Correlation Study of Rainstorm and Tidal Level Using the Maximum Entropy-Copula Method---A Case Study of Guangzhou
摘要
Abstract
Rainstorm and tides are two factors of Guangzhou’s urban waterlogging.The correlation of the rain-storm and tides is carried out in order to provide basis for risk analysis of waterlogging in Guangzhou.The model a-bout the correlation of the annual maximum tidal level and the corresponding one-hour rainfall,annual maxima of one-hour rainfall and tidal level are established.Maximum Entropy-AMH Copula is used to build conditional water-log prevention risk model,simultaneous risk model,joint risk model and encountered risk model.The results show that the simultaneous risk probability of two kinds of combinations is less than the single variable frequency;Com-pared to the correlation between the annual maximum tidal level and the corresponding one-hour rainfall,a weaker correlation is between the annual maxima of one-hour rainfall and tidal level.In the actual engineering design,im-proving the tide level (rainfall)standard can reduce the risk probability of the two variables.关键词
