N2 - This paper presents the numerical results of wave-structure interaction of a solitary wave propagating over a vertical thin and rigid barrier, which is a kind of submerged breakwater allowing some distance from thin barrier to free surface and to flume bottom, using the two-dimensional volume of fluid (VOF)-type numerical model named COBRAS (COrnell BReaking And Structure). To minimize the computational domain, active wave absorption inflow boundary condition is also included, which allows the inflow boundary for generating desired waves and at the same time absorbing reflected waves (Torres-Freyermuth et al., 2010). For the case of a strong breaking solitary wave, it is found the physical processes can be classified into five evolutionary phases. Particular attentions are paid to an interesting backward wave breaking behavior, vortex dynamics, the turbulent kinetic energy (TKE) properties and pressure fields.
