Kraków-Kolna Canoe Slalom Course
The Kraków-Kolna Canoe Slalom Course is an artificial whitewater course in Poland, on the south bank of the Vistula River, in the suburb of Kolna, west of Kraków. It is fed with river water diverted around a nearby dam. The top of the course is a flatwater start pool that is covered in winter by a long white tent. Air inside the tent is heated, but the water is cold. This Olympic-standard slalom course is the site of frequent international competitions. In June 2013, it hosted the European Championships. It is part of a larger complex called the Kolna Sports and Recreation Center (Ośrodek Sportu i Rekreacji „Kolna") which includes a canal for flatwater sprint canoeing and an indoor gymnasium and swimming pool. Design The concrete channel has a flat bottom and vertical sides. The flow diverters are two pairs of concrete wing dams and clusters of vertical blue and green plastic bollards attached to peg boards on the channel bottom. A foot bridge across the channel joins th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Artificial Whitewater
An artificial whitewater course is a site for whitewater canoeing, whitewater kayaking, whitewater racing, whitewater rafting, playboating and slalom canoeing with artificially generated rapids. Course types Main types of course: Flow diversion These work by diverting a natural river through boulder placement or damming, or by creating new channels next to an existing river, possibly by a weir or power station outflow. Tidal action Created in estuaries with large tidal reaches, on a barrage across the river. The barrage is opened during a rising high tide to allow the sea water in, then shut as the tide turns. The water stored above the barrage is then forced through an artificial channel to provide water features. Pumped The nature of artificial whitewater courses necessitates the need for a drop in the river, and enough water flow to provide hydraulics. When this isn't possible (often in flat low-lying areas), electric pumps are used to lift and re-circulate the water ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Artificial Whitewater Courses
Artificiality (the state of being artificial, anthropogenic, or man-made) is the state of being the product of intentional human manufacture, rather than occurring naturally through processes not involving or requiring human activity. Connotations Artificiality often carries with it the implication of being false, counterfeit, or deceptive. The philosopher Aristotle wrote in his ''Rhetoric'': However, artificiality does not necessarily have a negative connotation, as it may also reflect the ability of humans to replicate forms or functions arising in nature, as with an artificial heart or artificial intelligence. Political scientist and artificial intelligence expert Herbert A. Simon observes that "some artificial things are imitations of things in nature, and the imitation may use either the same basic materials as those in the natural object or quite different materials.Herbert A. Simon, ''The Sciences of the Artificial'' (1996), p. 4. Simon distinguishes between the artific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buildings And Structures In Kraków
A building or edifice is an enclosed structure with a roof, walls and windows, usually standing permanently in one place, such as a house or factory. Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for numerous factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the concept, see ''Nonbuilding structure'' for contrast. Buildings serve several societal needs – occupancy, primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical separation of the human habitat (a place of comfort and safety) from the ''outside'' (a place that may be harsh and harmful at times). buildings have been objects or canvasses of much artistic expression. In recent years, interest in sustainable planning and building practi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
