| Abstract: | This paper proposes the stochastic analysis method of sea environment simulated by numerical models, such as wave height, current field, design sea levels and longshore sediment transport. Uncertainty and sensitivity analysis of input and output factors of numerical models, their long-term distribution and confidence intervals are described in this paper. |

| Keywords: | uncertainty and sensitivity analysis sea environment sediment transport confidence interval |
