A tributary is a freshwater stream the feeds right into a bigger stream, river or other body the water. The larger, or parent, river is called the mainstem.

A tributary is a freshwater stream the feeds into a bigger stream or river. The larger, or parent, river is dubbed the mainstem. The suggest where a tributary meets the mainstem is dubbed the confluence. Tributaries, additionally called affluents, do not flow directly into the ocean.
Most huge rivers are formed from countless tributaries. Each tributary drains a various watershed, moving runoff and also snowmelt from the area. Each tributary"s watershed makes up the larger watershed that the mainstem. 
The Missouri River"s enormous watershed, because that example, is developed by the watersheds of dozens of tributaries prolonging from the provinces of Alberta and Saskatchewan, Canada, v seven states in the upper Midwest that the U.S. The Missouri, in turn, is the largest tributary the the Mississippi River, which that meets in ~ a confluence in St. Louis, Missouri. The Mississippi river watershed is the fourth-largest in the world.
A "left-bank tributary" or "right-bank tributary" suggests the next of the flow a tributary enters. Once identifying a left-bank or right-bank tributary, a geographer looks downstream (the direction the flow is flowing). 
The Euphrates River, the longest river in southwestern Asia, follow me 2,700 kilometers (1,678 miles). The small streams the feed the Euphrates originate in the hills of east Turkey. These streams come to be the Balikh and the Sajur Rivers, which join the Euphrates at different confluences in Syria. The Balikh is a left-bank tributary of the Euphrates, if the Sajur is a right-bank tributary.
Sometimes, tributaries have the same name as the river right into which they drain. These tributaries are referred to as forks. Different forks space usually determined by the direction in i beg your pardon they flow into the mainstem. 
The Shenandoah River, because that example, flows through the U.S. States of West Virginia and Virginia. It has actually two long tributaries, the phibìc Fork and South Fork, which fulfill at a confluence in Harpers Ferry, West Virginia.
The the contrary of a tributary is a distributary. A distributary is a stream that branches off and also flows except the mainstem the a currently or river. The procedure is called river bifurcation. 
At the Continental divide in the U.S. State the Wyoming, the tiny North Two ocean Creek bifurcates into Pacific Creek and also Atlantic Creek. The water from every of this distributaries flows into the s for which the is named.
There space two leading techniques geographers and potamologists (people who research rivers) usage to divide tributaries. 
The first method list a river"s tributaries beginning with those closest to the source, or headwaters, that the river. The more quickly tributaries of the Rhine River, because that example, include the Thur flow of Switzerland and also the Ill river of Austria. The Rhine, one of the longest rivers in Europe, has actually its resource in the Alps and its mouth in the phibìc Sea.
The second an approach lists a river"s tributaries by your flow. Little streams are identified with low numbers, while larger tributaries have higher numbers. The Tshuapa and Kasai Rivers space both left-bank tributaries that the Congo River, the deepest flow in the world. The Tshuapa is a smaller sized river, and also has a lower tributary ranking, 보다 the Kasai. 
Human activity in tributaries is frequently responsible for polluting the mainstem. The river carries all the runoff and pollution from all its tributaries. 
Rivers v tributaries that drainpipe land that is not offered for agriculture or development are usually less polluted than rivers through tributaries in agricultural or metropolitan areas. 
Development, not size, determines the pollution of rivers. The Amazon River, through the largest drainage basin in the world, is much cleaner than the Hudson River, because that instance. Tributaries to the Amazon flow through undeveloped areas of the Andes Mountains and also rain forests in Brazil, Venezuela, Colombia, Peru, and also Bolivia. The Hudson flow flows through one of the largest urban areas on Earth, brand-new York City.

The Ganges has an ext than a dozen tributaries, including the Alakananda and Bhagirathi, above.

Three RiversThe Allegheny and also Monongahela rivers space tributaries the the Ohio River. The confluence of these rivers is in Pittsburgh, Pennsylvania. 3 Rivers is the name of a ar in Pittsburgh, and the sports stadium supplied by the Pittsburgh Steelers and also Pittsburgh Pirates till 2000.

Spiritual TributaryPeople have constructed many good cities in ~ points wherein tributaries join major rivers. In India, Allahabad is a city of an ext than 1 million people developed where the Yamuna and also the Saraswati rivers sign up with the Ganges River. Allahabad is thought about one that the holiest areas in the Hindu religion, and also some believe it is wherein Brahma, the god of creation, offered his an initial sacrifice after developing the world.

the art and science of cultivating land because that growing crops (farming) or increasing livestock (ranching).
