Description

Extract baseflow from a daily streamflow record using the method described by Eckhardt (2005).

Usage

1
bf_eckhardt_filter(date, discharge, BFImax, alpha, STAID = "Unknown")

Arguments

date

vector of dates corresponding to each discharge, should be of class "Date." Missing values are not permitted.

discharge

the daily streamflow to be separated missing values are not permitted within the time specified by Start and end.

BFImax

maximum BFI to use in the filtering.

alpha

filter parameter.

STAID

the station identifier for the data.

Value

an object of class "baseflow" and inherits class "data.frame" of the selected data, a data frame of the baseflow information, and other information about the analysis.
