Confluence of rivers, the Mosel flows into the Rhine at Koblenz. The Name "Koblenz" itself has its origin in the latin name "Confluentes"

Confluence of the Bhagirathi and Alaknanda Rivers to produce the Ganges at Devprayag, India. Note the swirl of sediment from the Alaknanda.

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.

The confluence of the Rio Negro (black) and the Rio Solimões (sandy) near Manaus, Brazil.

In geography, a confluence is the meeting of two or more bodies of water. Known also as a conflux,^[1] 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^[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; therefore those three waterways are confluent there.

Map of the Earth

Geography (from Greek γεωγραφία - geographia, lit. "earth describe-write"^[1]) is the science that studies the lands, the features, the inhabitants, and the phenomena of the Earth.^[2] A literal translation would be "to describe or write about the Earth". The first person to use the word "geography" was Eratosthenes (276-194 BC). Four historical traditions in geographical research are the spatial analysis of the natural and the human phenomena (geography as the study of distribution), the area studies (places and regions), the study of the man-land relationship, and the research in the earth sciences.^[3] Nonetheless, the modern geography is an all-encompassing discipline that foremost seeks to understand the Earth and all of its human and natural complexities—not merely where objects are, but how they have changed and come to be. Geography has been called "the world discipline" and "the bridge between the human and the physical science". Geography is divided into two main branches: the human geography and the physical geography.^[4][5][6]
