Runoff can come from both natural processes and human activity. The most familiar type of natural runoff is snowmelt.
Difference Between Runoff And Surface Runoff? Runoff includes all the water flowing in the stream channel at any given time. Surface runoff includes only the water which reaches the stream channel without seeping into the ground.
Meaning of Runoff: Rainfall is the primary source of water for runoff generation over the land surface. In common course of rainfall occurrence over the land surface, a part it is intercepted by the vegetations, buildings and other objects lying over the land surface; and prevent to reach them on ground surface, called interception.
Surface runoff is defined as precipitation (rain, snow, sleet, or hail) that reaches a surface stream without ever passing below the soil surface. It is distinct from direct runoff, which is runoff that reaches surface streams immediately after rainfall or melting snowfall and excludes runoff generated by the melting of snowpack or glaciers.

Runoff is the flow of water across the earth, and is a major component in the hydrological cycle. Runoff that flows over land before reaching a watercourse is referred to as surface runoff or overland flow. Once in a watercourse, runoff is referred to as streamflow, channel runoff, or river runoff. Urban runoff is surface runoff created by ...
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.
Jun 8, 2019 · When water "runs off" the land surface, that’s runoff! Due to gravity, the water you wash your car with runs down the driveway as you work, and rain runs downhill. Runoff is an important component of the water cycle.
Jun 6, 2018 · 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.
