"1. That part of the precipitation, snow melt, or irrigation water that appears in uncontrolled surface streams, rivers, drains or sewers. Runoff may be classified according to speed of appearance after rainfall or melting snow as direct runoff or base runoff, and according to source as surface runoff, storm interflow, or groundwater runoff. 2. The total discharge described in (1), above, during a specified period of time. 3. Also defined as the depth to which a drainage area would be covered if all of the runoff for a given period of time were uniformly distributed over it." (U.S. Geological Survey, 2019)

Cuando la lluvia cae sobre la Tierra, el agua empieza a moverse y a fluir cuesta abajo a través de alcantarillas y ríos en forma de escorrentía. La escorrentía es extremadamente importante para recargar las masas de agua de la superficie y las aguas subterráneas. Además, la escorrentía modifica el paisaje por acción de la erosión. Es una parte integral del ciclo del agua (Earth Science Data Systems 2021).
