Fig. 8: Deformation modes under flooding cases 1 m, 2 m and 3 m for the sound column and decayed column.

(1) The deformation at top is 1.23 cm for the sound column under 1 m flooding. (2) The deformation at top is 4.93 cm for sound column under 2 m flooding. (3) The deformation at top is 11.08 cm for sound column under 3 m flooding. (4) The deformation at top is 2.3 cm for decayed column under 1 m flooding. (5) The deformation at top is 9.2 cm for decayed column under 2 m flooding. (6) The deformation at top is 20.07 cm for sound column under 3 m flooding. After Fahmy48.
