that is what is called a basin
Drainage basin is also called catchment, catchment area, catchment basin, drainage area, river basin, and water basin. It is an area of land. All water that falls on that land flows into one river.

A River basin is the portion of land drained by a river and its tributaries. It encompasses all of the land surface dissected and drained by many streams and creeks that flow downhill into one another, and eventually into one river. The final destination is an estuary or an ocean. As a bathtub catches all the water that falls within its sides, a river basin sends all the water falling on the surrounding land into a central river and out to the sea.
Oceans themselves are not drainage basins; rather, they are large bodies of saltwater that receive water from various drainage basins. A drainage basin, or watershed, is an area of land where all precipitation collects and drains into a common outlet, such as a river, lake, or ocean. In this context, rivers and streams within drainage basins ultimately carry water to oceans, making the oceans the final destination for the water collected in these basins.
The drainage basin includes all the surface water from rain runoff, snowmelt, hail, sleet and nearby streams that run downslope towards the shared outlet, as well as the groundwater underneath the earth's surface.
A drainage basin is the area of land where all the water that falls as precipitation drains downhill into a body of water such as a river, lake, or ocean. The basin is defined by the natural topography of the land, with all the water within it ultimately flowing towards a common outlet.
Drainage Basin
A drainage basin is an area of land where all surface water converges to a single point, such as a river or lake. It is also known as a watershed or catchment area, and it plays a crucial role in the hydrological cycle by collecting and channeling water runoff. The boundaries of a drainage basin are typically defined by the topographic divide, where water flows in different directions.
Land drained by a river is a watershed. This is an area of land that feeds all the water running under it and draining off of it into a body of water.
All rivers must have a river basin (drainage basin)
