| Abstract
|
Major hydrological basins and their sub-basins. This dataset divides the North American continent according to its hydrological
characteristics.
The dataset consists of the following information:- numerical code and name of the major basin (MAJ_BAS and MAJ_NAME); -
area of the major basin in square km (MAJ_AREA); - numerical code and name of the sub-basin (SUB_BAS and SUB_NAME); -
area of the sub-basin in square km (SUB_AREA); - numerical code of the sub-basin towards which the sub-basin flows (TO_SUBBAS)
(the codes -888 and -999 have been assigned respectively to internal sub-basins and to sub-basins draining into the sea)
|
| Purpose
|
To assess which part of the land area flows to which river. The dataset is developed as part of an assessment of water resources
in North America.
