... ABSTRACT The wave impact on piers is a concerning problem for coastal bridges. In this study, the coastal bridge pier is simplified to a two-dimensional fixed submerged obstacle, and the solitary wave interaction with it is simulated by the Smoothed Particle Hydrodynamics (SPH) code SPHinXsys...

... is important for coastal engineers and planners. The main characteristics as water waves propagating over a submerged obstacle are the process of the reflection, dissipation and transmission. Especially, coastal engineers care about the transmitted wave and the protection for coastline. For these reasons...

... wave transmission. The leading crest and leading trough deform slightly due to shoaling effect when the wave passes on the front slope of the submerged obstacle. As the wave approaches the front slope, the flow in lower layer increases because of the narrow width between the leading trough and front...
