bf.stats: Baseflow statistics

In FlowScreen: Daily Streamflow Trend and Change Point Screening

Description

This function estimates the baseflow and calculates the mean, max, and min baseflow and baseflow index for a user defined time period.

Usage

bf.stats(TS, by = "hyear")

Arguments

TS	output from create.ts containing a data.frame of flow time series
by	summary period. Options are "year", "hyear", "month", or "doy". Default is "hyear".

Details

This function calls bf_eckhardt to complete the baseflow separation.

Value

Returns a data.frame with the following columns:

• By - Unique values representing the summary periods, e.g. a list of unique years, months, or days of year

• MeanQ - Mean daily streamflow for the summary period, in m3/s

• MeanBF - Mean daily baseflow for the summary period, in m3/s

• MaxBF - Maximum daily baseflow for the summary period, in m3/s

• MinBF - Minimum daily baseflow for the summary period, in m3/s

• BFVol - Baseflow volume for the summary period, in km3

• MeanBFI - Mean daily baseflow index for the summary period, dimensionless

• MaxBFI - Maximum daily baseflow index for the summary period, dimensionless

• MinBFI - Minimum daily baseflow index for the summary period, dimensionless
