For ocean application, a High Order Spectral (HOS) method is studied. Different frommost application of HOS method which use initial value problem to investigate the spectrumevolution, embedded wave generation is implemented to assess the HOS methodwith the wave tank experiments. The HOS method is also extended for non-uniformbathymetry to handle wave steepening during propagation from deep to shallow water.The enchancement of rogue wave occurence due to bottom topography is studied by consideringirregular waves propagation over a sloping bottom. Furthermore, the increasinguse of Computational Fluid Dynamics (CFD) in ship and offshore structure analysis requiresan accurate water particle kinematics for the input. Therefore, the calculation ofwater particle kinematics is investigated.
