river basin

The river basin collects water from many streams and channels it toward the sea.

Definition

Noun: 1. A drainage basin or watershed: The entire geographical area of land where all surface water from rain, snowmelt, or other sources drains into a single river system and ultimately flows out through one common outlet, such as a larger river, lake, or ocean. It is defined by the natural topography and divides (like hills or mountains) that direct water flow.
