Transvasement
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, the ancient Near East, ancient Rome, ancient Aztec, and ancient Inca. 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 ...

Nabataean
The Nabataeans or Nabateans (; Nabataean Aramaic: , , vocalized as ) were an ancient Arab people who inhabited northern Arabia and the southern Levant. Their settlements—most prominently the assumed capital city of Raqmu (present-day Petra, Jordan)—gave the name ''Nabatene'' () to the Arabian borderland that stretched from the Euphrates to the Red Sea. The Nabateans emerged as a distinct civilization and political entity between the 4th and 2nd centuries BC, with their kingdom centered around a loosely controlled trading network that brought considerable wealth and influence across the ancient world. Described as fiercely independent by contemporary Greco-Roman accounts, the Nabataeans were annexed into the Roman Empire by Emperor Trajan in 106 AD. Nabataeans' individual culture, easily identified by their characteristic finely potted painted ceramics, was adopted into the larger Greco-Roman culture. They converted to Christianity during the Byzantine period. They h ...

Petra
Petra (; "Rock"), originally known to its inhabitants as Raqmu (Nabataean Aramaic, Nabataean: or , *''Raqēmō''), is an ancient city and archaeological site in southern Jordan. Famous for its rock-cut architecture and water conduit systems, Petra is also called the "Rose City" because of the colour of the sandstone from which it is carved. The city is one of the New 7 Wonders of the World and a UNESCO World Heritage Site. The area around Petra has been inhabited from as early as 7000 BC, and was settled by the Nabataeans, a nomadic Arab people, in the 4th century BC. Petra would later become the capital city of the Nabataean Kingdom in the second century BC. The Nabataeans invested in Petra's proximity to the incense trade routes by establishing it as a major regional trading hub, which gained them considerable revenue. Unlike their enemies, the Nabataeans were accustomed to living in the barren deserts and thus were able to defend their kingdom. They were particularly sk ...

Qanāt
A qanāt () or kārīz () is a water supply system that was developed in ancient Iran for the purpose of transporting usable water to the surface from an aquifer or a well through an underground aqueduct. Originating approximately 3,000 years ago, its function is essentially the same across the Middle East and North Africa, but it is known by a variety of regional names beyond today's Iran, including: kārēz in Afghanistan and Pakistan; foggāra in Algeria; khettāra in Morocco; falaj in Oman and the United Arab Emirates; and ʿuyūn in Saudi Arabia. In addition to those in Iran, the largest extant and functional qanats are located in Afghanistan, Algeria, China (i.e., the Turpan water system), Oman, and Pakistan. Proving crucial to water supply in areas with hot and dry climates, a qanat enables water to be transported over long distances by largely eliminating the risk of much of it evaporating on the journey. The system also has the advantage of being fairly resistant to nat ...

Iron Age
The Iron Age () is the final epoch of the three historical Metal Ages, after the Chalcolithic and Bronze Age. It has also been considered as the final age of the three-age division starting with prehistory (before recorded history) and progressing to protohistory (before written history). In this usage, it is preceded by the Stone Age (subdivided into the Paleolithic, Mesolithic and Neolithic) and Bronze Age. These concepts originated for describing Iron Age Europe and the ancient Near East. In the archaeology of the Americas, a five-period system is conventionally used instead; indigenous cultures there did not develop an iron economy in the pre-Columbian era, though some did work copper and bronze. Indigenous metalworking arrived in Australia with European contact. Although meteoric iron has been used for millennia in many regions, the beginning of the Iron Age is defined locally around the world by archaeological convention when the production of Smelting, smelted iron (espe ...

Tungabhadra River
The Tungabhadra River () starts and flows through the state of Karnataka, India, for most of its course, then through Andhra Pradesh where it ultimately joins the Krishna River near Murvakonda. The Tungabhadra derives its name from two streams, the Tunga, about long, and the Bhadra, about long, which rise in the Western Ghats(Sahyadri mountains). The river after the confluence of the two streams in Koodali near Shimoga runs for about till it joins the river Krishna at Sangamaleshwaram in Andhra Pradesh.
