Rapids Of Kern River, California, USA
Rapids are sections of a river where the river bed has a relatively steep gradient, causing an increase in water velocity and turbulence. Flow, gradient, constriction, and obstacles are four factors that are needed for a rapid to be created. Physical factors 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. For a rapid to form, a ...

Rhine Falls
The Rhine Falls ( / Swiss German: , a singular noun) is a waterfall on the High Rhine in Switzerland. It is the most powerful waterfall in Europe and a popular tourist attraction. The falls are located on the border between the cantons of Schaffhausen (SH) and Zurich (ZH), between the municipalities of Neuhausen am Rheinfall (SH) and Laufen-Uhwiesen/ Dachsen (ZH), ca. south of the town of Schaffhausen and close to the border with Germany. The falls are wide and high. In the winter months, the average water flow is , while in the summer, the average water flow is . The highest flow ever measured was in 1965, and the lowest, in 1921. Geology The Rhine Falls were formed during the last ice age, approximately 14,000 to 17,000 years ago, by erosion-resistant rocks narrowing the riverbed. The first glacial advances created today's landforms approximately 500,000 years ago. Up to the end of the Wolstonian Stage, approximately 132,000 years ago, the Rhine flowed westwa ...

Fluid Dynamics
In physics, physical chemistry and engineering, fluid dynamics is a subdiscipline of fluid mechanics that describes the flow of fluids – liquids and gases. It has several subdisciplines, including (the study of air and other gases in motion) and (the study of water and other liquids in motion). Fluid dynamics has a wide range of applications, including calculating forces and moment (physics), moments on aircraft, determining the mass flow rate of petroleum through pipeline transport, pipelines, weather forecasting, predicting weather patterns, understanding nebulae in interstellar space, understanding large scale Geophysical fluid dynamics, geophysical flows involving oceans/atmosphere and Nuclear weapon design, modelling fission weapon detonation. Fluid dynamics offers a systematic structure—which underlies these practical disciplines—that embraces empirical and semi-empirical laws derived from flow measurement and used to solve practical problems. The solution to a fl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sweden
Sweden, formally the Kingdom of Sweden, is a Nordic countries, Nordic country located on the Scandinavian Peninsula in Northern Europe. It borders Norway to the west and north, and Finland to the east. At , Sweden is the largest Nordic country by both area and population, and is the List of European countries by area, fifth-largest country in Europe. Its capital and largest city is Stockholm. Sweden has a population of 10.6 million, and a low population density of ; 88% of Swedes reside in urban areas. They are mostly in the central and southern half of the country. Sweden's urban areas together cover 1.5% of its land area. Sweden has a diverse Climate of Sweden, climate owing to the length of the country, which ranges from 55th parallel north, 55°N to 69th parallel north, 69°N. Sweden has been inhabited since Prehistoric Sweden, prehistoric times around 12,000 BC. The inhabitants emerged as the Geats () and Swedes (tribe), Swedes (), who formed part of the sea-faring peopl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norrbotten
Norrbotten (), sometimes called North Bothnia, is a Swedish province (''landskap'') in northernmost Sweden. It borders south to Västerbotten, west to Swedish Lapland, and east to Finland. Administration The traditional provinces of Sweden serve no administrative or political purposes, but are historical and cultural entities. In this case, however, the county is older than the province. When the new national border to the Russian Grand Duchy of Finland was established, the province of Västerbotten was divided, resulting in the formation of the Finnish municipalities of Kolari, Muonio, Pello, Tornio, and Ylitornio. However, Finnish Västerbotten is not widely recognized as a distinct historical province and is typically merged with Ostrobothnia—except for Muonio, which is considered part of Finnish Lapland. In Sweden, the northernmost counties were created in 1810, comprising the northern regions of Lapland and Västerbotten. Since then, northern Västerbotten ha ...

Ume River
The Ume River (Swedish: ''Ume älv'' or ''Umeälven'') is one of the main rivers in northern Sweden. It is around long, and flows in a south-eastern direction from its source, the lake ''Överuman'' by the Norway, Norwegian border within the Scandinavian mountain range. For large parts, the European route E12, also known as Blå Vägen (Blue Route), follows its path. The river passes through Vindelfjällen Nature Reserve and Storuman, Lake Storuman and drains into the Gulf of Bothnia on Sweden's east coast at the small town of Holmsund, and adjacent to the city of Umeå. Its chief tributary is the Vindel River, which is the biggest tributary river in Sweden. The Ume and Vindel rivers meet at the village of Vännas. At the mouth of the river, where it meets the Gulf of Bothnia, lies Obbolaön (Obbola Island). The island divides the river into two streams just as it runs out into the sea. Early history People have lived in the Ume river valley for at least five thousand years. At ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Storforsen
Storforsen is a waterfall on the Pite River in Swedish Norrbottens län is located approximately 38 km northwest of Älvsbyn. With an average flow of 187 m3/s, the rapids are one of the most voluminous in Europe. The rapids stretch over a distance of 5 km in which it drops 82 meters 60 of which are a single waterfall. Flow usually is highest at midsummer: 870 m3/s. During the floodyear 1995 a volume of 1200 cubic metres flowed down Storforsen each second. To prevent accidents the rocks surrounding the rapids are fenced, views being readily accessible to the public via ramps. While the rapids were used in previous years to transport logs, today its surroundings are part of a nature park, visited by 150,000 people each year.
