Interpolate Stage from AEP

Source: R/interpolation_functions.R
aep2stage.Rd

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

# Get stage at the 1.12% and 0.175% AEP
aep2stage(jmd_rfa_expected$AEP, jmd_rfa_expected$Expected, c(0.0112,1.75E-3))
