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.
Drainage Basins. A drainage basin, or catchment as it is also called, is the part of the land surface that is drained by a single river system.Most precipitation that falls on a drainage basin will eventually reach a main river and flow to the sea. drainage divide, on either side of which water will flow to separate basins, marks the perimeter of a catchment. The characteristics of such a basin, that is, the size, shape, vegetation cover, soil, and bedrock, determine how fast rainfall reaches a main river and the frequency and severity of flooding.
