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 indivi ...

Ancient Greece
Ancient Greece ( el, Ἑλλάς, Hellás) was a northeastern Mediterranean Sea, Mediterranean civilization, existing from the Greek Dark Ages of the 12th–9th centuries BC to the end of Classical Antiquity, classical antiquity ( AD 600), that comprised a loose collection of culturally and linguistically related polis, city-states and other territories. Most of these regions were officially unified only once, for 13 years, under Alexander the Great's Macedonian empire, empire from 336 to 323 BC (though this excludes a number of Greek city-states free from Alexander's jurisdiction in the western Mediterranean, around the Black Sea, Cyprus, and Cyrenaica). In Western history, the era of classical antiquity was immediately followed by the Early Middle Ages and the Byzantine period. Roughly three centuries after the Late Bronze Age collapse of Mycenaean Greece, Greek urban poleis began to form in the 8th century BC, ushering in the Archaic Greece, Archaic period and Greek colonis ...

Etruscan Civilization
The Etruscan civilization () was developed by a people of Etruria in ancient Italy with a common language and culture who formed a federation of city-states. After conquering adjacent lands, its territory covered, at its greatest extent, roughly what is now Tuscany, western Umbria, and northern Lazio, as well as what are now the Po Valley, Emilia-Romagna, south-eastern Lombardy, southern Veneto, and western Campania. The earliest evidence of a culture that is identifiably Etruscan dates from about 900BC. This is the period of the Iron Age Villanovan culture, considered to be the earliest phase of Etruscan civilization, which itself developed from the previous late Bronze Age Proto-Villanovan culture in the same region. Etruscan civilization endured until it was assimilated into Roman society. Assimilation began in the late 4thcenturyBC as a result of the Roman–Etruscan Wars; it accelerated with the grant of Roman citizenship in 90 BC, and became complete in 27 BC, w ...

River Tiber
The Tiber ( ; it, Tevere ; la, Tiberis) is the third-longest river in Italy and the longest in Central Italy, rising in the Apennine Mountains in Emilia-Romagna and flowing through Tuscany, Umbria, and Lazio, where it is joined by the River Aniene, to the Tyrrhenian Sea, between Ostia and Fiumicino. It drains a basin estimated at . The river has achieved lasting fame as the main watercourse of the city of Rome, which was founded on its eastern banks. The river rises at Mount Fumaiolo in central Italy and flows in a generally southerly direction past Perugia and Rome to meet the sea at Ostia. Known in ancient times (in Latin) as ''flavus'' ("the blond"), in reference to the yellowish colour of its water, the Tiber has advanced significantly at its mouth, by about , since Roman times, leaving the ancient port of Ostia Antica inland."Tiber River".

Cistern
A cistern (Middle English ', from Latin ', from ', "box", from Greek ', "basket") is a waterproof receptacle for holding liquids, usually water. Cisterns are often built to catch and store rainwater. Cisterns are distinguished from wells by their waterproof linings. Modern cisterns range in capacity from a few litres to thousands of cubic metres, effectively forming covered reservoirs. Origins Early domestic and agricultural use Waterproof lime plaster cisterns in the floors of houses are features of Neolithic village sites of the Levant at, for instance, Ramad and Lebwe, and by the late fourth millennium BC, as at Jawa in northeastern Lebanon, cisterns are essential elements of emerging water management techniques in dry-land farming communities. The Ancient Roman impluvium, a standard feature of the domus house, generally had a cistern underneath. The impluvium and associated structures collected, filtered, cooled, and stored the water, and also cooled and ventila ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Groundwater
Groundwater is the water present beneath Earth's surface in rock and soil pore spaces and in the fractures of rock formations. About 30 percent of all readily available freshwater in the world is groundwater. A unit of rock or an unconsolidated deposit is called an aquifer when it can yield a usable quantity of water. The depth at which soil pore spaces or fractures and voids in rock become completely saturated with water is called the water table. Groundwater is recharged from the surface; it may discharge from the surface naturally at springs and seeps, and can form oases or wetlands. Groundwater is also often withdrawn for agricultural, municipal, and industrial use by constructing and operating extraction wells. The study of the distribution and movement of groundwater is hydrogeology, also called groundwater hydrology. Typically, groundwater is thought of as water flowing through shallow aquifers, but, in the technical sense, it can also contain soil moisture, permafros ...

Dionysius Of Halicarnassus
Dionysius of Halicarnassus ( grc, Διονύσιος Ἀλεξάνδρου Ἁλικαρνασσεύς, ; – after 7 BC) was a Greek historian and teacher of rhetoric, who flourished during the reign of Emperor Augustus. His literary style was ''atticistic'' – imitating Classical Attic Greek in its prime. Dionysius' opinion of the necessity of a promotion of paideia within education, from true knowledge of classical sources, endured for centuries in a form integral to the identity of the Greek elite. Life He was a Halicarnassian. At some time after the end of the civil wars he moved to Rome, and spent twenty-two years studying Latin and literature and preparing materials for his history. During this period, he gave lessons in rhetoric, and enjoyed the society of many distinguished men. The date of his death is unknown. In the 19th century, it was commonly supposed that he was the ancestor of Aelius Dionysius of Halicarnassus. Works His major work, entitled (), ...

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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
De Aquaeductu
( en, On aqueducts) is a two-book official report given to the emperor Nerva or Trajan on the state of the aqueducts of Rome, and was written by Sextus Julius Frontinus at the end of the 1st century AD. It is also known as or . It is the earliest official report of an investigation made by a distinguished citizen on Roman engineering works to have survived. Frontinus had been appointed Water Commissioner by the emperor Nerva in AD 96. With the recovery of Frontinus' manuscript from the library at Monte Cassino in 1425, effected by the tireless humanist Poggio Bracciolini, details of the construction and maintenance of the Roman aqueduct system became available once more, just as Renaissance Rome began to revive and require a dependable source of pure water. Water supply of Rome The work presents a history and description of the water-supply of the city of Rome, including the laws relating to its use and maintenance.
