Abstract
Laboratory experiments were performed to study the wave forces acting on model plants on the bedof two dimensional wave flume. The wave forces acting on the both directions of wave propagation(inline dirction) and gravity were measured by using a two components load cell installed under the bed ofwave flume. The influence of the ratio of plant height and water depth to the wave forces were evaluated.The drag and inertia coefficients of Morrison equation applied to the analysis of in line forces were obtained.The damping of waves due to the crowd of model plants are also evaluated.
