15 Risk-Informed Decision Making
Tolerance
Fig. 15.12 The effects of mitigation on the risks of the interdependence of Dam 2 on Dam 3
might include moving the population, enhancing the protection to the environmental
damages, lowering the dam, etc.
Here the test of negligence would indicate a necessary investment of $1 M/year,
because the factual risk is small. However, the intolerable part of the risks, and the
fact they are of a strategic nature, would induce the owner to mitigate more.
Thanks to the quantitative approach strategic shifts can be evaluated. We will
discuss in the next Sect. 15.9.4 the potential impacts on human life and see how
these would alter these initial considerations.
