drainage basin

area from which direct surface runoff from precipitation drains by gravity into a stream or other water body (3.6.7)

Note 1

The terms “watershed”, “drainage area”, “catchment”, “catchment area” and “river basin” are sometimes used for the concept of “drainage basin”.

Note 2

Groundwater drainage basin does not necessarily correspond in area to surface drainage basin.

Note 3

The geographical resolution of a drainage basin should be determined at the goal and scope stage: it may regroup different sub-drainage basins.
