    Encounter Analysis between Strong Wind and Rainstorm of Reservoir Based on Copula Functions by CAI Qilin, XU Danli, WANG Zhaoli, LAI Chengguang

    Published 2021-01-01
    “…The purpose of this study is to discuss the encounter problem between strong wind and rainstorm in the coastal reservoirs.The Dalongdong Reservoir,located in Taishan of Guangdong Province,was taken as a study case.The P-III,Gamma and GEV functions were used to fit the marginal distributions between three groups of rainfall extremes and one group of maximum wind speed sequence respectively.The values of different return period of the maximum wind speed and maximum rainfall in different periods were also analyzed by Archimedean Copula and Kendall function.The return periods of ‘or’,‘and’,and Kendall return period as well as the most likely design values of wind speed and rainfall were calculated.The results showed that the annual maximum daily rainfall showed a significant uptrend (p<0.05) while the yearly maximum wind speed showed a downtrend.The correlation between wind speed and rainstorm sequence was extremely weak while maximum wind speed had encountered the annual maximum rainfall during the analysis period.The values of wind speed and rainfall based on ‘or’,‘and’,and Kendall return period were smaller than that of univariate marginal distribution,while the values of “or” were larger than those with univariate marginal distribution.The elevation of main dam based on “or” joint distribution of 100a return period was larger than the actual elevation.Accordingly,this study suggested considering the encounter between strong wind and rainstorm when designing the elevation of reservoir dam in the future.…”
