Abstract
The purpose of this paper is to present a scale-model relationship for similarity between full-scale and scale models of two-dimensional equilibrium beach profiles. A similarity comparison between full-scale and small-scale model is made by considering the degree of experimental error. The similitude obtained is graphically shown, and the scale-model relationship is also formulated. It is found that the small-scale relationship agrees with the ones derived from shoreline change, critical water depth of sediment movement, and beach profile.
