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. This runoff is called saturation excess overland flow, saturated overland flow or Dunne runoff. Reduced crop productivity usually results from erosion, and these effects are studied in the field of soil conservation.
