Meet regulatory requirements. Runoff may be defined as that part of precipitation as well as any other flow contributions which appear in surface streams of either perennial or seasonal nature.. It is the flow collected from a drainage basin appearing at the outlet of the basin or catchment.

From Mays, 2011, Ground and Surface Water Hydrology. A D hour unit hydrograph is the characteristic response of a given watershed to a unit volume (e.g. 1 in or cm) of effective water input (usually rain) applied at a constant rate for D hours.
