India dam break Facebook and fake news

24-02-2021

India dam break Facebook and fake news finds its inspiration in a series of very recent events. Very unfortunately one of them, the Rishiganga dam collapse (https://www.bbc.com/news/world-asia-india-55969669), was mortiferous.  World-wide water storage structures are ageing A report by UNU-INWEH,  Ageing Water Storage Infrastructure: An Emerging Global Risk, provides an overview of the phenomenon. Indeed tens of thousands of existing large dams have reached 50 years of age. In addition, many others will approach 100 years. For instance, UK has the…

Factor of Safety and probability of failure of geostructures

10-02-2021

Today we discuss the Factor of Safety and probability of failure of geostructures. We presented this discussion  at TMW 2020 and are delighted to share with you our talk.    This information is applicable to dams as well as dumps and pit slopes. However that requires the analyst pay attention to the specific details pertaining each type of structure. Factor of safety and probability of failure of geostructures The Factor of Safety (FoS) measures the ability of a structure to…

The eternal confusion between tailings hazard and risks

3-02-2021

A comment to a blogpost on tailings failures inspired this comment on the eternal confusion between tailings hazard and risks. Some voices are rising to state that the real number of tailings dams on the planet is around 35,000. Based on that number they then engage in a biased risk discourse. Indeed, we think those arguments are misleading and not helping the cause of tailings risk reduction. Let’s discuss why. The true number of tailings dams on the planet The number…

Risk assessment and automation bias

27-01-2021

In these days of AI, IoT and other technological developments Risk assessment and automation bias have to be discussed. The definition of Automation bias covers the propensity users have to favor suggestions from automated decision-making systems. Victims of automation bias will ignore contradictory information made without automation, even if it is correct. Automation bias is the last of a long dynasty Automation bias is heir to a dynasty of biases based on the same principle, but seemingly very different one from another,…

Convergent risk assessments

20-01-2021

Convergent risk assessments integrate areas that are significant to an organization, such as operational risk generated by various hazards or compliance, within a single framework. In the meantime, convergent risk assessments suppress informational siloes and therefore tend to explicitly tackle systemic interdependencies. Convergent risk assessment A convergent risk assessment looks at a silos-free system where: physical, informational geographical, and finally logical risk information converge in a single platform. Convergent risk assessments have to be holistic by definition. We discuss the definitions…

Business as usual definition in Risk Assessment

13-01-2021

Business as usual definition in risk assessment, as defined in our day-to-day practice, is an unchanging state of affairs. That is, despite the occurrence of non-divergent hazards of any kind (man-made, natural). An example of business as usual and non divergent hazard For instance, the variability of any parameter as considered and specified in the design of a system is “business as usual”. Therefore that variability does not represent a hazard. For example, the variation of the oil price of…

Foreseeability and predictability in risk assessments

6-01-2021

The discussion of terms such as Foreseeability and predictability in risk assessments is rather common. Like usual, at Riskope we like to have an extremely clear glossary, in order to avoid blunders due to miscommunication. Foreseeability and predictability in risk assessments Foreseeability is the facility to perceive, know in advance, or reasonably anticipate that damage or injury will probably ensue from acts or omissions. A foreseeable event or situation is one that can be known about or guessed before it…
