Bivariate simulation of non stationary and non Gaussian observed processes- Application to sea state parameters

A method for artificially generating operational sea state histories has be en developed. This is a distribution free method to simulate bivariate non stationary and non Gaussian random processes. This method is applied to the simulation of the bivariate process (H-s, T-p) of sea state parameters. Th e time series respects the physical constraints existing between the signif icant wave height and the peak period. Furthermore, we show that the persis tence properties of the simulations match to those of the observations. (C) 2001 Elsevier Science Ltd. All rights reserved.
