pastas.stats.signatures.baseflow_index#

baseflow_index(series, normalize=True)[source]#

Baseflow index according to [wmo_2008].

Parameters
  • series (pandas.Series) – Pandas Series with DatetimeIndex and head values.

  • normalize (bool, optional) – normalize the time series to values between zero and one.

Return type

float

Notes

Adapted analogously to its application in streamflow. Here, a baseflow time series is separated from a 5‐day minimum groundwater head in a moving window. BFI equals the total sum of heads of original time series divided by the total sum of heads from the baseflow type of time series.
