Du Jiang Yan Irrigation System
The Dujiangyan () is an ancient irrigation system in Dujiangyan City, Sichuan, China. Originally constructed around 256 BC by the State of Qin as an irrigation and flood control project, it is still in use today. The system's infrastructure develops on the Min River (Minjiang), the longest tributary of the Yangtze. The area is in the west part of the Chengdu Plain, between the Sichuan Basin and the Tibetan Plateau. Originally, the Min would rush down from the Min Mountains and slow down abruptly after reaching the Chengdu Plain, filling the watercourse with silt, thus making the nearby areas extremely prone to floods. King Zhao of Qin commissioned the project, and the construction of the Dujiangyan harnessed the river using a new method of channeling and dividing the water rather than simply damming it. The water management scheme is still in use today to irrigate over of land in the region. The Dujiangyan, the Zhengguo Canal in Shaanxi and the Lingqu Canal in Guangxi are coll ...

Dujiangyan City
Dujiangyan () is a county-level city of Sichuan Province, Southwest China, it is under the administration of the prefecture-level city of Chengdu. Its north-west region forms a border with southern Ngawa Tibetan and Qiang Autonomous Prefecture. It has an area of and had a population of 600,000 in 2003. Dujiangyan was formerly a county named Guanxian or Guan County (). The county became a county-level city in 1988 and was renamed after the Dujiangyan Irrigation System, in the city's northwest, famous for providing Chengdu with water for over two millennia, since around 250 BC. History Around 250 BC during the Warring States period, Li Bing, a governor of Shu (present Sichuan Province) in the Qin state with his son directed the construction of Dujiangyan. Li Bing gave up the old ways of dam building, which were simply directed at flood control, employing a new method of channeling and dividing the water of the Min River. He accomplished this by separating the project into tw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Panorama Of Inner Stream Of Dujiangyan Irrigation System
A panorama (formed from Greek πᾶν "all" + ὅραμα "view") is any wide-angle view or representation of a physical space, whether in painting, drawing, photography, film, seismic images, or 3D modeling. The word was originally coined in the 18th century by the English (Irish descent) painter Robert Barker to describe his panoramic paintings of Edinburgh and London. The motion-picture term ''panning'' is derived from ''panorama''. A panoramic view is also purposed for multimedia, cross-scale applications to an outline overview (from a distance) along and across repositories. This so-called "cognitive panorama" is a panoramic view over, and a combination of, cognitive spaces used to capture the larger scale. History The device of the panorama existed in painting, particularly in murals, as early as 20 A.D., in those found in Pompeii, as a means of generating an immersive " panoptic" experience of a vista.

UNESCO 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 ...

Gunpowder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate (saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good propellant but is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bamboo
Bamboos are a diverse group of evergreen perennial flowering plants making up the subfamily Bambusoideae of the grass family Poaceae. Giant bamboos are the largest members of the grass family. The origin of the word "bamboo" is uncertain, but it probably comes from the Dutch or Portuguese language, which originally borrowed it from Malay or Kannada. In bamboo, as in other grasses, the internodal regions of the stem are usually hollow and the vascular bundles in the cross-section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering. Bamboos include some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow within a 24-hour period, at a rate of almost an hour (equivalent to 1 mm every 90 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Levee
A levee (), dike (American English), dyke (Commonwealth English), embankment, floodbank, or stop bank is a structure that is usually earthen and that often runs parallel to the course of a river in its floodplain or along low-lying coastlines. The purpose of a levee is to keep the course of rivers from changing and to protect against flooding of the area adjoining the river or coast. Levees can be naturally occurring ridge structures that form next to the bank of a river, or be an artificially constructed fill or wall that regulates water levels. Ancient civilizations in the Indus Valley, ancient Egypt, Mesopotamia and China all built levees. Today, levees can be found around the world, and failures of levees due to erosion or other causes can be major disasters. Etymology Speakers of American English (notably in the Midwest and Deep South) use the word ''levee'', from the French word (from the feminine past participle of the French verb , 'to raise').

Li Bing (Qin)
Li Bing (; ) was a Chinese hydraulic engineer and politician of the Warring States period. He served the state of Qin as an administrator and is revered for his work on the Dujiangyan River Control System, which both controlled flooding and provided irrigation water year-round, greatly increasing the productivity of the valley. Li Bing became a cultural icon, known as the vanquisher of the River God and is compared to the Great Yu. Dujiangyan is still in use today and is listed as a UNESCO World Heritage Site. Life and career King Zhaoxiang of Qin (r. 306–251 BC) dispatched Li Bing as a joint military and civilian governor (''shou'') over Shu, a recently defeated state in Sichuan province, Southwest China, just west of modern Chengdu. According to the ''Records of the Grand Historian'', Li Bing was appointed governor of Shu in c. 277 BC. However, the ''Chronicles of Huayang'' place Li Bing in Shu in 272 BC. He arrived just as Zhang Ruo had put down the last of the mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
