Blanda
The Blanda () is a river in Iceland which flows northwards from the northwest side of the Hofsjökull glacier into Húnaflói bay at Blönduós. The Blanda is one of the longest rivers in the country, with a length of about 125 km, and has a catchment area estimated at 2370 km2. Its source is calculated to lie at a height of 800m. The river is one of the main salmon rivers in Iceland and has often yielded a catch of almost 3000 salmon in one summer. Before the river was dammed in 1990, the salmon spawning grounds reached almost to the foot of the glacier. Blanda hydroelectric 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 ... power station uses the drop of the river to generate up to 150 MW of power.

Blönduós
Blönduós () is a town and former municipality in the north of Iceland with a population of 895 in 2018. Like many towns and villages around Iceland, Blönduós did not emerge as a village until the late 19th century. The town is situated on Route 1 at the mouth of the glacial river Blanda. Hrútey , a small island and natural reserve encircled by the river, is accessible via a pedestrian bridge just off the ring road. In 2022, the town merged with Húnavatnshreppur to form Húnabyggð. Geography One of Blönduós' main characteristics is that the town is split into two parts by the glacial river Blanda, for which it is named (Blöndu is an oblique case of Blanda). The old part of town ( Icelandic: "gamli bærinn"), including many original houses from the late 19th and early 20th century, is located on the south side of the river. Many of the local companies, the elementary school, supermarket, community center and sports facilities including a modern outdoor heated pool are ...

Iceland
Iceland ( is, Ísland; ) is a Nordic island country in the North Atlantic Ocean and in the Arctic Ocean. Iceland is the most sparsely populated country in Europe. Iceland's capital and largest city is Reykjavík, which (along with its surrounding areas) is home to over 65% of the population. Iceland is the biggest part of the Mid-Atlantic Ridge that rises above sea level, and its central volcanic plateau is erupting almost constantly. The interior consists of a plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a high latitude just outside the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. According to the ancient manuscript , the settlement of Iceland began in 874 AD when the Norwegian chieftain Ingólfr Arnarson became the first p ...

Hofsjökull
__NOTOC__ Hofsjökull ( Icelandic: "temple glacier", ) is the third largest ice cap in Iceland after Vatnajökull and Langjökull and the largest active volcano in the country. It is situated in the west of the Highlands of Iceland and north of the mountain range Kerlingarfjöll, between the two largest glaciers of Iceland. It covers an area of 925 km2, reaching at its summit. The subglacial volcano is a shield type with caldera. Hofsjökull is the source of several rivers including the Þjórsá, Iceland's longest river. In the southeast of Iceland, between the easternmost glacier tongue of Vatnajökull (Axajökull) and Þrándarjökull, there is a smaller glacier (area about 4 km2), which is also called Hofsjökull. In 2015, Hofsjökull increased in mass, the first time in 20 years this had happened.

Húnaflói
Húnaflói (, "Huna Bay") is a large bay between Strandir and Skagaströnd in Iceland. It is about wide and long. The towns Blönduós and Skagaströnd are located on the bay's eastern side. Fauna The bay has been proposed as a protected area for harbor seal The harbor (or harbour) seal (''Phoca vitulina''), also known as the common seal, is a true seal found along temperate and Arctic marine coastlines of the Northern Hemisphere.

Drainage Basin
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the '' drainage divide'', made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern. Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, and impluvium. In North America, they are commonly called a watershed, though in other English-speaking places, "watershed" is used only in its original sense, that of a drainage divide. In a closed drainage basin, or endorheic basin, the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, a dry lake, or a point where surface water is lost underground. Drainage basins are similar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

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.

Watt
The watt (symbol: W) is the unit of power or radiant flux in the International System of Units (SI), equal to 1 joule per second or 1 kg⋅m2⋅s−3. It is used to quantify the rate of energy transfer. The watt is named after James Watt (1736–1819), an 18th-century Scottish inventor, mechanical engineer, and chemist who improved the Newcomen engine with his own steam engine in 1776. Watt's invention was fundamental for the Industrial Revolution. Overview When an object's velocity is held constant at one metre per second against a constant opposing force of one newton, the rate at which work is done is one watt. : \mathrm In terms of electromagnetism, one watt is the rate at which electrical work is performed when a current of one ampere (A) flows across an electrical potential difference of one volt (V), meaning the watt is equivalent to the volt-ampere (the latter unit, however, is used for a different quantity from the real power of an electrical circuit). : ...
