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.
A catchment is an area of land where water collects when it rains, often bounded by hills. As the water flows over the landscape it finds its way into streams and down into the soil, eventually feeding the river.Some of this water stays underground and continues to slowly feed the river in times of low rainfall.very inch of land on the Earth forms part of a catchment. Catchments can range greatly in size from small urban sub-catchments such as Prospect Creek that feeds part of the larger Georges River Catchment, to massive catchments such as the Murray-Darling Basin that spans three states.
