Wave-Induced Seabed Instability around a Breakwater
Publication: Coastal Structures and Solutions to Coastal Disasters 2015: Resilient Coastal Communities
ABSTRACT
In this paper, an integrated model is proposed to investigate the wave-induced seabed stability around a breakwater on a sloping seabed. In the present model, the Volume-Average/Reynolds Averaged Navier-Stokes (VARANS) equations are used for wave simulation, while the Biot’s poro-elastic equation is used to govern the soil model. Unlike previous studies, pre-consolidation due to hydrostatic and the structure are considered in this model. Based on the proposed model, the effects of wave characteristics and seabed slopes on the wave-induced seabed instability (including liquefaction and shear failure) in the vicinity of a breakwater are investigated. Numerical results indicate that the wave-induced seabed instability is more likely to occur in a steep slope and under large wave loading.
