“…As the complexity of wave models increases, in pursuit of more precise simulation results for wave surfaces, Computational Fluid Dynamics (CFD) methods have gradually evolved, including Smoothed Particle Hydrodynamics (SPH) [26], Finite Volume Method (FVM) [27], and others. Gao et al carried out the research on the transient gap resonance with consideration of the motion of floating body by using OpenFOAM [28] and Gong et al simulated the transient fluid resonance phenomenon within the narrow gap between two adjacent boxes, which is excited by incident-focused waves with various spectral peak periods and focused wave amplitudes [29].…”

Ocean waves are one of the leading environmental factors that cause motion of the ocean’s structure. Wave prediction is of great significance for the safety of marine structures. The deterministic sea wave prediction (DSWP) has been focused on because it provided an accurate temporal wave surface. The propagation velocity of wave components is one of the critical problems in DSWP. In this paper, the research of propagation velocity is focused on. The Taylor expansion to wave number is used to prove that the group velocity is the propagation velocity of wave components. The simulated irregular long crest wave data is generated. Utilizing the simulated data, the calculated wave surfaces based on group velocity are consistent with the simulated results. Meanwhile, the comparisons of calculated results based on the group velocity and phase velocity are given. Then, a tank experiment is set to verify the prediction results. To further investigate the prediction performance under different conditions, the influences of environmental factors, including the wind speed, water depth and sea state are analyzed in this paper.

This study illustrates the full-scale 3D numerical simulation of the coupled water-landslide dynamics of the 1963 Vajont catastrophic event. The focus is given to the early phase of the event when about 270 million cubic meters of rock fell into the reservoir within an estimated runout time of about 25 seconds. A complex surge wave system developed throughout the basin in the first 40-55 seconds, producing maximum run-up of 270 m above the dam crowning. The mesh-free Lagrangian weakly compressible Smoothed Particle Hydrodynamics (WCSPH) method is adopted to discretize and solve the coupled system of governing equations for the landslide and water dynamics. The novelties regard the validation of a derived model and the influence of water saturated soil on prediction of surge wave run-up. The average values from technical literature are assigned to mechanical parameters without tuning or calibration. The maximum flooding on the opposite side of the valley and the peak flow rate of the discharge hydrograph through the dam section show good agreement with reference data and improvements with respect to published results. The validated derived model proves to be a promising engineering tool for quantifying the level of risk in analogous applications.
