 To determine the beach profile evolution of gravel beach under the irregular waves, the hydraulic experiments were conducted. A gravel beach with a slope of 1/7 was installed and the change of spatiotemporal profile according to the irregular wave was analyzed during 6 hours. Two types of beach profile deformation (reflective/step type) occurred under the accretive wave condition and it can be distinguished using discriminant equation of surf-scaling parameter with the representative wave information of irregular wave (H5% and Tp). In addition, it was revealed that the similar profile deformation can be reproduced by replacing the irregular wave with the regular wave on the gravel beach, when the regular wave has the same wave information with the representative wave (H5% and Tp).
