Nidau-Büren Canal
The Nidau-Büren Canal (german: Nidau-Büren-Kanal, french: Canal de Nidau-Büren) is a -long canal that drains the waters of the river Aare out of the Lake of Biel/Bienne toward Solothurn. It was dug as an important part of the first Jura water correction. Regulating dam A temporary dam had been built across the Nidau-Büren channel, in order to maintain the water level in the lake. Of insufficient retaining capacity, another one was erected in 1887 that also showed its limits, especially during a flood in 1910. Soon, the cantons of Vaud, Neuchâtel and Fribourg required its replacement, but it was only modified in 1911 and 1915. Finally, the building of the new regulating dam was started in Port in 1936, and it was completed and commissioned in 1939 and has been daily in use ever since. The dam includes a lock that is large enough for tour boats that run between Biel and Solothurn. In 1995 a hydroelectric plant was added to the lock. This plant, located near Brügg produ ...

Aare
The Aare () or Aar () is a tributary of the High Rhine and the longest river that both rises and ends entirely within Switzerland. Its total length from its source to its junction with the Rhine comprises about , during which distance it descends , draining an area of , almost entirely within Switzerland, and accounting for close to half the area of the country, including all of Central Switzerland. There are more than 40 hydroelectric plants along the course of the Aare. The river's name dates to at least the La Tène period, and it is attested as ''Nantaror'' "Aare valley" in the Berne zinc tablet. The name was Latinized as ''Arula''/''Arola''/''Araris''. Course The Aare rises in the great Aargletschers (Aare Glaciers) of the Bernese Alps, in the canton of Bern and west of the Grimsel Pass. The Finsteraargletscher and Lauteraargletscher come together to form the Unteraargletscher (Lower Aar Glacier), which is the main source of water for the Grimselsee (Lake of ...

Lock (water Transport)
A lock is a device used for raising and lowering boats, ships and other watercraft between stretches of water of different levels on river and canal waterways. The distinguishing feature of a lock is a fixed chamber in which the water level can be varied; whereas in a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson) that rises and falls. Locks are used to make a river more easily navigable, or to allow a canal to cross land that is not level. Later canals used more and larger locks to allow a more direct route to be taken. Pound lock A ''pound lock'' is most commonly used on canals and rivers today. A pound lock has a chamber with gates at both ends that control the level of water in the pound. In contrast, an earlier design with a single gate was known as a flash lock. Pound locks were first used in China during the Song Dynasty (960–1279 AD), having been pioneered by the Song politician and n ...

Water Transport In Switzerland
Switzerland has a dense network of roads and railways. The Swiss public transport, public transport network has a total length of 24,500 kilometers and has more than 2600 stations and stops. The crossing of the Alps is an important route for European transportation, as the Alps separate Northern Europe from Southern Europe. Alpine railway routes began in 1882 with the Gotthard Railway with its central Gotthard Rail Tunnel, followed in 1906 by the Simplon Tunnel and the Lötschberg Tunnel in 1913. As part of the NRLA, New Railway Link through the Alps (NRLA) in 2007 the Lötschberg Base Tunnel opened and in 2016 the Gotthard Base Tunnel opened on 1 June. The Swiss road network is funded by road pricing, road tolls and vehicle taxes. The Swiss motorway system requires the purchase of a Vignette (road tax)#Switzerland, road tax disc - which costs 40 Swiss francs for one calendar year - in order to use its roadways, for both passenger cars and trucks. The Swiss motorway network has ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Canals In Switzerland
Canals or artificial waterways are waterways or engineered channels built for drainage management (e.g. flood control and irrigation) or for conveyancing water transport vehicles (e.g. water taxi). They carry free, calm surface flow under atmospheric pressure, and can be thought of as artificial rivers. In most cases, a canal has a series of dams and locks that create reservoirs of low speed current flow. These reservoirs are referred to as ''slack water levels'', often just called ''levels''. A canal can be called a ''navigation canal'' when it parallels a natural river and shares part of the latter's discharges and drainage basin, and leverages its resources by building dams and locks to increase and lengthen its stretches of slack water levels while staying in its valley. A canal can cut across a drainage divide atop a ridge, generally requiring an external water source above the highest elevation. The best-known example of such a canal is the Panama Canal. Many ...

Kilowatt-hours
A kilowatt-hour ( unit symbol: kW⋅h or kW h; commonly written as kWh) is a unit of energy: one kilowatt of power for one hour. In terms of SI derived units with special names, it equals 3.6 megajoules (MJ). Kilowatt-hours are a common billing unit for electrical energy delivered to consumers by electric utilities. Definition The kilowatt-hour is a composite unit of energy equal to one kilowatt (kW) sustained for (multiplied by) one hour. Expressed in the standard unit of energy in the International System of Units (SI), the joule (symbol J), it is equal to 3,600 kilojoules or 3.6 MJ."Half-high dots or spaces are used to express a derived unit formed from two or more other units by multiplication.", Barry N. Taylor. (2001 ed.''The International System of Units.'' (Special publication 330). Gaithersburg, MD: National Institute of Standards and Technology. 20.

Hydroelectricity
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 also more than nuclear power. Hydropower can provide large amounts of 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.

Port, Switzerland
Port is a municipality in the canton of Bern in Switzerland, located in the Biel/Bienne administrative district. History Port is first mentioned in 1228 as ''Port''. The banks of the Zihl/Thielle river were inhabited since at least the neolithic. The remains of a neolithic Cortaillod culture stilt house village from the second quarter of the 4th Millennium BC were discovered in the Stüdeli area. The area was resettled often during the following millennia. From Bronze Age settlements a number of artifacts were discovered including swords, spearheads, axes and sickles. A Celtic settlement from the 2nd and 1st centuries BC left behind two helmets, metal vessels and about 120 swords and spearheads. However, most of the swords were broken or bent. One bent iron sword contains an engraving, in Greek letters, of the name Korisios. This is considered the oldest written document in Switzerland. Wooden pilings from the same era indicate that the settlement built a bridge ove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Of Bienne
__NOTOC__ Lake Bienne or Lake Biel (french: Lac de Bienne ; german: Bielersee) is a lake in western Switzerland. Together with Lake Morat and Lake Neuchâtel, it is one of the three large lakes in the Jura region of Switzerland. It lies approximately at the language boundary between German and French speaking areas. Geography The lake is 15 km long and up to 4.1 km wide. Its surface area is 39.3 km², the maximum depth 74 m. The lake is located at 429 metres above sea level. Lake Biel/Bienne has a catchment area of about 8,305 km². Water remains in the lake for an average of 58 days. The rivers Aare and Zihl/Thielle flowing from Lake Neuchâtel, the Twannbach draining water down from the surplombing first Jura mountain range and the Suze draining water down from the Vallon de St. Imier, are the main tributaries. The Aare was redirected into the lake in 1878, in order to prevent the flooding of the nearby area called "Seeland", and drains the water out of the la ...

Regulating Dam Port, Seeland, Switzerland
500px, Map of the area following the construction of the canal During the first Jura water correction, a temporary dam had been built across the Nidau-Büren channel in order to maintain the water level in Lake Bienne. Of insufficient retaining capacity, another one in 1887 that also showed its limits, especially during a flood in 1910, quickly replaced it. Soon, the cantons of Vaud, Neuchâtel and Fribourg required its replacement, but it was only modified in 1911 and 1915. Finally, the building of the new regulating dam was started in Port in 1936, and completed and commissioned in 1939. This dam ensures the level control of the three lakes of Neuchâtel, Morat and Bienne, an area so called the " Seeland”,as well as the outflow of the Aare river downstream toward Solothurn, Aargau and the junction with Emme River down to the merging with the Rhine River. The three lakes act as a buffer zone, absorbing waters of the Aare in the event of any upstream flooding as far as the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
