perimeter/drainage divide

The water that falls into the naturally enclosed area all flows down toward a single stream directly, or to several streams, and than into the largest, central stream in the drainage basin.

Some of the drainage basins are very small, only occupying few square km, while some are enormous are larger that the majority of the countries in the world.
