Hydrology

The sustained, groundwater-fed part of streamflow

Baseflow is the sustained, slowly varying component of streamflow that continues between storms and through dry spells, fed mainly by groundwater drainage and delayed subsurface flow rather than by direct storm runoff. Hall's 1968 Base-flow recessions—A review synthesised how this component declines once storm inputs cease, treating the recession curve as a signature of aquifer drainage. The referent is the groundwater-supported portion of a stream's discharge, separated from quickflow, that keeps rivers running through droughts.[1]

Unit
The groundwater-fed portion of stream discharge (volume per time, e.g. m³/s)
Recovery means
Not applicable
Measured by
Isolated by baseflow separation of the hydrograph (graphical, digital-filter, or recession-analysis methods) and summarised by the baseflow index
