I'm sorry but that isn't a proper question.
The level of a body of water that a stream flows into is called the "base level." It represents the lowest point to which a stream can erode its channel. When a stream reaches its base level, it can no longer lower its bed through erosion, leading to sediment deposition instead. This base level can be influenced by factors such as sea level, dams, or geological uplift.

The mouth of a stream is where the stream flows out into a larger body of water.
The mouth of a stream is where it meets a larger body of water, such as a lake, ocean, or another stream. It is where the stream's water flows out and mixes with the water of the larger body.

The base level is the lowest point to which a stream can erode its channel. This can be the level of the body of water into which the stream flows, such as a lake or ocean, or an artificial structure like a dam. At base level, erosion stops and sediment deposition begins.
A stream that flows into a larger stream or other body of water.
