The Multiple Accounts Analysis (MAA) method presented in this paper provides a sound basis for presenting, discussing and exploring differences of opinion (between stakeholders) in the analysis and decision making for a preferred alternative (e.g. tailings impoundment site) based on an alternatives selection process.
Risk-Informed Decision-Making (RIDM) is a method of dam safety evaluation that uses the likelihood of loading, system response given the loading, and consequences of failure to estimate risk. This risk estimate can be used to inform decisions regarding dam safety investments. This approach has many benefits including a greatly improved understanding of the safety of the dam and identifying dam safety vulnerabilities that have not been identified using standards-based evaluation techniques. This website includes dam safety guidelines to evaluate consequences of failure and is intended for use on water dams.
