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.

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 ...

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] |

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.

Lake Pancharevo
Lake Pancharevo (Панчаревско езеро, ''Pancharevsko ezero'' or Язовир Панчарево, ''Pancharevo Reservoir'') is an artificial lake in western Bulgaria, at the end of the Pancharevo Gorge of the Iskar River, located at 600 m above sea level between the Vitosha and Lozenska mountains. It is 3 km long and up to 700 m wide, reaching a depth of 30 m, and is situated 12 km southeast of the capital city of Sofia, where the Vitoshka Bistritsa flows into the Iskar (river), Iskar. The villages of Pancharevo and Kokalyane and the Pancharevo mineral springs lies on the lake's western shore, while at the southern end of the lake there is a Hydroelectricity, hydroelectric power station. Sports centres and catering establishments have been constructed around the lake, making it a favoured outing location for the residents of Sofia. Further upstream in the gorge there are two additional artificial lakes: the Pasarel Reservoir and the Iskar Reservoir. The lake w ...

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. Types Dammed valleys Dammed reservoirs are artificial lakes created and controlled by a dam constructed across a valley, and rely on the natural topography to provide most of the basin ...

Sofia
Sofia ( ; bg, София, Sofiya, ) is the capital and largest city of Bulgaria. It is situated in the Sofia Valley at the foot of the Vitosha mountain in the western parts of the country. The city is built west of the Iskar river, and has many mineral springs, such as the Sofia Central Mineral Baths. It has a humid continental climate. Being in the centre of the Balkans, it is midway between the Black Sea and the Adriatic Sea, and closest to the Aegean Sea. Known as Serdica in Antiquity and Sredets in the Middle Ages, Sofia has been an area of human habitation since at least 7000 BC. The recorded history of the city begins with the attestation of the conquest of Serdica by the Roman Republic in 29 BC from the Celtic tribe Serdi. During the decline of the Roman Empire, the city was raided by Huns, Visigoths, Avars and Slavs. In 809, Serdica was incorporated into the Bulgarian Empire by Khan Krum and became known as Sredets. In 1018, the Byzantines ended Bulgarian r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bulgaria
Bulgaria (; bg, България, Bǎlgariya), officially the Republic of Bulgaria,, ) is a country in Southeast Europe. It is situated on the eastern flank of the Balkans, and is bordered by Romania to the north, Serbia and North Macedonia to the west, Greece and Turkey to the south, and the Black Sea to the east. Bulgaria covers a territory of , and is the sixteenth-largest country in Europe. Sofia is the nation's capital and largest city; other major cities are Plovdiv, Varna and Burgas. One of the earliest societies in the lands of modern-day Bulgaria was the Neolithic Karanovo culture, which dates back to 6,500 BC. In the 6th to 3rd century BC the region was a battleground for ancient Thracians, Persians, Celts and Macedonians; stability came when the Roman Empire conquered the region in AD 45. After the Roman state splintered, tribal invasions in the region resumed. Around the 6th century, these territories were settled by the early Slavs. The Bulgars, led ...

Tailwater
Tailwater refers to waters located immediately downstream from a hydraulic structure, such as a dam, spillway, bridge or culvert. Generally measured and reported as the average water depth downstream of a hydraulic structure, tailwater can vary based on the outlet from the structure as well as downstream influences that may restrict or advance the usual flow of water from the structure. The creation of a tailwater will have significant impacts on both the Abiotic component, abiotic and Biotic material, biotic conditions of the waterway. Biotic Impacts The environmental conditions in a tailwater influence the entire food web of the waterway. Consistent flows, higher temperatures, and clear water found in tailwaters create an ideal habitat for filamentous green algae. The near-shore zones of tailwaters that are submerged during hydropeaking but dry during consistent flows are far less productive areas of the waterway. Most algal species are not adapted to handle this exposure to ai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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. Hydroelectric systems and dams Penstocks for hydroelectric installations are normally equipped with a gate system and a surge tank. They can be a combination of many components such as anchor block, drain valve, air bleed valve, and support piers depending on the application. Flow is regulated by turbine operation and is nil when turbines are not in service. Penstocks, particularly where used in polluted water systems, need to be maintained by hot water washing, manual cleaning, antifouling coatings, and desiccation. The term is also used in irrigation dams to refer to the channels leading to and from high-pressure sluice gates. Penstocks are also used in mine tailings dam construction. The penstock is usually situated fairly close to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
