Songhua River
The Songhua or Sunghwa River (also Haixi or Xingal, ''Sungari'') is one of the primary rivers of China, and the longest tributary of the Amur. It flows about from Changbai Mountains on the China–North Korea border through China's northeastern Jilin and Heilongjiang provinces. The river drains of land, and has an annual discharge of to . The extreme flatness of the Northeast China Plain has caused the river to meander over time, filling the wide plain with oxbow lakes, as remnants of the previous paths of the river. Geography The Songhua rises south of Heaven Lake, near the China-North Korea border. From there it flows north, to be interrupted by the Baishan, Hongshi and Fengman hydroelectric dams. The Fengman Dam forms a lake that stretches for . Below the dam, the Second Songhua flows north through Jilin, then northwest until it is joined by its largest tributary, the Nen River, near Da'an, to create the Songhua proper. The Songhua turns east through Harbi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Oxbow Lakes
An oxbow lake is a U-shaped lake or stream pool, pool that forms when a wide meander of a river is meander cutoff, cut off, creating a free-standing body of water. The word "oxbow" can also refer to a U-shaped bend in a river or stream, whether or not it is cut off from the main stream. It takes its name from an oxbow which is part of a harness for oxen to pull a plough or cart. In South Texas, oxbows left by the Rio Grande are called ''resaca (channel), resacas''. In Australia, oxbow lakes are called billabongs. Geology An oxbow lake forms when a meandering river erodes through the neck of one of its meanders. This takes place because meanders tend to grow and become more curved over time. The river then follows a shorter course that bypasses the meander. The entrances to the abandoned meander eventually silt up, forming an oxbow lake. Oxbow lakes are stillwater lakes, with no current flowing through them, which causes the lake bed to gradually accumulate silt, becoming a ...

Meander
A meander is one of a series of regular sinuous curves in the Channel (geography), channel of a river or other watercourse. It is produced as a watercourse erosion, erodes the sediments of an outer, concave bank (cut bank, cut bank or river cliff) and deposits sediments on an inner, convex bank which is typically a point bar. The result of this coupled erosion and sedimentation is the formation of a sinuous course as the channel migrates back and forth across the axis of a floodplain. The zone within which a meandering stream periodically shifts its channel is known as a meander belt. It typically ranges from 15 to 18 times the width of the channel. Over time, meanders migrate downstream, sometimes in such a short time as to create civil engineering challenges for local municipalities attempting to maintain stable roads and bridges.Neuendorf, K.K.E., J.P.

History Early history In 1720, Jiamusi was first named Giyamusi (, ) during the Kangxi period by the Nani people, Nanai people. The word Giyamusi originally means "inn" in the Manchu language. Because of the harsh climate and short growing season, the region of modern day Jiamusi was largely uncultivated. Since the Qing government opened Manchuria for farming in order to prevent the conquest of the area by Russia, Jiamusi developed as a small trading post under the name Dongxing () since 1888.

Hydroelectricity
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.

Fengman Dam
The Fengman Dam is a concrete gravity dam from Jilin City on the Second Songhua River in Jilin Province, China. The main purposes of the dam are hydroelectric power generation and flood control. Construction of the dam began in 1937 and was complete in 1953. The dam is owned and operated by Northeast China Grid Company Limited. A new dam was completed in 2019, and the old dam will be dismantled, except for a small section preserved for historical interest . History Construction on the Fengman Dam began in 1937 under the Japanese during their occupation of parts of China during World War II. In November 1942, the reservoir behind the dam began to fill and by March 1943, the first generators were operational. Still lacking floodgates, the dam was not entirely complete after the Japanese occupation in 1953. In 1959, the eighth and final generator of the first stage was installed, bringing the power station's installed capacity to 552.5 MW. Between 1970 and 1979, a tunnel was installe ...
