“…For x/h = 3.0, the agreement is satisfactory even if the convergence is unclear, which is mainly due to the proximity to the slide impact zone where non-linearities and multi-phase effects might have greater influence. These results are in agreement with similar studies using DualSPHysics (Cunningham et al, 2014;St-Germain et al, 2014).…”

“…Highly accurate simulations have highlighted the need for corrections at the free surface Lind et al, 2012); this can provide very accurate results with a timestep approximately ten times that used for WCSPH, but solving the pressure Poisson equation for large numbers of particles as used herein becomes unwieldy and difficult. Hence, the present authors use the standard WCSPH formulation as described by Gómez-Gesteira et al (2010, 2012a, 2012b as this is ideally suited for acceleration using GPUs and has been shown to be appropriate for coastal applications and tsunami investigations (Altomare et al, 2014;St-Germain et al, 2014).…”

Numerical modelling by the meshless method of smoothed-particle hydrodynamics can offer quantification of tsunami wave pressures at a greater level of detail and accuracy than existing empirical methods, enabling more effective design solutions to be derived. In this paper, smoothed-particle hydrodynamics modelling of tsunami wave and structure interaction is undertaken to derive the time histories of wave pressure distributions, which can then be used by way of finite-element software to evaluate the structural response. In a series of comparative studies with physical models, the numerical results show good agreement with the experimental data. The research in this paper forms part of a wider investigation that aims to address the issue of improving resilience of shore-based structures in tsunami events.

“…There have been limited systematic works dedicated to the SPH application in this field. The most recent work of St-Germain et al (2014) pioneered the SPH to investigate hydrodynamic forces generated by a rapidly advancing hydraulic bore and also Farahani et al (2014) applied the 3D SPH modeling concept for a bar/rip channel system. However, 3D bore characteristics are scarcely revealed, which is definitely an important forte of the SPH.…”

The paper presented a Smoothed Particle Hydrodynamics (SPH) method to study the three-dimensional (3D) tidal bore scenarios. The SPH method is a mesh free particle modeling technique that can track the large deformation of free surfaces in a straightforward and accurate way. Two benchmark cases of the tidal bore propagation were computed and compared with the experimental results. The first one is related to the undular and breaking bores in a regular open channel and the second one considers the undular bore passing through the contraction of bridge piers. Physical laboratory experiments have also been carried out to validate the numerical investigations. The comparisons of both the free-surface profile and velocity field demonstrated that the SPH technique could provide a very promising tool to simulate tidal bore phenomena in engineering practice. The work is the first to systematically explore the potentials of mesh-free SPH modeling approach in predicting the tidal bore features under 3D flow conditions.
