Sorting effect of sand of mixed grain size was investigated by a movable bed experiment under the condition with dominant longshore sand transport. In a plane wave tank of 4m width, a model beach of the slope 1/10 and composed of mixed sand, d50 of which are 0.2mm and 2mm, was made and waves were incident obliquely. Mixed rate of fine and coarse sand is 1:1. Sorting effect by longshore sand transport was confirmed and experimental results were compared with the numerical simulation using the one-line model considering sorting of each grain proposed by Kumada et al. Predicted results agreed with the experimental results.
