GEOLOGY

Detailed explanation-1: -A watershed, also called a drainage basin or catchment, is an area drained by a river and its tributaries.

Detailed explanation-2: -The area drained by a single river system is called a drainage basin. An elevated land that separates two drainage basins is called a water divide. The main river along with its tributaries forms a river system.

Detailed explanation-3: -A watershed is an area of land that drains or “sheds” water into a specific waterbody. Every body of water has a watershed. Watersheds drain rainfall and snowmelt into streams and rivers. These smaller bodies of water flow into larger ones, including lakes, bays, and oceans.

Detailed explanation-4: -For example, the watershed of a lake would include not only the streams entering that lake but also the land area that drains into those streams and eventually the lake. Drainage basins generally refer to large watersheds that encompass the watersheds of many smaller rivers and streams.

Detailed explanation-5: -A river drainage basin is an area drained by a river and all of its tributaries. A river basin is made up of many different watersheds. A watershed is a small version of a river basin. Every stream and tributary has its own watershed, which drains to a larger stream or wetland.
