Nonstationary extreme value analysis for estimation of design water level of Vung Tau station

Abstract

In this study, the trend in the extreme water level of Vung Tau station is indicated by Mann-Kendall test. Besides, the extreme water level time series is modelled under nonstationary condition. The results show that the increasing trend has been found in extreme water level data of Vung Tau station over the period of 1980-2019. Besides, the design water level estimates under the stationary condition are lower than those under the nonstationary condition in the study area
