Iskar Reservoir
The Iskar Reservoir (язовир „Искър“) is the largest reservoir in Bulgaria. It is situated on the Iskar River and provides 2/3 of the water for the capital Sofia, also being used for producing hydroelectricity. The reservoir has a total volume of 673 million m3, of which 580 million are in use and the rest is reserve. The reservoir has a drainage basin of 1,046 km² and is 25 km long. It is situated at 820 m above sea level, its dam being 204 m long and 76 m high. History The initial plans for the construction of a dam on the Iskar date to as early as 1900-1901, immediately after the building of the Pancharevo Hydroelectric Power Plant. In 1921, the idea was once again brought up, but its accomplishment failed due to the municipality's inability to indemnify the residents of the neighbouring villages of Gorni Pasarel, Shishmanovo and Kalkovo. Topographic photographs and a geological assessment regarding the dam were made and observations of the Iskar's w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Reservoir
A reservoir (; from French ''réservoir'' ) is an enlarged lake behind a dam. Such a dam may be either artificial, built to store fresh water or it may be a natural formation. Reservoirs can be created in a number of ways, including controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an embayment within it, through excavation, or building any number of retaining walls or levees. In other contexts, "reservoirs" may refer to storage spaces for various fluids; they may hold liquids or gasses, including hydrocarbons. ''Tank reservoirs'' store these in ground-level, elevated, or buried tanks. Tank reservoirs for water are also called cisterns. Most underground reservoirs are used to store liquids, principally either water or petroleum.

Topographic
Topography is the study of the forms and features of land surfaces. The topography of an area may refer to the land forms and features themselves, or a description or depiction in maps. Topography is a field of geoscience and planetary science and is concerned with local detail in general, including not only relief, but also natural, artificial, and cultural features such as roads, land boundaries, and buildings. In the United States, topography often means specifically ''relief'', even though the USGS topographic maps record not just elevation contours, but also roads, populated places, structures, land boundaries, and so on. Topography in a narrow sense involves the recording of relief or terrain, the three-dimensional quality of the surface, and the identification of specific landforms; this is also known as geomorphometry. In modern usage, this involves generation of elevation data in digital form (DEM). It is often considered to include the graphic representation of the ...

Reservoirs In Bulgaria ...
This is a list of reservoirs in Bulgaria: Note: In Bulgaria, a ''dam'' (''Bulgarian'' язовир) is often used to refer the body of water, rather than the structure. It signifies that the body of water is man-made instead of natural.

Soviet Union
The Soviet Union,. officially the Union of Soviet Socialist Republics. (USSR),. was a transcontinental country that spanned much of Eurasia from 1922 to 1991. A flagship communist state, it was nominally a federal union of fifteen national republics; in practice, both its government and its economy were highly centralized until its final years. It was a one-party state governed by the Communist Party of the Soviet Union, with the city of Moscow serving as its capital as well as that of its largest and most populous republic: the Russian SFSR. Other major cities included Leningrad (Russian SFSR), Kiev (Ukrainian SSR), Minsk ( Byelorussian SSR), Tashkent (Uzbek SSR), Alma-Ata (Kazakh SSR), and Novosibirsk (Russian SFSR). It was the largest country in the world, covering over and spanning eleven time zones. The country's roots lay in the October Revolution of 1917, when the Bolsheviks, under the leadership of Vladimir Lenin, overthrew the Russian Provisional Government ...

Pancharevo
Pancharevo ( bg, Панчарево, , also transcribed as Pančarevo) is a resort village and district located on the outskirts of Sofia close to Vitosha, Lozenska and Plana mountains and occupies the southeastern part of the Capital Municipality. the village has 3,433 inhabitants, but the district has about 28,000 inhabitants. It is the largest region in Sofia with a total area of . It includes the largest artificial lake in Bulgaria Lake Pancharevo, also as Iskar Reservoir and Pasarel Reservoir, located one above the other. The districts consists of 10 villages, and Pancharevo is the municipal seat: * Bistritsa * German * Kazichene * Kokalyane * Krivina * Lozen * Pancharevo * Pasarel * Plana * Zheleznitsa The district offers excellent conditions for relaxation and tourism for the citizens of the capital.

Pasarel
The Pasarel dam and reservoir is located 20 km to the southeast of Sofia, Bulgaria at an altitude of 700 m. The dam is situated roughly halfway between the Iskar Reservoir and Lake Pancharevo near the village of Dolni Pasarel. Though built in the Iskar valley, under most circumstances, the primary inflow come from the tailwater of a co-located hydroelectric plant (which is in turn is fed from a long, underground penstock A penstock is a sluice or gate or intake structure that controls water flow, or an enclosed pipe that delivers water to hydro turbines and sewerage systems. The term is inherited from the earlier technology of mill ponds and watermills. H ... from the Iskar Reservoir.) Likewise, in most cases, the majority of its outflow goes into another long penstock to the hydroelectric plant at the southern end of Lake Pancharevo. The reservoir itself is small (about 1.5 km long and 300 m wide), but still attracts visitors to the area. Near to the Pasare ...

Geological
Geology () is a branch of natural science concerned with Earth and other astronomical objects, the features or rocks of which it is composed, and the processes by which they change over time. Modern geology significantly overlaps all other Earth sciences, including hydrology, and so is treated as one major aspect of integrated Earth system science and planetary science. Geology describes the structure of the Earth on and beneath its surface, and the processes that have shaped that structure. It also provides tools to determine the relative and absolute ages of rocks found in a given location, and also to describe the histories of those rocks. By combining these tools, geologists are able to chronicle the geological history of the Earth as a whole, and also to demonstrate the age of the Earth. Geology provides the primary evidence for plate tectonics, the evolutionary history of life, and the Earth's past climates. Geologists broadly study the properties and processes of Ear ...
