... loads cannot be ignored (Sumer, 2006; Jeng, 2018). However, the relationship between strong nonlinear waves such as breaking waves and the dynamic seabed response has not been clear. On the one hand, by adopting numerical methods, the physical problems involving monopiles on the hydrodynamic wave...

... in the pore pressure changes (Yamamoto et al., 1978). This type of seabed liquefaction is caused by the wave-induced seabed seepage near wave troughs (Jeng, 2012). The second mechanism is termed as the residual pore pressure, which is the build-up of excess pore pressure caused by contraction of the soil...

...). In general, when the seabed is exposed to the wave, the generated dynamic pressures along the seafloor can induce the pore pressures, effective stresses and soil displacements within the seabed (Jeng, 2012). Then, the seabed in the vicinity of the pipeline could become unstable or even liquefied due...
