Probabilistic models of significant wave height are used to study the wave regimes outside the mouth of Van Phong bay

Abstract

In this work, several models describing the wave height probability are tested and evaluated, in order to find the typical wave height distribution function the mouth of Van Phong Bay. The final wave height distribution was selected based on multiple criteria and the proposed distribution outperformed the other parametric models tested and optimally described. According to analysis results, normal distribution; Inverse Gaussian distribution and Rayleigh distribution often give bad analysis results, should not be used for wave mode distribution in the study area. Meanwhile, the Gamma distribution usually gives the best results in 03 months: January, August and December; Nakagami distribution gives the best results in 04 months: February, June, July, October; Best Logistic distribution for 03 months: April, May, September; the best BirnbaumSaunders distribution only for November and the best LogNormal distribution for March and for the whole year distribution.
