Risk Informed Decision Making
Improving how we manage risk
Stantec has significant experience in applying Risk-Informed Decision-Making (RIDM) for dam owners around the world. Our teams understand the RIDM process and how to apply qualitative and quantitative approaches to assess and manage risk versus the more traditional standards-based approach (SBA) for an improved understanding of the safety of a dam.
The SBA has served the objective of dam safety well and is still an important component of prudent dam safety practice. However, the RIDM approach provides an improved understanding of the safety of a dam through the systematic analysis of the logic of potential failure mechanisms and evaluation of consequences, and a means to analyze and assess risks in areas where traditional standards are not established.
RIDM supports the development of targeted and tailored mitigation measures to prioritize the highest risks first so resources can be more efficiently allocated to improve dam safety.
Safeguarding our communities from future flooding eventsWith estimated damages exceeding $5 billion, 32 states of local emergency declared, and communities ordered to evacuate, the 2013 Southern Alberta flood was one of the costliest and most devastating natural disasters in Canadian history. Drawing on our safety expertise, Stantec’s solution diverts river water to an off-stream storage reservoir during extreme flood conditions. Later, after the flood peak, this excess water is released back into the river, a solution that will protect the surrounding communities for decades to come. Read More
Protecting a water supply for the next 50 years and beyondIt started with the inspection of the century-old Kentucky River Lock and Dam No. 9. We assessed the structure and looked at the above-water conditions, conducted dive inspections, and took samples. Our dam safety experts evaluated multiple dam raising alternatives, conducted a flood study of the river, and provided a structural analysis of the lock and dam components. Our recommendation? A new upstream dam. Read More
