Resumen
This study aims to establish the effective construction scheme of the rubble mounds which are constructed by discharging a large amount of rubble from hopper barges. The numerical simulation technique is developed to estimate the spatial geometry of individual rubble mound discharged from a hopper barge. The effective distance between the discharge sites of the barge which makes the uneven property of the mound surface a minimum is discussed in connection with the change in the spatial geometry of the discharged rubble, the water depth and the direction of barge allocation.
