The dynamic relationship between grain size and beach face slope, obtained by applying the law of constrictions to sediment transport in the upwelling area, was used to compare the characteristics of coral reef beaches.
In the relationship between grain size and shape, a negative correlation was observed in coral reef beaches, where Rc increased with decreasing grain size, and the opposite positive correlation was observed in sandy beaches. The analysis of sediment grain size and beach face slope showed that when the beach type was changed to reflective or deviatoric, there were differences in grain size and foreshore gradient between coral reef and sandy beaches, and these differences were attributed to the grain size distribution of the beaches.
