Runoff, in hydrology, quantity of water discharged in surface streams.Runoff includes not only the waters that travel over the land surface and through channels to reach a stream but also interflow, the water that infiltrates the soil surface and travels by means of gravity toward a stream channel (always above the main groundwater level) and eventually empties into the channel.

Drainage basin, also called catchment area, or (in North America) watershed, area from which all precipitation flows to a single stream or set of streams. Your hands have become a catchment.

The outside edge of a catchment is always the highest point. The catchment boundary to any required (usually gauged) point on the river network is defined by applying GIS tools to an appropriate digital elevation model. Delineation is based entirely on topographic and river network information. Catchment areas may drain their water into other lower lying basins or into a single place, usually a lake, in the case of a closed catchment. (a). The catchment area is the area from which rainfall is collected. 1 Drainage basin. a´reae, areas) (L.) a limited space or plane surface.
