Alcantarilla Dam
__NOTOC__ The Alcantarilla Dam is a ruined Roman gravity dam in Mazarambroz, Toledo province, Castilla-La Mancha, Spain, dating to the 2nd century BC. The toponym "Alcantarilla" means conduit and is of Arabic origin:It is the diminutive of "alcántara" from the Arabic word ''al-QanTarah'' (القنطرة) meaning "the bridge". the Latin name is unknown. The dam is believed to be the oldest dam in Spain, and is possibly the oldest known Roman dam. It was high and at least long. The dam and reservoir were part of the water supply system of the city of Toletum ( Toledo). They were constructed on a tributary of the River Tagus. The water was conveyed to the city by an aqueduct which passed through Layos. Structure The structure appears to have been similar to the surviving Proserpina Dam near Merida, an earth dam with a stone retaining wall. The upstream retaining wall consists of two parallel rubble-masonry walls about thick, separated by a concrete-filled space approxima ...

Tajo
The Tagus ( ; es, Tajo ; pt, Tejo ; see below) is the longest river in the Iberian Peninsula. The river rises in the Montes Universales near Teruel, in mid-eastern Spain, flows , generally west with two main south-westward sections, to empty into the Atlantic Ocean in Lisbon. Its drainage basin covers – exceeded in the peninsula only by the Douro. The river is highly used. Several dams and diversions supply drinking water to key population centres of central Spain and Portugal; dozens of hydroelectric stations create power. Between dams it follows a very constricted course, but after Almourol, Portugal it has a wide alluvial valley, prone to flooding. Its mouth is a large estuary culminating at the major port, and Portuguese capital, Lisbon. The source is specifically: in political geography, at the Fuente de García in the Frías de Albarracín municipality; in physical geography, within the notably high range, the Sistema Ibérico (Iberian System), of the Sierr ...

Proserpina Dam
The Proserpina Dam is a Roman gravity dam in Mérida, Extremadura, Spain, dating to the 1st or 2nd century AD. It was built as part of the infrastructure which supplied the city of Emerita Augusta with water. After the fall of the Roman Empire, the Milagros aqueduct leading to the city fell into decay, but the earth dam with retaining wall is still in use. Conservation It is also part of the Archaeological Ensemble of Mérida, an UNESCO World Heritage Site since 1993. at UNESCO See also * * |
Gravity Dams
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

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 used in Rome was strongly influenced by Greek and Etruscan sources. Roads Roads were common at that time, but the Romans improved their design and perfected the construction to the extent that many of their roads are still in use today. Their accomplishments surpassed most other civilizations of their time, and after their time, and many of their structures have withstood the test of time to inspire others, especially during the Renaissance. Moreover, their contributions were described in some detail by authors such as Pliny the Elder, so there is a printed record of their many inventions and achievements. Aqueducts A thousand cubic metres (260,000 US gal) of water were brought into Rome by eleven different aqueducts each day. Per c ...

Roman Architecture
Ancient Roman architecture adopted the external language of classical Greek architecture for the purposes of the ancient Romans, but was different from Greek buildings, becoming a new architectural style. The two styles are often considered one body of classical architecture. Roman architecture flourished in the Roman Republic and to even a greater extent under the Empire, when the great majority of surviving buildings were constructed. It used new materials, particularly Roman concrete, and newer technologies such as the arch and the dome to make buildings that were typically strong and well-engineered. Large numbers remain in some form across the former empire, sometimes complete and still in use to this day. Roman architecture covers the period from the establishment of the Roman Republic in 509 BC to about the 4th century AD, after which it becomes reclassified as Late Antique or Byzantine architecture. Few substantial examples survive from before about 100 BC, and most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Bien De Interés Cultural
A Bien de Interés Cultural is a category of the heritage register in Spain. The term is also used in Venezuela and other Spanish-speaking countries. The term literally means a "good of cultural interest" ("goods" in the economic sense) and includes not only material heritage (cultural property), like monuments or movable works of art, but also intangible cultural heritage, such as the Silbo Gomero language. Some ''bienes'' enjoy international protection as World Heritage Sites or Masterpieces of the Oral and Intangible Heritage of Humanity. History In Spain, the category of ''Bien de Interés Cultural'' dates from 1985 when it replaced the former heritage category of '' Monumento nacional ''(national monument) in order to extend protection to a wider range of cultural property. The category has been translated as "Cultural Interest Asset". ''Monumentos'' are now identified as one of the sub-categories of ''Bien de Interés Cultural.'' Sub-categories The movable heritage d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Retaining Wall
Retaining walls are relatively rigid walls used for supporting soil laterally so that it can be retained at different levels on the two sides. Retaining walls are structures designed to restrain soil to a slope that it would not naturally keep to (typically a steep, near-vertical or vertical slope). They are used to bound soils between two different elevations often in areas of terrain possessing undesirable slopes or in areas where the landscape needs to be shaped severely and engineered for more specific purposes like hillside farming or roadway overpasses. A retaining wall that retains soil on the backside and water on the frontside is called a seawall or a bulkhead. Definition A wall for holding in place a mass of earth or the like, as at the edge of a terrace or excavation. A retaining wall is a structure designed and constructed to resist the lateral pressure of soil, when there is a desired change in ground elevation that exceeds the angle of repose of the soil.
