| This research was carried out to decide both in the field and the laboratory the similarity between the erosion and the accretion in the change of the beach profile. The results obtained were as follows: (1) It was impossible to decide only by C value the similarity between the erosion and the accretion of the actual beach by application of Horikawa's theory. (2) It was difficult to decide the similarity only by values of $H_//L_0$ formula. (3) Observation of dimensionless value of $H_//L_0$ and C, $H_//L_0$ and $L_{sr}$ in the field and the laboratory showed that there was a similarity between the erosion and the accretion which set in at 0.024 of $H_//L_0$. (4) The Knowlege of the wave steepness would help to discriminate the erosion and the accretion. |
