... ABSTRACT In this paper we show how a new idea for how to calculate the derivatives of extrapolated 50-year return values, used in extreme load safety criteria, can be used to estimate the uncertainty in these return values resulting from uncertainty in the simulations and in the load...

... are severely overestimated by the transformed Gaussian model. In this paper, the models are fitted to ERA-Interim reanalysis wind data and used to find long-term distributions of wind speed, to estimate wind speed return values, e.g. 100-year extreme wind speed, and to compute the expected yearly frequency...

... are widely used as the data source for the estimation of extreme wave characteristics. Some researchers have studied the effect of wave modeling on the extreme wave analysis. As an example, Caires and Sterl (2005) estimated global return value for significant wave height based on a reanalysis meteorological...

... ABSTRACT One of the important bases to determine the coastal engineering design criteria for disaster prevention is confirming the return value of the storm surge elevation. To date, the long-term statistical analysis of the storm surge mainly focused on one concrete place. Actually the storm...

... ABSTRACT The return values of storm surge elevation are frequently estimated by the annual maximum value method assuming all individual data vests in a common parent distribution disregarding the fact that the inducements of the storm surge are considerably changeable. This paper examines...

... probable distribution should be selected from several candidate probabilistic models after comparison. To date, three-parameter Weibull distribution has relatively widely been used to calculate the return values. The unknown parameters of fitting distribution are mainly determined by 4 methods, namely...

Results are discussed and, in order to test the robustness of the analysis, return values for the 5 years return period...
