Definition of Urban Runoff

Urban runoff is defined as a stream flow or the sum of surface runoff and subsurface runoff. Surface runoff occurs when the soil becomes saturated, infiltration ceases and subsequent rainfall becomes surface runoff. Subsurface runoff is rainwater that infiltrates the surface and flows much more slowly on its way to a stream than surface runoff.
