Estimated growth factors as a function of return period, with inputs of Lcv & LSkew (linear coefficient of variation & linear skewness)
Arguments
- lcv
linear coefficient of variation
- lskew
linear skewness
- RP
return period
Value
Kappa3 distribution estimated growth factor
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
Examples
# Calculate Kappa growth factor for the 100-year flood
#assuming LCV and LSKEW of 0.165 and 0.17
Kappa3GF(0.165, 0.17, RP = 100)
