“…Moreover, previous studies (e.g., Gonzalez-Radriguez and Madsen, 2007;Hemer et al, 2004;Jia et al, 2007;Myrhaug and Ong, 2009;van Gent et al, 2008;You, 2000You, , 2005 investigated wave-induced sediment erosion in laboratory and in-situ experiments, field observations, and theoretical models to find the effects of waves on sediment erosion and explore the mechanisms of the dynamic response of seabed sediment to waves. Although a number of studies (e.g., Chang et al, 2006;Liu and Jeng, 2007;Liu et al, 2006;Zen et al, 1998) showed that the mechanism of waveinduced seabed instability can be classified into two major types, shear failure and liquefaction, studies (e.g., Hemer et al, 2004;Myrhaug and Ong, 2009;Tanaka and van To, 1995) about seabed sediment erosion analysis in hydrodynamic conditions mainly focused on wave-induced stresses on the seabed and evaluation of resistance strengths of given seabed sediment. Generally, forces exerted on the seabed by waves can be classified into two types, level circulating shear stress and vertical pressure, which are considered the leading factors inducing shear failure and liquefaction of seabed sediment.…”

“…The #uctuating dynamic pressure in a standing wave will penetrate into a porous seabed, induce pore water pressure, and change the state of e!ective stresses within a soil column. One major concern in this phenomenon is the consequence of the excess pore pressure and instability in the seabed, which have been reported by Zen and Yamazaki [1], Zen et al, [2], Silvester and Hsu [3] and many others. Engineers in geotechnical and coastal engineering have investigated structural failures from this cause [4,5].…”

“…The wave-induced pressure loading at the mudline causes the generation of excess pore-pressure response in the seabed, and simultaneously the variation of effective stress, which has been recognized as a dominant factor of evaluating the seabed instability. When the effective stresses between individual grains vanish because of the excess porepressure, the sediment mixture will act as liquid in either a horizontal (shear failure) or vertical direction (liquefaction), leading to a failure of seabed (Zen et al, 1998). The liquefaction can generally be categorized into two types (Sumer and Fredsøe, 2002): the residual or build-up excess pore-pressure due to cyclic shear stresses (e.g., Clukey et al, 1985a;Foda and Tzang, 1994;van Kessel and Kranenburg, 1998;de Wit and Kranenbury, 1996), and the transient or oscillatory excess porepressure characterized by amplitude attenuation and phase lag (e.g., Yamamoto et al, 1978;Nago, 1981;Clukey et al, 1985b;Tzang and Ou, 2006;Tzang et al, 2009).…”
