dc.description.abstract	An underwater forward-scattering investigation was undertaken with random rough corrugated pressure release surface manufactured out of Styrofoam. Measured wavefields associated with the reflection caustics agree with predictions. The frequency dependence of the mth higher-order intensity moments I was measured and compared to theoretical predictions. The dependence of I2 on distance from the surface was also investigated.
