Environmental restrictions meant that the dam had to have a "clean" appearance, so the operational equipment is housed within the dam wall. [ 5 ] [ 18 ] The penstocks are a pair of tunnels, 260 m (850 ft) long and inclined at 56° from the horizontal with a 5.3 m (17 ft) diameter, which then bifurcate into four steel lined 190 m (620 ft) long ...
Arch style dams are commonly made from concrete. To ensure the dam's integrity, a solid contact between the bedrock foundation and the dam's concrete base is required. The dome style dam is a type of arch dam. The dome style dam curves in both the horizontal plane and vertical plane. The arch style dam only curves in the horizontal. [3]
Hydropower is a method of sustainable energy production. Hydropower is now used principally for hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity.
A photo showing an older flashboard system of the Holyoke Dam and the Canal System's original gatehouse. The river between Holyoke and South Hadley contained what was known as the "Great Falls" a natural 53-foot (16 m) drop in the river approximately 86 miles upstream of the Atlantic Ocean.
Mossyrock Dam is a concrete arch-gravity dam on the Cowlitz River near Mossyrock in Lewis County, Washington, United States. The reservoir created by the dam is called Riffe Lake . The primary purpose of the dam is hydroelectric production while flood control is a secondary function. [ 1 ]
Denison Dam, also known as Lake Texoma Dam, is a dam located on the Red River between Texas and Oklahoma that impounds Lake Texoma. The purpose of the dam is flood control, water supply, hydroelectric power production, river regulation, navigation and recreation. [ 3 ]
Made of concrete and steel, the dam is 2,335 m (2,554 yd; 1.451 mi) long and 185 m (607 ft) above sea level at its top. The project used 27.2 million m 3 (35.6 million cu yd) of concrete (mainly for the dam wall), used 463,000 tonnes of steel (enough to build 63 Eiffel Towers ), and moved about 102.6 million m 3 (134.2 million cu yd) of earth ...
At the toe of the dam on its west side is the main hydroelectric power station (Mosul 1). It contains four 187.5 MW (251,400 hp) Francis turbine generators for an installed capacity of 750 MW. Behind the power station are four surge tanks. Downstream of the dam is the Mosul regulation dam, which serves to regulate the tail-waters of the main ...
