Trollhättan Falls
Trollhättan Falls is a waterfall in the Göta river () 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 were 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 Vänern ( , , ) is the largest lake in Sweden, the largest lake in the European Union and the third-largest lake in Europe after Ladoga and Onega in Russia.

Trollhättan Falls 1888
Trollhättan () is the 23rd-largest city in Sweden, the seat of Trollhättan Municipality, Västra Götaland County. It is situated by Göta älv, near the lake Vänern, and has a population of approximately 50,000 in the city proper. It is located 75 km (46 mi) north of Sweden's second-largest city, Gothenburg. History Trollhättan was granted city rights (which today have no legal effect) in 1916 at which time it had about 15,000 inhabitants, now grown to 59,058. Trollhättan was founded on the river Göta älv, at the Trollhättan Falls. The site was first mentioned in literature from 1413. Trollhättan had a strategic significance on the road between Västergötland and Norway. It was also of a commercial and political significance for shipping to and from Vänern. Utilization of the river falls was the first important business activity in the area. From the Middle Ages milling and sawing operations have been conducted where the city center is now located.

Waterfall
A waterfall is any point in a river or stream where water flows over a vertical drop or a series of steep drops. Waterfalls also occur where meltwater drops over the edge of a tabular iceberg or ice shelf. Waterfalls can be formed in several ways, but the most common method of formation is that a river courses over a top layer of resistant bedrock before falling onto softer rock, which erodes faster, leading to an increasingly high fall. Waterfalls have been studied for their impact on species living in and around them. Humans have had a distinct relationship with waterfalls since prehistory, travelling to see them, exploring and naming them. They can present formidable barriers to navigation along rivers. Waterfalls are religious sites in many cultures. Since the 18th century, they have received increased attention as tourist destinations, sources of hydropower, andparticularly since the mid-20th centuryas subjects of research.

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. 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 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 ; 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 spans the width of Sweden to th ...

Vänern
Vänern ( , , ) is the largest lake in Sweden, the largest lake in the European Union and the third-largest lake in Europe after Ladoga and Onega in Russia. It is located in the provinces of Västergötland, Dalsland, and Värmland in the southwest of the country. With its surface located at above sea level and a maximum depth of , the lowest point of the Vänern basin is below sea level. The average depth is a more modest , which means that the lake floor is above sea level on average. Vänern drains into Göta älv towards Gothenburg and the Kattegat opening strait between the Atlantic Ocean’s North Sea and the Baltic Sea. It is the only one of the ten largest lakes in Sweden not to drain out to the eastern coastline. The Göta Canal built in the 19th century forms a waterway that runs to Vättern wholly rising when proceeding eastward, and then a navigable river linking the east coast with Vänern. The main inflow of water comes from Klarälven entering Vänern nea ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kattegat
The Kattegat (; ; ) is a sea area bounded by the peninsula of Jutland in the west, the Danish straits islands of Denmark and the Baltic Sea to the south and the Swedish provinces of Bohuslän, Västergötland, Halland and Scania in Sweden in the east. The Baltic Sea drains into the Kattegat through the Danish straits. The sea area is a continuation of the Skagerrak and may be seen as a bay of the North Sea and North Atlantic Ocean, though this is not the case in traditional Scandinavian usage. The Kattegat is a rather shallow sea and can be dangerous to navigate due to many sandy, stony reefs and the tricky shifting currents. In modern times, artificial seabed channels have been dug, many reefs have been dredged either by sand pumping or boulder clearance, and a well-developed light signaling network has been installed to protect the heavy international traffic on this small sea. There are several large cities and major ports on the Kattegat, including, in descendin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hojum Power Station
Hojum Power Station (alt. ''Håjum Power Station'') is the second hydroelectric power station in Trollhättan, the first one being the older Olidan Power Station. While the first two turbines were taken into service in 1938, a third one was built and started in 1992. The first two are rated at 50 MW, while the third is rated at 70 MW. The station is mainly located underground in a large mountain hall. This design was chosen because of the political instability in Europe at the time, which later led to the second world war. The relatively small building above ground was drawn by the Swedish architect An architect is a person who plans, designs, and oversees the construction of buildings.

Olidan
Olidan Power Station () is a hydroelectric power station located in Trollhättan, Sweden. First opened in 1910, it was the first large scale attempt at generating electricity from water in Sweden. The construction of Olidan led to the founding of the ''Kungliga Vattenfallsstyrelsen'' (Royal Waterfall Board), which later became Vattenfall. While the first four turbines were put into service in 1910, construction continued, and another four were put into operation by 1914. Due to increasing demand, as well as increasing capacity due to the regulation of Göta älv, another five were then built. By 1921, Olidan carried a total of 13 turbines. 10 of these are still functioning, while the other three were cannibalized for parts. However, it is currently rare for more than three to be generating at the one time. Each turbine has a capacity of 10 MW. When Olidan were completed in 1924, planning began for Hojum Power Station Hojum Power Station (alt. ''Håjum Power Station'') is the ...

Landforms Of Västra Götaland County
A landform is a land feature on the solid surface of the Earth or other planetary body. They may be natural or may be anthropogenic (caused or influenced by human activity). Landforms together make up a given terrain, and their arrangement in the landscape is known as topography. Landforms include hills, mountains, canyons, and valleys, as well as shoreline features such as bays, peninsulas, and seas, including submerged features such as mid-ocean ridges, volcanoes, and the great oceanic basins. Physical characteristics Landforms are categorized by characteristic physical attributes such as elevation, slope, orientation, structure stratification, rock exposure, and soil type. Gross physical features or landforms include intuitive elements such as berms, cliffs, hills, mounds, peninsulas, ridges, rivers, valleys, volcanoes, and numerous other structural and size-scaled (e.g. ponds vs. lakes, hills vs. mountains) elements including various kinds of inland and oceanic waterbodi ...
