The boundary of the drainage basin is called a drainage divide. Sometimes drainage basin is called catchment area referring to an area where water flows into a stream or a number of streams. In North America drainage basin is also called Watershed.
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).
Only waterways that are on the same side of the divide as the basin could empty into it.
