Damping effects of ship waves by an emergent vegetation community have been investigated with numerical simulations based on Boussinesq-type equations. The resistance due to the emergent vegetation community is modeled by wave forces on a group of vertical cylinders. The applicability of the numerical model is confirmed by comparing with experimental results on the wave damping by a group of vertical cylinders in a laboratory flume and field observation data on the maximum height of ship waves. The numerical simulations demonstrate that ship waves on a sloping bottom are significantly damped by the emergent vegetation community on a shoaling and surf zone.
