Wusanto Reservoir
Wushantou Reservoir (), sometimes spelled Wushanto or Wusanto, is a reservoir and scenic area located in Lioujia District and Guantian District of Tainan, Taiwan. It is also referred to as Coral Lake () due to its zigzagging shoreline. The reservoir was designed by engineer Yoichi Hatta and was the largest in Asia at the time of its completion in 1930. In 2009 it was listed as a potential World Heritage Site.https://twh.boch.gov.tw/taiwan/index.aspx?lang=en_ushttps://www.moc.gov.tw/en/News_Content2.aspx?n=398&s=14057 Overview Construction of the Wusanto Reservoir began in 1920 and was completed in 1930. The goal of the project was to provide irrigation for over 100-thousand hectares of farmland in the Chianan area. After construction of the reservoir, the irrigation plain became an important producer of rice for consumption in Taiwan and Japan, with three rice harvests possible each year.

Guantian District
Guantian District () is a rural district in central Tainan, Taiwan. It is the hometown of former Taiwanese President Chen Shui-bian. It hosts a population of 20,866 residents. History Guantian (官田) was formerly known as the "Guantian" (官佃). During Dutch rule, this area belonged to the government as "Wang Tian" (王田). During Ming Zheng rule, Wang Tian was changed to "Guantian", and the land was handed over to the civil and military officials, who can then recruit the farmers. Among them, the Chen Yonghua family had the most commitments and gradually formed a Han Chinese settlement, hence the name "Guantian" (官佃). Under the Qing rule, it became "Guantian village" (官佃庄). During the Japanese colonial era in 1920, it was renamed as "Guantian village" (官田庄), belonging to Zengwun County, Tainan Prefecture. In 1953 after the war, it became "Guantian Township" (官田鄉).

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. \mathrm. In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the vo ...

Asia
Asia ( , ) is the largest continent in the world by both land area and population. It covers an area of more than 44 million square kilometres, about 30% of Earth's total land area and 8% of Earth's total surface area. The continent, which has long been home to the majority of the human population, was the site of many of the first civilisations. Its 4.7 billion people constitute roughly 60% of the world's population. Asia shares the landmass of Eurasia with Europe, and of Afro-Eurasia with both Europe and Africa. In general terms, it is bounded on the east by the Pacific Ocean, on the south by the Indian Ocean, and on the north by the Arctic Ocean. The border of Asia with Europe is a social constructionism, historical and cultural construct, as there is no clear physical and geographical separation between them. A commonly accepted division places Asia to the east of the Suez Canal separating it from Africa; and to the east of the Turkish straits, the Ural Mountains an ...

Chianan Irrigation
Chianan Irrigation (), also known as the Kanan Irrigation System, was built to support agricultural production in the Chianan Plain of Taiwan. The name "chia-nan" was derived from two place names among its surrounding area called Chiayi and Tainan. Although it includes some other facilities, such as the Wusanto Reservoir, the term "Chianan Canal", in a narrow sense, would only mean the canals of this system. The main designer of the Chianan Canal is Yoichi Hatta, a civil engineer of the Japanese government. Its main streams pass through today's Tainan, Chiayi and Yunlin, formerly parts of Tainan Prefecture. The architectural work of canal was launched in 1920 and completed in 1930, during Japanese rule. The canal improved the plantable area for rice from 5000 to 150,000 hectare The hectare (; SI symbol: ha) is a non-SI metric unit of area equal to a square with 100-metre sides (1 hm2), that is, square metres (), and is primarily used in the measurement of lan ...

Wushantou Dam
Wushantou Dam () is an embankment dam in Guantian District, Tainan, Taiwan. The dam was designed by Yoichi Hatta and built between 1920 and 1930 during Japanese rule to provide irrigation water for the Chianan Plain as part of the Chianan Irrigation system. Because the natural flow of the Guantian River and other local streams was insufficient for irrigation of a planned , a tunnel was constructed to divert water from the Zengwen River to fill the reservoir. In 1974, the Zengwen Dam was completed on the Zengwen River shortly above the diversion tunnel, stabilizing and reducing the sediment load of water flowing into Wushantou Reservoir. The dam consists of a curved embankment high and long, containing of material. The reservoir comprises and was designed to store of water. However, as of 1990 it had been reduced to due to severe erosion problems upstream. A concrete overflow spillway is located shortly to the south of the dam, providing a maximum outflow of . The dam sits ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydraulic Fill
Hydraulic fill is a means of selectively emplacing soil or other materials using a stream of water. It is also a term used to describe the materials thus emplaced. Gravity, coupled with velocity control, is used to effect the selected deposition of the material. Borrow pits containing suitable material are accessible at an elevation such that the earth can be sluiced to the fill after being washed from the bank by high-pressure nozzles. Hydraulic fill is likely to be the most economic method of construction. Even when the source material lacks sufficient elevation, it can be elevated to the sluice by a dredge pump. In the construction of a hydraulic fill dam, the edges of the dam are defined by low embankments or dykes which are built upward as the fill progresses. The sluices are carried parallel to, and just inside of, these dykes. The sluices discharge their water-earth mixture at intervals, the water fanning out and flowing towards the central pool which is maintained a ...

Earthquake
An earthquakealso called a quake, tremor, or tembloris the shaking of the Earth's surface resulting from a sudden release of energy in the lithosphere that creates seismic waves. Earthquakes can range in intensity, from those so weak they cannot be felt, to those violent enough to propel objects and people into the air, damage critical infrastructure, and wreak destruction across entire cities. The seismic activity of an area is the frequency, type, and size of earthquakes experienced over a particular time. The seismicity at a particular location in the Earth is the average rate of seismic energy release per unit volume. In its most general sense, the word ''earthquake'' is used to describe any seismic event that generates seismic waves. Earthquakes can occur naturally or be induced by human activities, such as mining, fracking, and nuclear weapons testing. The initial point of rupture is called the hypocenter or focus, while the ground level directly above it is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
