In this paper, the effect of a random fluctuation surface on the sound field of a harmonic point source in positive sound velocity gradient shallow water is consideved. Approximate expressions for the pole equations and amplitude functions are obtained. It is found that the results of reference [1] are the limiting case of the results of this paper.
