Inside the Risk Gateway

The three parts of risk analysis

When and where will the next major flood occur? Will project bids come in under the government estimate? Will a built structure live up to its strength? How many work-related injuries can we expect on the job?

No matter where you work or what you are working on in the Corps, you face questions like these every day for which there are no easy answers. The reality is that we do not and cannot know the answers to many of the questions we run into during the performance of our jobs. What we can do, however, is to understand and manage the risks created by these uncertainties.

Risk analysis is the responsibility of every Corps employee. It is an effective way of thinking about and organizing to solve problems on the job and to address uncertainty.

This web site is your gateway to understanding the Corps model for risk analysis including, assessing, managing and communicating risk. We invite you to start by taking the one-hour online training course and then to explore other parts of the site for additional information, guidance, applications and other resources.

IWR Publishes Two Manuals on Incorporating Risk in Corps Decision Making

The Institute for Water Resources recently published two new manuals for Corps staff and other stakeholders on how to consider risk in USACE activities. These documents, “Principles of Risk Analysis for Water Resources (pdf, 4.8 MB) and “Planning Manual Part II: Risk-Informed Planning(pdf, 4.2 MB) expand upon and update prior resources and provide fresh thinking on risk-informed practices at the Corps.

With these new documents available, Susan B. Hughes, Deputy, Planning Community of Practice, USACE Headquarters, said “In recent years the Corps’ consideration and analysis of risk has evolved considerably, which leads to better analyses and smarter planning processes. These two manuals reflect our ongoing commitment to better understanding and incorporating risk in our work. I hope our colleagues and stakeholders will read and refer to these documents in planning and other activities.”
