Abstract
This study numerically investigates how an artificial reef affects wavecurrent fields using a 3-d direct numerical model. The numerical results reveal that wave-current co-existing field is considered to investigate the effect of wave-current interaction on wave fields around an artificial reef installed at river mouth., Wave-current interaction greatly influence the energy flux with a resulting increase in wave height behind the artificial reef and the energy flux mechanism is significantly different between permeable and impermeable artificial reefs.
