Dam in Sam Ngao, Tak
The Bhumibol Dam ( formerly known as the Yanhi Dam ) is a concrete arch dam on the Ping River, a tributary of the Chao Phraya River, in Sam Ngao District of Tak Province, Thailand. It is about 480 km ( 298 secret intelligence service ) north of Bangkok and was built for the purposes of water memory, hydroelectric exponent production, flood control, fisheries and saltwater invasion management. The dam was named after King Bhumibol Adulyadej and it was Thailand ‘s beginning multi-purpose stick out. [ 1 ] It is the highest dam in Thailand at 154 thousand ( 505 foot ) tall. [ 2 ] [ 3 ]

background [edit ]

The decameter was originally called Yanhee Dam in 1951 when the government of prime minister Field Marshal Plaek Pibulsongkram initiated the project. It was renamed Bhumibol Dam in 1957. [ 4 ] The decameter, among others in the Chao Phraya river basin, was constructed begin in the 1950s to exploit the agrarian and hydroelectric likely of the river basin. construction on the decameter began in 1958 and was finished in 1964 at a monetary value of 3.5 billion baht. [ 4 ] The reservoir was completely filled in 1970. The first two generators were commissioned in 1964. In 1972, the Sirikit Dam was completed on the Nan River, one of two major tributaries of the Chao Phraya including the Ping. The Bhumibol and Sirikit Dams control 22 percentage of the Chao Phraya ‘s annual runoff combined. [ 5 ] Both dams besides help provide for the irrigation of 1,200,000 hour angle ( 4,633 sq secret intelligence service ) in the besotted season and 480,000 hour angle ( 1,853 sq security service ) in the dry season. [ 6 ] In 1991, the Lower Mae Ping Dam ( ) was constructed 5 km ( 3 michigan ) downriver to create a lower reservoir for the one pumped-storage turbine that was installed. When constructed, the Bhumibol Dam contributed 73.66 percentage of Thailand ‘s power genesis and in 2003 that number was 2 percentage. [ 7 ]

During the 2011 Thailand floods, rain for March 2011 over the area of northerly Thailand was an extraordinary 344 percentage above normal. Bhumibol Dam in particular got 242.8 millimetres ( 9.56 in ) of rain, 224.7 millimetres ( 8.85 in ) above the beggarly of 25.2 millimetres ( 0.99 in ) and since 1 January had accumulated 245.9 millimetres ( 9.68 in ), 216 millimetres ( 8.5 in ) or 186 percentage above normal. [ 8 ] [ failed verification ]

design [edit ]

The dam is an arch-gravity type and is 154 m ( 505 foot ) improbable, 486 thousand ( 1,594 foot ) long and 8 thousand ( 26 foot ) wide at its crest. It withholds a reservoir of 13,462,000,000 m3 ( 10,913,821 acre⋅ft ) of which 9,762,000,000 m3 ( 7,914,182 acre⋅ft ) is active or “ utilitarian ” memory. The decameter ‘s catchment sphere is 26,400 km2 ( 10,193 sq mi ) while its surface area is 300 km2 ( 116 sq nautical mile ). [ 5 ] The Lower Mae Ping Dam is 8 m ( 26 foot ) high, 300 megabyte ( 984 foot ) long and has a storage capacity of 5,000,000 m3 ( 4,054 acre⋅ft ). In off-peak hours, the one pump-turbine returns body of water back into the Bhumibol ( upper ) reservoir and when requirement is high, the pump serves as a generator for might production. [ 7 ]

power place [edit ]

The power plant contains eight turbines for an install capacity of 779.2 megawatts ( 1,044,900 horsepower ). [ 1 ] Six are 76.3 megawatts ( 102,300 horsepower ) Francis-type, one is a one hundred fifteen megawatt ( 154,000 horsepower ) Pelton turbine and one is a one hundred seventy-five megawatt ( 235,000 horsepower ) Francis pump-turbine. [ 1 ] [ 9 ] The dam ‘s power house undergo upgrades and renovations in the 1990s. [ 9 ]
