By means of perturbation method, solutions exact to the second order are strictly deduced for two-dimensional random waves in water of arbitary uniform depth. Based on the solutions, the theoretical expression of bispectra is given for the first time, which is written as follows:It may be seen from the above that the bispectra of surface elevation are composed of three parts, which respectively describe the interaction between two free waves of the frequencies w and ω', and between one secondary forced wave of the frequency ω + ω' and the two free waves.The results presented in this paper might be an essential development for applying bispectral analysis to the study of the nonlinearity of the sea waves.
