river basin
The river basin collects water from many streams and channels it toward the sea.
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.
The term "river basin" is used to describe a hydrological and geographical unit for water resource management, environmental study, and planning. * The Amazon River basin is the largest in the world, covering approximately 7 million square kilometers. * Effective conservation requires managing the entire river basin, not just the main channel. * Pollution in one part of a river basin can affect water quality hundreds of miles downstream.
