LH-Moments of the Wakeby Distribution applied to Extreme Rainfall in Thailand

This article applies the Wakeby distribution (WAD) with high-order L-moments estimates (LH-ME) to annual extreme rainfall data obtained from 99 gauge stations in Thailand. The objectives of this study investigate obtain appropriate quantile and return levels for several periods, 2, 5, 10, 25 50 years. 95% confidence intervals quantiles determined WAD are derived using bootstrap technique. Isopluvial maps estimated design values that correspond selected periods presented. LH-ME results better than more primitive method a large majority considered.
