A drainage basin is an extent or area of land where water from rain and melting snow or ice drains downhill into a body of water, such as a river, lake, reservoir, estuary, wetland, sea or ocean. A drainage divide is the line separating neighbouring drainage basins (catchments).
The area of land drained by a river and its tributaries is called a drainage basin. They are separated from each other by an area of higher ground called a watershed or divide. This watershed determines the direction in which water flows.

The area between drainage basins is called a watershed divide or a water parting. It marks the boundary where water flows in different directions to separate one drainage basin from another.
Drainage basins are separated from each other by an area of higher ground called a divide. This divide helps to direct water within a specific drainage basin, preventing water from flowing into neighboring basins.
A divide.
It is a hydrological divide or drainage divide. Some also call it a ridgeline, watershed or water parting.
the main river and all of its tributaries are called a river system. The land drained by the river system is called a drainage basin. Drainage basins are separated by the high land in between, known as a divide or watershed.
