Vaajanvirta
The Vaajanvirta, also spelled as Vaajavirta, is a long river in the Vaajakoski area of Jyväskylä, Finland. It begins from the lake Leppävesi and discharges into Lake Päijänne. The river's basin has a surface area of , which includes many major Central Finnish lakes, such as Lake Keitele. The river is part of the Keitele Canal's route, which connects the lakes Päijänne and Keitele. The Finnish national road 4 and the Jyväskylä–Pieksämäki railway also cross the river. Geography Vaajanvirta begins from the western part of lake Leppävesi with a surface at above sea level. Aside from Leppävesi, Vaajanvirta also gets water from Hupelinlampi, a small lake near Kanavuori, whose outlet discharges into the Saltunlahti bay of the river. The river has three islands: Lapinsaari, Naissaari and Varassaari. Lapinsaari is uninhabited, while Naissaari and Varassaari are connected to the mainland via bridges.

Rivers Of Finland
This is a list of rivers of Finland. Listing begins with rivers flowing into the Baltic sea, from the north, that is from the Swedish border. Tributaries are listed down the page in an upstream direction. Water flows from Finland directly to the Baltic Sea, which is divided here into the Gulf of Bothnia and Gulf of Finland, and the Archipelago Sea between them. Some rivers flow to Russia, ending either to Gulf of Finland or to the White Sea, and a few to the Arctic Ocean through Russia or Norway. There are many lakes in Finland and this listing also includes several lakes through which the rivers flow or begin from. Due to the great number of lakes especially in the Finnish Lakeland, where watercourses tend to consist of chains of lakes rather than long rivers, some rivers with a large catchment area can also be quite short or there may only be a short rapid between large lakes, like for example Tammerkoski in Tampere.

Jyväskylä–Pieksämäki Railway
The Jyväskylä–Pieksämäki railway (, ) is a 1,524 mm (5 ft) railway in Finland, running between the Jyväskylä and Pieksämäki stations. History The decision to build the line was made in 1912, and the most difficult and expensive of the route options was chosen. The decision was influenced by the experience gained from the construction of the curved and hilly Haapamäki–Jyväskylä railway, which proved inadequate for the growing train traffic. The line became straightforward - plans to bypass Leppälahti and Pönttövuori were abandoned. In turn, the population centers of Hankasalmi and Kankainen were bypassed, which eventually led to the creation of the station villages of Hankasalmi, Sauvamäki and Venetmäki. The main challenges of the construction process were at the western end of the line - namely, the cliffs between Vaajakoski and Leppälahti, the long lake embankments and the tunnel through the Pönttövuori. The Jyväskylä-Pieksämäki line was the l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kaplan Turbine
The Kaplan turbine is a propeller-type water turbine which has adjustable blades. It was developed in 1913 by Austrian professor Viktor Kaplan, who combined automatically adjusted propeller blades with automatically adjusted wicket gates to achieve efficiency over a wide range of flow and water level. The Kaplan turbine was an evolution of the Francis turbine. Its invention allowed efficient power production in low-head applications which was not possible with Francis turbines. The head ranges from and the output ranges from 5 to 200 MW. Runner diameters are between . Turbines rotate at a constant rate, which varies from facility to facility. That rate ranges from as low as 54.5 rpm ( Albeni Falls Dam) to 450 rpm. Kaplan turbines are now widely used throughout the world in high-flow, low-head power production. Development Viktor Kaplan, living in Brno, Austria-Hungary (now in the Czech Republic), obtained his first patent for an adjustable blade propeller turbine in 19 ...

Fish Migration
Fish migration is mass relocation by fish from one area or body of water to another. Many types of fish migrate on a regular basis, on time scales ranging from daily to annually or longer, and over distances ranging from a few metres to thousands of kilometres. Such migrations are usually done for better feeding or to reproduce, but in other cases the reasons are unclear. Fish migrations involve movements of schools of fish on a scale and duration larger than those arising during normal daily activities. Some particular types of migration are ''anadromous'', in which adult fish live in the sea and migrate into fresh water to spawn; and ''catadromous'', in which adult fish live in fresh water and migrate into salt water to spawn. Marine forage fish often make large migrations between their spawning, feeding and nursery grounds. Their movements are associated with ocean currents and with the availability of food in different areas at different times of the year. The migratory ...

Brown Trout
The brown trout (''Salmo trutta'') is a species of salmonid ray-finned fish and the most widely distributed species of the genus ''Salmo'', endemic to most of Europe, West Asia and parts of North Africa, and has been widely introduced globally as a game fish, even becoming one of the world's worst invasive species outside of its native range. Brown trout are highly adaptable and have evolved numerous ecotypes/subspecies. These include three main ecotypes: a riverine ecotype called river trout or ''Salmo trutta'' morpha ''fario''; a lacustrine ecotype or ''S. trutta'' morpha ''lacustris'', also called the lake trout (not to be confused with the lake trout in North America); and anadromous populations known as the sea trout or ''S. trutta'' morpha ''trutta'', which upon adulthood migrate downstream to the oceans for much of its life and only returns to fresh water to spawn in the gravel beds of headstreams. Sea trout in Ireland and Great Britain have many regional names: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dredging
Dredging is the excavation of material from a water environment. Possible reasons for dredging include improving existing water features; reshaping land and water features to alter drainage, navigability, and commercial use; constructing dams, dikes, and other controls for streams and shorelines; and recovering valuable mineral deposits or marine life having commercial value. In all but a few situations the excavation is undertaken by a specialist floating plant, known as a dredger. Usually the main objectives of dredging is to recover material of value, or to create a greater depth of water. Dredging systems can either be shore-based, brought to a location based on barges, or built into purpose-built vessels. Dredging can have environmental impacts: it can disturb marine sediments, creating dredge plumes which can lead to both short- and long-term water pollution, damage or destroy seabed ecosystems, and release legacy human-sourced toxins captured in the sediment. ...
