Väddö Canal
The Väddö Canal () is an artificial canal first dug in the 16th century to provide a sheltered passage between the to the south and the to the north. The canal separates the island of Väddö from the mainland, and passes through the village of Älmsta at its northern end, and the lake of Storfjärden towards its middle. The canal has an official depth of 2.0 metres and is mainly used by leisure boats, with some 20,000 boats passing through every year. There are no Lock (water navigation), locks, but there are two opening bridges, the ''Älmstabron'' and the ''Bagghusbron''. The canal is routed along, or close to, what was originally a natural waterway, but this ceased to be navigable in the Middle Ages. A new channel was dredged several times, the first time to the order of Gustav Vasa, King Gustav I in the 16th century. By the 18th century, the waterway had again ceased to be navigable, and the current canal was dug by the Swedish Army between 1820 and 1840, with traffic usi ...

Sjöfartsverket
The Swedish Maritime Administration () is the Government agencies in Sweden, government agency in Sweden which provides services to the transport sector by keeping the sea lanes open and safe. The agency is to a certain degree financed through fees levied on commercial shipping. The main services of the Maritime Administration include: pilotage, maintenance of marine Fairway (navigation), fairways, ice-breaking, Hydrographic survey, hydrographics, maritime search and rescue, seamen's service. It also maintains the lighthouses and other aids to navigation of Sweden. Until 1 January 2009, it also was responsible for maritime safety inspection. Seagoing vessels navigating the Baltic Sea must meet certain ice class requirement. While its mainly deals with merchant shipping, other maritime activities are also taken into account. Sjöfartsverket runs the Joint Rescue Center Gothenburg. See also * List of lighthouses and lightvessels in Sweden * P2 – Svenskt Vrakskydd * Sea traffic m ...

Älmsta
Älmsta or Elmsta is a locality situated in Norrtälje Municipality, Stockholm County, Sweden. It had 924 inhabitants in 2005 and 1,097 in 2010. Elmsta is the old Swedish name, which has become more popular again (e.g. names of stores), while Älmsta still is the official name. Älmsta is situated at the northern end of the Väddö Canal, an artificial canal first dug in the 16th century to provide a sheltered passage between the to the south and the to the north. The canal has been rebuilt on several occasions since and is still used by some 22,000 boats annually. Part of Älmsta lies on the island of Väddö Väddö is an island in the Baltic Sea in Roslagen district, Sweden. It is situated in Norrtälje Municipality.

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] |
Opening Bridge
A moveable bridge, or movable bridge, is a bridge that moves to allow passage for boats or barges. In American English, the term is synonymous with , and the latter is the common term, but drawbridge can be limited to the narrower, historical definition used in some other forms of English, in which ''drawbridge'' refers to only a specific type of moveable bridge often found in castles. An advantage of making bridges moveable is the lower cost, due to the absence of high piers and long approaches. The principal disadvantage is that the traffic on the bridge must be halted when it is opened for passage of traffic on the waterway. For seldom-used railroad bridges over busy channels, the bridge may be left open and then closed for train passages. For small bridges, bridge movement may be enabled without the need for an engine. Some bridges are operated by the users, especially those with a boat, others by a bridgeman (or bridge tender); a few are remotely controlled using video-c ...

Middle Ages
In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, similarly to the post-classical period of global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the Middle East—once part of the Byzantine Empireâ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gustav Vasa
Gustav Eriksson Vasa (12 May 1496 – 29 September 1560), also known as Gustav I, was King of Sweden from 1523 until his death in 1560. He was previously self-recognised Protector of the Realm (''Reichsverweser#Sweden, Riksföreståndare'') from 1521, during the ongoing Swedish War of Liberation against King Christian II of Denmark, Norway and Sweden. Gustav rose to lead the Swedish War of Liberation following the Stockholm Bloodbath, where his father was executed. Gustav's election as king on 6 June 1523 (the National Day of Sweden) and his triumphant Conquest of Stockholm, entry into Stockholm eleven days later marked Sweden's final secession from the Kalmar Union. During his reign, Gustav initiated the Protestant reformation in Sweden, transformed the country from an elective monarchy, elective to a hereditary monarchy and established a standing Swedish Army, army and Swedish Navy, navy.

Canals In Sweden
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.
