Tipaimukh Dam
Tipaimukh Dam is a proposed embankment dam on the river Surma-Meghna River System, Barak in Manipur state India, first commissioned in 1983. The purpose of the dam is flood control and hydroelectric power generation. It has been subject to repeated delays as the project developed, as there has been controversy between India and Bangladesh over water rights, in addition to questions of environmental effects of the huge project, as well as the need to relocate indigenous Hmar people to make way for a vast reservoir. In 2013, the governments of India and Bangladesh announced further delays, as the latter nation undertakes additional studies about expected effects and mitigating measures. Technical features The dam is planned to be 390m long and 162.8m high, across the Barak River, which enters Bangladesh below the proposed dam location. The dam's crest elevation will be at an altitude of about 180 m. above mean sea level, with a maximum reservoir level of 178 m. The dam was originall ...

Barak River
The Barak River flows through the states of Manipur, Nagaland, Mizoram and Assam in India. Further it enters Bangladesh where it bifurcates into the Surma river and the Kushiyara river which converges again to become the Meghna river before forming the Ganges Delta with the Ganga and the Brahmaputra rivers and flowing into the Bay of Bengal. Of its length is in India, on the Indo–Bangladesh border and the rest is in Bangladesh. The upper part of its navigable part is in India — between Lakhipur and Bhanga, declared as National Waterway 6, (NW-6) since the year 2016. It drains a basin of , of which lies in India, 1.38% (rounded) of the country. The water and banks host or are visited by a wide variety of flora and fauna. The principal tributaries are all in India: the Sonai (or Tuirial), the Jiri, the Tlawng (or Dhaleswari, or Katakal), the Jatinga, the Longai and the Madhura. Tipaimukh Dam is a proposed dam on the river itself. Sources From its source at Liya ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the International System of Units, International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantification (science), quantify the rate of Energy transformation, energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish people, Scottish invention, inventor, mechanical engineer, and chemist who improved the Newcomen steam engine, Newcomen engine with his own Watt steam engine, steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one Newton (unit), newton, the rate at which Work (physics), work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potentia ...

Francis Turbine
The Francis turbine is a type of water turbine. It is an inward-flow reaction turbine that combines radial and axial flow concepts. Francis turbines are the most common water turbine in use today, and can achieve over 95% efficiency. The process of arriving at the modern Francis runner design took from 1848 to approximately 1920. It became known as the Francis turbine around 1920, being named after British-American engineer James B. Francis who in 1848 created a new turbine design. Francis turbines are primarily used for producing electricity. The power output of the electric generators generally ranges from just a few kilowatts up to 1000 MW, though mini-hydro installations may be lower. The best performance is seen when the head height is between . Penstock diameters are between . The speeds of different turbine units range from 70 to 1000 rpm. A wicket gate around the outside of the turbine's rotating runner controls the rate of water flow through the turbine for d ...

Embankment Dam
An embankment dam is a large artificial dam. It is typically created by the placement and compaction of a complex semi-plastic mound of various compositions of soil or rock. It has a semi-pervious waterproof natural covering for its surface and a dense, impervious core. This makes the dam impervious to surface or seepage erosion. Such a dam is composed of fragmented independent material particles. The friction and interaction of particles binds the particles together into a stable mass rather than by the use of a cementing substance. Types Embankment dams come in two types: the earth-filled dam (also called an earthen dam or terrain dam) made of compacted earth, and the rock-filled dam. A cross-section of an embankment dam shows a shape like a bank, or hill. Most have a central section or core composed of an impermeable material to stop water from seeping through the dam. The core can be of clay, concrete, or asphalt concrete. This type of dam is a good choice for sites wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Surma-Meghna River System
The Surma-Meghna River System is a river complex in the Indian Subcontinent, one of the three that form the Ganges Delta, the largest on earth. It rises in the Manipur Hills of northeast India as the Barak River and flows west becoming the Surma River and then flows south as the Meghna River, a total of of which are within Bangladesh, to the Bay of Bengal. Course Barak From its source in the Manipur Hills of India, Liyai Village of Poumai tribe, the river is known as the Barak River (locally known as Avoure). Near its source, the river receives a number of tributaries, including the Irang, Makru, Tuivai, Jiri, Gumti, Howrah, Kagni, Senai Buri, Hari Mangal, Kakrai, Kurulia, Balujhuri, Shonaichhari and Durduria. It flows south through Manipur State, then southwest leaving Manipur and entering Assam State at Tipaimukh or Ruonglevaisuo after abruptly veering north a it's confluence with the Tuivai. In Assam the State Barak flows northward then west receiving many small tribut ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manipur
Manipur () ( mni, Kangleipak) is a state in Northeast India, with the city of Imphal as its capital. It is bounded by the Indian states of Nagaland to the north, Mizoram to the south and Assam to the west. It also borders two regions of Myanmar, Sagaing Region to the east and Chin State to the south. The state covers an area of . Manipur has been at the crossroads of Asian economic and cultural exchange for more than 2,500 years. It connects the Indian subcontinent and Central Asia to Southeast Asia, East Asia, Siberia, regions in the Arctic, Micronesia and Polynesia enabling migration of people, cultures and religions. During the days of the British Indian Empire, the Kingdom of Manipur was one of the princely states. Between 1917 and 1939, some people of Manipur pressed the princely rulers for democracy. By the late 1930s, the princely state of Manipur negotiated with the British administration its preference to continue to be part of the Indian Empire, rather than part of B ...

Hmar People
Hmar, also spelled as Mar, are one of the ethnic peoples of the Chin-Kuki-Mizo living in Northeast Indian state of Manipur and Mizoram, western Myanmar (Burma) and eastern Bangladesh. Population Manipur In the 2011 census, there were 49,081 Hmars in Manipur. Mizoram The exact population of the Hmars in Mizoram is not known. In the first census of 1901 there were 10,411 Hmar language speakers. By 1961 the population was assessed to be 3,118, and then 4,524 in 1971. In the 2001 census, 18,155 Hmar speakers were found in Mizoram, but most of the Hmars of Mizoram speak Mizo languages. Religion An overwhelming majority of the Hmar people practice Christianity with a few Judaism (Bnei Menashe) . Place of origin The Hmars trace their origin to Sinlung, the location of which is hotly debated. The term “Hmar” is believed to have originated from the term “Hmerh” meaning “tying of one’s hair in a knot on the nape of one’s head”. According to Hmar tradition, there ...

Barak Valley
The Barak Valley is located in the southern region of the Indian state of Assam. The region is named after the Barak river. The Barak valley consists of three administrative districts of Assam - namely Cachar, Karimganj, and Hailakandi. The main, largest and capital city of the Valley is Silchar. Once North Cachar Hills was a part of the valley but In 1951 erstwhile Sub-Division was made a separate district and eventually curved out of Cachar. On 1 July 1983, Karimganj district was curved out from the eponymous subdivision of Cachar Valley. This was again repeated in 1989 with the creation of Hailakandi district. Etymology The name "Barak" has derived from the Dimasa words 'Bra' & 'Kro'. Bra means bifurcation and Kro upper means portion/stream. The river Barak is bifurcated near Haritikar in the Karimganj district in to Surma River and Kushiyara River respectively. The upstream of this bifurcated river was called Brakro by the local Dimasa people. Barak valley excludin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Richter Scale
The Richter scale —also called the Richter magnitude scale, Richter's magnitude scale, and the Gutenberg–Richter scale—is a measure of the strength of earthquakes, developed by Charles Francis Richter and presented in his landmark 1935 paper, where he called it the "magnitude scale". This was later revised and renamed the local magnitude scale, denoted as ML or . Because of various shortcomings of the original scale, most seismological authorities now use other similar scales such as the moment magnitude scale () to report earthquake magnitudes, but much of the news media still erroneously refers to these as "Richter" magnitudes. All magnitude scales retain the logarithmic character of the original and are scaled to have roughly comparable numeric values (typically in the middle of the scale). Due to the variance in earthquakes, it is essential to understand the Richter scale uses logarithms simply to make the measurements manageable (i.e., a magnitude 3 quake factors ...

Hydroelectric Power Stations In Manipur
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of 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.
