Probabilistic Flood Hazard Assessment (PFHA) Research Workshop – 2022

On this page:

On February 15-18, 2022, the Nuclear Regulatory Commission's Office of Nuclear Regulatory Research (NRC/RES) will host the 7th Annual NRC Probabilistic Flood Hazard Assessment (PFHA) Research Workshop. Presenters will include staff and contractors from the NRC, as well as participants from federal agencies, industry, and other domestic and international organizations. Presentations will provide information on current activities, recent results, and perspectives on future research directions in flood hazard assessment, flood protection/mitigation, and flood risk assessment. In addition to flooding, the workshop will include discussion of non-seismic external hazards such as extreme temperatures and high winds. This four-day workshop will be held virtually and is open to the public at no charge. Workshop sessions are planned to run from 10am to 5pm (EST) each day.  Registration Deadline has been extended to February 7, 2022. 

Workshop Topics:

  • Climate and precipitation 
  • Site-scale, riverine, and coastal flooding
  • Modeling frameworks
  • Flooding events and operational experience
  • External flooding probabilistic risk assessment
  • Other (non-seismic) external hazards 

Registration and Abstract Submission

Call for Abstracts: This workshop will feature both invited and submitted presentations related to the topics listed above. Abstract and poster submission deadline has been extended to January 17, 2022.
