For the scour protection against local scouring phenomena in the foundation of monopile offshore wind farms, there are still many quantitative studies on the necessary scour protection area. In addition, it is necessary to consider the scale effect in hydraulic model experiments dealing with geomaterials. In this study, we conducted experiments at two different scales, 1/65 and 1/130, compared to the previous large-scale experiment at 1/13 scale. From the experiments, the appropriate similarity law for the geomaterials including the scour protection works was confirmed, and the effectiveness of the scour protection works was discussed. The scour depths of each experiment were compared based on the similarity of the sedimentation rates, and the results showed that the experiments were reproducible. It was also found that a scour protection radius of about 1.5 times the diameter of the monopile was sufficient to counter the effects of the flow alone.
