The River Don is a river in South Yorkshire and the East Riding of Yorkshire, England. It rises in the Pennines, west of Dunford Bridge, and flows for 69 miles (111 km) eastwards, through the Don Valley, via Penistone, Sheffield, Rotherham, Mexborough, Conisbrough, Doncaster and Stainforth. It originally joined the Trent, but was re-engineered by Cornelius Vermuyden as the Dutch River in the 1620s, and now joins the River Ouse at Goole. Don Valley is a UK parliamentary constituency near the Doncaster stretch of the river.
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.
The River Loxley is a river in the City of Sheffield, South Yorkshire, England. Its source is a series of streams which rise some 10 miles (16 km) to the north-west of Sheffield on Bradfield Moors, flowing through Bradfield Dale to converge at Low Bradfield. It flows easterly through Damflask Reservoir and is joined by Storrs Brook at Storrs, near Stannington, and the River Rivelin at Malin Bridge, before flowing into the River Don at Owlerton, in Hillsborough. The Loxley valley provided the initial course of the Great Sheffield Flood, which happened after the Dale Dyke Dam collapsed shortly before its completion in March 1864.
A body of water or waterbody is any significant accumulation of water on the surface of Earth or another planet. The term most often refers to oceans, seas, and lakes, but it includes smaller pools of water such as ponds, wetlands, or more rarely, puddles. A body of water does not have to be still or contained; rivers, streams, canals, and other geographical features where water moves from one place to another are also considered bodies of water.
The Gatun Dam is a large earthen dam across the Chagres River in Panama, near the town of Gatun. The dam, constructed between 1907 and 1913, is a crucial element of the Panama Canal; it impounds the artificial Gatun Lake, which in turn carries ships 33 kilometres (21 mi) of their transit across the Isthmus of Panama. In addition, a hydro-electric generating station at the dam generates electricity which is used to operate the locks and other equipment in the canal.
Teddington Lock is a complex of three locks and a weir on the River Thames between Ham and Teddington in the London Borough of Richmond upon Thames, England. Historically in Middlesex, it was first built in 1810.
A canal pound, reach, or level, 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 Little Don River also known as the Porter, is a tributary of the River Don in South Yorkshire, England. Arising on the Langsett Moors in the northern Peak District, the Little Don River feeds the Langsett and Underbank Reservoirs. It runs through the town of Stocksbridge before joining the River Don.
The Payette River is an 82.7-mile-long (133.1 km) river in southwestern Idaho and is a major tributary of the Snake River.
The Sihl is a Swiss river that rises near the Druesberg mountain in the canton of Schwyz, and eventually flows into the Limmat in the centre of the city of Zürich. It has a length of 73 km (45 mi), including the Sihlsee reservoir, through which the river flows. Water is abstracted from the river at the Sihlsee, leading to decreased downstream water flows and a consequent reduction in water quality.
"Reservoir" as a technical term, most commonly refers to 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.
Nagarjuna Sagar Dam is a masonry dam across the Krishna River at Nagarjuna Sagar which straddles the border between Nalgonda district in Telangana and Palnadu district in Andhra Pradesh. The dam provides irrigation water to the Nalgonda, Suryapet, Krishna, NTR, Bapatla, Eluru, Palnadu, Khammam, West Godavari, Guntur, and Prakasam districts along with electricity generation.
River engineering is a discipline of civil engineering which studies human intervention in the course, characteristics, or flow of a river with the intention of producing some defined benefit. People have intervened in the natural course and behaviour of rivers since before recorded history—to manage the water resources, to protect against flooding, or to make passage along or across rivers easier. Since the Yuan Dynasty and Ancient Roman times, rivers have been used as a source of hydropower. From the late 20th century, river engineering has had environmental concerns broader than immediate human benefit and some river engineering projects have been concerned exclusively with the restoration or protection of natural characteristics and habitats.
The Gabčíkovo–Nagymaros Dams is a large barrage project on the Danube. It was initiated by the Budapest Treaty of 16 September 1977 between the Czechoslovak Socialist Republic and the Hungarian People's Republic. The project aimed at preventing catastrophic floods, improving river navigability and producing clean electricity.
The Ware River is a 35.4-mile-long (57.0 km) river in central Massachusetts. It has two forks, its West Branch, which begins in Hubbardston, Massachusetts, and its East Branch, which begins in Westminster, Massachusetts. The Ware River flows southwest through the middle of the state, joins the Quaboag River at Three Rivers, Massachusetts, to form the Chicopee River on its way to the Connecticut River.
Pollution of the Ganges, the largest river in India, poses significant threats to human health and the larger environment. The river, which is severely polluted with human waste and industrial contaminants, provides water to about 40% of India's population across 11 states, serving an estimated population of 500 million people, which is more than any other river in the world.
The Čunovo Water Sports Centre is an artificial whitewater slalom course in Slovakia, on an island in the Danube river, 14 km southeast of Bratislava, near the village of Čunovo. It is powered by flow diversion from the Čunovo dam. Since 1997, it has hosted a full schedule of local, regional, and international competitions, including multiple World Cup races, 2 European Championships and the 2011 World Championships.
Low-head hydropower refers to the development of hydroelectric power where the head is typically less than 20 metres, although precise definitions vary. Head is the vertical height measured between the hydro intake water level and the water level at the point of discharge. Using only a low head drop in a river or tidal flows to create electricity may provide a renewable energy source that will have a minimal impact on the environment. Since the generated power is a function of the head these systems are typically classed as small-scale hydropower, which have an installed capacity of less than 5MW.
A controlled lake is both a general and specific term to describe a body of water. In its general sense it describes a lake or reservoir which has its water level controlled by some form of dam. In the specific, it refers to three small lakes within the New York City water supply system's Croton Watershed lying within central Putnam County in the state's far southwestern corner.
