The stability of embankment dams can be affected by many factors including the extent of long-term steady-state water level. Unfortunately, analysis of such a problem in-situ cannot be easily achieved due to time constraints and the complexity of the influencing factors. This study investigated the potential influence of changes in long-term water level on slope stability of an embankment when subjected to a rapid drawdown using numerical modeling. Three different water levels were investigated (10m, 8m, and 6m). To avoid variability and capture the effect of the long-term water level, the geometry of the reservoir was kept constant.
