Definition of a river system

Answer 1

A river system refers to a network of interconnected rivers, streams, and tributaries that form a drainage basin or watershed. It includes both the main river and its branches as well as the surrounding land and water bodies that contribute water to the system. The main river acts as a trunk, receiving water from its tributaries and draining it into an ocean, sea, lake, or another river system. A river system plays a crucial role in the natural water cycle by collecting and transporting water, sediments, nutrients, and other substances, shaping the landscape, and supporting various ecosystems and human activities.
