When Rivers Collide: 10 Confluences Around the World «TwistedSifter
In geography, a confluence (also: conflux) occurs where two or more flowing bodies of water join together to form a single channel. A confluence can occur in several configurations: at the point where a tributary joins a larger river (main stem); or where two streams meet to become the source of a river. In geography, a confluence is the meeting of two or more bodies of water. Below is a collection of 10 incredible confluences around the world. Confluence of the Ilz, Danube, and Inn Rivers in Passau, Germany. Dr Peter Young writes: > On 28 Mar Nick wrote: > >> "Jonathan Morton".
Known also as a conflux, it refers either to the point where a tributary joins a larger river, called the main stem, or where two streams meet to become the source of a river of a new name, such as the confluence of the Monongahela and Allegheny Rivers in Pittsburgh, Pennsylvania creating the Ohio River.
The term is also used to describe the meeting of tidal or other non-riverine bodies of water, such as two canals or a canal and a lake. Below is a collection of 10 incredible confluences around the world. For more, there is a fascinating list of notable confluences on Wikipedia that I recommend you check out.
The confluences below were selected for their dramatic visual contrast. Thus, culturally significant confluences such as the Sangam near Allahabad, India, where the sacred rivers Ganges, Yamuna and Saraswati meet to create one of the holiest places in Hinduism, were not included for this reason. Please enjoy the list below and let us know of any other interesting confluences you are aware of.
Perhaps we can do a follow-up post if there is interest! The river on the left is the Rhone, which is just exiting Lake Lehman. The river on the right is the Arve, which receives water from the many glaciers of the Chamonix valley mainly the Mer de Glace before flowing north-west into the Rhone on the west side of Geneva, where its much higher level of silt brings forth a striking contrast between the two rivers.
Confluence of the Ilz, Danube, and Inn Rivers in Passau, Germany Photograph by b k on Flickr The Ilz is a relatively small mountain stream and has a blue-ish color while the Inn is a fairly large river flowing in from Salzburg, Austria at the top.
The Inn River has more water flow than the Danube, yet flowing away from the city the three combined rivers are called Danube. This photo is taken from the Oberhaus-fortress now a city museum on top of the Ilzstadt cliff above the city of Passau in Lower Bavaria, Germany. Brown, sediment-laden water flowing generally northeast to south from the Ohio River is distinct from the green and relatively sediment-poor water of the Mississippi River flowing northwest to south. These color differences are determined by what debris, silt, vegetation or chemicals the water caries, which clearly contrast the river they join into.
The two rivers meet in Canyonlands National Park in Utah. It carries less sediment than the Ohio River, giving it a greener tinge. The Ohio River is the largest tributary of the Mississippi and contains high levels of sediment, turning it a brown color.
Where two rivers meet – e MORFES
They are both major rivers of Northern India, and the Alaknanda travels miles through the Alaknanda Valley before meeting the dam filled and turbulent Bhagirathi River in Deyprayag. Despite its name, the Rio Negro is not technically black, but does harbor a very dark color. When it meets the Rio Solimoes, which is the name given to the upper stretches of the Amazon River in Brazil, the two rivers meet side by side without mixing.
There certainly is a stark contrast between the deep colored Rio Negro and the sandy hued Amazon River. It supports plenty of fish life and is distinguished be clear colored water, much cleaner than the Yangtze River of which it feeds into.
The Yangtze River is the longest river in Asia and is very culturally and historically important to the country. Unfortunately, its suffered industrial pollution in recent years, which is what gives it its brown color. The Rhine River, beginning its course in the Swiss Alps, flows throughout a good portion of Europe and has a history of being used for navigation and defense.
