CONFLUENCE (GEOGRAPHY)


'Confluence of rivers'
The Mosel flows into the Rhein at Koblenz.

'Confluence of canals'
This simplified diagram shows how a section of the Industrial Canal in New Orleans also serves as the channel for the Gulf Intracoastal Waterway and the Mississippi River-Gulf Outlet Canal. At the bottom, a portion of the Intracoastal is also shown to be confluent with the Mississippi River.

'Confluence', in geography, describes the meeting of two or more bodies of water. It usually refers to the point where a tributary joins a more major river, called the mainstem, when that major river is also the highest order stream in the drainage basin. The German city name Koblenz indicates, in Germanicized form, its site at the confluence of the Rhine and the Mosel.[1]
The term is also used to describe the meeting of tidal or other non-riverine bodies of water, such as two canals[2] or a canal and a lake.[3] A one-mile (1.6 km) portion of the Industrial Canal in New Orleans accommodates the Gulf Intracoastal Waterway and the Mississippi River-Gulf Outlet Canal; ergo those three waterways are confluent there.

Integer latitudes and longitudes


Confluence also describes a location where integer latitude and integer longitude lines cross. The point in extreme northeastern New Jersey at is such a confluence point. The Degree Confluence Project endeavors to catalog and photograph all such points on the globe.[4]
