River Basin
A drainage basin is an extent or an area of land where surface water from rain and melting snow or ice converges to a single point, usually the exit of the basin, where the waters join another waterbody, such as a river, lake, reservoir, estuary, wetland, sea, or ocean.
A River Basin
Tributaries - smaller rivers flowing into a larger river.
A Watershed - an area of highland surrounding the river basin.
A confluence - where a river joins another river.
Source - the start of a river.
Mouth - Where a river meets a lake, the sea or an ocean.
