Outline
The simulation of wave time series or wave elevation histories is of great significance for the accurate study of real wave-action on marine structures. In this paper, a method of simulating multi-directional irregular wave elevations is proposed based on a linear single-summation model. To evaluate the effectiveness of the proposed method, theoretical simulated regular waves, unidirectional and multidirectional irregular waves are deterministically simulated. The consistence between the simulated wave time series and the original ones is verified. The simulated accuracy range is further evaluated based on the quantitative error analysis along the spatial dimension represented by the ratio of rr/Ls (in which, rr denotes the separations of the two wave gauges, and Ls dotes the significant wave length). It is suggested that the optimum relative separations of the wave gauges should be less than 0.12Ls when the proposed method is used to reconstruct multidirectional irregular waves.
