Service Description: The Transboundary Freshwater Spatial Database contains physical, socioeconomic, and political data relating to the world's international river basins (which is synonymous with watershed and catchment). First and foremost, this spatial database contains the delineations of the world's international river basins and their associated basin country units, which are the area of a particular basin in a certain country. By breaking down the international river basins into BCUs - basin country units - we are able to understand how landcover, precipitation, population, withdrawal, consumption, and more vary between countries all within the same international river basin. These data help us, in the PWCMT at OSU and other researchers worldwide, to manage our shared waters and to promote cooperation over them.

The 2018 Spatial Database update identifies 310 international river basins, which is defined as having two general characteristics:
system of surface and hydrologically connected groundwater flowing to a common terminus
perennial (year-round) flow crossing or following an international political boundary
The river basin, then, is the area that can be extrapolated as area of land that drains waters to the common terminus, which is an ocean, sea, or terminal inland water body. For more information about the 2018 update, please see the following paper:
