View source: R/All.R

Description

Calculates the baseflow index from a daily mean flow series

Usage

1
BFI(Q, x.lim = NULL, y.lim = NULL, PlotTitle = "Baseflow plot", Plot = TRUE)

Arguments

Q

the daily mean flow series. Numeric vector

x.lim

the x axis limits of the plot. Numeric vector of length two Default is the extents of the data

y.lim

the y axis limits of the plot. Numeric vector of length two. Default is the extents of the data

PlotTitle

the title of the plot. The default is "Baseflow plot"

Plot

a logical argument with a default of TRUE. If TRUE the daily flow is plotted with the baseflow highlighted.

Details

The baseflow index is calculated using the method outlined in Gustard, A. Bullock, A. Dixon, J. M.. (1992). Low flow estimation in the United Kingdom. Wallingford, Institute of Hydrology, 88pp. (IH Report No.108)

Value

the baseflow index and if Plot equals TRUE, a plot showing the flow time series (black) and the associated baseflow (red)
