One of the natural solutions to counteract the waves is using of coastal forest cover (Green Belt). Therefore, the focus of this study is generally to evaluate the impact of green belt on attenuation the effect of solitary waves at the presence it. Research experiments aimed at evaluating a mangrove tree effectiveness to reduce tsunami energy, by using simulated shrub structures, for two tree layouts with longitudinal intervals in transverse, different cover widths and different input wave heights. Wave-induced force to the coast and green belt was calculated by direct measurement and using an electronic force meter (load cell) mounted in front of the movable part of the flume and also the wave velocity were measured via an acoustic doppler velocity meter (ADV). The experiment results showed that the presence of green belt leads to 71.27% reducing the wave destructive force and 91.52% increasing the wave attenuation. Also, was presented the proposed equation for estimating of drag coefficient with the correlation coefficient of 0.84.
