Flow Duration Curve
Description
Produces a flow duration curve plot with optional Gustard type-curves that can be used to estimate catchment permeability.
Usage
FDC(
TS,
normalize.flow = TRUE,
ylog = TRUE,
title = FALSE,
normal = FALSE,
gust = TRUE,
ylimits = NULL
)
Arguments
TS |
A data frame of streamflow time series loaded with |
normalize.flow |
Boolean to indicate whether or not the streamflow should be normalized by dividing by the mean. Default is TRUE. Gustard's Type Curves can only be included when this is TRUE. |
ylog |
Boolean indicating whether or not to plot the y-axis as a logarithmic scale. Default is TRUE. |
title |
optional plot title. Default is FALSE indicating no plot title is wanted.
Set to TRUE to use the the default plot title, which will
look for 'plot title' attribute of the data.frame set by
|
normal |
A logical indicating whether to use normal probability x-axis (normal=TRUE) or a linear probability x-axis (default, normal=FALSE). |
gust |
A logical indicating whether to include Gustard's Type Curves (default is TRUE). Type curves can only be plotted when normalize.flow is TRUE. |
ylimits |
A numeric vector of length 2 to set y-axis limits (default is NULL). |
