Tributary
The smaller river is a tributary to the big one.
when one stream meets another and they merge together, the smaller stream is known as a tributary.
It is not. It is the other way round, a stream or smaller river flowing into a larger one.
Where two rivers meet is called a confluence.
The base level of a river is the lowest place where it can flow, generally it's mouth. Therefore if a river or stream flows into another river, then the first river's base level is the point where it joins the other river.
The difference between a river and a stream is the name applied to it by local residents, and relative size. In the same region, something called a river is usually larger than something called a stream. However, something that is called a river in one place could be the same size as something called a stream in another place.
A tributary is a stream or river that flows into a larger main river. It contributes water, sediment, and nutrients to the main river system. Tributaries play a crucial role in the overall watershed ecosystem.
