mct_inflexionpoints: Compute the inflexion point of the streamflow mass curve
In IvanHeriver/hsa-R-package: Hydrological Signature Analysis toolbox

Description Usage Arguments Value See Also

From a streamflow regime vector Qr (i.e. a inter-annual average of streamflow for each calendar day), it searches for the inflexion points in a given time window p. This functions (1) computes the derivative of Qr, (2) and smooth it using a rolling mean with a window n.

mct_inflexionpoints(
  Qcum,
  periods = c(100, 300),
  n = 30L,
  return_derivative = FALSE
)

Qcum

numeric vector. Cumulative streamflow regime vector.

If return_derivative is TRUE, a list with 3 components is returned:

data: a data.frame containing two column: the derivative of Qr (dQ) and its smoothed version (dQs). inflexion_points the indices of the two inflexions points found If return_derivative is FALSE, only the two inflexions points are returned in a length 2 numeric vector.
