River Vuoksi
The Vuoksi (russian: Вуокса, historically: "Uzerva"; fi, Vuoksi; sv, Vuoksen) is a river running through the northernmost part of the Karelian Isthmus from Lake Saimaa in southeastern Finland to Lake Ladoga in northwestern Russia. The river enters Lake Ladoga in three branches, an older main northern branch at Priozersk (Käkisalmi), a smaller branch a few kilometers to the north of it, and a new southern branch entering further southeast as Burnaya River (Finnish: Taipaleenjoki), which has become the main stream in terms of water discharge. Since 1857, the old northern distributaries drain only the lower reaches of the Vuoksi basin and are not fed by Lake Saimaa. The northern and southern branches actually belong to two separate river systems, which at times get isolated from each other in dry seasons. The descent between Lake Saimaa and Lake Ladoga is . The entire run of the river is via the Priozersk branch, or via the Taipale (Burnaya) branch. It has a drainage ba ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lake Saimaa
Saimaa ( , ; sv, Saimen) is a lake located in the Finnish Lakeland area in southeastern Finland. At approximately , it is the largest lake in Finland, and the fourth largest natural freshwater lake in Europe. The name Saimaa likely comes from a non-Uralic, non-Indo European substrate language. History It was formed by glacial melting at the end of the Ice Age. Major towns on the lakeshore include Lappeenranta, Imatra, Savonlinna, Mikkeli, Varkaus, and Joensuu. About 6000 years ago, ancient Lake Saimaa, estimated to cover nearly at the time, was abruptly discharged through a new outlet. The event created thousands of square kilometres of new residual wetlands. Following this event, the region saw a population maximum in the decades following only to later return to an ecological development towards old boreal conifer forests which saw a decline in population. Topography The Vuoksi River flows from Saimaa to Lake Ladoga. Most of the lake is spotted with islands, and narrow c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mannerheim Line
The Mannerheim Line ( fi, Mannerheim-linja, sv, Mannerheimlinjen) was a defensive fortification line on the Karelian Isthmus built by Finland against the Soviet Union. While this was never an officially designated name, during the Winter War it became known as the Mannerheim Line, after Finnish Army's then commander-in-chief Field Marshal Baron Carl Gustaf Emil Mannerheim. The line was constructed in two phases: 1920–1924 and 1932–1939. By November 1939, when the Winter War began, the line was by no means complete. History of construction Background After the October Revolution in the Russian Empire, the Finns declared independence in 1917. Although the Soviet Union recognized Finland's independence, the Finns did not trust their sincerity. The relationship between the two countries deteriorated, with Soviet Russia supporting the Red Guard during the Finnish Civil War in 1918. After the victory of the White Guard, a group of Finnish communists fled to Soviet Russia and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catamaran
A Formula 16 beachable catamaran Powered catamaran passenger ferry at Salem, Massachusetts, United States A catamaran () (informally, a "cat") is a multi-hulled watercraft featuring two parallel hulls of equal size. It is a geometry-stabilized craft, deriving its stability from its wide beam, rather than from a ballasted keel as with a monohull boat. Catamarans typically have less hull volume, smaller displacement, and shallower draft (draught) than monohulls of comparable length. The two hulls combined also often have a smaller hydrodynamic resistance than comparable monohulls, requiring less propulsive power from either sails or motors. The catamaran's wider stance on the water can reduce both heeling and wave-induced motion, as compared with a monohull, and can give reduced wakes. Catamarans were invented by the Austronesian peoples which enabled their expansion to the islands of the Indian and Pacific Oceans. Catamarans range in size from small sailing or rowi ...

Canoe
A canoe is a lightweight narrow water vessel, typically pointed at both ends and open on top, propelled by one or more seated or kneeling paddlers facing the direction of travel and using a single-bladed paddle. In British English, the term ''canoe'' can also refer to a kayak, while canoes are called Canadian or open canoes to distinguish them from kayaks. Canoes were developed by cultures all over the world, including some designed for use with sails or outriggers. Until the mid-19th century, the canoe was an important means of transport for exploration and trade, and in some places is still used as such, sometimes with the addition of an outboard motor. Where the canoe played a key role in history, such as the Northern United States, Canada, and New Zealand, it remains an important theme in popular culture. Canoes are now widely used for competition and pleasure, such as racing, whitewater, touring and camping, freestyle and general recreation. Canoeing has been ...

Kayak
A kayak is a small, narrow watercraft which is typically propelled by means of a double-bladed paddle. The word kayak originates from the Greenlandic word '' qajaq'' (). The traditional kayak has a covered deck and one or more cockpits, each seating one paddler. The cockpit is sometimes covered by a spray deck that prevents the entry of water from waves or spray, differentiating the craft from a canoe. The spray deck makes it possible for suitably skilled kayakers to roll the kayak: that is, to capsize and right it without it filling with water or ejecting the paddler. ] Some modern boats vary considerably from a traditional design but still claim the title "kayak", for instance in eliminating the cockpit by seating the paddler on top of the boat ("sit-on-top" kayaks); having inflated air chambers surrounding the boat; replacing the single hull with twin hulls; and replacing paddles with other human-powered propulsion methods, such as foot-powered rotational propellers and ...

Losevo, Leningrad Oblast
Losevo (russian: Лосево; fi, Kiviniemi) is a rural locality (a station settlement) in Priozersky District, Leningrad Oblast, located at the junction of Vuoksi River and Lake Sukhodolskoye on Karelian Isthmus. It is a railway station of the Saint Petersburg–Khiytola railroad. Before the Winter War and Continuation War, it was a village of the Sakkola municipality of Finland known as Kiviniemi. Originally waters of Lake Sukhodolskoye quietly flowed into Vuoksi, but in 1818, as Burnaya River had emerged and started draining Sukhodolskoye into Lake Ladoga, the level of the former decreased dramatically by and the waterway connecting it to Vuoksi dried out. In 1857, the channel was dug, but the stream reversed direction, revealed rapids, and rendered navigation impossible. Since 1857 Lake Sukhodolskoye and Burnaya River have constituted the southern armlet of Vuoksi River, which has decreased the level of the original northern armlet by .

Rapid
Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence. Rapids are hydrological features between a ''run'' (a smoothly flowing part of a stream) and a ''cascade''. Rapids are characterized by the river becoming shallower with some rocks exposed above the flow surface. As flowing water splashes over and around the rocks, air bubbles become mixed in with it and portions of the surface acquire a white color, forming what is called "whitewater". Rapids occur where the bed material is highly resistant to the erosive power of the stream in comparison with the bed downstream of the rapids. Very young streams flowing across solid rock may be rapids for much of their length. Rapids cause water aeration of the stream or river, resulting in better water quality. Rapids are categorized in classes, generally running from I to VI. A Class 5 rapid may be categorized as Class 5.1-5.9. While Class I rapids are ...

Korela Fortress
Korela Fortress (Russian: Корела, Finnish: ''Käkisalmen linna'', Swedish: ''Kexholms slott''), at the town of Priozersk, Leningrad Oblast, Russia. Origin The original fortification was built by Karelians but the castle seen today is from medieval times. It was first mentioned in a Novgorodian chronicle of 1143 as ''Korela'', and archaeological digs have revealed a layer belonging to the 12th century. Swedish chronicles first reported of the settlement of ''Keksholm'' in 1294. Until the 16th century, the fortress belonged to the Novgorod Republic, followed by Muscovy. Novgorodians built the current stone bastions and towers in 1364 after a fire had destroyed the original wooden fortress in 1360. During a Swedish-Novgorodian war in 1314, a small Karelian force re-captured their fortress from the representatives of Novgorod. They invited Swedes to keep it against Novgorod; however, the Novgorodians reconquered the fortress. The fortress was confirmed as belonging to Nov ...
