Sultartangalón
The lake Sultartangarlón () is situated in the Highlands of Iceland to the north of the volcano Hekla. It is a reservoir of the river Þjórsá. Its surface area is 20 km2. Many reservoirs have been constructed and are being constructed in the highlands, which raises questions in Icelandic society about the roles and interests of industry and environment.

Tungnaá
The Tungnaá () is a river in the southern Highlands of Iceland. It flows from the western edge of Vatnajökull to the reservoir Sultartangalón, where it joins the Þjórsá. The river has been used extensively for hydroelectricity, with power stations at Vatnsfell, Sigalda, Hrauneyjafoss, and Sultartangi. See also *List of rivers of Iceland
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.

List Of Lakes Of Iceland
Iceland has over 20 lakes larger than 10 km2 (4 sq mi), and at least 40 others varying between 2.5 and 10 km2 (1 to 4 sq mi) in size. This list also includes a few smaller lakes and ponds that are considered notable (for example Tjörnin in Reykjavik). The figures for many of the smaller lakes are unreliable. Also, some larger lakes vary considerably in size between years or seasons or, for the reservoirs, according to the needs of power plants. Some power plant reservoirs may not be present despite being larger than listed lakes. Larger lakes (>10 km2) Smaller lakes (90 m (sensitive to climatic and geological change and was getting smaller - started recovering again in 2004) * Breiðárlón Breiðárlón () is a glacier lake at the south end of the Icelandic glacier Vatnajökull.

Highlands Of Iceland
The Highland (Icelandic language, Icelandic: ''Hálendið)'' or The Central Highland is an area that comprises much of the interior land of Iceland. The Highland is situated above and is mostly uninhabitable. The soil is primarily volcanic ash, and the terrain consists of basalt mountains and lava fields. Snow covers the Highland from October until the beginning of June. A few oasis-like areas, such as Herðubreiðarlindir and Thórsmörk, Þórsmörk, are also found in the Highland. The area has many notable natural features and hiking trails. Natural features in the Highland The Highland encompasses various geological features, including Landmannalaugar, Torfajökull, Eldgjá, Thórsmörk, Þórsmörk, Herðubreið, Askja, Hveradalir, Laki, Lakagígar, and the Fagrifoss waterfall. Sites in the Highland are difficult to access and may be accessible only during the summer months. Most sites require all-wheel drive or all-terrain vehicles for access due to the unpaved dirt ro ...

Reservoir
A reservoir (; ) is an enlarged lake behind a dam, usually built to water storage, store fresh water, often doubling for hydroelectric power generation. Reservoirs are created by controlling a watercourse that drains an existing body of water, interrupting a watercourse to form an Bay, embayment within it, excavating, or building any number of retaining walls or levees to enclose any area to store water. 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 of the reservoir. These reservoirs can either be ''on-stream reservoirs'', which are located on the original streambed of the downstream river and are filled by stream, creeks, rivers or rainwater that surface runoff, runs off the surrounding forested catchments, or ''off-stream reservoirs'', which receive water diversion, diverted water from a nearby stream or aqueduct (water supply), aq ...

Þjórsá
Þjórsá () is Iceland's longest river at . It is in the south of the island. Þjórsá is a glacier river and has its source on the glacier Hofsjökull. It flows out through narrow gorges in the highlands of Iceland. Further downstream, another river, the Tungnaá, flows into it (see also Háifoss), before it enters the lowlands. There it passes the valley of Þjórsárdalur (Thjorsardalur) where the historical farm of Stöng is located. In the lowlands it flows along the eastern border of the Great Þjórsá Lava. In the middle of the now rather wide river, there is a big island called '' Árnes'' , where there used to be a '' Þing''. The administrative unit of Árnessýsla was named after it. The '' hringvegur'' (Road No. 1) traverses the river via a bridge between Selfoss and Hella. Some distance to the southwest the river flows into the Atlantic Ocean The Atlantic Ocean is the second largest of the world's five borders of the oceans, oceanic divisions, ...

Iceland
Iceland is a Nordic countries, Nordic island country between the Atlantic Ocean, North Atlantic and Arctic Oceans, on the Mid-Atlantic Ridge between North America and Europe. It is culturally and politically linked with Europe and is the region's westernmost and most list of countries and dependencies by population density, sparsely populated country. Its Capital city, capital and largest city is Reykjavík, which is home to about 36% of the country's roughly 380,000 residents (excluding nearby towns/suburbs, which are separate municipalities). The official language of the country is Icelandic language, Icelandic. Iceland is on a rift between Plate tectonics, tectonic plates, and its geologic activity includes geysers and frequent Types of volcanic eruptions, volcanic eruptions.

Lake
A lake is often a naturally occurring, relatively large and fixed body of water on or near the Earth's surface. It is localized in a basin or interconnected basins surrounded by dry land. Lakes lie completely on land and are separate from the ocean, although they may be connected with the ocean by rivers. Lakes, as with other bodies of water, are part of the water cycle, the processes by which water moves around the Earth. Most lakes are fresh water and account for almost all the world's surface freshwater, but some are salt lakes with salinities even higher than that of seawater. Lakes vary significantly in surface area and volume of water. Lakes are typically larger and deeper than ponds, which are also water-filled basins on land, although there are no official definitions or scientific criteria distinguishing the two. Lakes are also distinct from lagoons, which are generally shallow tidal pools dammed by sandbars or other material at coastal regions of ocean ...

Volcano
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is str ...

Hekla
Hekla (), or Hecla, is an active stratovolcano in the south of Iceland with a height of . Hekla is one of Iceland's most active volcanoes; over 20 eruptions have occurred in and around the volcano since the year 1210. During the Middle Ages, the Icelandic Norse called the volcano the "Gateway to Hell" and the idea spread over much of Europe. The volcano's frequent large and often initially explosive eruptions have covered much of Iceland with tephra, and these layers can be used to date eruptions of Iceland's other volcanoes. Approximately 10% of the tephra created in Iceland in the last thousand years has come from Hekla, amounting to . Cumulatively, the volcano has produced one of the largest volumes of lava of any in the world in the last millennium, around . Etymology In Icelandic language, Icelandic ''Hekla'' is the word for a short hooded cloak, which may relate to the frequent cloud cover on the summit. An early Latin source refers to the mountain as ''Mons chasuble, Cas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
