pastas.stats.signatures.baseflow_stability#
- baseflow_stability(series, normalize=True)[source]#
Baseflow stability after Heudorfer et al. [2019].
- 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:
Notes
Originally developed for streamflow, here the Base Flow Index algorithm is analogously adapted to groundwater time series as a filter to separate the slow component (“baseflow”) of the time series. Then, the mean annual baseflow is calculated. Base Flow Stability is the difference of maximum and minimum annual baseflow.
