Dalälven Basin
The Dal River () is a river in central Sweden that flows from the north of Dalarna and runs into the sea in northern Uppland; it is commonly considered to be the southern border of Norrland, however only the last part correlates with Limes Norrlandicus (the biological Norrland border). The northern part is split into two rivers: Österdalälven (East Dal) and Västerdalälven (West Dal). The two connect in Djurås. It is over long — the second longest river in Sweden, and has a hydropower potential of 1420 megawatts, of which 2/3 is utilized. The largest power plant is located at the Trängslet Dam. Dalälven has been significant historically as a raft transport route. Nedre Dalälven River Landscape, Sweden, covers with a mixture of wetlands, rivers, lakes, flood plains and productive forests. It includes Lake Hovran and Färnebofjärden Bay Ramsar site. The region boasts high biodiversity, as the river forms a clear border zone between the northern and southern flora ...

Avesta (locality)
Avesta () is a locality and the seat of Avesta Municipality in Dalarna County, Sweden, with 11,949 inhabitants in 2015. The name of Avesta is first found in 1303 as "Aghastadhum".

The present name of the town is identical with that of the ancient Persian language and scriptures, but there is no apparent linguistic connection between them. History In the Scandinavian Middle Ages there was a blast furnace at the location. In 1636 the construction of a giant copper mine was initiated near the Avesta fors. The town Avesta received partial privileges in 1641 as a town under the city of Falun, and in 1644 a copper mint was built. However, the privileges were withdrawn in 1688 due to complaints of competition from its neighbour, mainl ... [...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 electricity generation, generation of electric power. Power stations are generally connected to an electrical grid. Many power stations contain one or more Electric generator, generators, rotating machine that converts mechanical power into three-phase electric power. The relative motion between a magnetic field and a Electrical conductor, 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, petroleum, oil, and natural gas to generate electricity. Low-carbon power sources include nuclear power, and use of renewable energy, renewables such as solar power, solar, wind power, wind, geothermal power, geothermal, and hydroelectricity, hydroelectric. History In early 1871 Belgian inventor Zénobe Gramme invented a generator powerfu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Impact Crater
An impact crater is a depression (geology), depression in the surface of a solid astronomical body formed by the hypervelocity impact event, impact of a smaller object. In contrast to volcanic craters, which result from explosion or internal collapse, impact craters typically have raised rims and floors that are lower in elevation than the surrounding terrain. Impact craters are typically circular, though they can be elliptical in shape or even irregular due to events such as landslides. Impact craters range in size from microscopic craters seen on lunar rocks returned by the Apollo Program to simple bowl-shaped depressions and vast, complex, multi-ringed impact basins. Meteor Crater is a well-known example of a small impact crater on Earth. Impact craters are the dominant geographic features on many solid Solar System objects including the Moon, Mercury (planet), Mercury, Callisto (moon), Callisto, Ganymede (moon), Ganymede, and most small moons and asteroids. On other planet ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Siljan
Siljan, in Dalarna in central Sweden, is Sweden's seventh largest lake. The cumulative area of Siljan and the adjacent, smaller lakes Orsasjön and Insjön is . Siljan reaches a maximum depth of , and its surface is situated above sea level. This renders the lowest point of the basin at above sea level. The largest town on its shore is Mora. Impact crater The lake is located around the southwestern perimeter of the Siljan Ring (Swedish: ''Siljansringen''), a circular geological formation which was formed 377 million years ago in the Devonian by a major meteorite impact. The original crater, now mostly eroded, is estimated to have been about 52 km (32 mi) in diameter and is the largest known impact crater in Europe (excluding Russia). The Cambrian, Ordovician and Silurian sedimentary rocks deformed by the impact are rich in fossils. Some people suspect that there might be oil in the area, but drilling has been unsuccessful so far. There are large deposits of lead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Göta älv
The (; "River of (the) Geats") is a river that drains lake Vänern into the Kattegat, at the city of Gothenburg, on the western coast of Sweden.

Environmental Monitoring
Environmental monitoring is the processes and activities that are done to characterize and describe the state of the environment. It is used in the preparation of environmental impact assessments, and in many circumstances in which human activities may cause harmful effects on the natural environment. Monitoring strategies and programmes are generally designed to establish the current status of an environment or to establish a baseline and trends in environmental parameters. The results of monitoring are usually reviewed, analyzed statistics, statistically, and published. A monitoring programme is designed around the intended use of the data before monitoring starts. Environmental monitoring includes monitoring of Air pollution, air quality, soils and water quality. Many monitoring programmes are designed to not only establish the current state of the environment but also predict future conditions. In some cases this may involve collecting data related to events in the distant p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
