Abstract

<p> In this research, a laboratory experiment of sand leakage into the mound of wave dissipating blocks was conducted in the scale of 1/100.</p><p> Afterwards, the result was compared with the large-scale experiments conducted in previous studies. However, sand leakage observed differed considerably between the different scale experiments; sand leakage in the large scale was not generated in the laboratory experiment. Moreover, from further research, it was revealed that the ratio of grain sizes to sand layer of the mound is a significant parameter for sand leakage to occur.</p>
