A Study on the Effect of the Estimation Accuracy of Extreme Distribution of Waves on the Probability of Failure of Breakwaters in view of Sliding Displacement

The estimation accuracy of extreme distribution of waves is one of the parameters that affects the probability of failure of breakwaters in view of sliding displacement. In this study, first, the correlation of probability of failures for precise extreme distributions of waves and those for estimated distributions was discussed by conducting a series of Monte Carlo simulation. Next, the method of setting the coefficient of variation of deepwater wave height accuracy for the Monte Carlo simulation was discussed. The proposed method evaluates the coefficient of variation for the arbitrary target confidence level of failure probability.
