N2 - A recent paper Kelly et al. (2015) [SIAM Journal on Scientific Computing 37 (3), B403-B424.] detailed a full particle Particle-In-Cell solver for incompressible free surface flows with two-way fluid-structure interaction called PICIN. In this paper, a 2D version of the method is adapted for simulating the flows encountered in the vicinity of coastal structures. Wave generation and absorption techniques within the hybrid Eulerian-Lagrangian framework used by PICIN are developed for this purpose. The PICIN model is validated against data from three benchmark experiments: i) wave shoaling over a submerged bar, ii) wave overtopping of a Low Crested Structure (LCS) and iii) dam-break induced overtopping of a containment dike. A realistic engineering scenario is also presented that demonstrates the modelling of two-way fluid-structure interaction. The validation study demonstrates that the PICIN model is able to simulate the significant flow processes occurring during wave propagation and transformation, wave impact, overtopping and two-way fluid structure interaction, using relatively little computational resource.
