About the Presentation:

With the ever-increasing age of dams and levees throughout the country, owners must prioritize their limited resources for regular maintenance and rehabilitation of these critical infrastructures. Often, owners are required by regulations and laws to perform risk analyses of their facilities; however, this can be a beneficial process to those not regulated, too. As the industry now has several years of experience performing risk assessments across the United States, the process has become streamlined and accessible to all dam and levee owners, not just those required by law.

Utilizing risk-informed decision-making to evaluate the safety of dams and levees provides a systematic process for identifying and understanding the risks of dams, levees, and related facilities and enables owners to prioritize dam safety management actions in efficient and meaningful ways. During this webcast, we will introduce (or reacquaint) participants to the risk-informed decision-making practice as it relates to dams and levees. We will review the history of dam and levee risk analysis and describe the various types of risk analyses owners can perform based on their individual concerns, priorities, and regulatory requirements. The data needs, risk analysis workshop process, and next steps following risk analyses will be discussed.

Following this webcast, attendees will be able to:

  • Learn the key benefits of performing risk analyses related to dams and levees, whether regulated or not.
  • Differentiate between the different levels of risk analyses and have a better understanding of which type is the best suited to the owner based specific concerns, priorities, and/or regulatory requirements.
  • Understand the risk analysis workshop process.
  • Have awareness of the resources needed to successfully execute a risk workshop.
