Narude Dam
The Narude Dam is a gravity dam on the Shō River about south of Nanto on the border of Toyama and Gifu Prefectures, Japan. It was constructed between 1950 and 1952. The dam has an associated 97 MW hydroelectric 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 energ ... power station which was built in two parts. The first part of the power station (37 MW) was commissioned in 1951 and the second part of the power station (60 MW) was commissioned in 1975. Of the nine dams on the Shō River it is the sixth furthest downstream.

Toyama Prefecture
is a prefecture of Japan located in the Chūbu region of Honshu. Toyama Prefecture has a population of 993,848 (1 January 2025) and has a geographic area of 4,247.61 km2 (1,640.01 sq mi). Toyama Prefecture borders Ishikawa Prefecture to the west, Gifu Prefecture to the south, Nagano Prefecture to the east, and Niigata Prefecture to the northeast. Toyama is the capital and largest city of Toyama Prefecture, with other major cities including Takaoka, Imizu, and Nanto. Toyama Prefecture is part of the historic Hokuriku region, and the majority of the prefecture's population lives on Toyama Bay, one of the largest bays in Japan. Toyama Prefecture is the leading industrial prefecture on the Japan Sea coast and has the advantage of cheap electricity from abundant hydroelectric resources. Toyama Prefecture contains the only known glaciers in East Asia outside of Russia, first recognized in 2012, and 30% of the prefecture's area is designated as national parks. History ...

Hydroelectric
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.

Dams Completed In 1952
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 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. Ancient dams were built in Mesopotamia and the Middle East for water control. The earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. Egyptians also built dam ...

Gravity Dams
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 gravi ...
