fr_separate: Hydrograph Separations
In shaughnessyar/floodR: Tools for Chemical Hydrograph Separations

Description Usage Arguments Value See Also Examples

This function takes start and end dates of floods and calculates the baseflow fraction during the flood based on a two end member mixing model.

1 2	fr_separate(.data, dateVar = NULL, timeVar = NULL, dateTimeVar = NULL, tracerVar, fractionVar, starts, ends, hours, ppt, checkOverlap = TRUE)

`.data`	The working dataframe
`dateVar`	The variable holding date data
`timeVar`	The variable holding time data
`dateTimeVar`	The variable holding time data
`tracerVar`	The variable holding the tracer data for the mixing model
`fractionVar`	The name of a new variable to hold the results of the separation
`starts`	Start times of floods
`ends`	End times of floods
`hours`	Number of hours to look back as baseflow conditions for the tracerVar
`ppt`	The value to use for precipitation in mixing model
`checkOverlap`	Logical value to check if baseflows overlap

A dataframe with a new variable holding baseflow frations for each flood with attributes about which baseflow values/times were used in the separations.
