List of drainage basins by area

The list of drainage basins by area identifies basins, sorted by area, which drain to oceans, mediterranean seas, rivers, lakes and other water bodies. All basins larger than are included as well as selected smaller basins. It includes drainage basins which do not flow to the ocean. It includes oceanic sea drainage basins which have hydrologically coherent areas.
The oceans drain approximately 83% of the land in the world. The other 17% – an area larger than the basin of the Arctic Ocean – drains to internal endorheic basins.
Note that there are substantial areas of the world that do not "drain" in the commonly understood sense. In Arctic deserts much of the snowfall sublimates directly into the air and does not melt into flowing water, while in equatorial deserts precipitation may evaporate before joining any substantial water course. However, these areas can still be included in topographically defined basins if one considers the hypothetical flow of water, and thus nutrients or pollutants, over the surface of the ground ; this is the approach taken here. For example, the Antarctic ice sheet can be divided into basins, and most of Libya is included in the Mediterranean Sea basin even though almost no water from the interior actually reaches the sea.
s, showing drainage into the major oceans and seas of the world--Drainage basins of the principal oceans and seas of the world. Grey areas are endorheic basins that do not drain to the ocean.
