Effects of Rapid Water-Level Fluctuations on the Stability of an Unsaturated Reservoir Bank Slope

Figure 6

Potential sliding zone (green part) of Case 2 with water-level increases from 672.5 m to 765 m at a rate of 2 m/day, considering the hydromechanical coupling effect, and the suction force is considered (F_S = 1.255).
