ABSTRACT Min, E.-H. and Koo, W., 2018. Numerical simulation of wave propagation over structures on a porous seabed. In: Shim, J.-S.; Chun, I., and Lim, H.S. (eds.), Proceedings from the International Coastal Symposium (ICS) 2018 (Busan, Republic of Korea). Journal of Coastal Research, Special Issue No. 85, pp. 966–970. Coconut Creek (Florida), ISSN 0749-0208. A wave-body interaction with semi-circular rigid structures placed on a porous seabed was simulated. Owing to the rigid structures installed at regular intervals, spatial modulation of the wave propagation due to a Bragg reflection was examined. The computational domain consisted of a potential-flow water domain and porous domain with Darcy's law interface boundary condition. Using the numerical wave tank technique, the two-domain boundary element method was developed to simulate wave propagation over seafloor structures on the porous boundary in the time domain. For various permeability constants and incident wave frequencies, wave amplitude was var...
