fdc_values: Compute the flow duration curve (FDC)

In IvanHeriver/hsa-R-package: Hydrological Signature Analysis toolbox

Description

Given a vector of streamflow values Q, this function computes a data.frame with two columns:

• p: probabilities of exceedance

• Q: corresponding streamflow values

Usage

fdc_values(Q, n = 1000, sort = FALSE, na.rm = TRUE)

Arguments

Q	numeric vector. Streamflow values.
n	number of rows in the resulting data.frame (should be smaller than the length of Q).
sort	logical. Whether the fdc should be computed by sorting the streamflow values (TRUE) or by using the quantile function (FALSE, default).
na.rm	logical. Should the missing values be ignored? (must be TRUE if the quantile function is used and Q contains missing values)

Value

a data.frame with two columns:

• p: probabilities of exceedance

• Q: corresponding streamflow values
