Deduru Oya Dam
The Deduru Oya Dam is an embankment dam built across the Deduru River in Kurunegala District of Sri Lanka. Built in 2014, the primary purpose of the dam is to retain for irrigation purposes approximately a billion cubic metres of water, which would otherwise flow out to sea. Site studies of the dam began in 2006 and construction started in 2008. It was ceremonially completed in 2014, with the presence of then President Mahinda Rajapaksa. Site studies and design of the dam was done by engineers from the Ministry of Irrigation. The dam, which measures approximately wide, creates the Deduru Oya Reservoir, which has a capacity of . Water from the reservoir is used to irrigate approximately of farmland, while also powering a hydroelectric power station, operated by the Ministry of Power and Energy. In addition to the eight sluice gates, water from the reservoir is channelled from the reservoir (for irrigation) via three canals, namely the ''Left Canal'', ''Central Canal'', and ...

Hydroelectric Power Stations In Sri Lanka
Hydroelectricity, or hydroelectric power, is 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 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.

Embankment Dams
Embankment may refer to: Geology and geography * A levee, an artificial bank raised above the immediately surrounding land to redirect or prevent flooding by a river, lake or sea * Embankment (earthworks), a raised bank to carry a road, railway, or canal across a low-lying or wet area * Embankment dam, a dam made of mounded earth and rock * Land reclamation along river banks, usually marked by roads and walkways running along it, parallel to the river, as in: ** The Thames Embankment along the north side of the Thames River in London, England *** The Victoria Embankment contained within the Thames Embankments *** The Chelsea Embankment contained within the Thames Embankment ** The Albert Embankment Albert Embankment is part of the river bank on the south side of the River Thames in Central London.

Dams In Sri Lanka
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 dams, ...

List Of Power Stations In Sri Lanka
Sri Lanka's electricity demand is currently met by nine thermal power stations, fifteen large hydroelectric power stations, and fifteen wind farms, with a smaller share from small hydro facilities and other renewables such as solar. Most hydroelectric and thermal/fossil fuel–based power stations in the country are owned and/or operated by the government via the state-run Ceylon Electricity Board (CEB), while the renewable energy sector consists mostly of privately run plants operating on a power purchase agreement with the CEB. Per CEB's 2016 generation report released in mid-2017, the country has a total combined installed generation capacity of , of which 2,115 MW (52.65%) was from thermal (900 MW/22.40% from coal and 1,215 MW/30.25% from fuel oil), 1,726 MW (42.97%) from hydroelectricity, and the remaining 176 MW (4.38%) from other renewable sources such as wind, biomass, and solar. These generation sources produced a total of of electricity during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Dams And Reservoirs In Sri Lanka
The following page lists most dams in Sri Lanka. Most of these dams are governed by the Mahaweli Authority, while the Ceylon Electricity Board operates dams used for Hydroelectricity#Generating methods, hydroelectric power generation. Hydroelectric dams, including small hydros, account for nearly half of the installed power capacity of Sri Lanka. Sri Lanka is pockmarked with many irrigation dams, with its water resource distributed across nearly the entirety of the island for agricultural purposes via artificial canals and streams. Utilization of hydro resources for agricultural production dates back to the History of Sri Lanka, pre-Colonial era, with the current crop production now largely dependent on these water resources. __NOTOC__ Dams in Sri Lanka Irrigation dams with a length and height of more than and are listed, including all the state-run hydroelectric power stations.

Megawatt
The watt (symbol: W) is the unit of Power (physics), power or radiant flux in the 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 Work (physics), energy transfer. The watt is named in honor of James Watt (1736–1819), an 18th-century Scottish people, Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own Watt steam engine, steam engine in 1776, which became fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one meter 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 potential difference of one volt (V), meaning the watt is equivalent to the vo ...
