Roman Aqueduct
The Romans constructed aqueducts throughout their Republic and later Empire, to bring water from outside sources into cities and towns. Aqueduct water supplied public baths, latrines, fountains, and private households; it also supported mining operations, milling, farms, and gardens. Aqueducts moved water through gravity alone, along a slight overall downward gradient within conduits of stone, brick, concrete or lead; the steeper the gradient, the faster the flow. Most conduits were buried beneath the ground and followed the contours of the terrain; obstructing peaks were circumvented or, less often, tunneled through. Where valleys or lowlands intervened, the conduit was carried on bridgework, or its contents fed into high-pressure lead, ceramic, or stone pipes and siphoned across. Most aqueduct systems included sedimentation tanks, which helped to reduce any water-borne debris. Sluices, ''castella aquae'' (distribution tanks) and stopcocks regulated the supply to individual de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aqueduct (water Supply)
An aqueduct is a watercourse constructed to carry water from a source to a distribution point far away. In modern engineering, the term ''aqueduct'' is used for any system of pipes, ditches, canals, tunnels, and other structures used for this purpose. The term ''aqueduct'' also often refers specifically to a bridge carrying an artificial watercourse. Aqueducts were used in ancient Greece, ancient Egypt, and ancient Rome. The simplest aqueducts are small ditches cut into the earth. Much larger channels may be used in modern aqueducts. Aqueducts sometimes run for some or all of their path through tunnels constructed underground. Modern aqueducts may also use pipelines. Historically, agricultural societies have constructed aqueducts to irrigate crops and supply large cities with drinking water. Etymology The word ''aqueduct'' is derived from the Latin words (''water'') and (''led'' or ''guided''). Ancient aqueducts Although particularly associated with the Romans, aqueducts we ...

Puquios
Puquios (from Quechua ''pukyu'' meaning source, spring, or water well) are ancient systems of subterranean aqueducts which allow water to be transported over long distances in hot dry climates without loss of much of the water to evaporation. Puquios are found in the coastal deserts of southern Peru, especially in the Nazca region, and northern Chile. Forty-three puquios in the Nazca region were still in use in the early 21st century and relied upon to bring fresh water for irrigation and domestic use into desert settlements. The origin and dating of the Nazca puquios is disputed, although some archaeologists have estimated that their construction began about 500 CE by indigenous people of the Nazca culture. The technology of the puquios is similar to that of the Qanats of Iran and other desert areas of Asia and Europe, including Spain. A few puquios in northern Chile and in other parts of Peru were probably constructed at the initiative of the Spanish after the conquest ...

Aqueduct (bridge)
Aqueducts (or water bridges) are bridges constructed to convey watercourses across gaps such as valleys or ravines. The term ''aqueduct'' may also be used to refer to the Aqueduct (water supply), entire watercourse, as well as the bridge. Large navigable aqueducts are used as transport links for boats or ships. Aqueducts must span a crossing at the same level as the watercourses on each end. The word is derived from the Latin language, Latin ' ("water") and ' ("to lead"), therefore meaning "to lead water". A modern version of an aqueduct is a pipeline bridge. They may take the form of tunnels, networks of surface channels and canals, covered clay pipes or monumental bridges. Ancient bridges for water Although particularly associated with the Roman aqueduct, Romans, aqueducts were likely first used by the Minoans around 2000 BCE. The Minoans had developed what was then an extremely advanced irrigation system, including several aqueducts. In the seventh century BCE, the Neo-Ass ...

Aqueduct, New York
Aqueduct is a hamlet in the Town of Niskayuna, Schenectady County, New York, United States. Its center is at the south end of the bridge of New York State Route 146 (Balltown Road) over the Mohawk River, that connects Schenectady County to the south and Saratoga County to the north. It was formerly a transportation hub. Alexander's Bridge across the Mohawk (see the map) antedated the Aqueduct. A new Route 146 steel highway bridge, with board pavement, parallel to the Aqueduct was built in the early 20th century. A Schenectady trolley line ended there, the line also serving Luna Park, just over the river in Rexford. There was, in Aqueduct, a staffed station of the Troy & Schenectady Railroad, which operated from 1841 to 1932. The navigable aqueduct which gave the name was not part of a water supply. It was, rather, the water bridge that allowed boats on the Erie Canal, and the mules towing them, to cross over the Mohawk River, which ran beneath the water bridge or aqueduct. The ...

Levada
A levada is an irrigation channel or aqueduct specific to the Portuguese Atlantic region of Madeira. History In Madeira, the levadas originated out of the necessity of bringing large amounts of water from the west and northwest of the island to the drier southeast, which is more conducive to habitation and agriculture, such as sugar cane production. They were used in the past also by women to wash clothes in areas where running water to homes was not available. The idea of this style of water channel was brought to Portugal by the Moors during the time of al-Andalus (dubious) . Similar examples can still be found in Iberia, such as some Acequias in Spain. In the sixteenth century the Portuguese started building levadas to carry water to the agricultural regions. The most recent were made in the 1940s. Madeira is very mountainous, and building the levadas was often difficult. Many are cut into the sides of mountains, and it was also necessary to dig of tunnels. Levadas to ...

Aqueduct Of Segovia
The Aqueduct of Segovia () is a Roman aqueduct in Segovia, Spain. It was built around the first century AD to channel water from springs in the mountains away to the city's fountains, public baths and private houses, and was in use until 1973. Its elevated section, with its complete arcade of 167 arches, is one of the best-preserved Roman aqueduct bridges and the foremost symbol of Segovia, as evidenced by its presence on the city's coat of arms. The Old Town of Segovia and the aqueduct, were declared a UNESCO World Heritage Site in 1985. History As the aqueduct lacks a legible inscription (one was apparently located in the structure's ''attic'', or top portion), the date of construction cannot be definitively determined. The general date of the Aqueduct's construction was long a mystery, although it was thought to have been during the 1st century AD, during the reigns of the Emperors Domitian, Nerva, and Trajan. At the end of the 20th century, Géza Alföldy deciphered the te ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Acequia
An acequia () or séquia () is a community-operated watercourse used in Spain and former Spanish colonies in the Americas for irrigation. Particularly in Spain, the Andes, northern Mexico, and the modern-day American Southwest particularly northern New Mexico and southern Colorado, acequias are usually historically engineered canals that carry snow runoff or river water to distant fields. Examples of acequias in New Mexico have lengthy historical roots to Pueblo and Hispano communities, and they are incorporated into traditions including the matachines, life in the Rio Grande Bosque of the Albuquerque metropolitan area, and pilgrimages to El Santuario de Chimayo. The term can also refer to the long central pool in a Moorish garden, such as the Generalife in the Alhambra in Southern Iberia. Overview The Spanish word (and Catalan ) comes from Classical Arabic , which has the double meaning of 'the water conduit' or 'one that bears water' and the 'barmaid' (from , 'to g ...

Navigable Aqueduct
Navigable aqueducts (sometimes called water bridges) are bridge structures that carry navigable waterway canals over other rivers, valleys, railways or roads. They are primarily distinguished by their size, carrying a larger cross-section of water than most water-supply aqueducts. Roman aqueducts were used to transport water and were created in Ancient Rome. The long steel Briare aqueduct carrying the Canal latéral à la Loire over the River Loire was built in 1896. It was ranked as the longest navigable aqueduct in the world for more than a century, until the Magdeburg Water Bridge in Germany took the title in the early 21st century. Early aqueducts such as the three on the Canal du Midi had stone or brick arches, the longest span being on the Cesse Aqueduct, built in 1690. But, the weight of the construction to support the trough with the clay or other lining to make it waterproof made these structures clumsy. In 1796 Longdon-on-Tern Aqueduct, the first large cast iron aqu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
