bf_eckhardt_filter: Baseflow Separation by use of an Eckhardt Filter

In smwesten-usgs/recharge: Estimating Recharge with HYSEP, PART, and Recursive Digital Filter methods.

Description

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

Usage

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.
