A river levee is an essential flood defense structure. Progressive sliding failure with large deformation is a serious problem which has a possibility to lead to a river levee breach. The SPH method is used for simulating the results of model experiments, which progressive sliding failures were observed. The results of calculation represent the progressive sliding failure with a proposed soil-water coupling. The results also illustrate the diffirence in the process of failures according to the height of a pheriatic line. Besides, it has a possibility for a river levee to lead to progressive sliding failure by the destruction of soil skelton structure at the toe by seepage or the contraction by insufficient compaction from the results of the numerical simulation.
