The source is known as the headwaters or the head of the stream. A stream may have more than one sources and when two streams come together it’s called a confluence. The smaller of the two streams is a tributary of the larger stream. A stream may create a pool where water slows and becomes deeper.

A tributary is a freshwater stream that feeds into a larger stream, river or other body of water.

A river is a natural flow of running water that follows a well-defined, permanent path, usually within a valley. A stream (also called a brook or a creek) is a natural flow of water that follows a more temporary path that is usually not in a valley.

The Yarlung Tsangpo is considered the highest river in the world.

The deepest part of a river bed is called a channel. The bed (also called the river bed) is the bottom of the river (or other body of water).

A tributary or affluent is a stream or river that flows into a larger stream or main stem (or parent) river or a lake. A confluence, where two or more bodies of water meet together, usually refers to the joining of tributaries.

There are four main types of estuaries: coastal plain estuaries/drowned river valleys, tectonic estuaries, bar built estuaries, and fjords.

A confluence occurs when two or more flowing bodies of water join together to form a single channel. Confluences occur where a tributary joins a larger river, where two rivers join to create a third or, where two separated channels of a river, having formed an island, rejoin downstream.

It can either be a tributary or a distributary, where a river joins another or separate from one respectively. It is called a confluence. A tributary is a smaller river joining a larger one.

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.

“Confluence” is the word used to denote the place where two or more water bodies meet, may be it that a tributary meets the main riveror two rivers meet to form a new river, or three or four rivers meet at a point.

You know Pittsburgh has three rivers: the Allegheny, Monongahela and Ohio.

The area around the Tigris and Euphrates in Mesopotamia is known as the “Cradle of Civilization” because it is believed that settled society began there. In Pittsburgh, we owe the existence of our own city to its three rivers: The Allegheny, Monongahela, and Ohio.

Pittsburgh Public Safety spokeswoman Sonya Toler said there are no laws against swimming in the Allegheny, Monongahela or Ohio, and most days one can spot plenty of people boating, rowing, fishing, tubing or paddleboarding. And people swimming,” Quesen said. “Rivers are not like lakes; it is never the same water twice.
