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 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.
I'm sorry but that isn't a proper question.
Yes, it is correct.
The water flows from the highest chamber to the lowest chamber. As the gate opens in the lowest chamber, the water level lowers to sea level, and the ship enters. The gate closes behind it, and water flows from the chamber above to the level of the next gate, and the process is repeated until the ship reaches the top level.
The mouth of a stream is where the stream flows out into a larger body of water.

The stream of water which flows like a river through the ocean is a current. The Gulf Stream is the most significant such current which flows from the tropics to the northern latitudes.
There is no single name for a single stream of water that flows into an ocean but headwaters would be a good one for a single stream of water into a lake
