Roman Dam Of Pego Da Moura
The Roman Dam of Pego da Moura is a small buttress dam situated in the municipality of Grândola in the Setúbal District of Portugal. Description The dam was constructed during the middle of the Roman occupation of Portugal. Built in two phases, it consists of a rectilinear wall that was originally about 40 metres long. The ruins have a maximum height of 3 m. and a thickness of 2.90 m. There are six downstream buttresses that are 2.50 m. apart, which are around 2.70 m. thick and 2.90 m long. There is also a semi-circular well, built in masonry, which probably comes from a later period. The dam was almost entirely constructed using ''opus incertum''. In the middle there is a vaulted chamber for which ''opus signinum'' was used. Traces of a water mill can be identified. The dam is located on a small stream and has an approximate watershed of just 2.3 km2. The area of water that could be dammed was around 0.12 km2. The small size means that researchers have concluded that the dam ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Portugal
Portugal, officially the Portuguese Republic ( pt, República Portuguesa, links=yes ), is a country whose mainland is located on the Iberian Peninsula of Southwestern Europe, and whose territory also includes the Atlantic archipelagos of the Azores and Madeira. It features the westernmost point in continental Europe, and its Iberian portion is bordered to the west and south by the Atlantic Ocean and to the north and east by Spain, the sole country to have a land border with Portugal. Its two archipelagos form two autonomous regions with their own regional governments. Lisbon is the capital and largest city by population. Portugal is the oldest continuously existing nation state on the Iberian Peninsula and one of the oldest in Europe, its territory having been continuously settled, invaded and fought over since prehistoric times. It was inhabited by pre-Celtic and Celtic peoples who had contact with Phoenicians and Ancient Greek traders, it was ruled by the Ro ...

Buttress Dam
A buttress dam or hollow dam is a dam with a solid, water-tight upstream side that is supported at intervals on the downstream side by a series of buttresses or supports. The dam wall may be straight or curved. Most buttress dams are made of reinforced concrete and are heavy, pushing the dam into the ground. Water pushes against the dam, but the buttresses are inflexible and prevent the dam from falling over. Buttress or hollow gravity dams were originally built to retain water for irrigation or mining in areas of scarce or expensive resources but cheap labour. A buttress dam is a good choice in wide valleys where solid rock is rare. As designs have become more sophisticated, the virtues and weaknesses of buttress dams have become apparent. The Romans were the first to use buttresses to increase the stability of a dam wall. Buttress dams of slab concrete construction became popular in the United States in the early 20th Century with the patented process of Norwegian-American civil ...

Lusitania
Lusitania (; ) was an ancient Iberian Roman province located where modern Portugal (south of the Douro river) and a portion of western Spain (the present Extremadura and the province of Salamanca) lie. It was named after the Lusitani or Lusitanians, Lusitanian people (an Proto-Indo-Europeans, Indo-European people). Its capital was ''Emerita Augusta'' (currently Mérida, Spain), and it was initially part of the Roman Republic province of Hispania Ulterior, before becoming a province of its own in the Roman Empire. Romans first came to the territory around the mid-2nd century BC. A Lusitanian War, war with Lusitanian tribes followed, from 155 to 139 BC. In 27 BC, the province was created. Lusitania was and is often used as an alternative name for Portugal. Origin of the name The etymology of the name of the Lusitanians, Lusitani (who gave the Roman province its name) remains unclear. Popular etymology connected the name to a supposed Roman demigod Lusus, whereas some early-mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buttress
A buttress is an architectural structure built against or projecting from a wall which serves to support or reinforce the wall. Buttresses are fairly common on more ancient buildings, as a means of providing support to act against the lateral (sideways) forces arising out of inadequately braced roof structures. The term ''counterfort'' can be synonymous with buttress and is often used when referring to dams, retaining walls and other structures holding back earth. Early examples of buttresses are found on the Eanna Temple (ancient Uruk), dating to as early as the 4th millennium BC. Terminology In addition to flying and ordinary buttresses, brick and masonry buttresses that support wall corners can be classified according to their ground plan. A clasping or clamped buttress has an L shaped ground plan surrounding the corner, an angled buttress has two buttresses meeting at the corner, a setback buttress is similar to an angled buttress but the buttresses are set back from the ...

Opus Signinum
''Opus signinum'' ('cocciopesto' in modern Italian) is a building material used in ancient Rome. It is made of tiles broken up into very small pieces, mixed with mortar, and then beaten down with a rammer. Pliny the Elder in his '' Natural History'' describes its manufacture: "Even broken pottery has been utilized; it being found that, beaten to powder, and tempered with lime, it becomes more solid and durable than other substances of a similar nature; forming the cement known as the "Signine" composition, so extensively employed for even making the pavements of houses." Pliny's use of the term "signine" references "Signia (modern Segni), the name of a town in Latium which was famous for its tiles." Origins, spread, disuse The technique, most probably invented by the Phoenicians, is documented in the early 7th cent. BC at Tell el-Burak (Lebanon), then in Phoenician colonies in North Africa, some time before 256 BC, and spread north from there to Sicily and finally to the Italian ...

List Of Roman Dams And Reservoirs
This is a list of Roman dams and reservoirs. The study of Roman dam-building has received little scholarly attention in comparison to their other civil engineering activities, even though their contributions in this field have been ranked alongside their expertise in constructing the well-known Roman aqueducts, bridges, and roads. Roman dam construction began in earnest in the early imperial period. For the most part, it concentrated on the semi-arid fringe of the empire, namely the provinces of North Africa, the Near East, and Hispania. The relative abundance of Spanish dams below is due partly to more intensive field work there; for Italy only the Subiaco Dams, created by emperor Nero (54–68 AD) for recreational purposes, are attested. These dams are noteworthy, though, for their extraordinary height, which remained unsurpassed anywhere in the world until the Late Middle Ages. The most frequent dam types were earth- or rock-filled embankment dams and masonry gravity d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Muro Dam
The Muro Dam was a Roman dam in Portugal. Located near the eastern municipality of Campo Maior, it is the largest surviving ancient dam in the country south of the Tagus river. The 174 m long structure features three slight bends in its course. Its downstream side is supported by a series of thirteen small buttresses at intervals of 3–4 m. The central section, where the dam is highest and strongest, is further strengthened on its air-side by three vertical arches which go from buttress to buttress. See also *List of Roman dams and reservoirs *Roman architecture *Roman engineering The ancient Romans were famous for their advanced engineering accomplishments. Technology for bringing running water into cities was developed in the east, but transformed by the Romans into a technology inconceivable in Greece. The architecture ...

Archaeological Sites In Setúbal District
Archaeology or archeology is the scientific study of human activity through the recovery and analysis of material culture. The archaeological record consists of artifacts, architecture, biofacts or ecofacts, sites, and cultural landscapes. Archaeology can be considered both a social science and a branch of the humanities. It is usually considered an independent academic discipline, but may also be classified as part of anthropology (in North America – the four-field approach), history or geography. Archaeologists study human prehistory and history, from the development of the first stone tools at Lomekwi in East Africa 3.3 million years ago up until recent decades. Archaeology is distinct from palaeontology, which is the study of fossil remains. Archaeology is particularly important for learning about prehistoric societies, for which, by definition, there are no written records. Prehistory includes over 99% of the human past, from the Paleolithic until the advent o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
