Detailed explanation-1: -A tributary is a freshwater stream that feeds into a larger stream or river. The larger, or parent, river is called the mainstem. The point where a tributary meets the mainstem is called the confluence. Tributaries, also called affluents, do not flow directly into the ocean.

Detailed explanation-2: -These smaller streams are called tributaries. Streams create channels by wearing down rock and carrying it and other sediment downstream. This process is called erosion.

Detailed explanation-3: -The place where two small streams join together and results in the formation of a big river is called a DOAB. The small streams might be the tributaries of a river also.

Detailed explanation-4: -A tributary can be a tiny stream, but some are immense rivers. The Missouri River, for example, could be called a tributary to the Mississippi, even though it’s about 2, 500 miles long and receives hundreds of tributaries itself.
