Interpolate Stage from AEP

Given a stage-frequency curve, interpolates stage values at target AEPs. Interpolation is performed in standard normal (z-variate) space for better behavior across orders of magnitude in AEP.

Usage

aep2stage(aep, stage, interp_aep)

Arguments

aep

Numeric vector of annual exceedance probabilities from the known curve.

stage

Numeric vector of stage values corresponding to aep.

interp_aep

Numeric vector of target AEPs to interpolate at.

Value

Numeric vector of interpolated stage values (same length as interp_aep).

See also

stage2aep for the inverse operation.

Examples

if (FALSE) { # \dontrun{
# Get stage at the 1% and 0.1% AEP
aep2stage(curve$AEP, curve$stage, c(0.01, 0.001))
} # }
