The Next Generation Attenuation (NGA) program released three subduction ground motion models (GMM) as part of the NGA-Subduction (NGA-Sub) project in 2020. These GMMs are applied in probabilistic seismic hazard analyses (PSHA) and deterministic seismic hazard analyses (DSHA) for four dams in Cascadia, which are classified as “High Hazard” under Federal Energy Regulatory Commission (FERC) guidelines.

Seismic Hazard Assessment for High Hazard Dams in Hawaii

Chief Geotechnical Seismic Engineer
Connect on LinkedIn
Seismic hazard assessment of the dams classified by the Hawaii Department of Land and Natural Resources as high hazard was designed to increase dam safety and advance the field of seismic hazard in Hawaii. Safety evaluation earthquakes were developed and can be used for future stability analyses of these high hazard dams.
Semi-Quantitative Risk Analysis Of The Yelm Canal, City Of Centralia
TUESDAY, APRIL 12 • 4:45 P.M.

Dean B. Durkee, PhD, PE, PEng
Vice President, Senior Consultant and West Regional Manager Geotechnical, Dams, and Hydraulics
Connect on LinkedIn
At the City of Centralia’s Yelm Canal, which is part of the Yelm Hydroelectric Project, the risk driver Probable Failure Modes (PFMs) are related to internal erosion and seepage. Because of the identified risks, FERC restricted canal operations to no more than 300 cubic feet per second (cfs). For the canal to generate sufficient power to be economically feasible, at least 600 cfs is required. Seven PFMs require risk reduction measures to enable the canal to operate at or above 600 cfs.
