Using the reductive perturbation method, the modulation ol' gravity waves pro-pagating over uneven bottom is investigated. It is shown that such a process can be de-scribed by the nonlinear Schr6dinger equation with art additional pure imaginarypotential. For the case when the depth variation is weak, we have derived anotherequation, which can be formally transformed into the classical nonlinear Schr6dingerequation. Based upon this equation, it is found that various types of envelopesolitons and a phase jump solution may diffuse owing to stochastic variation of thedepth.
