Elbląg Canal
Elbląg Canal (; ) is a canal in Poland, in Warmian-Masurian Voivodeship, in length, which runs southward from Drużno, Lake Drużno (connected by the river Elbląg (river), Elbląg to the Vistula Lagoon), to the river Drwęca and lake Jeziorak. It can accommodate small vessels up to displacement. The difference in water levels approaches , and is overcome using locks and a system of Canal inclined plane, inclined planes between lakes. Today it is used mainly for recreational purposes. It is considered one of the most significant monuments related to the history of technology and was named one of the Seven Wonders of Poland. As per results of a plebiscite for th'Seven Wonders of Poland'conducted by Rzeczpospolita (newspaper), cited at www.budowle.pl. The canal was also named one of Poland's official national List of Historic Monuments (Poland), Historic Monuments (''Pomnik historii''), as designated January 28, 2011. Its listing is maintained by the National Heritage Board of P ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lock (water Navigation)
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 chamber in a permanently fixed position in which the water level can be varied. (In a caisson lock, a boat lift, or on a canal inclined plane, it is the chamber itself (usually then called a caisson (engineering), 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. Over time, more and larger locks have been used in canals to allow a more direct route to be taken. History Ancient Egypt In Ancient Egypt, the river-locks was probably part of the Canal of the Pharaohs: Ptolemy II is credited by some for being the first to solve the problem of keeping the Nile free of salt water when his engineers invented the lock around 274/273 BC. Ancient China During 960–1279 CE, the natural extension o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ship Lift Of Krasnoyarsk Hydroelectric Power Station
The Krasnoyarsk ship lift (Russian: ) is a boat lift at the Krasnoyarsk hydroelectric power station on the Yenisei River, located in Divnogorsk, Russia. It is the only boat lift in Russia. The Krasnoyarsk ship lift was developed by Lenhydroproject, and manufactured by Lengidrostal. Construction began in 1976, and the lift was operational by 1982. The boat lift consists of the outer harbor, the bottom of the approach channel, the lift itself, and a turntable. The platform of the lift moves along an inclined rack railway with a track gauge of 9 m. The lift is propelled by an electric drive. Ships transported by the Krasnoyarsk ship lift remain afloat. The lift platform contains a caisson, so that boats may simply float into the platform when they wish to traverse the dam. In order to load the ship lift, the platform is partially lowered below the water level and a gate opens. A ship may then float onto the platform, at which point the gate is closed behind the ship, sealing t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Ruda Woda
Lake Ruda Woda (; ) is a long freshwater ribbon lake in Powiśle (region), Powiśle region in northern Poland. The lake lies entirely within Gmina Małdyty in Warmian-Masurian Voivodeship and is an integral part of the Elbląg Canal. Stretching in length, the lake features four distinct bays and several islands. The lakebed is diverse, with numerous depressions and shallows. Shores are mostly high and steep, surrounded by temperate deciduous forest, with only the southern and northern parts bordered by fields and meadows. Lake’s surroundings are sparsely populated with several villages located nearby, including Wilamowo, Ostróda County, Wilamowo, Szymonowo, Szymonówko, Sople, Warmian-Masurian Voivodeship, Sople and Liksajny. The lake provides fishing and recreation opportunities, including sailing, kayaking and jet skiing.

Boat Lift
A boat lift, ship lift, or lift lock is a machine for transporting boats between water at two different elevations, and is an alternative to the canal lock. It may be vertically moving, like the Anderton boat lift in England, rotational, like the Falkirk Wheel in Scotland, or operate on an inclined plane, like the Ronquières inclined plane in Belgium. History A precursor to the canal boat lift, able to move full-sized canal boats, was the tub boat lift used in mining, able to raise and lower the 2.5 ton tub boats then in use. An experimental system was in use on the Churprinz mining canal in Halsbrücke near Dresden. It lifted boats using a moveable hoist rather than caissons. The lift operated between 1789 and 1868,Charles Hadfield ''World Canals: Inland Navigation Past and Present'', p. 71, and for a period of time after its opening engineer James Green reporting that five had been built between 1796 and 1830. He credited the invention to Dr James Anderson of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Caisson (engineering)
In geotechnical engineering, a caisson (; borrowed , , an augmentative of ) is a watertight retaining structure. It is used, for example, to work on the foundation (architecture), foundations of a bridge pier (architecture), pier, for the construction of a concrete dam, or for the repair of ships. Caissons are constructed in such a way that the water can be pumped out, keeping the work environment dry. When piers are being built using an open caisson, and it is not practical to reach suitable soil, Deep foundation, friction pilings may be driven to form a suitable sub-foundation. These piles are connected by a foundation pad upon which the column pier is erected. Caisson engineering has been used since at least the 19th century, with three prominent examples being the Royal Albert Bridge (completed in 1859), the Eads Bridge (completed in 1874), and the Brooklyn Bridge (completed in 1883). Types To install a caisson in place, it is brought down through soft mud until a suitable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Big Chute Marine Railway
Big Chute Marine Railway is a patent slip at lock 44 (in the township of Georgian Bay, Ontario, Georgian Bay) of the Trent-Severn Waterway in Ontario, Canada. It works on an inclined plane to carry boats in individual cradles over a change of height of about . It is the only marine railway (or canal inclined plane) of its kind in North America still in use, and is overseen by federally operated Parks Canada. This railway is vital for those cruising the Great Loop route. History In 1914, contracts were let to have 3 locks built to connect the Severn River to Georgian Bay at Port Severn, Big Chute, and Swift Rapids. With the start of World War I, however, there was a shortage of manpower and resources. Lock 45 at Port Severn was nearing completion, so it was finished as a small, "temporary" lock. (It remains in use to this day.) The locks at Big Chute and Swift Rapids were not completed, with "temporary" marine railways being built instead. The original Big Chute Marine Rai ...

Neman
Neman, Nemunas or Niemen is a river in Europe that rises in central Belarus and flows through Lithuania then forms Lithuania–Russia border, the northern border of Kaliningrad Oblast, Russia's western exclave, which specifically follows its southern channel. It drains into the Curonian Lagoon, narrowly connected to the Baltic Sea. The long Neman is a major Eastern European river. It flows generally west to Grodno within of the Polish border, north to Kaunas, then westward again to the sea. The largest river in Lithuania, and the third-largest in Belarus, it is navigable for most of its length. It starts from two small headwaters merging about southwest of the town of Uzda – about southwest of capital city Minsk. Only , an eastward meander, contributes to the Belarus–Lithuania border. Thereafter the river includes notable loops along a minor tectonic fault. Its drainage basin settled in the late Quaternary to be roughly along the edge of the last glacial sheet so d ...

Vistula
The Vistula (; ) is the longest river in Poland and the ninth-longest in Europe, at in length. Its drainage basin, extending into three other countries apart from Poland, covers , of which is in Poland. The Vistula rises at Barania Góra in the south of Poland, above sea level in the Silesian Beskids (western part of Carpathian Mountains), where it begins with the White Little Vistula (''Biała Wisełka'') and the Black Little Vistula (''Czarna Wisełka''). It flows through Poland's largest cities, including Kraków, Sandomierz, Warsaw, Płock, Włocławek, Toruń, Bydgoszcz, Świecie, Grudziądz, Tczew and Gdańsk. It empties into the Vistula Lagoon (''Zalew Wiślany'') or directly into the Gdańsk Bay of the Baltic Sea with a river delta, delta of six main branches (Leniwka, Przekop, Śmiała Wisła, Martwa Wisła, Nogat and Szkarpawa). The river has many associations with culture of Poland, Polish culture, history and national identity. It is Poland's most important wat ...

Augustów Canal
The Augustów Canal (, , ) is a cross-border canal built by the Congress Kingdom of Poland in 19th century in the Augustów Voivodeship (present-day Podlaskie Voivodeship of northeastern Poland and Grodno Region, Grodno Oblast of western Belarus). From the time it was first built, the canal was described by experts as a technological marvel, with numerous sluices contributing to its aesthetic appeal. It was the first summit level canal in Central Europe to provide a direct link between the two major rivers, Vistula River through the Biebrza River – a tributary of the Narew, Narew River, and the Neman River through its tributary – the Czarna Hańcza, Czarna Hańcza River, and it provided a link with the Black Sea to the south through the Oginski Canal, Daugava River, Berezina River, Berezina Canal and Dnieper River. It uses a post-glacial channel depression, forming the chain of Augustów lakes, and the river valleys of the Biebrza, the Netta, the Czarna Hańcza and ...

1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
