Feeder creeks, or tributaries.
They're called tributaries.
Streams and rivers flowing into a larger river or lake. They CONTRIBUTE to the main flow.
A river increases in volume as more streams join the main flow in the lower reaches.
Small streams and rivers that flow into larger ones are called tributaries. A tributary does not flow directly into a sea or ocean.
Such streams are known as the tributaries of the main river.
tributaries, the main river, and the main body of water that it flows into
The strongest current in a river system is in the main flow. There is less current in eddies and backwaters.
As silt is deposited at the river mouth, where the water flow is reduced by meeting the sea, the flow of water is obstructed and must find other channels. It is this splitting up of the main river into several streams that produces a delta.
Other streams or lakes that joins a main river is a tributary
