Otra Vaina
The Otra is the largest river in the Sørlandet region of Norway. It begins in Setesdalsheiene mountains at the lake Breidvatnet in Bykle municipality in Agder county, just south of the border with Vinje municipality in Vestfold og Telemark county. The river then flows south through Bykle, Valle, Bygland, Evje og Hornnes, Iveland, Vennesla, and Kristiansand municipalities. The river empties into the Skagerrak in the center of the city of Kristiansand on the southern coast of Norway. The Otra is long, making it Norway's eighth-longest river. There are many large lakes along the river including: Åraksfjorden, Byglandsfjorden, Hartevatnet, and Kilefjorden. There are 12 hydroelectric power plants built along the river, which produce much of the electricity for the southern part of Norway. The salmon do well in the Otra river because the water is not too acidic. The calcareous rocks in the catchment area at the northern end of the Setesdal valley give the water a certain ...

Vestfold Og Telemark
Vestfold og Telemark (; ) is a county under disestablishment in Norway. The county is the southernmost one of Eastern Norway and consists of two distinct and separate traditional regions: the former counties of Telemark and (most of) Vestfold. The capital is located at the town of Skien, which is also the county's largest city. While Skien is the seat of the county municipality, the seat of the County Governor is Tønsberg. It borders the counties of Viken, Vestland, Rogaland and Agder. Telemark voted against the merger, on the basis that the regions have nothing in common and do not constitute a natural geographical, cultural, social or political entity. Regardless, the Storting voted on 7 January 2018 to merge the counties by force, and the merger took effect on 1 January 2020. Unlike Telemark or Vestfold, it does not form a traditional or cultural region, but is instead administrative. On 15 February 2022, the county council decided to vote for the future of Vestfold og Telem ...

Rivers Of Agder
A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river. In some cases, a river flows into the ground and becomes dry at the end of its course without reaching another body of water. Small rivers can be referred to using names such as creek, brook, rivulet, and rill. There are no official definitions for the generic term river as applied to geographic features, although in some countries or communities a stream is defined by its size. Many names for small rivers are specific to geographic location; examples are "run" in some parts of the United States, "burn" in Scotland and northeast England, and "beck" in northern England. Sometimes a river is defined as being larger than a creek, but not always: the language is vague. Rivers are part of the water cycle. Water generally collects in a river from precipitation through a drainage basin from surface runoff and other sources such as groundwater recharge, springs, a ...

Setesdal
Setesdal (; older name: Sætersdal) is a valley and a traditional district in Agder County in southern Norway. It consists of the municipalities of Bykle, Valle, Bygland, Iveland, and Evje og Hornnes. The Otra river flows through the valley of Setesdal into the sea near Kristiansand. It flows southward from the Hardangervidda plateau in Telemark. The historic Setesdal starts at Evje and extends as far as the farm Bjåen, at the edge of the traditional region of Telemark. Øvre (Upper) Setesdal is in the municipality of Bykle. The municipalities of Iveland, Evje & Hornes and Bygland comprise the Nedre (Lower) Setesdal. Valle municipality is in the middle of the Setesdal valley. Norwegian National Road 9 runs through Setesdal. Etymology The oldest Norse form of the name was just ''Setr'', and this was later replaced by ''Setrsdalr'' ('the dale/valley of Setr'). The common word ''setr'' has the meaning 'homestead, farm' – and ''Setr'' was probably originally the name of an ol ...

Calcareous
Calcareous () is an adjective meaning "mostly or partly composed of calcium carbonate", in other words, containing lime or being chalky. The term is used in a wide variety of scientific disciplines. In zoology ''Calcareous'' is used as an adjectival term applied to anatomical structures which are made primarily of calcium carbonate, in animals such as gastropods, i.e., snails, specifically about such structures as the operculum, the clausilium, and the love dart. The term also applies to the calcium carbonate tests of often more or less microscopic Foraminifera. Not all tests are calcareous; diatoms and radiolaria have siliceous tests. The molluscs are calcareous, as are calcareous sponges ( Porifera), that have spicules which are made of calcium carbonate. In botany ''Calcareous grassland'' is a form of grassland characteristic of soils containing much calcium carbonate from underlying chalk or limestone rock. In medicine The term is used in pathology, for example i ...

Acidic
In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a single logical operation on the data) is called a ''transaction''. For example, a transfer of funds from one bank account to another, even involving multiple changes such as debiting one account and crediting another, is a single transaction. In 1983, Andreas Reuter and Theo Härder coined the acronym ''ACID'', building on earlier work by Jim Gray who named atomicity, consistency, and durability, but not isolation, when characterizing the transaction concept. These four properties are the major guarantees of the transaction paradigm, which has influenced many aspects of development in database systems. According to Gray and Reuter, the IBM Informa ...

Salmon
Salmon () is the common name for several list of commercially important fish species, commercially important species of euryhaline ray-finned fish from the family (biology), family Salmonidae, which are native to tributary, tributaries of the North Atlantic (genus ''Salmo'') and North Pacific (genus ''Oncorhynchus'') basin. Other closely related fish in the same family include trout, Salvelinus, char, Thymallus, grayling, Freshwater whitefish, whitefish, lenok and Hucho, taimen. Salmon are typically fish migration, anadromous: they hatch in the gravel stream bed, beds of shallow fresh water streams, migrate to the ocean as adults and live like sea fish, then return to fresh water to reproduce. However, populations of several species are restricted to fresh water throughout their lives. Folklore has it that the fish return to the exact spot where they hatched to spawn (biology), spawn, and tracking studies have shown this to be mostly true. A portion of a returning salmon run ma ...

Store Norske Leksikon
The ''Great Norwegian Encyclopedia'' ( no, Store Norske Leksikon, abbreviated ''SNL''), is a Norwegian-language online encyclopedia. The online encyclopedia is among the most-read Norwegian published sites, with more than two million unique visitors per month. Paper editions 1978–2007 The ''SNL'' was created in 1978, when the two publishing houses Aschehoug and Gyldendal merged their encyclopedias and created the company Kunnskapsforlaget. Up until 1978 the two publishing houses of Aschehoug and Gyldendal, Norway's two largest, had published ' and ', respectively. The respective first editions were published in 1907–1913 (Aschehoug) and 1933–1934 (Gyldendal). The slump in sales for paper-based encyclopedias around the turn of the 21st century hit Kunnskapsforlaget hard, but a fourth edition of the paper encyclopedia was secured by a grant of ten million Norwegian kroner from the foundation Fritt Ord in 2003. The fourth edition consisted of 16 volumes, a t ...

Hydroelectricity
Hydroelectricity, or hydroelectric power, is Electricity generation, 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 energy, renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of Low-carbon power, 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.

Kilefjorden
Kilefjorden is a lake on in Agder county, Norway. The lake is located on the border of the municipalities of Evje og Hornnes, Iveland, and Vennesla. The lake is part of the river Otra. The lake is located about west of the village of Birketveit in Iveland, about north of the village of Hægeland in Vennesla, and about south of the village of Hornnes in Evje og Hornnes. The steamship Bjoren worked in this lake from 1866–1896 transporting people and items across the lake. In 1896, the boat was moved to the Byglandsfjorden. The Norwegian National Road 9 runs along the southwestern end of the lake. Prior to 1950, the lake's outflow was at the waterfall ''Soga'' on the southeast end of the lake. In 1950, the Gåseflå dam was built further upstream creating the lake Gåseflåfjorden which adjoins the Kilefjorden at the same surface elevation so the waterfall is now underwater and it can only be seen when the lake Gåseflå is lowered for work on the power station.
