Ghatghar Dam
Ghatghar Dam refers to two associated gravity dams built using roller-compacted concrete, the first use in India. They are situated in Ghatghar village in Ahmednagar district Maharashtra, India. Both dams create a lower and upper reservoir for the 250 MW pumped-storage hydroelectric power station. The upper Ghatghar dam is tall and on the Pravara River, a tributary of Godavari river. The lower Ghatghar dam is tall and located on the Shahi Nalla which is a tributary of Ulhas River The Ulhas River is a river in Maharashtra, India. It is in the Thane, Raigad, and Pune districts of that state. It flows north and west from it source to where it splits into Vasai Creek and Thane Creek, near Thane. The Ulhas divides Salsett ... to the south west of the upper reservoir in a steep valley. The hydro power project diverts Godavari river basin water outside the basin area to a west flowing river of Western ghats. The power station is located between both the upper and lower r ...

Ulhas River
The Ulhas River is a river in Maharashtra, India. It is in the Thane, Raigad, and Pune districts of that state. It flows north and west from it source to where it splits into Vasai Creek and Thane Creek, near Thane. The Ulhas divides Salsette Island from the mainland, and is important for the water supply of Mumbai.https://censusindia.gov.in/2011census/dchb/2724_PART_B_DCHB_RAIGARH.pdf Gallery File:Ulhas River.jpg, Ulhas River at Kondhana village in Raigad district File:Ghodbunder2.jpg, The Ulhas River, as seen from Ghodbunder See also *List of rivers of India *Rivers of India The rivers in India play an important role in the lives of its people.

Gravity Dams
A gravity dam is a dam constructed from concrete or stone masonry and designed to hold back water by using only the weight of the material and its resistance against the foundation to oppose the horizontal pressure of water pushing against it. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section. Characteristics Gravity dams generally require stiff rock foundations of high bearing strength (slightly weathered to fresh), although in rare cases, they have been built on soil foundations. The bearing strength of the foundation limits the allowable position of the resultant force, influencing the overall stability. Also, the stiff nature of the gravity dam structure is unforgiving to differential foundation settlement, which can induce cracking of the dam structure. Gravity dams provide some advantages over embankment dams, the main advantage being that they can tolerate minor over-topping flows without damage, as the concre ...

Pumped-storage Hydroelectric Power Stations In India
Pumped-storage hydroelectricity (PSH), or pumped hydroelectric energy storage (PHES), is a type of hydroelectric energy storage used by electric power systems for load balancing. The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation. Low-cost surplus off-peak electric power is typically used to run the pumps. During periods of high electrical demand, the stored water is released through turbines to produce electric power. Although the losses of the pumping process make the plant a net consumer of energy overall, the system increases revenue by selling more electricity during periods of peak demand, when electricity prices are highest. If the upper lake collects significant rainfall or is fed by a river then the plant may be a net energy producer in the manner of a traditional hydroelectric plant. Pumped-storage hydroelectricity allows energy from intermittent sources (such as solar, win ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Energy Infrastructure Completed In 2008
In physics, energy (from Ancient Greek: ἐνέργεια, ''enérgeia'', “activity”) is the quantitative property that is transferred to a body or to a physical system, recognizable in the performance of work and in the form of heat and light. Energy is a conserved quantity—the law of conservation of energy states that energy can be converted in form, but not created or destroyed. The unit of measurement for energy in the International System of Units (SI) is the joule (J). Common forms of energy include the kinetic energy of a moving object, the potential energy stored by an object (for instance due to its position in a field), the elastic energy stored in a solid object, chemical energy associated with chemical reactions, the radiant energy carried by electromagnetic radiation, and the internal energy contained within a thermodynamic system. All living organisms constantly take in and release energy. Due to mass–energy equivalence, any object that has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dams Completed In 2006
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 earliest known dam is the Jawa Dam in Jordan, dating to 3,000 BC. 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. History Ancient dams Early dam building took place in Mesopotamia and the Middle East. Dams were used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
