drainage basin
An area where a river and its tributaries collect water is called a watershed or drainage basin. This region encompasses all the land that drains into a particular river system, including streams, lakes, and groundwater. Rainfall and melting snow contribute to the water flow within the watershed, ultimately feeding into the main river. Watersheds play a crucial role in managing water resources and maintaining ecosystems.
The area from which water drains into a river is called the river's watershed or drainage basin. It includes all the land and waterways that contribute runoff to that particular river system. Rainfall and other sources of water collect in the watershed, eventually flowing into the river and its tributaries.
the main river and all of its tributaries are called a river system. The land drained by the river system is called a drainage basin. Drainage basins are separated by the high land in between, known as a divide or watershed.
