Watershed.
drainage basin
Technically, a watershed is the dividing ridge between two catchments. A Catchment is the area of land with a common drainage system.
The catchment is the correct answer. Commonly folk say 'watershed' but the watershed is the boundary (ridges etc) of the catchment.
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.
a watershed, also called a drainage basin, is an area drained by a river.
A stream's watershed and its drainage basin are often used interchangeably, but they can refer to different aspects. The watershed is the area of land that drains water, soil, and other substances into a specific water body, while the drainage basin encompasses the entire area that contributes to a river system, including all its tributaries. Essentially, the watershed is a subset of the broader drainage basin, focusing on the immediate area affecting a single stream or river. Understanding this distinction is important for effective water resource management and environmental conservation.
The land and water that drain into a river system are collectively referred to as its watershed or drainage basin. This area includes all the surface water, such as streams and rivers, as well as groundwater that contributes to the flow of the river. The watershed is crucial for managing water resources, influencing water quality, and supporting ecosystems within the river system. Activities within the watershed can significantly impact the health and sustainability of the river.
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.

Every river is part of a larger river system which includes the river and any tributaries that branch off of it.
A sub-watershed divides into smaller drainage areas known as sub-sub-watersheds or catchments. Each of these smaller areas collects and channels surface water, precipitation, and runoff into streams, rivers, or other bodies of water. This hierarchical structure helps manage water flow and quality within a larger watershed system. Additionally, each sub-sub-watershed can have distinct ecological and hydrological characteristics influenced by its topography and land use.
