Drainage Basin
the area from which water drains into a river is called the river's catchment. A river's watershed is the connecting ridges surrounding the watershed, and separating it from adjacent ones.
I believe its called a water shed but I'm not completely sure about that.AnswerA watershed (one word) is a ridge or other dividing line between stream catchments, although the term is (confusingly) also applied to the catchment area. Another term is drainage basin.
A stream.
The land form often formed at the mouth of a heavily silted stream is called a delta. This triangular-shaped area is created as the sediment carried by the stream is deposited when the water flow slows down upon entering a larger body of water, such as an ocean or a lake. Deltas are often fertile areas due to the rich soil deposited by the stream.
In hydrology, the upper basin refers to the area of land located at higher elevations that contributes water flow to a river or stream. This region typically contains the headwaters and tributaries of a watershed and plays a vital role in regulating the overall flow and quality of water downstream.
The stream's catchment.
A watershed is not a building, it is an area of land that contributes run off to a given lake, stream, river or other body of water. It's purpose is to supply water to the water body. (From Ask.com)
