A physical modeling and full-scale testing of floodwalls is a challenging task. The challenge comes from stimulating the actual loading conditions of a flood during which water covers a vast area. The tests performed even at full-scale, in terms of wall height and water levels behind the wall, would not be a full-scale when loading conditions considered, because only limited amount of water can be used to simulate flooding. The size effect of the flooding conditions was studied using finite element method, were compared to a full-scale field test data performed by others previously. A finite element analysis tool capable of modeling soil-structure interaction, nonlinear soil behavior, and loading sequence, was used for numerical study. The numerical analyses results and the size effect on the behavior and soil-structure interaction during the flooding conditions are discussed.
