Parts of a River

From the Source to the Mouth

By:Doyle Slape

Watershed

A watershed is water that drains into a river. The water usually comes from a higher area to a lower area.

Divide

The divide is a object that separates the two larger rivers.

Great Basin

A great basin is a watershed that doesn't flow into the ocean. The great Salt Lake is an example. If there is no outflow, the water evaporates and salt is left behind.

Source

The source is the original point from which the river flows from. The source is the farthest away from the river's confluence with another river or stream.

Confluence

The confluence is a place where two rivers meet.

Headwater

The headwaters are the extreme upper reaches of a stream.

Downriver

The downriver is the area between the headwaters and the flood plain.

Floodplain

The floodplain is flat land that is adjacent to s river channel that is underwater when the river near it floods.

Tributary

The tributary is a stream or river that flows into a mainstream.

Mouth/Delta

The mouth/delta is the area formed from the deposition of sediments at the mouth of a river.
