These areas can still be included in topographically defined basins if the hypothetical flow of water (or ice) over the surface of the ground (or ice sheet) is considered. For example, the Antarctic ice sheet can be divided into basins, [ 1 ] and most of Libya is included in the Mediterranean Sea basin even though almost no water from the ...
Watershed Boundary Dataset Subregions Map for the United States, created by the US Geological Survey. This list is non-exhaustive, as many organizations and territories have produced their own watershed map data and have published via the web. Notable datasets include: United States Watershed Boundary Dataset, [35] website (continually updated)
As of 2010 there are six levels in the hierarchy, represented by hydrologic unit codes from 2 to 12 digits long, called regions, subregions, basins, subbasins, watersheds, and subwatersheds. The table below describes the system's hydrologic unit levels and their characteristics, along with example names and codes.
Drainage basins of Asia, areas of land where precipitation collects and drains off into a common outlet, such as into a river, bay, or other body of water.The drainage basin includes all the surface water from rain runoff, snowmelt, hail, sleet and nearby streams that run downslope towards the shared outlet, as well as the groundwater underneath the earth's surface.

Map of the main drainage basins and rivers of Mongolia. The Central Asian Internal Drainage Basin or Central Asian Inland Basin is the largest of 3 major hydrological basins that cover Mongolia (cf. Arctic Drainage Basin & Pacific Drainage Basin). It is an endorheic basin. [1] [2] [3] It is further subdivided into local drainage basins. [4]
This is a map from Page 11 of a work (link below) mandated by the Environmental Protection Agency (EPA) of the US Government. The U.S. Congress mandated that all states develop a Source Water Assessment Program in the "1966 Safe Drinking Water Act".
Watershed management, the management of drainage basins; Watershed Protection and Flood Prevention Act, a United States law controlling drainage and water storage; Watershed district (Minnesota), one of a number of government entities in the US state of Minnesota which monitor and regulate the use of water in drainage basins
Watersheds of North America are large drainage basins which drain to separate oceans, seas, gulfs, or endorheic basins. There are six generally recognized hydro-logical continental divides which divide the continent into seven principal drainage basins spanning three oceans ( Arctic , Atlantic and Pacific ) and one endorheic basin.
