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 are used to manage or prevent water flow into specific land regions.
Lake Gordon is a man-made reservoir created by the Gordon Dam, located on the upper reaches of the Gordon River in the south-west region of Tasmania, Australia.
In engineering, a foundation is the element of a structure which connects it to the ground or more rarely, water, transferring loads from the structure to the ground. Foundations are generally considered either shallow or deep. Foundation engineering is the application of soil mechanics and rock mechanics in the design of foundation elements of structures.
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. Gravity dams are designed so that each section of the dam is stable and independent of any other dam section.
An arch dam is a concrete dam that is curved upstream in plan. The arch dam is designed so that the force of the water against it, known as hydrostatic pressure, presses against the arch, causing the arch to straighten slightly and strengthening the structure as it pushes into its foundation or abutments. An arch dam is most suitable for narrow canyons or gorges with steep walls of stable rock to support the structure and stresses. Since they are thinner than any other dam type, they require much less construction material, making them economical and practical in remote areas.
Karkamış Dam is one of the 21 dams of the Southeastern Anatolia Project of Turkey. It is on the Euphrates River. The foundation of the dam was laid in 1996, and is 4.5 kilometres (2.8 mi) from the Syria border. The hydroelectric power plant has a total installed power capacity of 189 megawatts (253,000 hp).
Mattupetty Dam, near Munnar in Idukki District, is a storage concrete gravity dam built in the mountains of Kerala, India to conserve water for hydroelectricity. It has been a vital source of power and huge revenue for Idukki District. The large amount of perennially available water allows wild animals and birds to flourish. Construction of the dam was led by E.U. Philipose, Superintending Engineer, Kerala State Electricity Board. The height of the dam is 83.35 metres (273.5 ft) and the length is 237.74 metres (780.0 ft). Taluks through which the release flows are Udumpanchola, Devikulam, Kothamangalam, Muvattupuzha, Kunnathunadu, Aluva, Kodungalloor and Paravur.
The Loch Raven Reservoir is a reservoir that provides drinking water for the City of Baltimore and most of Baltimore County, Maryland. It is fed by the Big Gunpowder Falls river, and has a capacity of 23 billion US gallons (87,000,000 m3) of water.
Ely's Stone Bridge is a bridge that was listed on the National Register of Historic Places in 1979. The bridge was built across Deer Creek in 1893 by Reuben Ely, Sr., a farmer, and his son Reuben Ely, Jr. The bridge is a three-span arch bridge made of stone from the stream bed and quarries in Anamosa, Iowa.
Alpaslan-1 Dam is a dam and hydroelectric power station in Muş Province, Turkey. The foundation stone for the dam was laid in 1994 and construction on the dam superstructure began in 1998. The dam began to impound its reservoir in 2008 and the first of four 40 MW generators was operational in 2009. The second was commissioned in 2012.
Karadere Dam is a dam in Kastamonu Province, Turkey, built between 1993 and 2007. The development was backed by the Turkish State Hydraulic Works. Karadere Dam is built for irrigation purposes and can be found between Kastamonu and Taşköprü. The scope of work includes 1,500,000 cubic metres (53,000,000 cu ft) of excavation and 3,000,000 m3 (110,000,000 cu ft) of fill. It has a 497-metre (1,631 ft) long diversion tunnel which is 3.5 metres (11 ft) in diameter.
Kozlu Dam is a dam in Zonguldak Province, Turkey, built between 1979 and 1986. The development was backed by the Turkish State Hydraulic Works.
The Dibang Dam is a planned concrete gravity dam, located in the Lower Dibang Valley District in Arunachal Pradesh, India. If constructed, it will be India's largest dam and the world's tallest concrete gravity dam, standing 288 metres (945 ft) tall. The Dibang Dam is expected to provide up to 3,000 megawatts of hydroelectric power and will also assist with flood control in the Dibang Valley.
The Thenmala Dam also known as Parappar Dam is part of the largest irrigation project in Kerala, India. It is built along Kallada River in Kollam district of Kerala. The reservoir is used for irrigation and power generation.
The Durgavati River, which flows through Kaimur district in the Indian state of Bihar, is a tributary of the Karmanasa.
The Kurram Tangi Dam is a multipurpose dam under construction on the Kaitu River in North Waziristan, Pakistan, with a 83.4 MW power generation capacity.
Dharoi Dam is a gravity dam on the Sabarmati river near Dharoi, Satlasana Taluka, and Mehsana districts of northern Gujarat in India. Completed in 1978, the dam is meant for irrigation, power generation and flood control.
The Artvin Dam an arch-gravity dam on the Çoruh River in Artvin Province, Turkey. Preliminary construction on the dam began in December 2010 and the river diversion tunnels were complete in July 2012 at which time construction on the dam foundation started. The purpose of the dam is hydroelectric power generation and its power station has an installed capacity of 340 MW when completed. The dam is part of the Çoruh Development Plan and its construction was supervised by Turkey's State Hydraulic Works. The dam began to impound its reservoir in October 2015 and the power station was commissioned beginning in January 2016.
Smith Mountain Cooperative Wildlife Management Area is a 4,996-acre (20.22 km2) Wildlife Management Area (WMA) in Bedford and Pittsylvania counties, Virginia. Located on the shores of Smith Mountain Lake, the WMA is owned by Appalachian Power and cooperatively managed by the Virginia Department of Game and Inland Fisheries and the Virginia Outdoors Foundation through a conservation easement that permits public access.
The Beaver Dam pepper is a Capsicum annuum cultivar derived from seeds brought to Beaver Dam, Wisconsin, by Hungarian immigrant Joe Hussli in 1912. It is listed in the Slow Food Foundation's "Ark of Taste", and is the subject of an annual festival held in Beaver Dam each September.
