It usually refers to the point where a [[tributary]] joins a more major [[river]], called the [[mainstem (hydrology)|mainstem]], when that major river is also the highest [[Strahler Stream Order|order stream]] in the [[drainage basin]]. The term is also used to describe the meeting of tidal or other non-riverine bodies of water, such as two [[canals]]<ref>The U.S. Army Corps of Engineers refers to the confluence of the Assawoman Canal with the Bethany Loop Canal in Delaware.

It is one of the holiest places in [[Hinduism]]. The confluence itself is called ''Triveni Sangam''. * The merging of the [[Monongahela River|Monongahela]] and [[Allegheny River|Allegheny]] Rivers. This merging point is the beginning of the [[Ohio River]], thus forming a confluence in [[Pittsburgh]]. * The [[Madison River|Madison]], [[Jefferson River|Jefferson]] and [[Gallatin River|Gallatin]] Rivers in [[Three Forks, Montana]] form the confluence of the [[Missouri River]], one of the longest rivers in the United States (2,341 miles (3,767 km)). * [[Kuala Lumpur]] the capital of [[Malaysia]], is situated at the confluence of the [[Sungai Gombak]], (previously known as Sungai Lumpur, which means muddy river) and Sungai Klang (Klang river). * [[Passau]] known also as the Dreiflüssestadt (City of Three Rivers), because the [[Danube River]] is joined there by the [[Inn River]] from the South, and the [[Ilz River]] coming out of the [[Bavarian Forest]] to the North. *[[Manaus]], [[Brazil]] is located on the [[Rio Negro (Amazon)|Rio Negro]] near its confluence with the [[Amazon River|Amazon]]. It is the chief port and a hub for the region's extensive river system. * [[Osijek]], [[Croatia]] is located on the right bank of the river [[Drava]] 25km upstream of its confluence with the [[Danube]]. *[[Belgrade]], the capital of [[Serbia]] lies at the confluence of the [[Sava]] and [[Danube]] Rivers. *The [[Hochelaga Archipelago]], including the island and city of [[Montreal]], is located at the confluence of the [[St. Lawrence River]] and [[Ottawa River]] in [[Quebec]], [[Canada]]. * The two largest rivers in Australia, the [[Darling River|Darling]] and the [[Murray River|Murray]] converge at [[Wentworth, New South Wales]] * [[Winnipeg]], [[Canada]] is located at the confluence of the [[Red River of the North|Red River]], and the [[Assiniboine River]]. The area is referred to as [[The Forks, Winnipeg|The Forks]] by locals, and has been an important trade location for over 6000 years. ==Integer latitudes and longitudes== [[Image:Confluencia 23 S x 49 W - GPS.jpg|thumb|right|200px|Lat. 23°00'00"S X Long. 49º00'00"W]] Confluence also describes a location where [[integer]] latitude and integer longitude lines cross. The point in extreme northeastern [[New Jersey]] at {{coor dms|41|0|0|N|74|0|0|W|}} is such a confluence point. The [[Degree Confluence Project]] endeavors to catalog and photograph all such points on the globe.<ref>{{cite web | title=DCP: Information | work=Degree Confluence Project | url=http://www.confluence.org/information.php | accessdate=2006-03-11}}</ref> ==References== <references/> ==See also== * [[Aber and Inver as place-name elements]] * [[Sangam at Allahabad]] {{Commons|Category:Confluences|Confluences}} [[be-x-old:Вусьце]] [[Category:Physical geography]] [[Category:Waterways]] [[Category:Coastal and oceanic landforms]] [[be:Вусьце]] [[bs:Ušće]] [[cs:Ústí]] [[de:Mündung (Gewässer)]] [[es:Confluencia]] [[fr:Confluent]] [[it:Confluenza]] [[hr:Ušće]] [[hu:Torkolat]] [[ja:合流]] [[pl:Ujście rzeki]] [[pt:Confluência]] [[ro:Confluenţă]] [[ru:Устье]] [[uk:Гирло річки]]
