“…Both weather systems generate maximum waves of 7-m height and periods of 9-12 s. The modeled liquefaction from these waves did not extend below 15 m water depth. These types of liquefaction analyses are complex and not well correlated with field experience (Nataraja and Gill, 1983).…”

“…Storm waves can impose significant shear stresses in sediments on the ocean bottom, even where the water depth exceeds 60 to 70 m (E. C. Clukey, Exxon Corp., written comm., 1992). Wave-induced cyclic shear stresses are thought to cause liquefaction in sands and granular deposits in a manner analogous to seismically induced liquefaction (Nataraja and Gill, 1983). The action of waves pounding on beaches also seems plausible as a mechanism tor forming tluidization features.…”

“…Verruijt (1982) considered only standing waves in his analytical solution. Madsen (1978), Yamamoto et al (1978), and Nataraja and Gill (1983) took into consideration the flow in the bed, compressibility of water and elastic bed in their formulation. Yamamoto et al noted that even a very small amount of air trapped in the bed would increase the volume compressibiHty of water very drastically (Verruijt, 1969).…”

Wave propagation in porous media is of interest in various diversified areas of science and engineer ing. The theory of the phenomenon has been studied extensively in soil mechanics, seismology, acoustics, earthquake engineering, ocean engineering, geophysics, and many other disciplines. This review presents a general survey of the Hterature within the context of porous media mechanics. Following a review of the Biot's theory of wave propagation in Unear, elastic, fluid saturated porous media which has been the basis of many analyses, we present various analytical and numerical solutions obtained by several researchers. Biot found that there are two dilatational waves and one rotational wave in a saturated porous medium. It has been noted that the second kind of dilatational wave is highly attenuated and is associated with a diffusion type process. The influence of couphng between two phases has a decreasing effect on the first kind wave and an increasing effect on the second wave. Procedures to predict the hquefaction of soils due to earthquakes have been reviewed in detail. Extension of Biot's theory to unsaturated soils has been discussed, and it was noted that, in general, equations developed for saturated media were employed for unsaturated media by replacing the density and compressibility terms with modified values for a water-air mixture. Various approaches to determine the permeabihty of porous media from attenuation of dilatational waves have been described in detail. Since the prediction of acoustic wave speeds and attenuations in marine sediments has been extensively studied in geophysics, these studies have been reviewed along with the studies on dissipation of water waves at ocean bottoms. The mixture theory which has been employed by various researchers in continuum mechanics is also discussed within the context of this review. Then, we present an alternative approach to obtain governing equations of wave propagation in porous media from macro scopic balance equations. Finally, we present an analysis of wave propagation in fractured porous media saturated by two immiscible fluids.
