    This study examined the safety factors of piping according to changes in the heights of levee and water level, and changes in slope gradient. We also examined the safety factors after installing the cut-off wall in unsafe cases. The following are the results of this study. (1) In cases of levees with the same slope gradient, the appropriate depth of the cut-off wall became deeper as the heights of levee and water level rised. (2) When the heights of levee and water level were set constant, the appropriate depth of the cut-off wall became shallower as the slope became steeper. The slope gradient became less effective as the depth of the cut-off wall became deeper. (3) When the levees height was constant, there was a tendency for hydraulic gradient to decrease almost in the same rate as the height of water level became lower by 1m. (4) To determine the depth of the cut-off wall, the effects of the heights of the levee and water level turned out to be greater than the effect of slope.
