List of Watershed Topics
This list embraces topographical watersheds and drainage basins and other topics focused on them.
Terms - different uses
- The source of a river or stream is the furthest place from its estuary or confluence with another river, and is alternatively known as a "watershed" and/or "headwaters" in some countries.
- The confluence is the meeting of two rivers or streams, and may sometimes be known as "headwaters".
- A drainage basin is an area of land where all surface water converges to a single point at a lower elevation. In North America, "watershed" is used for this sense, while elsewhere terms like "catchment" or "drainage area" are used.
- A drainage divide is the line that separates neighboring drainage basins. In English-speaking countries outside of North America, this is normally known as a "watershed".
