Oymapınar Dam
Oymapinar Dam is an arch dam built on the Manavgat river in Turkey in 1984. It is an arch dam in design, 185 m in height, built to generate hydroelectric power. Oymapınar Dam is located 12 km north of Manavgat Waterfall. It is an artificial, freshwater dam with a capacity of 300 million cubic meters. It is 23 km upstream of Manavgat town 40 km east of city of Antalya in southern Turkey and located on the Manavgat River which runs into the Mediterranean. Description The dam has four underground turbines with a total capacity of 540 megawatts. When built in 1984 it was the third largest dam in Turkey. As more dams have been built, it is the fifth largest. Because of the arch design, the force of water pushing against the dam compacts the dam and strengthens it. The weight of the dam structure pushes it down firmly into the underlying rock. This design is ideal for dams built in rocky narrow gorges. Construction The dam was designed in the USSR and built by B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Manavgat River
Manavgat River originates on the eastern slopes of Western Taurus Mountains in Turkey. In ancient times it was called Melas ( grc, Μέλας). At an elevation of 1,350 m, the outflow of several small springs joins together to become the headwaters of the Manavgat. The largest of these springs is called Dumanli, whose name means "place where there is fog", because of the dense mist that forms above the spring. In addition to the springs from the Taurus Mountains, the Manavgat is also fed underground from large lakes to the north of the mountains, on the Anatolian Plateau. Pliny the Elder considered that the river was the boundary between ancient Pamphylia and Cilicia. From there, the river flows south over conglomerated strata for about 90 km, descending through a series of canyons. Finally, it washes over the Manavgat Waterfall and through the coastal plain and into the Mediterranean Sea. There are many caves in the river watershed area, the most interesting being the Altın ...

Arch Dam
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. Classification In general, arch dams are classified based on the ratio of the base thickness to the structural height (b/h) as: * Thin, for b/h less than 0.2, * Medium-thick, for b/h between 0.2 and 0.3, and * Thick, for b/h ratio over 0.3. Arch dams classified with respect to their structural height are: * Low dams up to , * Medium high dams between , * High dams over . History The developme ...

Hydroelectric
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.

Manavgat Waterfall
Manavgat Waterfall on the Manavgat River is near the city of Side, north of Manavgat, Turkey. Its high flow over a wide area as it falls from a low height is best viewed from a high altitude. The white, foaming water of the Manavgat Waterfalls flows powerfully over the rocks. Near the waterfalls are shady tea gardens providing a pleasant resting place. The Oymapinar Dam is located to the north of the river. During floods, the Manavgat Falls may disappear under high water. The waterfall was depicted on the reverse of the Turkish 5 lira Lira is the name of several currency units.

Mediterranean
The Mediterranean Sea is a sea connected to the Atlantic Ocean, surrounded by the Mediterranean Basin and almost completely enclosed by land: on the north by Western and Southern Europe and Anatolia, on the south by North Africa, and on the east by the Levant. The Sea has played a central role in the history of Western civilization. Geological evidence indicates that around 5.9 million years ago, the Mediterranean was cut off from the Atlantic and was partly or completely desiccated over a period of some 600,000 years during the Messinian salinity crisis before being refilled by the Zanclean flood about 5.3 million years ago. The Mediterranean Sea covers an area of about , representing 0.7% of the global ocean surface, but its connection to the Atlantic via the Strait of Gibraltar—the narrow strait that connects the Atlantic Ocean to the Mediterranean Sea and separates the Iberian Peninsula in Europe from Morocco in Africa—is only wide.

Bilfinger Berger
Bilfinger SE (previously named Bilfinger Berger AG) is a German company specialized in civil and industrial construction, engineering and services based in Mannheim, Germany. History Bilfinger dates back to 1880 when August Bernatz founded Bernatz Ingenieurwissenschaft as an engineering business: it became known, from 1886 as Bernatz & Grün and, from 1892, as Grün & Bilfinger when Paul Bilfinger replaced Bernatz as partner. During the Second World War, Grün & Bilfinger employed Jewish slave laborers from the Kovno Ghetto in occupied Lithuania where it was known for its brutal harassment of the Jewish slaves. In 1970, Grün & Bilfinger acquired a majority stake in Julius Berger-Bauboag AG, itself a merger of two companies, Julius Berger Tiefbau AG and Berlinische Boden-Gesellschaft AG, both founded in 1890. The combined business, fully integrated in 1975, finally took the name Bilfinger & Berger Bauaktiengesellschaft. In 1994 the acquisition of Razel Company took place. I ...

Dams In Antalya Province
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 us ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
