Ōi Dam
The is a dam located between the cities of Ena and Nakatsugawa in Gifu Prefecture, Japan. It was built to produce electricity for the surrounding area. The Agi River flows through the dam. Built in 1924, the Ōi Dam was the first dam built anywhere on the Kiso River system. It is also the first full-scale hydroelectric dam built in Japan. At tall, it is the largest gravity dam in Japan after the Taishakugawa Dam in Hiroshima Prefecture. In 1983, the New Ōi Dam (新大井ダム ''Shin-Ōi Damu'') was built just downstream. Combined, they produce 80,000 kW of power. History The upper portions of the Kiso River have a strong flow in terms of speed and volume, making it an ideal location for hydroelectric dams. Interest in hydroelectric dams in Japan grew greatly in 1911 when a hydroelectric law was passed. Given the technologies of the time, though, building a dam along the Kiso River was too difficult because floods often occurred. The introduction of hydroelectric po ...

Gravity Dam
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. 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. Stability of the dam primarily arises from the range of normal force angles viably generated by the foundation. Also, the stiff nature of a gravity dam structure endures differential foundation settlement poorly, as it can crack the dam structure. The main advantage to gravity dams over embankments is the scour-resistance of concrete, which protects against damage from minor over-topping flows. Unexpected large over-topping flows are still a problem, as they can scour dam foundations. A disadvantage of gra ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Maruyama Dam
The is a dam on the border of Mitake and Yaotsu in Gifu Prefecture, Japan. It was built on the upper reaches of the Kiso River system. It is a gravity dam that is tall. It is the site of a power plant. It was built after World War II as part of a large, nationwide dam building project. Surrounding area Sosui Gorge (蘇水峡 ''Sosui-kyō'') was formed by the completion of the dam. Along with Ena Gorge further upstream, the area is part of the Hida-Kisogawa Quasi-National Park is a quasi-national park in Japan.

Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley and rely on the natural topography to provide most of the basin of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Momosuke Fukuzawa
Momosuke Fukuzawa (福澤 桃介 ''Fukuzawa Momosuke'', June 25, 1868 – February 2, 1938) was a Japanese businessman nicknamed "The Wizard of the Money Markets" for his financial success and "The King of Electrical Power" for being the first Japanese to introduce hydroelectric power to the country. He formulated his ideology of 'ikkasen hitokaisha' (one river for one company). Early life Momosuke Iwasaki was born in a small village near Kawagoe “where his family had been village elders and prosperous farmers for three hundred years.” His father Kiichi was the second son so he only inherited a few paddy fields. “Kiichi was a rather impractical, scholarly type, who much preferred sitting at home with his brush, perfecting his calligraphy, to breaking his back in the fields.” To support the family his mother Sada opened a shop but they “were frequently on the verge of bankruptcy.” As Momosuke was finishing school, a neighbor, “a lower-ranking keeper of the town o ...

Hydroelectric Dam
Hydroelectricity, or hydroelectric power, is Electricity generation, electricity generated from hydropower (water power). Hydropower supplies 15% of the world's electricity, almost 4,210 TWh in 2023, which is more than all other Renewable energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Ena Gorge
is a river valley located at the mid reaches of the Kiso River, which runs through the cities of Ena and Nakatsugawa in Gifu Prefecture, Japan. Ena Gorge was so named by Shiga Shigetaka, a geographer of that time who praised the harmony of the mysteriously shaped rocks, which appeared to be continuous with the lakeside vista of Ōi Dam. It is situated in Ena Gorge Prefectural Park. The mysteriously shaped rock formations are prominent throughout. Byobu Rock, Gunkan Rock, Shishi Rock, Kagami Rock, and more can be seen, and there are jet boats that afford passengers a closer look at the rocks. This is also a very important place geologically. There is a Mineral Museum. The area also thrives as a vacation spot with close proximity to the Nagoya Metropolitan area. Ena-kyo Ohashi Bridge spans Ena Gorge.

Kiso River
The is a river in the Chubu region of Japan roughly long, flowing through the prefectures of Nagano, Gifu, Aichi, and Mie before emptying into Ise Bay a short distance away from the city of Nagoya.Nussbaum, Louis Frédéric ''et al.'' (2005). "Kiso-gawa" in ; n.b., Louis-Frédéric is pseudonym of Louis-Frédéric Nussbaum, seDeutsche Nationalbibliothek Authority File. It is the main river among the Kiso Three Rivers (along with the Ibi and Nagara rivers) and forms a major part of the Nōbi Plain. The valley around the upper portion of the river forms the Kiso Valley. Parts of the Kiso River are sometimes referred to as the Japan Rhine because of its similarities to the Rhine in Europe. Kiso River embankment The was built in the Edo period and extends for a 47 kilometer between the cities of Inuyama and Yatomi to protect against flooding. After a portion of this embankment was rebuilt following collapse due to record floods in May 1884, local volunteers brought in ...
