Description
The webinar will describe the process of developing seismic thresholds for 50 selected embankment/rockfill dams in the Western U.S. for post-earthquake notification and response. This work was extrapolated to approximate the return period of the permanent displacement failure for each dam. Seismic hazard curves for dams in low and high seismicity areas will be compared to evaluate whether a ‘levelized’ return period, e.g. 10,000 years, would provide the desired level of consistency and conservatism when evaluating ground motions for dam safety.

Justin F. Smith, P.E. is a Senior Civil Engineer in the Division of Dam Safety and Inspections at the Federal Energy Regulatory Commission in Washington, DC. Justin is an agency subject matter expert in the fields of seismicity and geotechnical engineering. Justin’s primary responsibilities include the seismic hazard analysis of hydropower projects including dams, powerhouses, and appurtenant features. Additionally, Justin assess the dynamic performance of earth embankment and rockfill dams and their foundations for liquefaction susceptibility, deformation, and post-earthquake stability.
