'''Baseflow''' (also called '''drought flow''', '''groundwater recession flow''', '''low flow''', '''low-water flow''', '''low-water discharge''' and '''sustained''' or '''fair-weather runoff''') is the portion of [[streamflow]] that comes from "the sum of deep subsurface flow and delayed shallow subsurface flow".

[[Hydrograph separation|Baseflow separation]] is often used to determine what portion of a streamflow [[hydrograph]] occurs from baseflow, and what portion occurs from [[overland flow]]. Common methods include using [[isotope hydrology|isotope tracing]] and the software programprograms [http://water.usgs.gov/software/HYSEP/ HYSEP], amongor others[http://hydrooffice.org/Software/Tool.aspx?ID=2&Name=BFI%2b BFI+].
