On an island like Iceland, the rivers are short in length. None of the rivers are important as a means of navigation due to the impracticality of settlements in the Highlands of Iceland where they originate.
Jökulsá á Fjöllum is the second longest river in Iceland (206 km). Its source is the Vatnajökull glacier. It flows into the Greenland Sea. Jökulsá á Fjöllum streams over the waterfalls Selfoss, Dettifoss, Hafragilsfoss, and Réttarfoss, the second of which is the most powerful waterfall in Europe.
Kárahnjúkar Hydropower Plant, officially called Fljótsdalur Power Station is a hydroelectric power plant in Fljótsdalshérað municipality in eastern Iceland, designed to produce 4,600 gigawatt-hours (17,000 TJ) annually for Alcoa's Fjarðaál aluminum smelter 75 kilometres (47 mi) to the east in Reyðarfjörður. With the installed capacity of 690 megawatts (930,000 hp), the plant is the largest power plant in Iceland. The project, named after the nearby Kárahnjúkar mountains, involves damming the rivers Jökulsá á Dal and Jökulsá í Fljótsdal with five dams, creating three reservoirs. Water from the reservoirs is diverted through 73 kilometres (45 mi) of underground water tunnels and down a 420-metre (1,380 ft) vertical penstock towards a single underground power station. The smelter became fully operational in 2008 and the hydropower project was completed in 2009.
Öxarfjörður is a broad fjord in northeastern Iceland, situated between the Tjörnes and Melrakkaslétta headlands.
Hofsá is a river in Vopnafjörður in the Northeastern part of Iceland. It is 85 kilometres (53 mi) long and is a productive salmon river.
Lónsöræfi is a wilderness area in south-east Iceland. The region is characterised by its varied geological formations. These mostly date from a period between 5 and 7 million years ago, when the volcano Kollumúlaeldstöðvar was active. The glacier tongues of the eastern extreme of Vatnajökull also impose themselves on the area. Visible to the north-west is Snæfell (1833m), the highest peak in Iceland that isn't part of a glacier. The mountains within the area itself include Sauðhamarstindur (1319m) and Jökulgilstindar.
Jökulsá is the name of several rivers in Iceland.
Historically, Iceland was divided into four farthings corresponding to the cardinal directions. These were administrative divisions established in 965 for the purpose of organising regional assemblies called farthing assemblies (fjórðungsþing) and regional courts called farthing courts (fjórðungsdómar). Each farthing held three local assemblies, which were each presided over by three goðar or chieftains. The North Farthing alone held four. Farthing courts would judge cases if both plaintiff and defendant belonged to the same assembly; otherwise the case was brought to the general assembly, the Alþingi. Little else is known about these farthing courts and they seem to have been much more irregular than the spring and autumn assemblies. Also, in spite of the apparent regularity of three goðar per assembly and three to four assemblies per farthing, the system of rule by chieftains and assemblies probably followed a much more varied pattern.
Hafragilsfoss is a waterfall in Iceland.
The Hálslón Reservoir is a storage reservoir in Eastern Iceland on the Jökulsá á Dal River. The reservoir stores water for use in hydroelectricity production with the Kárahnjúkar Hydropower Plant. The reservoir was formed by three different concrete-faced, rock-filled embankment dams: the Kárahnjúkastífla Dam, the Desjarárstífla Dam and the Sauðárdalsstífla Dam.
Norðurá is a river that runs through the Borgarfjörður region in central west Iceland. It is a tributary of the Hvítá. Its origins are in Lake Holtavörðuvatn at 326 m altitude.
Héraðsvötn, whose name is often shortened to Vötn or Vötnin is a glacier river in Iceland. It is formed by the confluence of Austari-Jökulsá and Vestari-Jökulsá. The Héraðsvötn is located in Skagafjörður, a municipality in northern Iceland, and it is one of the deadliest waterfalls in the country.
Jökulsá á Dal, also called Jökulsá á Brú or Jökla, is a river in the northeast of Iceland.
Dyngjujökull is an outlet glacier of the Vatnajökull glacier in Vatnajökull National Park, Iceland. The glacier is in the Icelandic Highlands and is situated between Bárðarbunga, Holuhraun and Kverkfjöll. Meltwater from the glacier flows into Jökulsá á Fjöllum, the second longest river in Iceland.
Jökulsá is a river in Southeast Iceland in Austur-Skaftafellssýsla (municipality) in the middle of Breiðamerkursandur, a glacial outwash plain.
Austari-Jökulsá is a glacial river in the north of Iceland. After the confluence with Vestari-Jökulsá it forms the Héraðsvötn.
Rauðhólar (Vesturdalur) is a small chain of volcanoes within the Askja or the Fremrinámur volcanic systems in the north of Iceland.
Hvíti Riddarinn is a multi-sport club based in Mosfellsbær, Iceland. It was founded on 14 August 1998 and through its history has fielded departments in football, handball and basketball.
Vestari-Jökulsá or Jökulsá vestri is a glacier river in Skagafjörður, Iceland. It originates in the northwest corner of Hofsjökull and is formed from many branches that fall together and flow northward. The beginning of the river runs through relatively low-pitched and level land, through a deep canyon, called Þröngagil. It then follows the length of a valley finally falling into Vesturdalur to the northeast, where Hofsá flows into it. Hofsá runs briefly along Vesturdalur, before joining the Austari-Jökulsá at Tunguháll, at which point the rivers are known as the Héraðsvötn.
Norðurá is a river that runs the length of Norðurárdalur valley in Skagafjörður, Iceland, where it creates extensive sandbars on the valley floor. The river joins the Héraðsvötn below Flatatunga. Many tributaries flow into the Norðurá, some located in massive ravines, including Kotá, Valagilsá, Horná, Heiðará, Grjótá, Króká, Egilsá, Stóralækur rivers.
