Kappa3GF {UKFE}

Kappa3 distribution growth factors

Description

Estimated growth factors as a function of return period, with inputs of Lcv & LSkew (linear coefficient of variation & linear skewness)

Usage

Kappa3GF(lcv, lskew, RP)

Arguments

lcv

linear coefficient of variation

lskew

linear skewness

RP

return period

Details

Growth factors are calculated by the method outlined in Kjeldsen, T (2019), 'The 3-parameter Kappa distribution as an alternative for use with FEH pooling groups.'Circulation - The Newsletter of the British Hydrological Society, no. 142

Value

Examples

#Get a ungauged pooled Lcv and LSkew for catchment 15006
PooledRes <- as.numeric(QuickResults(GetCDs(15006), plot = FALSE)[[2]])
#Calculate Kappa growth factor for the 100-year flood
Kappa3GF(PooledRes[1], PooledRes[2], RP = 100)
