Glossary of water terms
land area where precipitation runs off into streams, rivers, lakes, and reservoirs. It is a land feature that can be identified by tracing a line along the highest elevations between two areas on a map, often a ridge. Large drainage basins, like the area that drains into the Mississippi River contain thousands of smaller drainage basins. Also called a "watershed."
Drainage basin Definition from Encyclopedia Dictionaries & Glossaries
Wikipedia English - The Free Encyclopedia
A drainage basin or watershed (North American English usages) is an extent or an area of land where surface water from rain and melting snow or ice converges to a single point at a lower elevation, usually the of the basin, where the waters join another waterbody, such as a river, lake, reservoir, estuary, wetland, sea, or ocean. For example, a tributary stream of a brook which joins a small river, which is tributary of a larger river is thus part of a series of successively smaller area but higher elevation drainage basins (watersheds). Similarly, the Missouri and American rivers are each part of their own drainage basins/watersheds and that of the Mississippi River.
