wheel is called the tail raceChamber's Twentieth Century Dictionary, 1968, p=674 (or tailrace). A mill race has many geographically specific names, such as '' leat, lade, flume, goit, penstock''. These words all have more precise definitions and meanings will differ elsewhere. The original undershot waterwheel, described by Vitruvius, was a 'run of the river wheel' placed so a fast flowing stream would press against and turn the bottom of a bucketed wheel. In the first meaning of the term, the millrace was the stream; i ...

Cromford Mill Pond
Cromford () is a village and civil parish in Derbyshire, England, in the valley of the River Derwent between Wirksworth and Matlock. It is north of Derby, south of Matlock and south of Matlock Bath. Cromford is first mentioned in the 11th-century Domesday Book as ''Crumforde'', a berewick (supporting farm) of Wirksworth, and this remained the case throughout the Middle Ages. The population at the 2011 Census was 1,433. It is principally known for its historical connection with Richard Arkwright and the nearby Cromford Mill, which he built outside the village in 1771. Cromford is in the Derwent Valley Mills World Heritage Site. The Cromford mill complex, owned and being restored by the Arkwright Society, was declared by Historic England as "one of the country’s 100 irreplaceable sites". It is also the centrepiece of the Derwent Valley Mills UNESCO World Heritage Site. In 2018, the ''Cromford Mills Creative Cluster and World Heritage Site Gateway Project'' was listed as ...

Hydraulic Engineering
Hydraulic engineering as a sub-discipline of civil engineering is concerned with the flow and conveyance of fluids, principally water and sewage. One feature of these systems is the extensive use of gravity as the motive force to cause the movement of the fluids. This area of civil engineering is intimately related to the design of bridges, dams, channels, canals, and levees, and to both sanitary and environmental engineering. Hydraulic engineering is the application of the principles of fluid mechanics to problems dealing with the collection, storage, control, transport, regulation, measurement, and use of water.Prasuhn, Alan L. ''Fundamentals of Hydraulic Engineering''. Holt, Rinehart, and Winston: New York, 1987. Before beginning a hydraulic engineering project, one must figure out how much water is involved. The hydraulic engineer is concerned with the transport of sediment by the river, the interaction of the water with its alluvial boundary, and the occurrence of scour a ...

Ponds
A pond is a small, still, land-based body of water formed by pooling inside a depression, either naturally or artificially. A pond is smaller than a lake and there are no official criteria distinguishing the two, although defining a pond to be less than in area, less than in depth and with less than 30% of its area covered by emergent vegetation helps in distinguishing the ecology of ponds from those of lakes and wetlands.Clegg, J. (1986). Observer's Book of Pond Life. Frederick Warne, London Ponds can be created by a wide variety of natural processes (e.g. on floodplains as cutoff river channels, by glacial processes, by peatland formation, in coastal dune systems, by beavers). They can simply be isolated depressions (such as a kettle hole, vernal pool, prairie pothole, or simply natural undulations in undrained land) filled by runoff, groundwater, or precipitation, or all three of these. They can be further divided into four zones: vegetation zone, open water, bo ...
