Tributaries.
All rivers usually have tributaries, regardless of age. Very few have none. The amount of tributaries is largely dependant on the terrain within the rainfall catchment area and the type of soils, rocks and barricades the river encounters on its' travels, rather than solely on the rivers' age. Some rivers have tributaries that start from underground while others may be only flowing after rainfall. Most tributaries are usually permanent waterways and the longest tributary, or continuous permanent joining tributaries, often makes up the total length of a main river. Therefore some tributaries flow into other tributaries before becoming part of the mainstream.
