Ogulinska Dobra
The Dobra () is a river located mostly in the Karlovac County in the Republic of Croatia. It is long and its basin covers an area of . Its name is the feminine form of the Croatian adjective meaning "good" but it is over simplistic folk etymology. The river name probably comes from the Celtic , meaning ‘water’, Illyrian δυβρις () ‘deep’ or Old Slavonic dъbrь (, ) also ‘deep’ or ‘valley’. Dobra rises in Gorski Kotar near Skrad and Ravna Gora, where it flows first to the north and then turns to the east. It flows past Vrbovsko, to the southeast into the city of Ogulin, where it becomes an underground stream. It takes a sharp northward turn and rises back to the surface north of Ogulin. It continues to the northeast, past the Lešće spa and a hydroelectric plant (built and in test operation ), running in parallel to the Kupa and Mrežnica, and finally flows into the Kupa north of Karlovac. The Dobra river is rich in ichthyofauna and ornithofauna. The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kupa
The Kupa () or Kolpa ( or ; from la, Colapis in Roman times; hu, Kulpa) river, a right tributary of the Sava, forms a natural border between north-west Croatia and southeast Slovenia. It is long, with its border part having a length of and the rest located in Croatia. Name The name ''Colapis'', recorded in antiquity, is presumed to come from the Proto-Indo-European roots ''*quel-'' 'turn, meander' and ''*ap-'' 'water', meaning 'meandering water'. An alternative interpretation is ''*(s)kel-''/''*skul-'' 'shiny, bright', meaning 'clear river'. Course The Kupa originates in Croatia in the mountainous region of Gorski Kotar, northeast of Rijeka, in the area of Risnjak National Park. It flows a few kilometers eastwards, receives the small Čabranka River from the left, before reaching the Slovenian border. It then continues eastwards between the White Carniola region in the north and Central Croatia in the south. The Kupa receives influx from the river Lahinja from the left ...

Karlovac
Karlovac () is a city in central Croatia. According to the 2011 census, its population was 55,705. Karlovac is the administrative centre of Karlovac County. The city is located on the Zagreb- Rijeka highway and railway line, south-west of Zagreb and from Rijeka. Name The city was named after its founder, Charles II, Archduke of Austria. The German name ''Karlstadt'' or ''Carlstadt'' ("Charlestown") has undergone translation into other languages: in Hungarian it is known as ''Károlyváros'', in Italian as ''Carlovizza'', in Latin as ''Carolostadium'', and in Kajkavian and Slovene as Karlovec. History The Austrians built Karlovac from scratch in 1579 in order to strengthen their southern defences against Ottoman encroachments. The establishment of a new city-fortress was a part of the deal between the Protestant nobility of Inner Austria and the archduke Charles II of Austria. In exchange for their religious freedom the nobility agreed to finance the building of a new fort ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Bukovnik
A lake is an area filled with water, localized in a basin, surrounded by land, and distinct from any river or other outlet that serves to feed or drain the lake. Lakes lie on land and are not part of the ocean, although, like the much larger oceans, they do form part of the Earth's water cycle. Lakes are distinct from lagoons, which are generally coastal parts of the ocean. Lakes are typically larger and deeper than ponds, which also lie on land, though there are no official or scientific definitions. Lakes can be contrasted with rivers or streams, which usually flow in a channel on land. Most lakes are fed and drained by rivers and streams. Natural lakes are generally found in mountainous areas, rift zones, and areas with ongoing glaciation. Other lakes are found in endorheic basins or along the courses of mature rivers, where a river channel has widened into a basin. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydroelectric Power Plant Gojak
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.

Volume Flow
In physics and engineering, in particular fluid dynamics, the volumetric flow rate (also known as volume flow rate, or volume velocity) is the volume of fluid which passes per unit time; usually it is represented by the symbol (sometimes ). It contrasts with mass flow rate, which is the other main type of fluid flow rate. In most contexts a mention of ''rate of fluid flow'' is likely to refer to the volumetric rate. In hydrometry, the volumetric flow rate is known as ''discharge''. Volumetric flow rate should not be confused with volumetric flux, as defined by Darcy's law and represented by the symbol , with units of m3/(m2·s), that is, m·s−1. The integration of a flux over an area gives the volumetric flow rate. The SI unit is cubic metres per second (m3/s). Another unit used is standard cubic centimetres per minute (SCCM). In US customary units and imperial units, volumetric flow rate is often expressed as cubic feet per second (ft3/s) or gallons per minute (either ...

Dobra Bridge (A6)
Dobra Bridge is located between the Vrbovsko and Ravna Gora interchanges of the A6 motorway in Gorski Kotar, Croatia, spanning Dobra River. It is long and carries the motorway across five spans. The bridge consists of two parallel structures, both completed in 2003 by Primorje. The bridge is tolled within the A6 motorway ticket system and there are no separate toll plazas associated with use of the bridge. The bridge is located in a water protection area. Traffic volume Traffic is regularly counted and reported by Autocesta Rijeka–Zagreb, operator of the viaduct and the A6 motorway where the structure is located, and published by Hrvatske ceste. Substantial variations between annual (AADT) and summer (ASDT) traffic volumes are attributed to the fact that the bridge carries substantial tourist traffic to the Adriatic resorts. The traffic count is performed using analysis of motorway toll ticket sales. See also *List of bridges by length This is a list of the world ...

Dobra Bridge (A1)
The Dobra Bridge is located between Karlovac and Novigrad interchanges of the A1 motorway in Croatia, spanning Dobra River. It is long, and it comprises four traffic lanes and two emergency lanes. Construction work on the Dobra Bridge started in 1999 and was completed in 2001. Cost of the construction work was 57 million Croatian kuna (7.7 million euro). During the construction there was one major incident: on 1 July 2000, three girders plummeted from the main span piers into the river below. The incident did not cause any injury and damage was reported to be marginal. Description The deck structure stretches across 13 spans. The main span is long, while the remaining 12 spans are either or long. The bridge is executed as two parallel structures, each wide. The bridge is a reinforced concrete plate gider structure, consisting of pretensioned reinforced concrete prefabricated I-section girders tall and a deep reinforced concrete deck slab. Foundations of the bri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Power Plant
A power station, also referred to as a power plant and sometimes generating station or generating plant, is an industrial facility for the generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more generators, a rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a conductor creates an electric current. The energy source harnessed to turn the generator varies widely. Most power stations in the world burn fossil fuels such as coal, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and an increasing use of renewables such as solar, wind, geothermal, and hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerful enough to produce power on a commercial scale for industry. In 1878, a hydroelectric power station was designed and built by Wil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gojak Hydroelectric Power Plant
Gojak Hydroelectric Power Plant is a hydroelectric power plant on river Dobra, near the town of Ogulin, in Karlovac County, Croatia. Its total capacity is 55.5 MW. The Gojak Hydroelectric Power Plant is a high pressure diversion plant which harnesses the river power of the Ogulinska Dobra and Zagorska Mrežnica rivers. It is operated by the Croatian state-owned electrical company, Hrvatska elektroprivreda. Another lake is formed by the river Dobra just before it plunges into Đula's abyss. Namely, somewhere around one kilometer away from the center of Ogulin, a dam was built on the river Dobra, and in this way another artificial lake, Bukovnik, was created. From that lake, water is drained through channels up to 30 kilometers long to the Gojak Hydroelectric Power Station, where we use it to obtain electricity.
