Yes / This research paper presents an incompressible smoothed particle hydrodynamics (ISPH) technique to investigate a regular wave
overtopping on the coastal structure of different types. The SPH method is a mesh-free particle modeling approach that can
efficiently treat the large deformation of free surface. The incompressible SPH approach employs a true hydrodynamic formulation
to solve the fluid pressure that has less pressure fluctuations. The generation of flow turbulence during the wave breaking and
overtopping is modeled by a subparticle scale (SPS) turbulence model. Here the ISPH model is used to investigate the wave
overtopping over a coastal structure with and without the porous material. The computations disclosed the features of flow velocity,
turbulence, and pressure distributions for different structure types and indicated that the existence of a layer of porous material
can effectively reduce the wave impact pressure and overtopping rate. The proposed numerical model is expected to provide a
promising practical tool to investigate the complicated wave-structure interactions. / Nazarbayev University Seed Grant, entitled “Environmental assessment of sediment pollution impact on hydropower plants”. S. Shao also acknowledges the Royal Society Research Grant (2008/R2 RG080561)
