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 * * |
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 settle ...

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 ...

Buildings And Structures In The Province Of Badajoz
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artistic ... [...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 ...

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] |
World Heritage Site
A World Heritage Site is a landmark or area with legal protection by an international convention administered by the United Nations Educational, Scientific and Cultural Organization (UNESCO). World Heritage Sites are designated by UNESCO for having cultural, historical, scientific or other form of significance. The sites are judged to contain " cultural and natural heritage around the world considered to be of outstanding value to humanity". To be selected, a World Heritage Site must be a somehow unique landmark which is geographically and historically identifiable and has special cultural or physical significance. For example, World Heritage Sites might be ancient ruins or historical structures, buildings, cities, deserts, forests, islands, lakes, monuments, mountains, or wilderness areas. A World Heritage Site may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet, or it might be a place of great natural beauty. A ...

Earth Dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance. Types Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam. The core can be of clay, concrete, or asphalt concrete. This type of dam is a good choice for sites with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mérida, Spain
Mérida () is a city and municipality of Spain, part of the Province of Badajoz, and capital of the autonomous community of Extremadura. Located in the western-central part of the Iberian Peninsula at 217 metres above sea level, the city is crossed by the Guadiana and Albarregas rivers. The population was 60,119 in 2017. '' Emerita Augusta'' was founded as a Roman colony in 25 BC under the order of the emperor Augustus to serve as a retreat for the veteran soldiers (emeritus) of the legions V Alaudae and X Gemina. The city, one of the most important in Roman Hispania, was endowed with all the comforts of a large Roman city and served as capital of the Roman province of Lusitania since its founding and as the capital of the entire Diocese of Hispania during the fourth century. Following invasions from the Visigoths, Mérida remained an important city of the Visigothic Kingdom of Hispania in the 6th century. In the 713, the city was conquered by the Umayyad Caliphate, and remained ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
