BFI+

BFI+ is a program for baseflow separation from a hydrogram. The program includes a choice of 11 methods for separation.

It includes methods such as local minimum, fixed interval or sliding interval methods; and also methods of recursive digital filters.

BFI+ was developed for baseflow separation from daily or weekly time series of river discharges. For these purposes it is possible to use one of 11 separation algorithms:

Local minimum method
Fixed interval method
Sliding interval method
One-parameter method
Boughton two-parameter method
IHACRES (three-parameter method)
BFLOW (Lynie & Holick algorithm)
Champman algorithm
Furey & Gupta filter
Eckhardt filter
EWMA filter
