Tributaries and dis tributaries of a river----
Tributaries are small streams of water that originates from the glacier and join together to form a river. Dis tributaries are formed when the river breaks down into small stream-lets or channels.
What are the characteristics of tributaries?
Tributaries are generally features at the head of a drainage basin .
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.
What are called distribributary?
A distributary, or a distributary channel, is a stream that branches off and flows away from a main stream channel. Distributaries are a common feature of river deltas. The phenomenon is known as river bifurcation. The opposite of a distributary is a tributary, which flows towards and joins another stream.
Why do rivers form distributaries at the mouth?
As the river approaches the sea, the speed of the flowing water decreases and the river begins to break up into a number of streams called distributaries. The river becomes so slow that it begins to deposit its load. Each distributary forms its own mouth. The collection of sediments from all the mouths forms a delta.
