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 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 Sepulveda Dam is a project of the U.S. Army Corps of Engineers designed to withhold winter flood waters along the Los Angeles River. Completed in 1941, at a cost of $6,650,561, it is located south of center in the San Fernando Valley, approximately eight miles east of the river's source in the western end of the Valley, in Los Angeles, California.
The Shinano River, known as the Chikuma River in its upper reaches, is the longest and widest river in Japan and the third largest by basin area. It is located in northeastern Honshu, rising in the Japanese Alps and flowing generally northeast through Nagano and Niigata Prefectures before emptying into the Sea of Japan.
The Kuma River is a river in Kumamoto Prefecture, central Western part of Kyūshū, Japan. It is sometimes referred as Kumagawa River. It is the longest river in Kyushu, with the length of 115 km long and has a drainage area of 1,880 km2 (730 sq mi). The tidal flat of the Kuma River estuary is approximately 1000 hectares.
Malampuzha Dam is the second largest dam and reservoirs in Kerala, located near Palakkad, in the state of Kerala in South India, built post independence by the then Madras state. Situated in the scenic hills of the Western Ghats in the background it is a combination of a masonry dam with a length of 1,849 metres and an earthen dam with a length of 220 metres making it the longest dam in the state. The dam is 355 feet high and crosses the Malampuzha River, a tributary of Bharathappuzha, Kerala's second longest river. There is a network of two canal systems that serve the dam's reservoir of 42,090 hectares.
Shiwaguchi Station is a JR West Geibi Line station located in Ibara, Shiraki-chō, Asakita-ku, Hiroshima, Hiroshima Prefecture, Japan. The "Shiwa" in the name derives from the nearby Shiwa-chō, Higashihiroshima, despite there being no shuttle bus or other connection between the two locations. This station should not be confused with other stations of similar-sounding name on the Geibi Line: Shimowachi, Shiomachi, and Shiwachi. Even though Shiwaguchi Station is an express stop station, the Miyoshi Liner does not stop here due to lack of passengers using the station.
The Concordia Association was a political party in Manchukuo. Established to promote the ideals of Pan-Asianism and the creation of a multi-ethnic nation-state and to create a structure which would gradually replace military rule over Manchukuo with civilian control, the party was unable to fulfill its promise, and was eventually subverted into an instrument of totalitarian state-control by the Japanese Kwantung Army.
Shiraki Station is a passenger railway station in located in the city of Toba, Mie Prefecture, Japan, operated by the private railway operator Kintetsu Railway.
The Shō River has its source in Mount Eboshi in the Shōkawa-chō area of Takayama, Gifu Prefecture, Japan. After flowing for 115 km (71 mi) through the northern part of Gifu Prefecture and the western part of Toyama Prefecture, it empties into Toyama Bay.
Xylota is a Holarctic genus of hoverflies similar in structure to the related genera Chalcosyrphus and Brachypalpoides. As the larvae are saprophytic they're usually found in rotting wood. The adult flies are generally associated with woodland and woodland edges and can often be seen running over the upper sides of leaves. Unlike other syrphids the adults of many species rarely visit flowers preferring instead to gather pollen from leaf surfaces. There are over 100 described species of which 12 can be found in Europe. Seven species have been recorded in Britain.
The Samanala Dam is a dam primarily used for hydroelectric power generation in Sri Lanka. Commissioned in 1992, the Samanalawewa Project is the third-largest hydroelectric scheme in the country, producing 405 GWh of energy annually. It was built with financial support from Japan and the United Kingdom. It is notable for a large leak on its right bank. Power production continues as planned despite the leakage, and the water from the leak now provides two thirds of the water issued by the reservoir for agriculture in downstream areas.
Blera is a genus of hoverflies. It is primarily a North American genus, though there are 3 species from Europe. external map
Sphegina is a genus of small, slender hoverflies. They are widespread throughout Eurasia and North America. In flight they seem to have long hind legs which they often carry hanging down, making them resemble sphecid or ichneumonid wasps. Adult Sphegina are usually found in damp and shady habitats close to water in forested areas, and several species can often be found together. They often feed on white and yellow flowers of Apiaceae, Ranunculaceae, Asteraceae, and Rosaceae like Crataegus, Sorbus, and Sorbaria. Larvae nest in the sap of living and dead trees or in decaying cambium under tree bark lying in water or other damp conditions. The larvae of some species have been discovered in the tunnels of other xylophagous insects.
The Gōnokawa River is a river that runs through Hiroshima and Shimane prefectures in Japan. It is the largest river in the Chūgoku region. It is also called the Gōgawa River and, in Hiroshima, the Enokawa River.
Water supply and sanitation in Japan is characterized by numerous achievements and some challenges. The country has achieved universal access to water supply and sanitation; has one of the lowest levels of water distribution losses in the world; regularly exceeds its own strict standards for the quality of drinking water and treated waste water; uses an effective national system of performance benchmarking for water and sanitation utilities; makes extensive use of both advanced and appropriate technologies such as the jōkasō on-site sanitation system; and has pioneered the payment for ecosystem services before the term was even coined internationally. Some of the challenges are a decreasing population, declining investment, fiscal constraints, ageing facilities, an ageing workforce, a fragmentation of service provision among thousands of municipal utilities, and the vulnerability of parts of the country to droughts that are expected to become more frequent due to climate change.
The Shin-Takasegawa Pumped Storage Station (新高瀬川発電所) uses the Takase River to operate a pumped storage hydroelectric scheme about 12 kilometres (7.5 mi) west of Ōmachi in Nagano Prefecture, Japan. Part of the system is within Chūbu-Sangaku National Park.
The Okutadami Dam (奥只見ダム) is a concrete gravity dam on the Tadami River, 26 km (16 mi) east of Uonuma on the border of Niigata and Fukushima Prefectures, Japan. The primary purpose of the dam is hydroelectric power generation and it supports a 560 MW power station which is the largest conventional hydroelectric power station in Japan. The dam also forms the second largest reservoir in Japan, next to that of the Tokuyama Dam.
Family 2 is a 2001 Japanese yakuza film directed by Takashi Miike, released on home video as the sequel to his earlier film Family.
Odontotermes formosanus is a species of fungus-growing termite in the family Termitidae. It is native to southeastern Asia and was first described from Taiwan. This termite cultivates a symbiotic fungus in a special chamber in the nest. Workers and soldiers gather vegetable detritus which they bring back to the colony, chewing the material to a pulp to make a suitable substrate on which to grow the fungus.
