{{about|a type of river|the type of state|Tributary state}} [[File:Icon river tributary L.svg|thumb|The thick blue line is the river. The thin blue line is its tributary.]] A '''tributary''' of a [[river]] is another river that [[Flux|flows]] into it. If one river flows into a second river, then the first river is a '''tributary''' of the second river. A tributary is a body of water that flows into another body of water. The opposite of a tributary is a distributary. A distributary is a river that branches off from the main flow of water, for example in a [[river delta]]. {{wiktionary}} {{-}} {{geo-stub}} [[Category:Rivers]]
