A drainage basin or catchment basin is an extent or an area of land where surface water from rain, melting snow, or ice converges to a single point at a lower elevation, usually the exit of the basin, where the waters join another waterbody, such as a river, lake, reservoir, estuary, wetland, sea, or ocean.n closed (endorheic) drainage basins the water converges to a single point inside the basin, known as a sink, which may be a permanent lake, dry lake, or a point where surface water is lost underground.
Some basins, such as the Great Basin, do not drain to the sea. The water may drain into underground aquifers, or evaporate to form salt lakes. Most basins, however, are drainage basins with rivers bringing their water into the sea. Many such rivers meander through a web of islands at the river delta, and bring along a huge amount of sediment in the form of mud, clay and sand.
