Göta älv
The Göta älv (; "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. It was formed at the end of the last glaciation, as an outflow channel from the Baltic Ice Lake to the Atlantic Ocean and nowadays it has the largest drainage basin in Scandinavia. The Göta älv is located in Götaland, with the river itself being a site of early Geatish settlement. Its length is . The Bohus Fortress is located by the river at Kungälv. There the river splits into two, with the northern part being the Nordre älv and the southern part keeping the name Göta älv; the two arms of the river enclose the island of Hisingen. At Trollhättan there is a dam, canal locks and a hydropower station in the river. The locks make the river navigable, even for large cargo vessels ( long). The artificial parts are called Trollhätte Canal. The river and the canal is part of a mostly inland waterway, Göta Canal, which spa ...

Trollhättan Falls
Trollhättan Falls is a waterfall in the Göta river (Göta älv) in Sweden. The falls starts at Malgö Bridge in central Trollhättan, and has a total height of 32 metres, making up a large part of the 44 metre total fall of the river from Vänern to Kattegat. Before the hydroelectric powerplants was built the discharge of the falls was 900 m³/s, and the falls stretched down to Olidehålan, where the lower part of the fall was called ''Helvetesfallet'' ("Hell Falls"). Today the river is allowed through its original course only at special occasions, to regulate the waterlevels of Vänern or as a tourist attraction, such as during the ''Fallens dagar'' ("Days of the Waterfalls"), arranged on the third Friday of July every year. The discharge is then 300 m³/s. Most of the time the falls are used in the hydroelectric powerplants Håjum and Olidan Olidan Power Station ( sv, Olidans kraftverk) is a hydroelectric power station located in Trollhättan, Sweden.

Kungälv
Kungälv () (old no, Konghelle) is a city and the seat of Kungälv Municipality in Västra Götaland County, Sweden. It had 22,768 inhabitants in 2010. In 2021, the main Kungälv - Ytterby - Kareby conurbation had a combined population approaching 30,000. In total, the whole municipality had 47,050 inhabitants. History According to official Swedish sources the city was founded in 1612, when the city of Konghelle was moved closer to the Bohus Fortress. However, this is disputed because other sources indicate that it was just a strategic relocation of the existing Norwegian city, the capital of Norway at one point under Sigurd I Magnusson, something frequently used for marketing and tourist purposes. For this reason, Kungälv could celebrate its "1000-year anniversary" in 1959. Sigurd I Magnusson (''Sigurd Jorsalfare'', i.e., Sigurd the Crusader) was the King of Norway (1103–1130) and is the best-known crusader king of Scandinavia. He was also the first European king to join ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tuve Landslide
The Tuve landslide was a large landslide in Tuve, Gothenburg, Sweden on November 30, 1977. Some 67 houses were destroyed, killing 9, injuring about 60 and making around 600 people homeless. The slide began at 16.05 and lasted 5–6 minutes. The slide affected 270 000 square meters (27 hectares). About 600 people lived in the area; of these, approximately 200 were in the area at the time of the slide. About 100 needed help by rescue workers. It was the most severe landslide in the modern history of Sweden. Close to one kilometer of the nearby road was destroyed. It is estimated that three to four million cubic meters of soil were involved in the slide and further would not have fertility to grow crops. The total economic cost of the slide has been estimated to 140 million SEK (15 million EUR, 22 million USD). Cause The slide was caused by heavy rain and an unstable slope. Aftermath After the slide it was concluded that many areas were built without a proper prior geotechnica ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tourist
Tourism is travel for pleasure or business; also the theory and practice of touring, the business of attracting, accommodating, and entertaining tourists, and the business of operating tours. The World Tourism Organization defines tourism more generally, in terms which go "beyond the common perception of tourism as being limited to holiday activity only", as people "travelling to and staying in places outside their usual environment for not more than one consecutive year for leisure and not less than 24 hours, business and other purposes". Tourism can be domestic (within the traveller's own country) or international, and international tourism has both incoming and outgoing implications on a country's balance of payments. Tourism numbers declined as a result of a strong economic slowdown (the late-2000s recession) between the second half of 2008 and the end of 2009, and in consequence of the outbreak of the 2009 H1N1 influenza virus, but slowly recovered until the COVID-19 ...

Industrial Revolution
The Industrial Revolution was the transition to new manufacturing processes in Great Britain, continental Europe, and the United States, that occurred during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines, new chemical manufacturing and iron production processes, the increasing use of steam power and water power, the development of machine tools and the rise of the mechanized factory system. Output greatly increased, and a result was an unprecedented rise in population and in the rate of population growth. Textiles were the dominant industry of the Industrial Revolution in terms of employment, value of output and capital invested. The textile industry was also the first to use modern production methods. The Industrial Revolution began in Great Britain, and many of the technological and architectural innovations were of British origin. By the mid-18th century, Britain was the world's leadi ...

Steel Industry
Steel is an alloy made up of iron with added carbon to improve its strength and fracture resistance compared to other forms of iron. Many other elements may be present or added. Stainless steels that are corrosion- and oxidation-resistant typically need an additional 11% chromium. Because of its high tensile strength and low cost, steel is used in buildings, infrastructure, tools, ships, trains, cars, machines, electrical appliances, weapons, and rockets. Iron is the base metal of steel. Depending on the temperature, it can take two crystalline forms (allotropic forms): body-centred cubic and face-centred cubic. The interaction of the allotropes of iron with the alloying elements, primarily carbon, gives steel and cast iron their range of unique properties. In pure iron, the crystal structure has relatively little resistance to the iron atoms slipping past one another, and so pure iron is quite ductile, or soft and easily formed. In steel, small amounts of carbon, other ele ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Baltic Sea
The Baltic Sea is an arm of the Atlantic Ocean that is enclosed by Denmark, Estonia, Finland, Germany, Latvia, Lithuania, Poland, Russia, Sweden and the North and Central European Plain. The sea stretches from 53°N to 66°N latitude and from 10°E to 30°E longitude. A marginal sea of the Atlantic, with limited water exchange between the two water bodies, the Baltic Sea drains through the Danish Straits into the Kattegat by way of the Øresund, Great Belt and Little Belt. It includes the Gulf of Bothnia, the Bay of Bothnia, the Gulf of Finland, the Gulf of Riga and the Bay of Gdańsk. The " Baltic Proper" is bordered on its northern edge, at latitude 60°N, by Åland and the Gulf of Bothnia, on its northeastern edge by the Gulf of Finland, on its eastern edge by the Gulf of Riga, and in the west by the Swedish part of the southern Scandinavian Peninsula. The Baltic Sea is connected by artificial waterways to the White Sea via the White Sea–Baltic Canal and to the German ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Göta Canal
The Göta Canal ( sv, Göta kanal) is a Swedish canal constructed in the early 19th century. The canal is long, of which were dug or blasted, with a width varying between and a maximum depth of about .Uno Svedin, Britt Hägerhäll Aniansson, ''Sustainability, Local Democracy and the Future: The Swedish Model'', pp. 93–94. Springer, 2002. The speed is limited to 5 knots in the canal. The Göta Canal is a part of a waterway long, linking a number of lakes and rivers to provide a route from Gothenburg (Göteborg) on the west coast to Söderköping on the Baltic Sea via the Trollhätte kanal and Göta älv river, through the large lakes Vänern and Vättern. This waterway was dubbed as Sweden's Blue Ribbon ( sv, Sveriges blå band). Contrary to the popular belief it is not correct to consider this waterway as a sort of ''greater'' Göta Canal: the Trollhätte Canal and the Göta Canal are completely separate entities.

Hydropower
Hydropower (from el, ὕδωρ, "water"), also known as water power, is the use of falling or fast-running water to Electricity generation, produce electricity or to power machines. This is achieved by energy transformation, converting the Potential energy, gravitational potential or kinetic energy of a water source to produce power. Hydropower is a method of sustainable energy production. Hydropower is now used principally for Hydroelectricity, hydroelectric power generation, and is also applied as one half of an energy storage system known as pumped-storage hydroelectricity. Hydropower is an attractive alternative to fossil fuels as it does not directly produce Carbon dioxide in Earth's atmosphere, carbon dioxide or other Air pollution, atmospheric pollutants and it provides a relatively consistent source of power. Nonetheless, it has economic, sociological, and environmental downsides and requires a sufficiently energetic source of water, such as a river or elevated lake. Int ...
