Kurit Dam
The Kurit Dam is a masonry arch dam located 34 km southeast of Tabas, Iran near the village of Kurit. The dam is an early arch dam constructed by the Mongolians around 1350 AD. Dam The dam was originally 60m tall but 4m of height was added in 1850. The dam was constructed in a very narrow gorge and was the tallest in the world up until the early 20th century. The dam also contained a water outlet system considered sophisticated for its time. Currently, the dam does not impound a reservoir and a large segment of its lower downstream face has fallen off. Behind the dam, where the reservoir existed, is now full of silt with the exception of directly behind the upstream face which has been excavated. History Kurit Dam belongs to the post-Islamic historical periods and is located in the village of Kurit, Tabas city, Iran Iran, officially the Islamic Republic of Iran, and also called Persia, is a country located in Western Asia. It is bordered by Iraq and Tur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tabas
Tabas ( fa, طبس, also Romanized as Ṭabas), formerly known as Golshan, is the capital city of Tabas County in South Khorasan Province of Iran. At the 2011 census, its population was 35,150, in 9,903 families. Tabas is located in central Iran, 950 kilometers southeast of Tehran, in South Khorasan Province. At first, it was part of the Khorasan province, but in 2001, it was joined to the Yazd Province. However, in 2013, it was returned to Khorasan, and it became part of South Khorasan province. The name Khorasan means the land of the rising sun. There are two other places in Khorasan called Tabas, but the name Tabas usually refers to the city under discussion. It is a desert city with many date and citrus trees. It has a 300-year-old public garden (Bagh-e-Golshan). There is also a shrine in Tabas that is visited every year by thousands of pilgrims. Tabas has two universities with 2,500 to 3,500 students. The city has hot summers, and people rarely see a winter snowfall. The ...

Outlet Works
A gatehouse, gate house, outlet works or valve house for a dam is a structure housing sluice gates, valves, or pumps (in which case it is more accurately called a pumping station). Many gatehouses are strictly utilitarian, but especially in the nineteenth century, some were very elaborate. Background A set of outlet works is a device used to release and regulate water flow from a dam. Such devices usually consist of one or more pipes or tunnels through the embankment of the dam, directing water usually under high pressure to the river downstream. These structures are usually used when river flow exceeds the capacity of the power plant or diversion capacity of the dam, but do not have flows high enough to warrant the use of the dam spillways. They may also be utilized when river flows must be bypassed due to maintenance work in the power station or diversion gates. Although similar in purpose to spillways, outlet works provide a more controlled release to meet downstream flow requir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dams In South Khorasan Province
A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. The word ''dam'' can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Infrastructure Completed In The 14th Century
Infrastructure is the set of facilities and systems that serve a country, city, or other area, and encompasses the services and facilities necessary for its economy, households and firms to function. Infrastructure is composed of public and private physical structures such as roads, railways, bridges, tunnels, water supply, sewers, electrical grids, and telecommunications (including Internet connectivity and broadband access). In general, infrastructure has been defined as "the physical components of interrelated systems providing commodities and services essential to enable, sustain, or enhance societal living conditions" and maintain the surrounding environment. Especially in light of the massive societal transformations needed to mitigate and adapt to climate change, contemporary infrastructure conversations frequently focus on sustainable development and green infrastructure. Acknowledging this importance, the international community has created policy focused on sustai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures Completed In 1350
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] |
Silt
Silt is granular material of a size between sand and clay and composed mostly of broken grains of quartz. Silt may occur as a soil (often mixed with sand or clay) or as sediment mixed in suspension with water. Silt usually has a floury feel when dry, and lacks plasticity when wet. Silt also can be felt by the tongue as granular when placed on the front teeth (even when mixed with clay particles). Silt is a common material, making up 45% of average modern mud. It is found in many river deltas and as wind-deposited accumulations, particularly in central Asia, north China, and North America. It is produced in both very hot climates (through such processes as collisions of quartz grains in dust storms) and very cold climates (through such processes as glacial grinding of quartz grains.) Loess is soil rich in silt which makes up some of the most fertile agricultural land on Earth. However, silt is very vulnerable to erosion, and it has poor mechanical properties, making construction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum.

Gorge
A canyon (from ; archaic British English spelling: ''cañon''), or gorge, is a deep cleft between escarpments or cliffs resulting from weathering and the erosion, erosive activity of a river over geologic time scales. Rivers have a natural tendency to cut through underlying surfaces, eventually wearing away rock layers as sediments are removed downstream. A river bed will gradually reach a baseline elevation, which is the same elevation as the body of water into which the river drains. The processes of weathering and erosion will form canyons when the river's River source, headwaters and estuary are at significantly different elevations, particularly through regions where softer rock layers are intermingled with harder layers more resistant to weathering. A canyon may also refer to a rift between two mountain peaks, such as those in ranges including the Rocky Mountains, the Alps, the Himalayas or the Andes. Usually, a river or stream carves out such splits between mountains. Examp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mongolian Empire
The Mongol Empire of the 13th and 14th centuries was the largest contiguous land empire in history. Originating in present-day Mongolia in East Asia, the Mongol Empire at its height stretched from the Sea of Japan to parts of Eastern Europe, extending northward into parts of the Arctic; eastward and southward into parts of the Indian subcontinent, attempted invasions of Southeast Asia and conquered the Iranian Plateau; and westward as far as the Levant and the Carpathian Mountains. The Mongol Empire emerged from the unification of several nomadic tribes in the Mongol homeland under the leadership of Temüjin, known by the more famous title of Genghis Khan (–1227), whom a council proclaimed as the ruler of all Mongols in 1206. The empire grew rapidly under his rule and that of his descendants, who sent out invading armies in every direction. The vast transcontinental empire connected the East with the West, and the Pacific to the Mediterranean, in an enforced ''Pax Mongolic ...

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 developme ...
