Effect of the shore green belt on reduction of wave height and energy of the attacking waves is studied. Experiments are conducted for two patterns, triangular spaced 5 × 5 and 10 × 10 cm, 3 width of 10, 30 and 40 cm, 5 shore slopes of 0, 3, 5, 7 and 10% and 5 wave heights of 1/5, 3, 4, 6 and 8 cm. In total, 325 different cases were examined. Dynamic pressure was measured at several points of the shore model by pressures transducer. The wave force absorbed by the green belt was measured directly by a system of load cell. Results showed a considerable effect of green belt on reduction of wave height and energy. For all of shore slopes, the maximum of momentum absorption and wave height reduction was in 5×5 pattern and width of 40. The force absorption for spaced 5 × 5 was more than 10 × 10. The average rate of force absorption, between 5 × 5 and 10 × 10, was 1/3.
