Guadiana
The Guadiana River (, also , , ), or Odiana, is an international river defining a long stretch of the Portugal-Spain border, separating Extremadura and Andalusia (Spain) from Alentejo and Algarve (Portugal). The river's basin extends from the eastern portion of Extremadura to the southern provinces of the Algarve; the river and its tributaries flow from east to west, then south through Portugal to the border towns of Vila Real de Santo António (Portugal) and Ayamonte (Spain), where it flows into the Gulf of Cádiz. With a course that covers a distance of , it is the fourth-longest in the Iberian peninsula, and its hydrological basin extends over an area of approximately (the majority of which lies within Spain). Etymology The Romans referred to the river as the , the "River of Ducks". During the Moorish occupation and settlement, the name was extended and referred to as ''Wadi Ana'' ('' wādī'' being the Arab term for "river"), later passed on to Portuguese and Spanish ...

Extremadura
Extremadura (; ext, Estremaúra; pt, Estremadura; Fala: ''Extremaúra'') is an autonomous community of Spain. Its capital city is Mérida, and its largest city is Badajoz. Located in the central-western part of the Iberian Peninsula, it is crossed from east to west by the Tagus and Guadiana rivers. The autonomous community is formed by the two largest provinces of Spain: Cáceres and Badajoz. Extremadura is bordered by Portugal to the west and by the autonomous communities of Castile and León (north), Castilla–La Mancha (east) and Andalusia (south). It is an important area for wildlife, particularly with the major reserve at Monfragüe, which was designated a National Park in 2007, and the International Tagus River Natural Park (''Parque Natural Tajo Internacional''). The regional executive body, led by the President of Extremadura, is called Junta de Extremadura. The Day of Extremadura is celebrated on 8 September.

Ancient Rome
In modern historiography, ancient Rome refers to Roman civilisation from the founding of the city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC) and Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually dominated the Italian Peninsula, assimilated the Greek culture of southern Italy (Magna Grecia) and the Etruscan culture and acquired an Empire that took in much of Europe and the lands and peoples surrounding the Mediterranean Sea. It was among the largest empires in the ancient world, with an estimated 50 to 90 million inhabitants, roughly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arch Dam
An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas. Classification In general, arch dams are classified based on the ratio of the base thickness to the structural height (b/h) as: * Thin, for b/h less than 0.2, * Medium-thick, for b/h between 0.2 and 0.3, and * Thick, for b/h ratio over 0.3. Arch dams classified with respect to their structural height are: * Low dams up to , * Medium high dams between , * High dams over . History The develop ...

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 gravi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Arch Dams
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it. Arches may be synonymous with vaults, but a vault may be distinguished as a continuous arch forming a roof. Arches appeared as early as the 2nd millennium BC in Mesopotamian brick architecture, and their systematic use started with the ancient Romans, who were the first to apply the technique to a wide range of structures. Basic concepts An arch is a pure compression form. It can span a large area by resolving forces into compressive stresses, and thereby eliminating tensile stresses. This is sometimes denominated "arch action". As the forces in the arch are transferred to its base, the arch pushes outward at its base, denominated "thrust". As the rise, i. e. height, of the arch decreases the outward thrust increases. In order to preserve arch action and prevent coll ...
