Standard construction function of BaseflowFilter
objects, used by package baseflow
to store filtering information for a given catchment. The object is created with NA values of baseflow and level of filtering reservoir, it is then necessary to run perform_filtering
function to compute them.

BasinData |
A |
alpha |
Numeric parameter of the filtering reservoir. Its dimension depends on the used update function. |
updateFunction |
Character string giving reservoir function : must be one of |
A BaseflowFilter
object containing provided data. Baseflow numeric field R
and reservoir level V
are filled with NA
, it is thus necessary to call perform_filtering
function to compute R
and V
.
