What does a basin refer to in environmental science?

In environmental science, a basin specifically refers to a geographic area that drains into a particular water body, such as a lake, river, or ocean. This concept is crucial for understanding watershed dynamics, hydrology, and water management, as it encompasses all the land and water systems that contribute to the flow of water into that water body.

The activities, land use, and climate of the basin can significantly influence water quality and quantity, making it essential to study basins in the context of environmental health and resource management. By considering this definition, one can appreciate how various factors within a basin interact to affect the ecosystems and water bodies it supports.
