Optimizing tailings dam safety: integrating human factors and evolving hazards


Table 3. Example of the good, the bad, the ugly, to show the impact on the results using the methodology described in Figure 3


6.2. Comparative results (good, bad, ugly) As shown in Figure 4, the “good” dam lies at the bottom of the world-wide benchmark range, the “bad” dam at the top of the same range and finally the “ugly” is above the benchmark upper bound[20]


.


Figure 4. Estimated annualized probabilities of failure It is interesting to compare the composite scenarios (Table 4, sunny day, extreme rain, etc.) among the


three dams. as well as the relative causalities (Table 5). Note that the causalities are relative values and always add up to 100% by definition.
