Modeling Coastal Freak Wave Occurrence

Fishermen frequently suffer accidents and may even drown when they are swept into the sea by coastal freak waves near shore of northeastern Taiwan. To accurately predict deformation free surfaces violently strike structures, smoothed particle hydrodynamics (SPH) model with a nonlinear mesh-free numerical approach was adopted in this study. Eight cases based on an actual wave accident were simulated. The results show that maximum splash height breakwater dependent not only incident but also existence armor blocks. block installation reduces overflow discharge enhances horizontal throw speed more than five times.
