Abstract: A novel free-surface immersed boundary-lattice Boltzmann method for wave–structure interaction and hydrodynamic force estimation is introduced. The free-surface lattice Boltzmann method is coupled with the immersed boundary modification in order to simulate rigorous free surface wave and to evaluate the exact hydrodynamic forces on a breakwater. First, the proposed model is applied to incident wave propagation in a shallow water zone. The wave–breakwater interactions and wave forces on a breakwater are then analysed using the method. The results agreed with those of Goda’s formulae, confirming that the proposed model has a high potential for application to complex analysis of coastal engineering problems.
