Abstract EN
Extremes precipitation may cause a series of social, environmental, and ecological problems.
Estimation of frequency of extreme precipitations and its magnitude is vital for making decisions about hydraulic structures such as dams, spillways, and dikes.
In this study, we focus on regional frequency analysis of extreme precipitation based on monthly precipitation records (1999–2012) at 17 stations of Northern areas and Khyber Pakhtunkhwa, Pakistan.
We develop regional frequency methods based on L-moment and partial L-moments (L- and PL-moments).
The L- and PL-moments are derived for generalized extreme value (GEV), generalized logistic (GLO), generalized normal (GNO), and generalized Pareto (GPA) distributions.
The Z-statistics and L- and PL-moments ratio diagrams of GNO, GEV, and GPA distributions were identified to represent the statistical properties of extreme precipitation in Northern areas and Khyber Pakhtunkhwa, Pakistan.
We also perform a Monte Carlo simulation study to examine the sampling properties of L- and PL-moments.
The results show that PL-moments perform better than L-moments for estimating large return period events.
